La Sulla fresca o disidratata migliora le proprietà salutistiche dei formaggi ovini

2022

Nel settore dell’alimentazione dei ruminanti si registra un crescente interesse verso l’uso dei polifenoli per i diversi vantaggi che ne conseguono, fra i quali, l’ottimizzazione delle fermentazioni ruminali, con conseguente riduzione della metanogenesi e mitigazione delle emissioni di metano nell'ambiente; la riduzione della degradazione delle proteine alimentari nel rumine, favorendo quindi una maggiore disponibilità di aminoacidi per l'assorbimento intestinale e la riduzione delle escrezioni di azoto nell'ambiente; la protezione degli acidi grassi polinsaturi (PUFA) dalla bioidrogenazione del rumine, e il loro successivo trasferimento nei prodotti lattiero caseari e nelle carni che così …

Legume grain-based supplements in dairy sheep diet: Effects on milk yield, composition and fatty acid profile

2016

With the aim to find protein sources that are free of genetically modified organisms, the effects of legume grain-based concentrates, used as alternatives of a mixed concentrate feed containing soybean, were evaluated on sheep milk production. Twelve lactating ewes were divided into four groups, fed hay and, according to a 4 × 4 Latin square design, supplied with 800 g/day of a commercial mixed concentrate feed (MCF) containing maize and soybean, or the same amount of isoprotein concentrates consisting of chickpea (CH), faba bean (FB), or pea (PE) mixed with barley. The ewes ingested more of the concentrates with legume grains than the MCF (702, 702, 678 vs 587 g/day DM for CH, FB, PE and M…

Effects of adding solid and molten chocolate on the physicochemical, antioxidant, microbiological, and sensory properties of ewe's milk cheese.

2020

Abstract: A novel dairy product, namely “chocolate cheese”, was produced with two typical Sicilian food products: Pecorino cheese, processed from ewe's milk, and Modica chocolate. The cheese, manufactured with 0%, 5%, 10%, and 15% (w/w) solid or molten chocolate, was evaluated after 0, 2, 4, and 6 weeks of vacuum storage for its nutritional and health properties. The addition of chocolate reduced the pH, protein, fat, and ash; the addition of 5% or 10% molten chocolate reduced hardness (N/mm2). The addition of either solid or molten chocolate resulted in a slight increase (P < 0.1038) in the total polyphenol content, a higher oleic acid content, and less oxidative stability. The microbio…

Il mese di produzione influenza la qualità di formaggi tipici?

2022

Il settore lattiero-caseario mediterraneo rappresenta una delle più importanti attività legate al lavoro delle terre montane e marginali e alla produzione di prodotti tipici e di qualità. Un prodotto “tipico” è il risultato di diversi fattori strettamente legati all’origine geografica e alle tradizioni sociali e culturali dell’area di produzione. Tali prodotti sono da sempre uno strumento per valorizzare la biodiversità, la cultura e l’economia di definite aree mediterranee. L’Unione Europea riconosce ufficialmente questa diversificazione di prodotto attraverso l’attribuzione di marchi di qualità a denominazione di origine protetta (DOP) e a indicazione geografica protetta (IGP). Nella poli…

Milk production and physiological traits of ewes and goats housed indoor or grazing at different daily timing in summer

2009

During a 6 week trial in summer, 3 homogeneous groups, each consisting of 5 Comisana ewes and 5 Rossa Mediterranea goats, grazed watered forage resources during day (D) or night (N), or were housed indoor and supplied with mowed herbage (H). Maximum THI peaked at 94 at the end of July, and was almost constantly higher of 80. Milk yield was higher in N than in D and H goats, whereas N ewes produced more milk than H group, but their milk yield was higher than D ewes only in the period with the highest THI values. The lower urea in N goat milk, and the higher casein in N ewe milk, seem to indicate a better efficiency in dietary nitrogen utilization of night grazing animals. N ewes showed lower…

2020

Abstract The present work was carried out to evaluate the microbiological and physicochemical composition of salamis produced with the meat of beef, horse, wild boar and pork. Salami productions occurred under controlled laboratory conditions to exclude butchery environmental contaminations, without the addition of nitrate and nitrite. All trials were monitored during the ripening (13 °C and 90% relative humidity) extended until 45 d. The evolution of physicochemical parameters showed that beef and pork salamis were characterized by a higher content of branched chain fatty acids (FA) and rumenic acid than horse and wild boar salamis, whereas the last two productions showed higher values of …

Effects of Grazing on the Behaviour, Oxidative and Immune Status, and Production of Organic Dairy Cows

2019

This study compared the effects of a short daily grazing time with those of permanent free-stall housing on the behaviour, oxidative status, immune response, and milk production of organically reared cows. During a 63-day period, two homogeneous groups of eight lactating Brown cows were allocated to either housing (H) in a free-stall building for 24 h/day. Feeding was based on a total mixed ration or grazing (G) on barley grass for 5 h/day, and housing in a free-stall structure with feeding was based on the same total mixed ration offered to the H group. With regard to behaviour, H cows spent more time idling, walking, drinking, and self-grooming, whereas G cows showed a greater intent to e…

Effect of legume grains as a source of dietary protein on the quality of organic lamb meat.

2011

BACKGROUND: This study evaluated the effects on lamb growth, carcass traits and meat quality of replacing conventional soybean meal in the diet with alternative legume grains. RESULTS: Twenty-eight male lambs of Comisana breed weighing 16.9 ± 2.7 kg at weaning (66 ± 6 days old) were assigned to one of four diets. Until slaughter at 129 ± 6 days of age, each group received ad libitum pelleted alfalfa hay and concentrates differing in the source of protein: chickpea, faba bean, pea or soybean meal. Lambs fed chickpea showed higher dry matter and protein intakes from concentrate than those fed soybean. Lambs' growth, carcass weight and net dressing percentage did not vary by protein source, al…

Fatty Acid Composition of Salami Made by Meat from Different Commercial Categories of Indigenous Dairy Cattle

2021

Simple Summary The Cinisara is a Sicilian breed raised on pasture to produce the Caciocavallo Palermitano cheese. Even if it is penalized by competition with meat breeds, characterized by higher growth rate and yield, the production of fresh meat represents a considerable added value for the smallfarms. The meat of Cinisara is not appreciated, despite having a high content of iron, vitamin E, conjugated linoleic acid (CLA), and low content of lipids and cholesterol, above all due to incorrect management of the supply chain phases that negatively affects the quality of the final product. Alternative production such as bresaola and salami could contribute to the enhancement of Cinisara meat. …

Effects of continuous and rotational grazing of different forage species on ewe milk production

2012

Abstract The aim of this research was to evaluate the effects of continuous and rotational grazing of different forage species on milk production in ewes. The forage species were chicory (Cichorium intybus L.), a mixture of oat (Avena sativa L.) and berseem clover (Trifolium alexandrinum L.), and sulla (Hedysarum coronarium L.). Forty ewes were divided into 5 groups, and subjected to one of the following treatments: continuous grazing on chicory, continuous grazing on the mixture, continuous grazing on sulla, rotational grazing on the mixture, or rotational grazing on sulla. Among the species continuously grazed, chicory showed a lower biomass than the mixture, or sulla. Ewes grazing chicor…

Effects of different genotypes at the CSN3 and LGB loci on milk and cheese-making characteristics of the bovine Cinisara breed

2017

The Cinisara is an autochthonous Sicilian bovine breed reared mainly for production of Caciocavallo Palermitano, a typical stretched-curd cheese. The distribution of A and B alleles at both the β-lactoglobulin (LGB) and κ-casein (CSN3) loci in Cinisara cows and their influence on milk traits and cheese yield and composition were analysed. The LGB alleles are associated with significantly different effects on whey protein level (lower for BB genotype, P < 0.01), and casein index (higher value for BB genotype, P < 0.001), while CSN3 alleles were associated with significantly different effects on milk yield and coagulation properties; the BB genotype showed higher values for milk yield (…

Feeding Dairy Ewes with Fresh or Dehydrated Sulla (Sulla coronarium L.) Forage. 2. Effects on Cheese Enrichment in Bioactive Molecules

2022

Sulla is a tanniferous legume species largely used as fresh or preserved forage in the ruminants’ diets. Due to its content in polyphenols with antioxidant activity, especially condensed tannins (CT), fresh sulla forage (FSF), when eaten by ruminants, is able to enrich animal products with antioxidant molecules and polyunsaturated fatty acids (PUFA) that are beneficial for consumers’ health. Dehydration represents a valid alternative to haymaking to preserve these properties also in periods when FSF is unavailable. In this research, the effects of ewes’ diets based on sulla hay (SH), pelleted dehydrated sulla forage (DSF) or FSF were evaluated on cheese physico-chemical tr…

Neuroendocrine responses in neonatal mother-deprived rabbits.

2009

To study both short- and long-term adaptation mechanisms activated by rabbits which were separated from their mothers (DLS) for 48 h between postnatal days 9 and 11, we examined plasma corticosterone concentrations before, during, and after DLS as well as the expression of glucocorticoid receptor (GR) in the hippocampus and the adrenal axis responses to a mild stress stimuli or exogenous ACTH injection. At postnatal day 10, plasma corticosterone concentration of DLS rabbits was similar to that of controls, but rose two-fold at day 11 (17.7 + or - 1.3 vs. 9.3 + or - 1.2 microg/dl, P0.01) and then decreased at day 12, when suckling was allowed again, to match those of controls with no differe…

Relationships between dietary factors and milk urea nitrogen level in goats grazing herbaceous pasture

Effects of Grazing Season on Physico-Chemical Characteristics and Fatty Acids of Nutritional Interest of Caciocavallo Palermitano Cheese

2022

The aim of this work was to evaluate, in the different production seasons of the year, the physico-chemical quality of an artisanal cheese traditionally obtained from autochthonous grazing cows, with particular reference to fatty acids (FA) of nutritional interest that play an important role in the risk or prevention of some human pathologies. For this purpose, cheeses were sampled in 11 farms, repeating the samplings in 3 different periods of the year (summer, autumn–winter, and spring) when the productive conditions of the pastures varied. The cheeses produced in the spring period, when cows ingest a greater amount of grazed forage, resulted in a more adequate composition of the main FA, …

Meat production from dairy breed lambs due to slaughter age and feeding plan based on wheat bran

2019

This experiment aimed to investigate the possibility to increase the carcass weight of dairy breed lambs and produce moderate-fat meat by applying inexpensive feeding strategies based on restriction and through the use of a fibrous byproduct such as the durum wheat bran (DWB). Sixty-five 45-day-old lambs of the Valle del Belice breed, divided into 6 groups, were fed alfalfa hay supplemented with concentrate feeds including DWB at 0% or 20% (DWB0, DWB20), supplied ad libitum (L) or restricted at 75% (R), and slaughtered at 90 or 120 days of age. The groups were as follows: DWB0-90L (n = 14), DWB20-90L (n = 14), DWB0-120R (n = 10), DWB20-120R (n = 9), DWB0-120L (n = 9), DWB20-120L (n = 9). Th…

2015

The biofilms of 12 wooden vats used for the production of the traditional stretched cheeses Caciocavallo Palermitano and PDO Vastedda della valle del Belìce were investigated. Salmonella spp. and Listeria monocytogenes were never detected. Total coliforms were at low numbers with Escherichia coli found only in three vats. Coagulase-positive staphylococci (CPS) were below the enumeration limit, whereas lactic acid bacteria (LAB) dominated the surfaces of all vats. In general, the dominance was showed by coccus LAB. Enterococci were estimated at high numbers, but usually between 1 and 2 Log cycles lower than other LAB. LAB populations were investigated at species and strain level and for thei…

Effects of Diets Supplemented with Medicinal Mushroom Myceliated Grains on Some Production, Health, and Oxidation Traits of Dairy Ewes

2019

The beneficial properties of mushrooms’ bioactive compounds indicate their potential for use as performance-enhancing natural additives for livestock animals. A study was undertaken to evaluate the effects of diets supplemented with mushroom myceliated grains (MMGs) fed to dairy ewes on intestinal parasite load, milk production, milk fatty acid (FA) composition, and cheese oxidative stability. During an 8-week experimental period, 21 lactating Valle del Belice ewes were divided into 3 groups named MMG20, MMG10, and MMG0. Ewes in each group were fed hay ad libitum and 1.3 kg/day/head of 1 of 3 concentrates with MMGs at 20% (MMG20), 10% (MMG10), or 0% (MMG0). The ewes fed MMG20 had comparable…

Prickly Pear By-Product in the Feeding of Livestock Ruminants: Preliminary Investigation

2020

Simple Summary The question of sustainability of animal nutrition has become a popular topic. The gains made by recycling safe, yet otherwise valueless, by-products and wastes from human food and fiber production (green feeds) may lessen the competition between humans and animals for crops and decrease the environmental impact of food production. In this context, prickly pear by-product, which results from Opuntia ficus-indica (L.) Mill. fruits processed for juice extraction, could be an optimum by-product to ruminant feeding. This study evaluates the nutritional characteristics and its stability during storage using potassium metabisulfite as a preservative agent. This preliminary investig…

Utilization of mulberry leaves (Morus latifolia cv. Kokusou 21) in diets for dairy ewes

2009

Twelve Valle del Belice lactating ewes were divided into three homogeneous groups and fed ad libitum the following diets in a 3 x 3 Latin square design: sulla hay (HA); sulla hay and Mulberry leaves (M. leaves) (HM); M. leaves (MU). DM intake of MU ewes was lower than that of HM ewes, with an intermediate level for HA ewes. HM ewes showed to prefer M. leaves to hay, but their need to balance the high protein and low NDF contents of M. leaves by eating hay also emerged. Milk yield increased as the dietary content of M. leaves increased- In addition, the use of HM and MU diets led to higher milk fat and urea content in comparison with the HA diet. The results confirmed that M. leaves are a su…

Effect of muscle type and animal category on fatty acid composition of bresaola made from meat of Cinisara cattle: preliminary investigation

2020

The bresaola could represent an alternative commercial opportunity for autochthonous dairy cattle farms. Therefore, a study was carried out to investigate the fatty acid (FA) composition of bresaola made using Semimembranosus (SMm), Semitendinosus (STm), and Biceps brachii (BBm) muscles from grazing young bulls (GB), housed young bulls (HB) or grazing adult cows (AC) of Cinisara breed. Animal category, fat content, feeding system, and type of muscle influenced the FA composition of bresaola. Fatter products, made from AC and HB meat, or with STm and BBm muscles showed lower polyunsaturated/saturated FA ratio. The bresaola from young bulls fed pasture-based diet showed an increased polyunsat…

Effects of diet on casein and fatty acid profiles of milk from goats differing in genotype for αS1-casein synthesis

2013

This study investigated the interactions between nutrition and the genotype at αS1-CN loci (CSN1S1) in goats, evaluating the impact of fresh forage-based diets and an energy supplement on the casein and fatty acid (FA) profiles of milk from Girgentana goats. Twelve goats were selected for having the same genotype at the αS2-CN, β- CN, and κ-CN loci and differing in the CSN1S1 genotype: homozygous for strong alleles (AA) or heterozygous for strong and weak alleles (AF). Goats of each genotype were divided into three groups and, according to a 3 × 3 Latin square design, fed ad libitum three diets: sulla fresh forage (SFF), SFF plus 800 g/day of barley (SFB), and mixed hay plus 800 g/day of ba…

Chemical and acidic composition of Longissimus dorsi muscle of Comisana lambs fed with Trifolium subterraneum and Lolium multiflorum

2010

Aim of this study was to evaluate the effects of grazing on Trifolium subterraneum and Lolium multiflorum, as pure or associated crops, on the chemical composition and on the fatty acid profile of the intramuscular lipids of the meat of lambs. Forty Comisana male lambs, on average weighing 13.75±1.90 kg, were divided into four homogenous groups of ten and called, in relation to the diet: group T those grazing on T. subterraneum; Group L on L. multiflorum; Group TL on adjacent monocultures of T. subterraneum and L. multiflorum (66.6 and 33.3% of surface, respectively); Group LT on adjacent monocultures of T. subterraneum and L. multiflorum (33.3 and 66.6% of surface, respectively).

Feeding Dairy Ewes with Fresh or Dehydrated Sulla (Sulla coronarium L.) Forage. 1. Effects on Feed Utilization, Milk Production, and Oxidative Status

2022

Feeding dairy ewes with fresh sulla forage (FSF), a legume species containing condensed tannins (CT), has been shown to increase feed intake, milk yield, and casein and enhances the oxidative status of animals. Dehydration of FSF could be an alternative to hay-making to preserve the nutritional properties. This research aimed to compare the responses of dairy ewes fed with diets based on sulla hay (SH), pelleted dehydrated sulla forage (DSF), or FSF in terms of efficiency of feed utilization, milk production, and the balance between oxidant (reactive oxygen metabolites (ROMs)) and antioxidant (biological antioxidant potential (BAP)) substances at the plasma level. Ten first-lambing (FL) and…

Bresaola made from Cinisara cattle: effect of muscle type and animal category on physicochemical and sensory traits

2020

The physicochemical characteristics and sensory traits of Cinisara bresaola were investigated, to explore a new commercial opportunity for autochthonous dairy cattle farms. Semimembranosus, Semitendinosus and Biceps brachii muscles, from adult cows (AC) and grazing (GB) or housed (HB) young bulls of Cinisara breed, were processed to made bresaola. Differences due to animal category and muscle type were observed. Bresaola from AC was richer in fat and volatile organic compounds. The bresaola from Semitendinosus showed higher colorimetric parameters, fat and, when from grazing animals, Warner-Bratzler shear force than those made from other muscles. In general, all bresaola were well appreciat…

Improvement of Oxidative Status, Milk and Cheese Production, and Food Sustainability Indexes by Addition of Durum Wheat Bran to Dairy Cows’ Diet

2019

Durum wheat bran (DWB) is a by-product mostly used in feeding ruminants, contributing to decrease in the utilization of feeds suitable as foods for human consumption, thus improving the sustainability of livestock production. However, the potential benefits of DWB, due to its content in phenolic acids, mainly consisting of ferulic acid with antioxidant properties, have not been well clarified yet. Accordingly, in this experiment, 36 lactating cows divided into three groups received, over a period of 100 days, one of three concentrates including DWB at 0% (DWB0), 10% (DWB10), or 20% (DWB20). The concentrates were formulated to be isoproteic and isoenergetic and, to balance the higher fiber c…

The Use of Winery by-Products to Enhance the Functional Aspects of the Fresh Ovine “Primosale” Cheese

2021

Fresh ovine “primosale” cheese was processed with the addition of grape pomace powder (GPP). Cheese making was performed using pasteurized ewes’ milk and four selected Lactococcus lactis strains (Mise36, Mise94, Mise169 and Mise190) inoculated individually. For each strain the control cheese (CCP) was not added with GPP, while the experimental cheese (ECP) was enriched with 1% (w/w) GPP. GPP did not influence the starter development that reached levels of 109 CFU/g in all final cheeses. The comparison of the bacterial isolates by randomly amplified polymorphic DNA (RAPD)-PCR showed the dominance of the added strains over indigenous milk bacteria resistant to pasteurization. GPP addition red…

Effect of saffron addition on the microbiological, physicochemical, antioxidant and sensory characteristics of yoghurt

2018

The impact of added saffron on the characteristics of yoghurt was evaluated during storage. The fat content was lower in the saffron yoghurt. All colour variables were significantly affected by saffron and storage. From the 15th day of storage, bacterial numbers in the saffron yoghurt were higher than those of the control yoghurt. Sensory analysis data suggested that colour, odour and texture impacted consistently on the overall acceptability of the saffron yoghurt. Saffron addition significantly increased polyphenol content and antioxidant activity, providing evidence that the enrichment of natural yoghurt with saffron yields an innovative fermented product useful for supplementing antioxi…

The aim of this research was to evaluate the effects of grazing Trifolium subterraneum (T) and Lolium multiflorum (L), as pure or associated crops, on forage intake and milk yield and composition in Comisana ewes. The four following fenced subplots, each of 2500 m2, were used for grazing: T, 100% of surface; L, 100% of surface; TL, T and L on 66.6 and 33.3 % of surface; LT, T and L on 33.3 and 66.6% of surface, respectively. Each subplot was divided into two parcels in order to have two replicates. Forty ewes were divided into eight homogeneous groups, with regard to milk yield, days in milk and live weight. In spring for 70 days, each group grazed daily for 8 h one of the fenced parcels. M…

Effects of diet and genotype at CSN1S1 locus on the oxidative stress in lactating goats

2011

Twenty-eight Girgentana goats were selected on the basis of their CSN1S1 genotype as follows: 14 goats homozygous for strong (AA) alleles and 14 goats heterozygous (AF). The goats were used in a 2 x 4 factorial arrangement of treatments, with the two genotypes (G) and four diets (D). The diets were: a pelleted alfalfa hay (100H), a complete feed including alfalfa hay at 65% (65H), fresh sulla (Hedysarum coronarium L.) forage (100S) and fresh sulla plus barley (65S). Each trial consisted of 15d for adaptation and 8d for sample collection, during which the goats received the scheduled diet ad libitum. Blood samples were collected at the end of pre-experimental and experimental period. Plasma …

Energy intake effects at pasture on milk production and coagulation properties in girgentana goats with different as1-cn genotypes

2007

The aim of this study was to investigate whether proerties of milk from Girgentana goats of different as1-CN genotypes were affected by the energy intake at pasture. Thirty six goats were genotyped at as1-CN locus using several genomic techniques and milk protein analysis. Eight genotypes associted with low (FF, 2 goats), medium (AF, AN, BF, BN, 21 goats) and high (AA, AB, BB, 13 goats) as1-CN level have beed typed. The increase in energy intake (E) of goats from low (2.0 Mcal/d) corresponded to an increasing dry matter intake, diet CP percentage, milk yield and clotting parameters, and a reduction in milk fat. Depending on genotypes linked to increasign as1-CN, milk was higher in casein, c…

Body condition score and related productive responces in rabbit does.

2008

A simplified 3-point scale method for in vivo scoring body condition is proposed as an useful and rapid tool to support experimental and on-farm management of nutrition and reproduction of rabbit does. The productive responses of lactating rabbit does scored and inseminated at 11 days post partum (pp) are verified, as well as performance of non-pregnant does scored and re-inseminated at 32 days pp when non-lactating. After their first parturition, 96 New Zealand White rabbit does were checked for 126 days over three successive 42-day reproductive cycles. The body condition scoring was based on feel by hand the loin and the rump for bone protrusions and muscle fullness. The loin was evaluate…

The maturity stage of the grass affects milk fatty acids of cows grazing a mountain grassland

2010

International audience; We aimed to quantify the effect of the growth stage of a mountain grassland pasture on the fatty acid (FA) composition of grass and milk. In June (growth) and October (regrowth), a mountain pasture was continuously grazed by six dairy cows in a strip grazing system. During June, the grass C18:3n-3 content decreased while C16:0, c9-C18:1 and C18:2n-6 content increased. During October, the grass FA composition was similar to that observed in the first part of June. During June, milk saturated FA (SFA) content increased while the sum of the trans FA and polyunsaturated FA (PUFA) content decreased, mainly due to the decrease in C18:3n-3 and c9t11-CLA percentages. At the …

Transfer of milk fatty acids to Pecorino Siciliano cheese

2011

In previous studies it was observed that milk fatty acid (FA) composition is mainly affected by diet, and when ruminants graze pasture the percentages of polyunsaturated FA and conjugated linolenic acid (CLA) are higher than in milk from preserved forage. The maintenance in the cheese of the beneficial FA profile of milk from grazing ruminants is advisable. Little number of study exists concerning the effect of milk processing conditions on cheese FA profile, but no study was done with regard to Pecorino Siciliano cheese. The aim of this study was to evaluate the transfer of FA from ewes milk to cheese manufactured according to the Pecorino Siciliano technology, in order to verify if the ch…

Effects of grazing on welfare and production traits of organic dairy cows

2013

In organic livestock systems, grazing is the preferred feeding source, especially for animal welfare and health implications, but it is not an obliged practice. In order to contribute on this topic, in an organic dairy farm, grazing was compared with permanent free-stall housing using two homogeneous groups of eight Bruna cows allocated to the following regimes: (G) grazing on barley grass for 5 h/d, and then kept in a free-stall structure and fed with unifeed, composed of hay and concentrate; (S) kept in a free-stall building for 24 h/d and fed with a diet based on the same unifeed. Comparison was based on milk production, behaviour, immune responses, metabolic status and oxidative stress …

Quality evaluation of cheese from raw or pasteurized milk of ewes grazing sulla forage (Hedysarum coronarium L.) for different daily time

2009

Pasteurization is the more effective method for eliminating pathogens contaminating milk. However, the high temperature of pasteurization destroys either pathogens or lactic endemic flora, this latter involved in cheese ripening, thus impairing the development of sensory properties of cheese. It was previously observed that longer permanence at pasture allows the ewes to spend more time for eating; accordingly, ewes increase feed intake and milk yield. Aim of this experiment was to evaluate the effect of the prolongation of ewes daily grazing from 8 to 24 h and the effect of the milk pasteurization process on milk and cheese quality, with particular regard on fatty acid (FA) composition. In…

Effects of nutritional level on lactating response of Girgentana goats with different CSN1S1 genotype

2011

Goat polymorphism at αs1-casein loci (CSN1S1) influences milk yield and composition. Milk of goats with strong alleles associated to high αs1-casein shows higher fat and casein, longer coagulation time, firmer curds and variation in fatty acids than milk from goats with weak alleles linked to low αs1-casein. Since these milk properties are also affected by nutrition, the aim of this study was to investigate the impact of nutritional level on milk production traits of Girgentana goats with different CSN1S1 genotype. From a group of goats genotyped using PRC protocols at DNA level, 12 goats having the same genotype at αs2, β and κ- casein loci and differing for CSN1S1 genotype were selected: …

The Caciocavallo Palermitano is a typical stretched curd cheese made from cow milk, mainly in the Western Sicily. The aim of this investigation was to verify the influence of farming system and cheese making process (traditional with wood tools and natural endemic flora vs. innovative with modern stainless steel tools and selected lactic bacteria) on qualitative characteristics, including fatty acid (FA) profile, of Caciocavallo Palermitano at different ripening time. Cheeses were obtained from bulk milk from two farms: one extensive rearing a local breed fed at pasture and one intensive rearing a specialized dairy breed fed mainly hay and concentrate. Milk and cheese properties and FA prof…

Effect of β-lactoglobulin (LGB) and k-casein (CSN3) alleles on some characteristics of milk produced by Cinisara cows

2015

It is well known that β-lactoglobulin (LGB) and k-casein (CSN3) alleles affect milk cheese making properties. The purpose of this study was to analyse the A and B allele distribution at the LGB and CSN3 loci in Cinisara breed and their influence on milk and cheese making production traits. The Cinisara is a Sicilian breed which, according to DAD-IS database (FAO), consists of about 5,000 individuals and is reared mainly for milk production which is usually transformed into Caciocavallo Palermitano, a typical stretched-curd cheese. We typed 314 lactating cows at the LGB and CSN3 loci by means of RFLP-PCR analyses. The frequencies of LGB A and B alleles were 0.22 and 0.78, respectively; the f…

L’impiego alimentare di orzo germinato nella produzione di latte ovino biologico

2011

Food use of barley sprouts in organic sheep milk production. Hydroponic forage, used when fresh forage is scarce, represents a good alternative feed for milking ruminants, also in organic farming systems, where it can reduce the forage/concentrate ratio. This study evaluated the effect of barley sprouts (BS) in the diet on nutrients utilization and milk production from organic ewes. Eighteen ewes were divided into 3 groups and fed with 3 diets. Animals was fed with hay ad libitum and supplemented by: 0.6 kg/d of concentrate and 4 kg/d of BS (B100); 0.9 kg/d of concentrate and 2 kg/d of BS (B50); 1.2 kg/d of concentrate (C). Supplied and residual feeds and milk yield were recorded and sample…
