Intake and milk production of goats grazing Sulla forage under different stocking rates
This investigation aimed to individuate the dietary factors affecting the milk urea nitrogen (MUN) concentration in goats grazing herbaceous pasture and, particularly, to verify the relationship linking the diet crude protein (CP) content to MUN. A total of 205 individual observations regarding dietary and milk variables of 37 Girgentana goats involved in two experiments were used. Goats, averaging 154±14 days in milk and 38.1±5.4 kg of live weight, grazed on swards and received 500 g/d of barley meal. Sward biomass, herbage selected by goats and individual milk yield were measured and sampled weekly. The herbage intake and diet digestibility were estimated by the n-alkane method. Milk urea…
Effects of mountain grassland maturity stage and grazing management on carotenoids in sward and cow's milk
Carotenoids are involved in the sensorial and nutritional values of dairy products. In grazing systems, both herbage maturity stage and grazing management may affect the amount of carotenoid ingested, thus these factors may affect carotenoid concentrations in milk. Two homogenous plots of mountain grassland (1.4 and 2.0 ha) were grazed during two cycles of growth by 6 dairy cows in mid lactation, in strip (SG) and rotational grazing (RG), respectively. We monitored the changes in carotenoid concentrations in sward and milk, measured by HPLC twice a week. Seven carotenoids were identified in the sward: violaxanthin, antheraxanthin, epilutein, lutein, zeaxanthin, ß-carotene and 13-cis ß-carot…

Comparing quality characteristics of “Caciocavallo Palermitano” cheese from traditional and intensive production systems
The “Caciocavallo Palermitano” is a typical stretched curd (pasta filata) cheese, made mainly in the Palermo area, in the Western Sicily, from cow milk. The aim of this investigation was to verify the influence of the on-farm production system (traditional vs. intensive) on some qualitative characteristics of “Caciocavallo Palermitano” cheese, with particular regard to fatty acid (FA) profile. On June 2008, 1-month aged cheeses were sampled from 6 traditional farms (TRD) and 5 intensive farms (INT). In TRD farms, local cow breeds (Cinisara, Modicana or Siciliana) were fed pasture-based diet and cheeses were manufactured using artisanal wood tools by following the traditional technique. The …
Effects of continuous and rotational grazing of different forage species on ewe milk production
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…

Energy intake effects at pasture on milk production and coagulation properties in girgentana goats with different as1-cn genotypes
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…
Effect of diet and CSN1S1 genotype on nutritional, productive and metabolic responses of milking Girgentana goats
Effects of feeding green forage of sulla (Hedysarum coronarium L.) on lamb growth and carcass and meat quality.
The nutritional effects of sulla (Hedysarum coronarium L.) forage containing condensed tannins (CT) on growth of lambs, and carcass and meat quality were investigated. Thirty-two male Comisana lambs aged 100 ± 8 days weighing 19.0 ± 2.8 kg were fed fresh forage of sulla or CT-free annual ryegrass (Lolium multiflorum Lam. subsp. Wersterwoldicum) for 49 days until slaughter; in addition, each lamb was supplied with 200 g/days of concentrate. Eight lambs per diet had been previously treated with anthelmintic drugs to remove nematode parasites. Measurements of BW and feed intake, and counts of faecal nematode eggs were made. Carcass parameters were recorded after slaughter, and tissue component…

Endocrine and ovarian response after a 2-day controlled suckling and eCG treatment in lactating rabbit does.
Synchronization methods are used to obtain higher fertility when artificial insemination (AI) is applied to lactating rabbit does. The most common methods are eCG administration or temporary doe–litter separation. Nevertheless, drawbacks have been reported, such as negative side effects of hormonal treatment in the doe and low litter growth due to absence of suckling, respectively. Recently, improved reproductive performance (without visible consequences on young rabbit growth), has been obtained by applying a 2-day controlled nursing method before AI, by allowing for a 10 min nursing of the litter 24 h of separation. The present study was undertaken to examine the pituitary (PRL, LH, FSH) …
Influence of fresh forage-based diets and αS1-casein (CSN1S1) genotype on nutrient intake and productive, metabolic, and hormonal responses in milking goats
Abstract Polymorphism at the α S1 -casein locus ( CSN1S1 ) in goats influences several milk production traits. Milk from goats carrying strong alleles, which are associated with high α S1 -casein (α S1 -CN) synthesis, has higher fat and casein contents, longer coagulation time and higher curd firmness than milk from goats with weak alleles linked to low α S1 -CN content. Nutrition also affects these milk properties; therefore, it is important to better understand the interaction between dietary characteristics and the CSN1S1 genotype in goats. This study aimed to investigate the effect of fresh forage based diet or energy supplement on feeding behavior, milk production, and metabolic and ho…

Transfer of milk fatty acids to Pecorino Siciliano cheese
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…

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

Changes in Terpene Content in Milk from Pasture-Fed Cows
Changes of terpene content in milk from cows grazing natural diversified upland pasture were examined in this observational trial. A homogeneous plot divided into 2 subplots was used from May 31 to July 1, 2003 (first growth) and again from October 1 to October 7, 2003 (vegetative regrowth). Each subplot was grazed by 6 dairy cows in 2 ways: strip grazing (SG), with new allocations of pasture strips at 2-d intervals, and paddock grazing (PG). The PG subplot was divided into 3 paddocks and the cows were moved to a new paddock on June 13 and June 24, 2003. Milk from the 6 cows was collected twice a week, pooled, and used for terpene analyses by dynamic headspace gas chromatography-mass spectr…

Addition of pasture plant essential oil in milk: Influence on chemical and sensory properties of milk and cheese
The aim of this experiment was to study the effect of the addition, to milk, of an essential oil (EO) obtained from the hydrodistillation of plants collected from a mountain natural pasture on the milk and cheese sensory properties. The EO was mainly composed of terpenoid compounds (67 of the 95 compounds identified) as well as ketones, aldehydes, alcohols, esters, alkanes, and benzenic compounds. In milk, the addition of this EO at the concentration of 0.1 microL/L did not influence its sensory properties, whereas at 1.0 microL/L, sensory properties were modified. In cheeses, the effect of adding EO into milk was studied in an experimental dairy plant allowing the production of small Canta…

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

Persistence of wild Streptococcus thermophilus strains on wooden vat and during the manufacture of a traditional Caciocavallo type cheese
The present work was undertaken to evaluate the influence of the wooden dairy plant equipment on the microbiological characteristics of curd to be transformed into Caciocavallo Palermitano cheese. Traditional raw milk productions were performed concomitantly with standard cheese making trials carried out in stainless steel vat inoculated with a commercial starter. Milk from two different farms (A and B) was separately processed. The wooden vat was found to be a reservoir of lactic acid bacteria (LAB), while unwanted (spoilage and/or pathogenic) microorganisms were not hosted or were present at very low levels. All microbial groups were numerically different in bulk milks, showing higher lev…

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