Valorization of indigenous dairy cattle breed through salami production
2016
The aim of the research was to produce salami manufactured with meat of three different commercial categories of bovine breed: cow on retirement, beef and young bull. A total of six experimental productions, at small-scale plant, were carried out with and without starter culture inoculums. The evolution of physico-chemical parameters in all trials followed the trend already registered for other fermented meat products. Several LAB species were found during process with different levels of species diversity and frequency of isolation among inoculated (mainly Pediococcus pentosaceus and Staphylococcus xylosus) and uninoculated (mainly Enterococcus devriesei, Lactobacillus curvatus and Lactoba…
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 (…
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 a GH polymorphism on milk production traits in Modicana and Cinisara cows reared in different feeding systems.
2019
Growth hormone, a polypeptide encoded by the GH gene, is a member of the somatotropin/prolactin family of hormones, which plays an important role on milk production and metabolism. In bovine, a single nucleotide polymorphism (SNP) in exon 5 changes leucine to valine (CTG to GTG) in the mature GH molecule. The purpose of this study was to evaluate, in Modicana and Cinisara cows, the effects of genetic polymorphism at GH locus and its interaction with feeding system on milk traits. A total of 97 individual Modicana blood samples were collected, 65 from a semi extensive and 32 from an extensive farm. A total of 58 Cinisara individual milk samples were collected, 32 from 7 extensive farms and 2…
Genome wide Copy Number Variation (CNV) detection in Cinisara cattle breed
2017
Copy Number Variations (CNVs) are classes of polymorphic genomic regions including deletions, duplications and insertions of DNA fragments from at least 0.5 kb up to several Mb. CNV represents an important source of genetic variability that provides genomics structural information complementary to the single nucleotide polymorphism (SNP) data. Some CNVs have been shown to be important in both normal phenotypic variability and disease susceptibility in livestock. Several approaches to identify CNVs including FISH, aCGH, SNP array or NGS, were proposed and among these SNP genotyping is relatively low cost, high-throughput and high coverage method. The aim of this study was to identify the CNV…
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…
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…
The production of typical cured meats from cattle of Cinisara breed
2019
In recent years consumers prefer genuine, tasty, protein-rich, low in fat and cholesterol products. The Cinisara cow is a dairy Sicilian autochthonous breed, reared in the western part of the isle according to the traditional livestock system, based on grazing natural pastures. The meat of Cinisara cattle could be used to obtain also processed products, among which salami and bresaola, as commercial alternatives to fresh meat, in order to increase the economic profitability of farms. The aim of this research was to produce bresaola and salami with meat from adult cows (AC) and grazing (GB) or housed (HB) young bulls of Cinisara breed, evaluating their physico-chemical and sensory traits. In…
Effect of CSN1S1 G allele on some characteristics of milk produced by Cinisara cows
2017
In bovine milk about 37-40% of total casein is represented by s1-casein. The CSN1S1 G allele is characterised by a less efficient protein synthesis (about 40%) compared with the other known alleles because of the insertion, in the 19th exon, of a Long Interspersed Nuclear Element relict responsible for a reduced mRNA stability. The lower proportion of s1-casein in milk is associated with faster formation, higher firmness and greater resistance to compression of the curd. The purpose of this study was to analyse the G allele distribution at the CSN1S1 locus in Cinisara breed and its influence on some milk traits. The Cinisara is a small Sicilian breed for which, recently, recovery and safe…
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…
