The effect of the stearoyl-CoA desaturase (SCD) gene on milk fatty acid composition was tested. Cows of 3 breeds of northern Italy, Piedmontese, Valdostana, and Jersey, were genotyped at exon 5 of the SCD gene. This has been suggested as a primary candidate gene to change the proportion of saturated vs. unsaturated fatty acids in milk, wherein a single(More)
Italy counts several sheep breeds, arisen over centuries as a consequence of ancient and recent genetic and demographic events. To finely reconstruct genetic structure and relationships between Italian sheep, 496 subjects from 19 breeds were typed at 50K single nucleotide polymorphism loci. A subset of foreign breeds from the Sheep HapMap dataset was also(More)
One hundred twenty animals of three native Italian cattle breeds, Piedmontese, Maremmana, and Podolica, were genetically characterized at 21 microsatellite loci located on 13 chromosomes. Allele numbers ranged from 3 to 19; average gene diversity ranged from 0.206 to 0.878 (average 0.738). The breed that preserved the highest genetic variability was the(More)
To set up routine assays for molecular meat traceability along the food chain, the availability of a simple and low cost test for the identification of cattle carcasses is required. For this purpose, we evaluated 13 microsatellites for their ability in the identification of animals belonging to four Italian cattle breeds. Here we propose a criterion for a(More)
In this work, the genetic variation of milk FA was investigated in three different bovine breeds, the Jersey, the Piedmontese and the Valdostana, and at different lactation stages. All animals were genotyped for 21 Single Nucleotide Polymorphisms located within nine candidate genes involved in lipid synthesis: diacylglycerol acyltransferase 1 and 2 (DGAT1,(More)
Three novel SNPs were identified in the locus OAR292286, encoding the DNA sequence of promoter III of the ovine acetyl-CoA carboxylase-alpha gene, in Italian sheep of four breeds: Gentile di Puglia (25 individuals) and Sopravissana (31) which are triple-purpose local endangered breeds, Comisana (25) which is a local non-selected, non-endangered dairy breed(More)
Two traits were compared as breeding objectives for the selection of dairy sheep: the total milk produced during 1 yr and the production over the first 70 d in milk. Both traits are proposed for sheep breeds that have more than one lambing per year and, consequently, highly variable lactation length. Breeding values for both traits were obtained with an(More)
The aim of this study was to investigate the effect of Montbéliarde (Mb) gene frequency on fatty acid composition and sensory properties of Italian Simmental (IS) steaks (longissimus thoracis m.). Twenty-seven bulls belonging to three strains with different percentages of Mb genes: traditional (ISt), without Mb ascendants (ISt=0% Mb genes), cross-strain(More)
