Interaction between stearoyl-coenzyme A desaturase polymorphism and feeding system in affecting the fatty acid profile of sheep cheese
Stearoyl-coenzyme A desaturase (SCD) catalyses the synthesis of monounsaturated fatty acids, by introducing a cis double bond at the delta 9–10 position. The study investigated the effects of a polymorphism at the ovine SCD gene and its interaction with the inclusion of fresh forage in the diet on cheese fatty acid (FA) composition in Valle del Belice ewes. A region of 527 bp of the ovine SCD gene including the partial sequence of the promoter, the complete sequence of the 5’ UTR and exon 1 and the partial sequence of intron 1 were analyzed in order to identify the g.87C > A SNP located in the promoter region. A feeding trial was carried out using 16 Valle del Belice ewes selected on the…

Effects of a GH polymorphism on milk production traits in Modicana and Cinisara cows reared in different feeding systems.
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…
