Abstract: The aim of the study was to estimate the effect of the composite CSN2 and CSN3 genotypes on milk coagulation, quality, and yield traits in Italian Holstein cows. A total of 1,042 multiparous Holstein cows reared on 34 commercial dairy herds were sampled once, concurrently with monthly herd milk recording. The data included the following traits: milk coagulation time; curd firmness; pH and titratable acidity; fat, protein, and casein contents; somatic cell score; and daily milk, fat, and protein yields. A singl… Show more

“…Unfortunately, they did not identify CSN3 allele E in their study. On the contrary, Comin et al (2006) reported that the genotypes containing CSN3 allele E were associated with poor coagulating milk, and genotypes with CSN3 allele B resulted in the best coagulation properties of milk.…”

“…Genotype BEAA was identified only in a single cow. The low frequency of allele E is beneficial because this allele has a negative effect on milk coagulation properties (Ikonen et al, 1999a;Comin et al, 2006).…”

“…Improvement of these traits can be achieved through selection for correlated traits such as milk protein content and composition (Bonfatti et al, 2011;Jensen et al, 2012), milk acidity (Ló pez et al, 1998; -E-mail: martino.cassandro@unipd.it Ná jera et al, 2003) and somatic cell count (SCC; Politis and Ng-Kwai-Hang, 1988;Klei et al, 1998). Moreover, genetic variants at the protein loci have been demonstrated to exert an effect on MCP (Kü barsepp et al, 2005;Comin et al, 2008). In addition, the possibility of improving MCP through selective breeding has been demonstrated in several studies, involving different dairy cattle populations in different countries.…”
