Effects of sheep α_s1-casein CC, CD and DD genotypes on milk composition and cheesemaking properties

摘要

The effects of sheep α_s1-casein CC, CD and DD genotypes on milk composition and cheese yield were studied. Processed bulk milk was collected from three groups of 15 ewes, carrying α_s1-casein CC, CD and DD genotypes. CC milk was higher in casein content than CD or DD milk (+3.5 and +8.6/100 respectively), and had a higher protein: fat ratio and a smaller casein micelle diameter.
