Influence of Somatic Cell Count on Ewe’s Milk Composition, Cheese Yield and Cheese Quality
Milk samples with low (<500,000/ml), medium (500,000-1,000,000/ml) and high (1,000,000-2,000,000/ml) Somatic Cell Counts (SCC) were obtained from a flock of 120 Sarda breed ewes. Milk was analysed for chemical composition and rheological properties (Formagraph), and used for a laboratory scale cheesemaking. The milk of the three groups showed differences (P<0.01) in pH, lactose, whey protein an...
متن کاملVariation in blood leucocytes, somatic cell count, yield and composition of milk of crossbred goats
Ten multiparous crossbred goats, ®ve each of alpine beetal (AB) and saanen beetal (SB) were selected from the National Dairy Research Institute goat herd immediately after parturition. These were managed as per the practices followed in the institute's goatherd. Blood and milk samples were collected at biweekly intervals from day 14 post-kidding for 22 weeks (154 days). Somatic cell count, elec...

متن کاملEffect of parity on milk yield, composition, somatic cell count, renneting parameters and bacteria counts of Comisana ewes.
Twenty-four Comisana ewes, with no history of mastitis, were included in this study, with eight ewes each in parities 1, 2 and 3. Groups were separately penned on straw litter and ewes were individually checked for yield, composition, renneting properties and bacteriological characteristics of milk from January, when separated from their lambs (50+/-3 days after lambing), to May. Samples with m...
متن کاملGenetic Trends for Milk Yield, Persistency of Milk Yield,Somatic Cell Count and Calving Interval in Holstein Dairy Cows of Iran
The objective of the present study was to estimate genetic trends for lactation milk yield, persistency of milk yield, somatic cell count and interval between first and second calving in Holstein dairy cows of Iran. The dataset consisted of 210,625 test day and 25,883 first parity cows with milk yield recorded from July 2002 to September 2007 comprising 97 herds in Iran. Breeding values of anim...
