Studies on variance of the composition of milk



Studies on variance of the composition of milk



J. Fac. Agric. Hokkaido Univ 53(2): 228-47



Milk samples from individual cows in 4 herds were taken from May 1961 to April 1962 (a.m. milk) and from May 1962-Oct. 1962 (p.m. milk), and the average composition was found to be as follows: T.S., 11.54%; fat, 3.52%; protein, 3.14%; lactose, 4.08%; ash, 0.70%. The average yield/cow/day was 12.73 kg. There was a significant difference between the T.S. content of a.m. and p.m. samples, and between T.S., S.N.F., fat and protein contents in the different herds.
