Constants of Cow Milk

The Madras Act has also standardized the value of proteins of the cow milk as nitrogen at 0.5 per cent and that of dirt in it at 5 per 100,000 by volume. It may be remembered here that the standards fixed in England by the Ministry of Agriculture and Fisheries by their Sale of Milk Regulation, 1901, are 3 per cent for milk and 8.5 per cent for milk solids other than milk fat. So the standard prescribed in India for the milk solids other than fat is the same as in England, except in the Punjab where it is lower and that for milk fat is higher in 6 of the provinces but the same in the remaining three, namely, Madras, Bihar and Orissa and the Central Provinces. We examined 88 samples of pure milk, each sample drawn from a single cow. Two of these samples appeared to be abnormal, the milk solids other than fat in them were 5.9 and 11.5
