Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913 edition. Excerpt: ...milk. The nutritive ratio of the various grades of miik ranges from 1:4.23 for milk testing 3 per cent fat to 1:4.88 for milk testing 7 per cent fat. The last column shows the relation of fat to solids-not-fat. In 3-per-cent milk there are 2.43 pounds of solids-not-fat to 1 pound of butter fat; and in 6-per-cent milk, 1 pound of fat to 1.45 pounds not fat, indicating that butter fat only is not a logical basis for feeding for milk-production. From a study of the table it appears that there is a slight depression in the protein content of milk testing 3.5 per cent butter fat, and also that there is an abnormal rise in the protein content of milk averaging 6.5 per cent butter fat. It appears that it should be 4.02 instead of 4.12. This is also indicated by the nutritive ratio. The samples of milk taken from cows while on low-protein rations are not included in Table 31, giving the organic composition of milk and relation of the solids, because of the depression of milk solids as shown by Table 32. TABLE 32 Average Composition Cf Milk Produced By Cows When On A Low-protein Ration And When On A Medium-protein Ration It is shown that without exception the cows-gave milk containing a lower percentage of solids when fed a ration containing a nutritive ratio of 1:9.4 than they did when receiving.rations ranging in nutritive ratio from 1: 6 to 1: 8.3 and when on pasture. There was also a depression in both fat and protein in every case. Taking the total solids as a basis the fat is lowered 1.2 per cent and the protein 1.3 per cent and the milk sugar or carbohydrate raised 2.2 and the ash raised 0.3 per cent, thus offsetting the depression in fat and protein.
