TABLE SHOWING POUNDS OF CASEIN FOR ONE POUND OF ALBUMEN 3.66 4.18 4.08 3.68 4.37 Greatest... 4.50 4.02 3.60 a. For each pound of albumen in milk, the casein varied from 2.95 to 4.50 pounds and averaged 3.60 pounds during the season. b. The amount of casein relative to albumen was greater in April, decreasing in May and June, increasing in July and remaining fairly uniform. during July, August and September and then increased in October. 10. Relation of Fat to Casein in Normal Milk. TABLE SHOWING RELATION OF FAT TO CASEIN IN NORMAL MILK. TABLE SHOWING POUNDS OF FAT FOR ONE POUND OF CASEIN IN a. For each pound of casein in the milk, the fat varied from 1.38 to 1.78 lbs and averaged 1.52 lbs. during the season. b. There is a remarkably close correspondence between these results and those secured in the Stone and Merry factories. We notice the same uniformity during April, May, June and July and the increase of fat relative to casein during August and then the slight diminution in September and finally the normal condition in October. The same causes, dry pastures and probable semi starvation in July and August, produced an abnormal condition from which the cows did not recover before October and even then the recovery extended only to the composition of the milk. Relation of Fat and Casein in Milk of Different Herds of Cows. In the following table we give the results secured in analyzing the milk from two separate herds in each factory where work was done; one representing milk rich in fat and the other, milk poor in fat. One difficulty connected with this method, is that the poor milk is very often apt to be skimmed while the object is to compare only normal milk. In the table below the skimmed milks are marked and are excluded from the averages. |
