Substitutes for Skimmed Milk in Raising Calves 31 



(6) Lactina Suisse gave results comparable with Blatchford's Calf 

 Meal. It is too expensive to feed and the results from it were too poor 

 to warrant its use when any other food can be obtained. 



(7) A tablespoonful of soluble blood meal mixed with each feed served 

 to keep the bowels of the calves in better condition, and since it is com- 

 paratively inexpensive a wider use of it might be profitable. 



By comparing the photographs of the calves in the different groups 

 (Figs. I, 3, 5, 7, 9, II, and 13), a fairly good idea can be had of the 

 kind of calves produced with the different foods. 



III. SUPPLEMENT SHOWING DEVELOPMENT OF CALVES AS TWO-YEAR-OLDS 



AND THREE-YEAR-OLDS 



As a supplement to the foregoing, pictures are given of the arimals 

 now in the college herd that were under experiment as calves. The piu-- 

 pose of these pictures is to show that, as two-year-olds and three-year- 

 olds, there is apparently no less constitutional vigor manifested by the 

 animals that were in poorer condition at five months of age, due to feeding 

 them substitutes for skimmed milk, than by the animals which received 

 skimmed milk and which were in better condition at that age. 



1. Animals fed as calves in 1907-1908. — Comparing Figs, i, 3, and 

 5, we see that, as calves, those animals fed skimmed milk were decidedly 

 the best in appearance, those fed Schumacher Calf Meal were next, and 

 those fed Lactina Suisse were the poorest. This fact is further empha- 

 sized in comparing the average daily gains in Table VII. Lot A, fed 

 skimmed milk, made an average daily gain of 1.76 pounds; Lot B, fed 

 Schumacher Calf Meal, 1.25 pounds; Lot C, fed Lactina Suisse, .70 

 pounds. 



The heifers now in the herd from Lot C, calves Nos. 18 and 20, shown 

 in Fig. 6 as three-year-olds, developed into as good heifers as any in the 

 herd raised from calves in 1907-8, notwithstanding their poor start on 

 Lactina Suisse. They are as fine in appearance as any in Lots A or B, 

 and seem to have as much constitutional vigor; and in their production 

 during their first lactation period they have excelled all of the heifers from 

 Lots A and B. The three heifers shown in Fig. 4, which were calves 

 Nos. 8, 9, and 10 of Lot B, fed Schumacher Calf Meal, are the equal in 

 constitutional vigor and appearance of the heifers raised from Lot A, as 

 shown in Fig. 2. 



2. Animals fed as calves in 1908-1909. — The same general condition is 

 found on comparing the pictures of the two-year-old heifers raised as 

 calves in 1908-9 as was found for the calves raised in 1907-8. The
