' Cost of additional feed consumed by hogs deducted. 



Feed costs and profits in these experiments were based upon the following 

 figures : Initial value of steers 6.9 cts. per pound ; pork 9.75 cts. per pound ; 

 corn 55.9, 62.5, 62.4. 58.2, and 63.7 cts. per bushel from the first to the fifth 

 months, respectively ; and cottonseed meal $38, molasses feed $31, cane molasses 

 $30, clover hay and alfalfa hay $12, and corn silage $4.50 per ton. 



Skim milk and milk substitutes for calf feeding, O. F. Hunziker and R. E. 

 Caldwell (Indiayui Sta. Bui. 19S (1916), pp. 3-104, figs. 31).— In these experi- 

 ments three lots of 10 calves each, for the most part pure-bred Jerseys, 

 Holsteins, and Ayrshires, were fed for 182 days. Individual photographs taken 

 under standard conditions to show the physical condition and variations in 

 size, representing six 30-day periods in the first six months in each calf's life, 

 are reproduced together with a tabulated average daily summary of the feeds 

 consumed, composition and cost of ration, and variations in live weight for each 

 of the 26 weeks of the experiment. 



All the calves remained with their dams until four or five days of age, at 

 which time they were placed on bucket feeding. The calves in lot 1 were fed 

 whole milk until they were three weeks old, the whole milk being gradually 

 replaced by skim milk during the second and third weeks after which a full 

 ration of skim milk was fed in most instances until six months old. In addi- 

 tion to skim milk they had a dry mash of ground corn and oats, equal parts 

 by weight, choice alfalfa hay, and a small amount of corn silage, the grain, 

 hay, and silage being placed before them at ten days of age. 



The calves in lot 2 were fed whole milk until five weeks of age, this being 

 gradually replaced (beginning at seven days of age) by a home-mixed calf meal 

 (containing hominy feed, linseed meal, red dog flour, and dried blood, equal 

 parts by weight) mixed with water in the proportion of 1:7. Whole milk was 

 fed to the calves that developed digestive disturbances or were otherwise off 

 feed until the eleventh week. By the time the regular feeding of whole milk 

 was discontinued the calves were getting from 18 to 20 oz. of the mixed meal 

 per head daily, which amount was increa.sed to 24 oz. by the time they were 

 six months old. Otherv^^ise this lot had the same feeds as lot 1. 



Lot 3 received whole milk regularly until five weeks of age, this being grad- 

 ually replaced by a proprietary calf meal beginning during the .second week, 

 the calf meal being gradually increased and mixed with water in accordance 

 Avith directions of the manufacturers until they were receiving a full ration 

 of 17 oz. per head daily at five weeks. This amount was increased to 22 ozt.
