4:1 cost 5.37 cts., which under most conditions is considered reasonable. The 

 feeding of rye alone i^roved unsatisfactory. 



In 1911, 4 lots of 8 head each of approximately 116-lb. pigs were fed during 

 a period of 8 weeks with the following costs of gain per pound : Corn and shorts 

 1 : 1, 5.72 cts. ; com and alfalfa meal 4 : 1, 4.84 cts. ; corn and alfalfa meal 5 : 1, 

 5.35 cts. ; and com and alfalfa meal 6 : 1, 5.0S cts. 



During the 2 years feeding at the station no ill effects upon hogs was caused 

 by fertilizer tankage, which was obtained at a much lower price. It is stated, 

 however, that " while feeders, particularly those operating on a large scale, 

 may save considerable money by the use of fertilizer tankage, they should make 

 sure of the process of preparation of the product before using it." 



Plans for industrial hog houses, alfalfa feeding racks, and feeding troughs are 

 included. 



Pig'-feeding' experiment, C. Hutchinson {Jour. Southeast. Agr. Col. Wye, 

 1912, No. 21, pp. 29-43). — Tests were made "to determine the value of gram 

 as a substitute for separated milk in combination with middlings in the feed- 

 ing of uewly-weaned pigs intended for sale as porkers." 



It is concluded that " 0.5 lb. per day of gram meal to newly-weaned pigs is a 

 perfectly safe food. In combination with middlings it constitutes a good and 

 economic ration, which can confidently be recommended where separated milk 

 is not available." 



Feeding work horses, C. W. McCampbeill {Kansas Sta. Bui. 186, pp. 13-70, 

 figs. 14). — A portion of this work has been previously reported from another 

 source (E. S. R., 27, p. 772). 



It was found that the substitution of corn, bran, and linseed meal 6:3:1 for 

 oats in a ration for work horses proved quite satisfactory, although the gains 

 in weight were not so great. Two rations consisting of com and oats 1 : 1, but 

 differing in that one had also 4 lbs. of bran, the other 1 lb. of old process linseed 

 meal, showed practically no difference in results aside from a sleeker coat of 

 hair with the linseed-meal-fed horses. It was found that pound for pound, 

 oats and barley are practically equal as feed for horses, although the oats are 

 to be preferred due to their superior effect upon the general condition of the 

 animal. The substitution of i lb. of brown sugar for 2 lbs. of oats in the 

 ration proved to be impracticable, although a small amount of sugar is recog- 

 nized as an excellent appetizer. The sugar-fed horses sweated more easily and 

 more profusely but showed excellent coats of hair and good appetites. 



Comparing alfalfa meal and bran it was found that these feeds are practically 

 equal pound for pound, and that alfalfa meal lessens the daily cost about 1 ct. 

 per 1,0(X) lbs. live weight. However, the alfalfa meal is in disfavor due to its 

 dust and irritation to the mucous membranes. Furthermore, the danger of 

 adulteration and use of poor hay is suggested. Alfalfa hay, corn, and oats, as 

 compared with oats and prairie hay, proved cheaper and produced greater gains. 

 Four lbs. of alfalfa meal, substituted for 2 lbs. of corn and 2 lbs. prairie hay, 

 resulted in no reduction in cost. It is estimated that 1 lb. of alfalfa hay is 

 equal to 2 lbs. of prairie or timothy hay. It reduced the amount of hay fed 

 30 per cent and the amount of grain 16 per cent; the cost was less and the 

 gains were greatei*. Timothy hay proved to be slightly superior to prairie hay 

 as a feed for work horses. 



The feed and care of stallions, brood mares, foals, and growing horses are 

 discussed, and rations suggested.
