FOODS ANIMAL PRODUCTION. 77 



An attempt was also made to feed the horses on oats alone. At the 

 beginning of the trial one horse consumed 6,000 gin. and the other 

 0,750 gin. of oats per day, but after a few days refused to eat. The 

 experiment could not be continued long enough to permit the determi- 

 nation of the coefficients of digestibility. 



The author's conclusions are summarized as follows: 



" (1) Timothy hay proved to be loss digestible by horses than by ruminants. 



"(2) Grinding oats increased their digestibility. 



"(3) Corn meal was considerably more digestible than shelled corn. 



"(1) Feeding concentrated foods or grain with hay decreased the digestibility of 

 the hay. 



"(5) It is impossible to maintain horses on a grain ration alone; they must have a 

 long forage. 



"(6) Making a 'mixed feed,' of the grain and long forage is the best manner of 

 feeding horses. 



"(7) The new corn product was better digested by horses than timothy hay. 



"(8) Grinding fodder to the condition of the new corn product or of coarse bran 

 does not destroy its value as long forage." 



Several tests were made of the value of the new corn product as a 

 substitute for hay under various conditions of work. In the author's 

 opinion, those who attempt to feed this material for the tirst time should 

 gradually accustom the horses to it before substituting it entirely for 

 hay. He believes it may be successfully used as a hay substitute. 



Poultry experiments, J. Dryden ( Utah iSta. Bui. 51, pp. 33, pis. 4). — 

 In the winter of 1890-97 feeding tests were made with nine lots of 

 chickens t<> test the influence of age, breed, and exercise on the amount 

 and cost of egg production. In addition, the relative fertility of eggs 

 under different treatments and the relative value of two incubators 

 was also tested. 



Lots 1 to 8, inclusive, were made up of 1 chickens each, and lot 9 of 

 5 chickens. Lots 1 to were Rose-Comb Leghorns, lot 7 Brahma- 

 Leghorn pullets, lot 8 Light Brahma pullets, and lot 9 Barred Plymouth 

 Rock pullets. Lots 1 and 5 were old hens, lots 2 and late hatched 

 pullets, and lots 3 and 4 early hatched pullets. Lots 1 to '.) had no 

 exercise; they were fed grain from boxes. Lots 4 to 9 had exercise, 

 the grain fed being scattered in straw litter. In other respects all the 

 lots were treated alike. The food consisted of a mash of bran and 

 shorts, chopped corn, and oats, 2:1:1, fed in the morning with a little 

 whole grain (a mixture of wheat, corn, oats, and barley). The corn 

 was fed sparingly and the barley was discontinued after a short time, 

 since it was not relished by the chickens. In the evening whole grain 

 only was fed. The chickens were usually given cut meat and bones 

 three times a week, and were supplied with cabbage or other green 

 food. Occasionally they were given a little cayenne pepper during the 

 winter, and they had access to coal ashes and gravel.
