Cattle feeding.— XI, Winter steer feeding, 1914-15, J. H. Skinneb and 

 F. G. King (Indiana Sta. Bui. 183 {1915), pp. 851-891, fig. 1; pop. ed., pp. 8, 

 fig. i).— In these experiments seven lots of 10 steers each were fed 150 days, 

 all the lots except lots 1 and 6 receiving shelled corn and 2.5 lbs. daily per 1,000 

 lbs. live weight of cotton-seed meal, and lot 1 receiving shelled corn, ground soy 

 beans, 2.5 lbs. daily per 1,000 lbs. live weight, corn silage and oat straw; 

 lot 2, clover hay; lot 3, alfalfa hay; lot 4, corn silage and clover hay; lot 5, 

 molasses, corn silage, and clover hay ; lot 6, shelled corn, molasses feed, corn 

 silage, and clover hay; and lot 7, corn silage and alfalfa hay. Ten head of 

 hogs followed each lot. The work was in continuation of that previously noted 

 (E. S. R., 33, p. 371). 



Part 1 is a comparison of corn silage and leguminous hay v. leguminous hay 

 for fattening steers, involving lots 2, 3, 4, and 7. 



" The addition of 24.94 lbs. of corn silage to a ration of shelled com, cotton- 

 seeTi meal, and clover hay decreased the average grain consumption 4.09 lbs. 

 daily per head and the hay consumption 8.6 lbs. daily per steer. The addition 

 of 28.36 lbs. of corn silage to a ration of shelled corn, cotton-seed meal, and 

 alfalfa hay decreased the average grain consumption 4.09 lbs. daily per head and 

 the hay consumption 10.23 lbs. daily per steer. The addition of corn silage to 

 a ration consisting of shelled corn, cotton-seed meal, and clover hay decreased 

 the rate of gain, while in a ration containing alfalfa hay the gains of the 

 cattle were increased by the addition of corn silage. Corn silage in the ration 

 decreased the cost of gain 4 cts. per 100 lbs. when clover hay was fed and 

 $3.16 per 100 lbs. when alfalfa hay was fed. The addition of corn silage to the 

 ration had on the average no effect on the finish of the cattle. The addition 

 of corn silage to the ration decreased the loss per steer $2.80 when clover hay 

 was fed and $12 when alfalfa hay was fed." 



Part 2 is a comparison of ground soy beans v. cotton-seed meal for fatten- 

 ing steers, involving lots 1 and 4. The cattle fed ground soy beans made the 

 more rapid and more economical gains and attained a higher finish. There 

 was a greater pork production in the lot receiving cotton-seed meal. 



Part 3 is a comparison of clover hay v. alfalfa hay as roughage for fatten- 

 ing steers, involving lots 2, 3, 4, and 7. The cattle fed shelled corn, cotton-seed 

 meal, and clover hay ate the same quantity of corn and very nearly the same 

 quantity of hay as the cattle fed shelled corn, cotton-seed meal, and alfalfa hay. 

 Cattle fed shelled corn, cotton-seed meal, clover hay, and corn silage consumed 

 the same quantity of grain but more hay and less silage than those fed a ration 

 in which alfalfa hay was used instead of clover. Cattle fed clover hay as the 

 only roughage made more rapid gain than those fed alfalfa hay. Cattle fed 

 clover hay and corn silage made less rapid gains than those fed alfalfa hay and 

 corn silage. Gains were more economical with clover hay than with alfalfa hay 

 as roughage, and less economical with clover hay and corn silage than with 

 alfalfa hay and corn silage as roughage. Cattle fed a ration of shelled corn, 

 cotton-seed meal, and clover hay returned a loss, including pork, of $10.26 

 per steer against a loss of $13.07 when alfalfa hay replaced clover hay. A 

 ration of shelled corn, cotton-seed meal, corn silage, and clover hay returned 

 a loss, including pork, of $7.46 per head as compared with a loss of $1.07 per 

 head when clover hay was replaced by alfalfa hay. 



Part 4 is a comparison of cane molasses v. mixed molasses feed as supple- 

 ments to rations for fattening cattle, and involving lots 4, 5, and 6. It was 

 found that the substitution of a small quantity of feeding molasses for an 

 equal quantity of corn in a ration of shelled corn, cotton-seed meal, clover 

 hay, and corn silage had no appreciable effect on the consumption of con-
