casein meal ration 32.74, vegetable-dried-blood meal ration 26.85, home mixed 

 meal ration 26.17, and vegetable meal ration 26.14. The nitrogen intalie was 

 rather constant per kilogi-am of body weight, the maximum difference being 

 12 per cent. It appeared that when the nitrogen in the ration was the most 

 suitable for growth the nitrogen excreted was about equally divided between 

 the feces and the urine. 



Sheep feeding. — VI, Fattening western lambs, 1915-16, J. H. Skinner 

 and F. G. King {Indiana Sta. Bui. 192 (1916), pp. 20; pop. ed., pp. 7).— In these 

 experiments, which are in continuation of those already noted (E. S. R., 35, 

 p. 476), nine lots of 25 lambs each were fed for 100 days, eight of the lots being 

 fed in open sheds and one lot in the barn. The lambs were choice improved 

 Mexicans of excellent quality. The rations fed, in addition to shelled corn, 

 and some of the results obtained are given in the following table :

In a comparison of corn silage v. corn silage and clover hay for fattening 

 lambs, involving lots 3 and 6, it was found that the addition of silage to a 

 ration of shelled corn and clover hay had no effect on the grain consumption, but 

 that 112 lbs. of silage replaced 65 pounds of clover hay in roughage consumption. 

 Comparing corn silage alone v. corn silage and dry roughage, involving lots 1, 5, 

 and 7, it was found that with tlie elimination of dry roughage from the ration 

 there was a decrease in grain consumption and an increase in silage consump- 

 tion. When oat straw was fed in connection with silage more corn was re- 

 quired to produce a pound of gain than when either silage alone or silage and 

 clover hay were fed. 



In a comparison of clover hay and alfalfa hay, involving lots 3 and 4, the hay 

 consumption was higher when clover was fed, and the finish on the lambs better 

 when alfalfa was fed. In this test the clover hay was slightly moldy and the 

 alfalfa hay of excellent quality. The addition of cottonseed meal at the rate 

 of 3 lbs. per day for 25 lambs to a ration of shelled corn, clover hay, and corn 

 silage, involving lots 6 and 7, had no effect on the daily feed consumption, but 

 apparently gave a much better finish to the lambs. In substituting a small quan- 

 tity of cane molasses for an equal quantity of corn in a ration of shelled corn, 

 cottonseed meal, clover hay, and silage, involving lots 2 and 7, no marlied effects 

 on the appetites or finish of the lambs were noted.
