derived from pasture. The pastured steers of one group were In pasture 140 

 days and gained an average of 125 lbs. per head. During the time they were 

 on stall feed the average cost was $61.70. They sold for 7.75 cts. per pound, 

 while the lot on continuous stall-feeding cost $81.07 per head and sold for 8.25 

 cts. per pound. The pastured steers brought $23.16 net per head, and the stall- 

 fed steers $9.38, so that the pasture saved 68.9 cts. per week on feed cost of pro- 

 duction. The steers of the other group were in pasture 153 days and gained an 

 average of 44.4 lbs. per head. The stall-fed steers brought an average of $19.36 

 net per head, and the pastured steers $26.26. Even under the small gain made 

 they saved 31.4 cts. per week per head on feed cost of production. 



[Animal husbandry] (Nebraska Sta. Rpt. 1915, pp. X, XI, XV, XVI). — 

 In an experiment in pig feeding, carried on to determine the relative value** 

 of tankage and alfalfa hay in supplying protein to a ration in which ear corn 

 and shelled corn were used, the results showed that the cheapest gains were 

 made on a ration of ear corn and alfalfa hay. The addition of tankage to 

 a ration of shelled corn and alfalfa increased the rate of gain and lowered the 

 cost of gain when compared with shelled corn and alfalfa hay. However, this 

 cost was higher than the cost of gains made with ear corn and alfalfa hay. 



Seven lots of lambs were fed 90 days as follows : Lot 1, com and oil meal on 

 grass pasture ; lot 3, corn, alfalfa hay, and silage ; lot 4, corn, alfalfa hay, rape 

 pasture, and turnips ; and lot 6, com and alfalfa hay in a dry lot ; lots 2, 5, and 

 7 running in a cornfield and receiving in addition cotton-seed cake and alfalfa 

 hay, alfalfa hay, and oil meal and alfalfa hay, respectively, after frost. The 

 gains made varied from 0.18 to 0.27 lb. per day. The net profits for the lots 1 

 to 7 were $1.22 and 97, 91, 87, 68, 68, and 66 cts., respectively. In this experiment 

 the lambs upon grass pasture with corn and oil meal made materially better 

 gains than any other lot. The lot running in a cornfield receiving alfalfa hay 

 after frost did not make as favorable gains as could normally be expected, owing 

 to disturbances while the feeding experiment was in progress. 



Experiments in pork production at the North Platte substation indicate that 

 stewing or cooking alfalfa has increased the rate of gain slightly and slightly 

 decreased the food eaten per pound of gain. However, the cost of stewing the 

 alfalfa probably was greater than the advantages gained. The proportions of 

 corn, tankage, and alfalfa hay eaten from self-feeders by fall shotes during the 

 winter, where skim milk formed a part of the ration, were corn 85.1, alfalfa hay 

 8.1, and tankage 6.8. The food consumed per pound of gain was corn 2.915 lbs., 

 alfalfa hay 0.278, tankage 0.235, and skim milk 2.58 lbs. 



Three lots of lambs were fed during a winter as follows : Lot 1, corn and 

 alfalfa ; lot 2, corn, alfalfa, and cotton-seed cake ; and lot 3, corn, corn silage, 

 and alfalfa. The lot fed silage made a trifle larger gain, about 2.5 lbs. per 

 head per week. The lambs fed cotton-seed cake gave a little more profit than 

 those fed either of the other two rations, but probably not sufficiently greater to 

 warrant the feeding of cotton-seed cake when the price is much above $30 per 

 ton. Silage at $4 per ton was so expensive that the ration containing it pro- 

 duced less profit than either of the other two rations. The cost per pound of 

 gain on a ration of com and alfalfa hay was 5.7 cts. 



Hogging down soy beans and cowpeas, E. S. Good and M. J. Smith (Ken- 

 tucky Sta. Bui. 201 (1916), pp. 139-1^, figs. 2).— Three lots of 90-lb. pigs were 

 fed as follows : Lot 1, hogging down soy beans plus corn meal equal to 2 per 

 cent of their body weight ; lot 2, hogging down soy beans without corn ; and lot 

 3, hogging down cowpeas and corn meal equal to 2 per cent of their body 

 weight. The average daily gains made were 1.3, 0.261, and 0.303 lbs. per pig, 

 and the cost per pound of gain, including cost of seed sown, plowing and cul- 

 tivation, rent of land, labor involved in feeding, and corn consumed, was
