" In this test while the steers fed the larger grain ration gained more and 

 taster than those fed the smaller grain ration, yet the gains were in no wise in 

 proportion to the difference in the grain." 



Feeding range steers, J. J. Vernon (Netc Mexico Sta. Rpt. 190-'f, pp. 27, 

 2,S)._The valne for winter feeding of alfalfa hay alone and supplemented by 

 a light grain ration of bran and cracked wheat 1 : 8 was tested with 2 uniform 

 lots of 5 2-year-old range steers each. On alfalfa and grain the net profit was 

 calculated to he $7.42 per ton of hay and on the hay alone .$S.4(l. 



The quantity of milk taken by nursing calves and its fat content, T. 

 Henkel and E. Muhlbach {Lamlw. Vers. Stat., 63 {1906), No. 5-6, pp. JtOl- 

 Ji69, figs. 12). — It was found in the experiments reported on methods to be fol- 

 lowed with nursing calves that the best results were obtained when the calf 

 nursed at frequent and regular intervals. If the calf nurses before the cow has 

 been milked at all, it obtains milk of low fat content. If, however, the cow has 

 been milked somewhat, the calf obtains milk rich in fat. The effect of different 

 methods of milking iind other related questions are also considered. 



Sheep feeding experiments for the years 1904-5, F. B. Linfield {Montana 

 Stu. Bill. 59. pp. sr>-116).—-ln the lirst of the feeding tests the comparative 

 value of wheat screenings, wheat, oats, barley, and a mixture of eciual parts of 

 wheat, oats, and barley, was tested with 5 lots of lambs and 5 lots of wethers, 

 each lot containing 24 animals. The grain ration in every case was supple- 

 mented by clover hay. 



During the whole period of the test, 97 days, the greatest gain of the wethers. 

 0.219 lb. per head per day, was noted with the lot fed wheat, and the smallest 

 gain, 0.187 lb., with the lot fed the mixed grain. The cost of a pound of gain 

 was lowest, 7.49 cts., on wheat screenings, and greatest, 8.73 cts., on mixed 

 grain. With lambs the greatest gain, 0.25G lb., was noted on wheat screenings, 

 and the smallest gain, 0.219 lb., on wheat. These two rations also showed the 

 greatest range in cost, a pound of gain being valued at 3.8 cts. on screenings 

 and 5.57 cts. on wheat. Considering all the lots, the average gain with wethers 

 was 0.2 lb. and with lambs 0.237 lb., the cost of a pound of gain in the two 

 cases being 7.92 cts. and 4.G1 cts. 



For feeding wethers, the author ranks the grains as follows when fed with 

 clover hay : Wheat, barley, oats, wheat screenings, and mixed grains ; and for 

 lambs — screenings, oats, barley, mixed grains, and wheat. 



When sold, some of the lambs which were light weight at the beginning of 

 the test were not sufficiently finished to bring the highest price, and the author 

 concludes that 3 months' time is not a sufliciently long feeding period for such 

 animals. 



In a test, covering (i5 days, of clover hay and grain, with and without roots, 

 which was made with 2 lots of 32 sheep each, the average gain per head per 

 day with the roots was 0.205 lb. and without roots 0.195 lb., the cost of a pound 

 of gain in the 2 cases being G.4 and 7.3 cts. The sheep included in this test had 

 been used in experiments on the effects of poisonous plants, and some of them 

 had lost weight during the summer. On an average they weighed 83 lbs. each 

 at the beginning of the trial. The roots fed in this and the following test con- 

 sisted of sugar beets, with occasionally mangels. 



Using one lot of 16 and one of 14 sheep, wheat screenings and mixed grain 

 (barley, oats, and bi-an 2:1:1) were compared, the ration in each case contain- 

 ing clover hay and roots in addition to grain. In 05 days the average gain on 

 screenings was 0.193 lb. and on grain 0.3 lb. and the cost of a pound of gain 0.2 

 and 4.4 cts. The feeding was then contimied foi- 58 days, both lots l>ii?ing fed 

 clover hay and roots with the mixed grain. During this period tla?. ayeragP;
