Bullock feeding experiment [Midland Agr. aud Dainj liixl. lKI)ii/xtoti] llpl. V.tOl, 

 pp. 71-76). — A test was made with 3 lots of 2 yteers each of the relative merits of 

 nndecorticated cotton-seed cake and Hnseed cake, 1:1; ground decorticated cotton- 

 seed cake and maize meal, 1:1:2, and undecorticated cotton-seed cake, in every 

 case supplementing a ration of Swedish turnips, chaffed barley straw, and hay. For 

 15 days before the test proper began the grain ration of all the steers consisted of 

 undecorticated cotton-seed cake. The test as a whole covered 124 days. The aver- 

 age gain per head in the 3 lots was 2.18, 2.1, and 1.73 lbs., respectively. Taking 

 into account both the gains made and the profits per lot, the conclusion is reached 

 that there is very little profit in feeding the steers and that tlie differences in gains 

 made are not marked enough to warrant any deductions.

Comparative results from feeding lambs, 1-year wethers, 2-year wethers, 

 and aged ewes, R. S. Shaw {Montana St a. Bid. 35, pp. I-I4, fig^^. 2). — The relative 

 profits obtained in feeding sheep of different ages under local conditions was tested 

 with 4 lots, conaprising, respectively, 55 lambs, 51 year-old wethers, 53 2-year-old 

 wethers, and 53 old ewes. All the lots were fed 0.68 lb. unground barley per head 

 daily in addition to clover hay, the amount eaten in the different lots being 2.05, 

 3.77, 4.05, and 2.33 lbs., respectively. The average weight of the animals in the 4 lots 

 at the beginning of the test was 62.9, 94.9, 115.7, and91.6 lbs., respectively. IntheSB 

 days covered by the test the average gains per head were: Lambs, 23.7; yearling 

 wethers, 23.5; 2-year-olds, 24.3, and old ewes, 15.6 lbs. The dry matter eaten per 

 pound of gain was 10.16, 16.6, 17.1, and 17.5 lbs., and the average cost of a pound of 

 gain in the 4 lots was 4.18, 5.83, 5.90, and 6.78 cts., respectively. All the lots were 

 sold in Chicago, the lambs yielding a jjrofit of $1.73, the yearlings $1.40, the 2- year-olds 

 $1.57, and the old ewes 1.8 cts. per head. During transportation the shrinkage in 

 weight in the case of the ewes was 11.3 per cent and in the case of the other lots it 

 was very nearly equal, averaging 8.6 per cent. According to the author — 



" The feeding of lambs for market is more profitable than wethers or ewes, pro- 

 viding the ration is so adjusted as to give their rapid increase a finish. Owing to 

 the growthy tendency of the lamb, its ration must possess more fat-producing mate- 

 rial than the mature sheep. Where grain is not available, the mature wether, though 

 making a smaller proportionate increase, will fatten more readily than the laml) on 

 clover or alfalfa alone. The use of" from 2 to f lb. of grain, along with clover or alfalfa, 

 throughout a period of from 70 to 90 days, is necessary to produce a proper finish for 

 shii^i^ing. ... 



"The suggestion, resulting from personal experience, is offered . . . that sheep 

 will withstand shipping better if kept on a limited allowance during transit rather 

 than on full feed; but that feed and rest are essential toward the close of trip. The 

 total net profit from the car of sheep was $251.29. Even though the cost of market- 

 ing is a large item, still this is offset by cheap feeders and an abundance of cheap 

 food of good finality, which renders the feeding business a profitable industry." 



The results of a swine feeding experiment, W. J. Kennedy and F. R. Mar- 

 shall {loira Sta. Bid. 65, pp. 209-222, Jign. .:>) . — This test was undertaken to learn the 

 value of beef meal, tankage, and Standard Stock Food when fed to pigs in addition 

 to corn meal. These animal feeding stuffs, which are slaughterhouse by-products, 

 have been recommended on account of their high protein and ash content. The
