Experiments in feeding steers, N. Wolverton {Canada E.ept. Farms Rpts. 

 J 906, pp. 321, 322). — A steer feeding test at the Manitoba experimental farm 

 in which fodder corn and oat sheaves were compared, is briefly reported. On 

 the corn ration the average daily gain wirh 4 steers was 1 lb. G oz. in 143 days 

 and the profit .$6.93 per steer. In the case of the oat sheaf group the values 

 were 1 lb. S oz. and $G.10. 



Feeding- tests, A. Mackay (Canada Erpt. Farms Rpts. 1906, pp. 370-372, 

 pi. 1). — In a test undertaken at the Indian Head experimental farm to deter- 

 mine the effect of age on beef production, it was found that the average gain 

 of 3 yearling steers in 16 weeks was 150 lbs. per head and of 2 2-year-olds 245 

 lbs. per head. 



In a comparison made with 5 2-year-olds and 7 3-year-olds, the average gain 

 in 16 weeks was 211 and 166 lbs. per head, respectively. Of these two lots the 

 calculated profit was $6.74 and $4.67. 



Fattening range lambs, B. E. Caemichael {Ohio Sta. Bui. 187, pp. 7-35, 

 figs. 8). — Continuing earlier work (E. S. R., 18, p. 974), a proprietary stock 

 feed was compared with linseed meal for fattening lambs, as were medium and 

 heavy rations and the relative gains made by ewes and wether lambs. The 

 question of the manure production was also studied. Four lots, each containing 

 44 lambs, ewes and wethers together, were used and all were fed clover hay in 

 addition to concentrated feed. The grain rations fed and the average daily 

 gain per lamb in the 16 weeks of the test were corn and linseed meal 5 : 1, 0.236 

 lb. ; corn and condimental stock feed, 0.234 lb. ; heavy corn ration, 0.244 lb., and 

 medium corn ration, 0.231 lb. The cost of feed per pound of gain on .the 4 

 rations was 7.07, 6.58, 6.12, and 6.29 cts. The shrinkage in shipment and the 

 percentage dressed weight were recorded but no striking differences were noted 

 with the different lots. On an average the commercial value of the manure 

 produced ranged from $29.31 with the lot fed the heavy corn ration to .$.34.81 

 with the lot fed corn and linseed meal. The fertilizer value of the manures 

 was determined. 



In a discussion of this and earlier work at the station, the author concludes 

 that the rations were not markedly different as regards the feed required per 

 pound of gain and that it was not possible on the basis of these tests to deter- 

 mine whether the stock feed was either beneficial or harmful as the variations 

 noted with the ration containing it were not marked. 



"The results of one experiment [1906-7] indicate that lambs fed upon a 

 heavy grain ration will i)roduce gains with a lower consumption of feed than 

 will lambs fed upon a moderate grain ration. The plan of the test, however, 

 was interfered with somewhat and further work is needed before definite con- 

 clusions may safely be drawn. 



•• Wethers made approximately 10 per cent greater gains in live weight than 

 did ewes. . . . 



" Data secured show that manure from fattening lambs has a very high 

 fertilizing value, on the basis of its nitrogen, phosphoric acid, and potash 

 content. 



" The manure from the lots fed cotton-seed meal or linseed-oil meal, carried 

 in every instance more nitrogen, phosphoric acid, and potash than did that from 

 the lots fed a grain ration consisting solely of corn. In both experiments the 

 added value of the manure was more than offset liy the increased cost of the 

 linseed-oil meal or cotton-seed meal. The increased value of the manure pro- 

 duced from different feeds is worthy of consideration, since market conditions
