ANIMAL PEODUCTION-. 271 



An analysis of screenings gave the average percentage of grain as 26.0G, of 

 weed seeds 22.38, and of inert matter 51.56. It is estimated that a 100-lb. bag 

 of feed containing 20 per cent screenings wonld contain 4i per cent of weed 

 seeds. It was further found that recently grain screenings have been mixed 

 with distillers' dried grains, a practice which has not been observed heretofore.

Experiments with live stock, J. H. Grisdale, J. A. Clark, R. Robertson, 

 W. C. McKiLLiCAN, W. H. Fairfield, and G. H. Hutton (Canada Expt. Farms 

 Rpts. 1912, pp. 5-'f-60, 2.'f.h247, 26^, 265, 296-300, 380-3SIf, J,OS, 1,09).— Ito. con- 

 tinuation of work previously noted (E. S. R., 27, p. 371), tests in feeding 

 Shorthorn and Angus steers various proportions of bran, gluten meal, oil cake, 

 clover hay, corn silage, turnips, mangels, oat straw, and roots are reported. 

 Four lots of 15 steers made an average daily gain, for 350 days, ranging from 

 1.12 to 1.82 lbs., at costs ranging from 7.1 to 14.6 cts. per pound. 



In a test to determine the feeding value of straw as a roughage, a carload of 

 2 and 3-year-old steers were fed 155 days. The average profit per head realized, 

 after paying for all feed, was $15.56. » 



As a result of experiments in steer feeding it is calculated that " an increase 

 in selling price over buying price of from 1 to 11 cts. per pound is required to 

 cover a 4 to 6 months' feeding period." 



In a comparison of feeding steers outside with feeding in stable, twenty-one 

 3-year-old steers, chiefly Shorthorn and Hereford grades, were winter-fed Si 

 months. Lot 1, fed outside and amply supplied with hay and straw, together 

 with a grain ration, made an average daily gain per head of 1.28 lbs., costing 

 9.6 cts. per pound. Lot 2, fed in the stable and receiving straw, corn silage, 

 and roots in addition to the regular grain ration, made a corresponding gain 

 of 1.34 lbs., costing 8.9 cts. per pound. Lot 3, also fed in the stable and similarly 

 to lot 2 except that 3 lbs. of the grain ration was replaced by 3 lbs. of alfalfa 

 hay a part of the period, made a corresponding gain of 1.29 lbs. at a cost of 8.4 

 cts. Although slightly greater gains accrued from stalling and grain feeding, 

 the results show the profits possible from a better use of straw and coarse 

 grains for fattening steers, indicate that stalling is not essential, and give proof 

 of the great feeding value of alfalfa. 



In experiments in fattening lambs the value of roots and corn sila.ge as a 

 succulent feed was determined. Three lots of 10 each were fed 114 days. The 

 average daily gains per head were for the lot receiving turnips 0.28 lb., the 

 lot receiving silage 0.27 lb., and the lot receiving turnips and silage 1 : 1, 0.3 lb. 

 The respective costs per pound of gain were 8.04, 7.66, and 7.55 cts. 



Results indicate "corn silage to be of high value for fattening lambs, the 

 average net profit per lamb covering 3 years' experiments being $1.28 for the 

 turnip-fed lots as against $1.57 for the lots getting silage, and $1.34 for the 

 lots on a mixture of turnips and silage." 



In a 90-day test with 30 lambs to determine the value of roughage in fattening, 

 results were as follows: Lot 1, fed on alfalfa and clover hay in addition to the 

 regular grain ration, produced an average daily gain of 0.17 lb. per head.
