666 EXPERIMENT STATION RECORD. [Vol.38 



An appended article on The Grain Problem, by J. B. Lindsey, discusses the 

 relative values of feeds and their selection under present conditions. 



[Miscellaneous analyses], F. T. Shutt {Canada Expt. Farms Rpts. 1916, 

 pp. 121-125, 178, 179). — Analyses of bran, barley flour, oat flour, rice meal, flax 

 chaff, flax shives, elevator dust, mangels, several proprietary and by-product 

 feedstuffs, butter, poultry grit, and an egg preservative are reported. A test 

 of the egg preservative indicated no advantage over saturated limewater. 



Grazing experiment {Kansas Sta. Rpt. 1916, pp. 20, 21). — Plats protected 

 until the predominant species matured seed showed good results. Seeding with 

 a mixture of tame grasses did not establish a stand. With sweet clover, mow- 

 ing on level land was practical and kept down weeds. 



Cattle feeding, A. D. Favuxe {Wyoming Sta. Bui. 117 {1917), pp. 55-6-^).— 

 Experiments were made during three years comparing oat and pea silage with 

 alfalfa hay. The grain rations varied but were the same with lots directly 

 compared. 



The experiments during 1915-16 with beef cows were interrupted, but while 

 no elaborate results were obtained the data indicated that 7 lbs. of a 15-lb. 

 alfalfa ration could be replaced by 15 lbs. of oat and pea silage. 



During the winter of 1916-17 the cows were fed for 16 weeks as one lot with 

 and without oat and pea silage reversed every 4 weeks. With silage in the 

 ration they made an average daily gain per head of 0.55 lb. with a ration cost- 

 ing 13.8 cts. daily. Without silage in the ration they made an average daily 

 gain of 0.13 lb. on a daily cost of 13.7 cts. These results taken with others 

 previously obtained (E. S. R., 34, p. 467) indicate that oat and pea silage can 

 be substituted for alfalfa hay at 2 lbs. of silage to 1 lb. of hay. 



With growing cattle in 1914-15 during 161 days those with oat and pea silage 

 in the ration made an average daily gain per head of 0.84 lb. on a daily cost 

 of 11 cts. Those without silage in the ration made a daily gain of 0.8 lb. at 

 a cost of 13.4 cts. Approximately 9.5 lbs. of silage replaced 7 lbs. of alfalfa. 



During 113 days of the winter of 1915-16 growing heifers with oat and pea 

 silage in the ration made an average daily gain per head of 1 lb. costing 8.4 cts. 

 daily. Without silage they made an average daily gain of 0.6 lb. on a ration 

 costing 9.4 cts. per day. Ten lbs. of the silage more than replaced 5 lbs. of 

 alfalfa. With grain and alfalfa the cost of 100 lbs. of gain was $15.92, while 

 with the substitution of a part of the alfalfa with the silage it w-as $8.37. 



In 16 weeks' feeding with growing cattle during the winter of 1916-17 the lots 

 were reversed every 4 weeks. With silage in the ration they made an average 

 daily gain per head of 1.4 lbs. on a ration costing 10.8 cts. per day. Without 

 silage in the ration they made an average daily gain of 0.63 lb. on a ration 

 costing 11.4 cts. daily. With grain and alfalfa It cost $18.26 per 100 lbs. of 

 gain, while with silage in the ration it cost $7.70. 



[Cattle feeding investigations] {Kansas Sta. Rpt. 1916, pp. S4-S6). — One 

 hundred head of 3-year-old heifers were divided into five lots and fed for 20 

 days during the winter. The rations were feterlta silage and alfalfa, Kafir 

 corn silage and alfalfa, Kafir corn stover and alfalfa, Kafir corn stover and 

 alfalfa on range lot, and Sudan stover and Kafir corn silage. Kafir corn silage 

 and alfalfa made the greatest gain, the animals averaging 0.87 lb. daily at a 

 cost of 6.1 cts. per pound. The Kafir corn silage was better preserved and 

 more palatable than the feterlta silage. 



In another test of 120 days' duration 40 heifers were fed silage, alfalfa, and 

 straw and another 40 the same feed with the addition of 4.54 lbs. of corn-and- 

 cob meal and 1 lb. of linseed meal a day. The first lot made an average dally 

 gain per head of 0.92 lb. at a total feed cost of $4.73 per head. The second lot,
