37G EXPERIMENT STATION RECORD. [Vol.43* 



The nature of the feeds offered aiul the chief results are talnilaled below 

 Remits of feeding trials icith 50-11). Imnhs. 



1 Nearly 0.3 lb. was clover hay. 



The price schedule was as follows: Corn $1.25 a bushel, hominy feed $00, 

 cottonseed meal $67, corn silage $7.50, clover hay $25, and out straw $10 

 per ton. The initial cost of the lambs was 14.9 cts. a pound. Tlie averacrc 

 initial weight per head was about 51.3 lbs. and varied but little from lot to lot. 



Only a small amount of oat straw was eaten by lots 5 and 6, and the capacity 

 of oat straw to correct the deficiencies of corn silage as sole roughage was 

 not improved by changing tlie ratio of cottonseed meal and corn from 1:7 to 

 1:4. " With relatively cheap roughage and lilgh-priced concentrates, the 

 limited methods of feeding possess considerable merit. . . . But indications 

 favor the liberal use of concentrates under average conditions." If homitiy 

 feed had been charged at $45 a ton (the price of coni) the profit from lot s 

 would have been $2.35 per head. 



Sheep feeding e.\perinients at the Chapman Experiment Farm, G. L. Sut- 

 ton OVest. Aud. Dept. A(jr. Bui. 10 {1920), pp. 8, ft(js. 2). — Experiments Avere 

 made in 1017, 1918, and 1919 to determine suitable home-grown rations for 

 carrying sheep over the period of feed scarcity whicli normally occurs in Aus- 

 tralia in April and May at the end of the dry season. Hoggets and nonpreg- 

 nant ewes were maintained for several months in a tlirifty condition on 1 lb. 

 per head per day of chaffed wheat or chaffed oat hay. Pregnant ewes fed 0.6 

 lb. of Avhole oats and given access to wheat stubble came through satisfactorily. 



The liay was chaffed after being well cured and the chemical composition of 

 botli kinds is reported. Comparisons were not made with imcut liay. 



Pasturing alfalfa with hogs, R. E. Blair {U. S. Dcpt. Ayr., Bept. Circ. 15 

 {1920), pp. 7^-76).— The pasturing tests of 1916 and 1917 at the Yuma Itecla- 

 niation Project Experiment Farm (E. S. R., 40, p. 472) were repeated in 1918 

 except that no pigs were available for the spring test. On July 29, eleven 3S-lb. 

 grade Duroc-Jersey sliotes were turned on a 0.75 acre-plat of tliird-year Peru- 

 vian alfalfa and given a 2 per cent grain ration. During most of the time the 

 supplemental grain was ci'^cked milo, but for 28 days in the fall rolled barley 

 was iised without apparent effect on the gains. Three hogs were removed 

 October 21 and tlie test closed November 25. After the 119 days of pasture the 

 hogs averaged 96 lbs. in weight. They had gained the equivalent of 826.7 lbs. 

 per acre and required 2.44 lbs. of .grain per pound of gain. With pork at 7 cts. 

 and grain at 1 ct. a pound, the prices previously used, the pasture gave a net
