The lack of finish of the steers receiving cottonseed meal 

 indicated that it would have required a feeding period of 120 

 days to put them in good marketable condition, and 150 days 

 for those receiving cotton seed, had they continued to make 

 the same rate of gain. 



FEEDING COTTON SEED TO PREGNANT EWES 



Twenty head of pregnant ewes were fed a daily ration con- 

 sisting of 34 pound of cotton seed with a liberal allowance of 

 corn silage for a period of three weeks prior to lambing. Cow- 

 pea straw was available at all times, and the ewes had the 

 freedom of a scanty pasture along an enclosed ditch bank. 

 No scouring or other ill effects resulted. The ewes remained 

 in thrifty condition and raised healthy, vigorous lambs. 



The Hereford heifer which is being maintained on an 

 exclusive ration of alfalfa hay, dropped a calf on February 

 11, 1921. Both animals are doing nicely with no indication of 

 any ill effects from the hay ration. It is planned to carry on 

 this test for several years to study the effect on the progeny of 

 the heifer of the continuous use of alfalfa hay as the sole feed. 



The crop of wool produced this year is the largest that 

 has been sheared from the University flock, in point of indi- 

 vidual production. The Rambouillet ewes of all ages gave 

 an average fleece of 12.8 pounds, which is 22 percent more 

 than the average production of the Shropshire ewes; while the 

 Rambouillet rams yielded an average fleece of 15.2 pounds, 

 or 38 percent more than the Shropshire rams. Sheepmen 

 will be interested in following these records from year to year.
