766 EXPERIMENT STATION RECORD. [Vol.36 



In a test in 1914-15, comparing cottonseed meal with alfalfa hay as supple- 

 ments for cane silage for breeding ewes, a lot of ten ewes fed an average daily 

 ration of 5.85 lbs. of cane silage and 0.5 lb. of cottonseed meal, made an average 

 daily gain of 0.4 lb. per ewe for 105 days. During the same period another lot 

 of ten ewes fed an average daily ration of 4.87 lbs. of cane silage and 1.5 lbs. 

 of alfalfa hay gained 0.16 lb. per ewe daily. The nine ewes that lambed in lot 

 1 gave birth to 13 lambs, three of which were strong, six of medium vigor, two 

 were weak, and two were born dead. Only eight ewes lambed in lot 2, and 

 from these eight were nine lambs, five of which were strong, two of medium 

 vigor, one weak, and one dead. 



A comparison was made of ewes of different breeds and crosses on a main- 

 tenance ration of alfalfa hay and corn and Kafir corn siiage in 1915-16. The 

 experiment lasted from 79 to 84 days for the different lots. The average daily 

 gain and feed cost per ewe for the dilferent lots were as follows: Lot 1, con- 

 sisting of nine pure-bred Shropshire and four cross-bred Shropshire-JNIerino 

 ewes, 0.107 lb. and 1.76 cts. ; lot 2, consisting of 17 pure-bred Dorset ewes, 0.19 

 lb. and 1.91 cts. ; lot 3, consisting of eight pure-bred American Merino and five 

 pure-bred Rambouillet ewes, 0.193 lb. and 1.71 cts. ; lot 4, consisting of 12 Fi 

 Shropshire-Dorset ewes, 0.202 lb. and 1.84 cts. ; lot 5, consisting of 10 Fi Merino- 

 Dorset ewes, 0.19 lb. and 1.89 cts. ; and lot 6, consisting of 15 ewes that were 

 the offspring of pure-bred rams and cross-bred ewes, 0.16 lb. and 1.65 cts. No 

 conclusions are drawn from this experiment. 



In an experiment comparing corn silage with alfalfa hay as roughage for 

 fattening lambs a lot of six pure-bred and cross-bred wether lambs fed an 

 average daily ration of 3.18 lbs. of silage and 2.03 lbs. of a mixture of Kafir 

 corn and cottonseed meal (2:1 by weight) gained 0.42 lb. per head daily for 

 63 days at a cost of 6.82 cts. per pound of gain. During the same period 

 another lot of six wether lambs of the same breeding, on an average daily 

 ration of 2.88 lbs. of alfalfa hay and 2.03 lbs. of the above grain mixture, 

 gained 0.55 lb. per head daily at a cost of 7.53 cts. per pound of gain. The 

 market finish of both lots was practically the same. In another test beginning 

 October 22, 1913, 30 pure-bred and cross-bred lambs averaging about 92 lbs. 

 per head were divided into two lots of 15 lambs each and fed for 49 days. 

 These lambs had received grain on pasture and were in good condition. Lot 1, 

 on a mixture of Kafir corn silage, alfalfa hay, and corn chop, made an average 

 daily gain of 0.69 lb. per lamb at a cost of 3.96 cts. per pound of gain. Lot 2, 

 led the same mixture as lot 1 and in addition 0.234 lb. of cottonseed meal per 

 head daily, made an average daily gain of 0.62 lb. per lamb at a cost of 4.24 

 cts. per pound of gain. 



In another test with 20 pure-bred Shropshire lambs, cottonseed meal was 

 compared with alfalfa hay as supplements for cane silage and Kafir corn chop. 

 The ten lambs receiving an average daily ration of 2.95 lbs. of silage, 1.19 lbs. 

 of Kafir corn chop, and 0.49 lb. of cottonseed meal made an average daily gain 

 of 0.35 lb. per head for 84 days at a cost of 7.11 cts. per pound of gain. During 

 the same period, the ten lambs fed 3.02 lbs. of silage, 1.13 lbs. of alfalfa hay, 

 and 1.23 lbs. of Kafir corn chop per head daily, made an average daily gain 

 of 0.46 lb. per lamb at a cost of 5.74 cts. per pound of gain.
