ANIMAL PRODUCTION. 397 



and then mixed with skim milk, the proportions fed per day being 4 oz. copra cake, 

 8 oz. pollard, 2 oz. molasses, and 3 gal. skim milk. 



The cod-liver oil ration "is easily fed, ami entails little labor in its preparation and 

 mixing. The calves relished the food and appeared in better condition at the end 

 of the test." The copra-cake ration "requires more attention to prepare, and the 

 calves did not thrive so well. The evidence is distinctly in favor of the cod-liver oil 

 ration, both in the cost of ration and in the increase in weight, as well as in the time 

 employed in preparing and feeding the ration." 



Eggs as a feeding- stuff for calves, Rarkin (Jour. Soc. Agr. Suisse Romande, 44 

 (1903), No. 10, pp. 252-257). — A summary of data which, in the author's opinion, 

 indicate that eggs are very valuable for supplementing skim milk in calf feeding. In 

 one of the tests a calf weighing 60 kg. was fed 24 days, on an average, a ration of 14 

 liters of skim milk with 6 eggs. The average daily gain was 1.55 kg. per day. 



Stock feeding experiments ( Oklahoma Sta. Rpt. 1904, PP- 41-46)- — Using lots of 

 5 steers each, different combinations of cotton seed, Kafir-corn meal, shelled corn, 

 corn meal, alfalfa hay, prairie grass hay, and wheat straw were tested for 140 days. 

 Before the close of the test 2 of the animals in one of the lots were removed on 

 account of sickness or injury. The gains in weight ranged from 1.14 lbs. per head 

 per day on cotton-seed meal and wheat .straw to 2.34 lbs. on cotton seed, Kafir-corn 

 meal, alfalfa hay, and wheat straw. In every case the amounts of feed consumed 

 were recorded. When the steers were sold and slaughtered, the dressed weight 

 ranged from 56.7 per cent of the live weight in the case of the lot fed cotton-seed 

 meal, shelled corn, prairie-grass hay, and wheat straw, to 59.2 per cent in the case of 

 the lot fed corn meal and alfalfa hay. 



Three pigs followed each lot of steers. All of them made very small gains except 

 those following the lot fed cotton-seed meal, shelled corn, prairie-grass hay, and 

 wheat straw. This lot made fair gains. During the latter part of the test, to insure 

 satisfactory gains, all the pigs were fed a liberal allowance of corn meal in addition 

 to the feed which they could gather. The total increase in weight ranged from 332 

 lbs. with the lot following the steers fed cotton seed, alfalfa hay, and wheat straw to 

 531 lbs. with the lot following the steers fed shelled corn mentioned above. Con- 

 sidering both the steers and pigs, the greatest profit, $29. 19, was obtained on the 

 ration of cotton seed, Kafir-corn meal, alfalfa hay, and wheat straw. 



Feeding and grazing experiments with beef cattle, J. F. Duggar (Alabama 

 College Sta. Bui. 128, pp. 51-88, figs. 4)- — Various problems connected with the profit- 

 able feeding of cattle under local conditions were studied. In a test made with 4 

 lots of 5 steers each, covering 84 days, cotton seed was compared with cotton-seed 

 meal, and sorghum hay with a mixture of sorghum hay and cowpea hay and with 

 shredded corn stover. 



The steers in lot 1, fed cotton-seed meal and corn chop 2:1 with sorghum hay, 

 made an average daily gain of 2.23 lbs. per head, requiring 4.82 lbs. of grain and 6.56 

 lbs. of coarse fodder per pound of gain. The steers in lot 3, feed cotton seed and 

 corn chop 3:1 with sorghum hay, made an average daily gain of 1.19 lbs. per head 

 and required 8.12 lbs. of grain and 11.09 lbs. of coarse fodder per pound of gain. On 

 a ration of cotton seed and corn chop 3:1 with sorghum hay and cowpea vine hay in 

 equal parts, the steers in lot 2 made an average daily gain of 1.93 lbs. per head, 

 requiring 5.41 lbs. grain and 6.85 lbs. coarse fodder per pound of gain. 



On the same grain ration but with shredded corn stover, the average daily gain of 

 the steers in lot 4 was 0.98 lb. per head, the grain required per pound of gain being 

 9.41 lbs. and the coarse fodder 10.23 lbs. The financial returns are discussed on the 

 basis of high, medium, and low values for the different feeding stuffs. "Whatever 

 the price of feed the ration of mixed cowpea and sorghum hay, cotton seed, and corn 

 chop was the most profitable.
