1016 EXPERIMENT STATION RECORD. 



The cost and profit are based oi. liaj at $10, corn fodder $4, corn 

 meal $18, cotton-seed meal $26, bran $14, and cotton-seed feed $11.50 

 per ton, butter at 25 cts. per pound, and skim milk at 20 cts. per 100 lbs. 



"A ration of cotton-seed feed and bran produced 19 per cent less milk and 10 per 

 cent less butter than one of corn fodder, mixed hay, com meal, and cotton-seed meal 

 containing an equal amount of dry matter. 



" Tlie feed cost per pound of milk was 13 per cent lower and per pound of butter 

 5 per cent lower on the hay and fodder ration than on the cotton-seed feed ration. 



"The net profit per day and head was 17 per cent less on the cotton-seed feed 

 ration than on the hay and fodder ration." 



The experiment was repeated, using a second lot of cotton-seed feed. 

 The general plan of the experiment was practically the same as the 

 first, the lots being reversed on the rations. Each lot received 2 lbs. of 

 bran and 6 lbs. of Buffalo gluten meal per head daily, and one lot had 

 clover hay, while the other had cotton-seed feed ad libitum as coarse 

 fodder. Four pounds of corn meal was fed to offset the cotton-seed 

 meal in the cotton-seed feed, but this turned out to be too much, as 

 the cows did not eat as much of the feed as was anticipated. From 9^ 

 to 12J lbs. of the cotton-seed feed was eaten daily, which would contain 

 less than 2 lbs. of cotton-seed meal. 



The average daily yield on the cotton-seed feed ration was 15.25 lbs. 

 of milk and 0.763 lb. of butter fat, and on the clover hay ration 17.9 

 lbs. of milk and 0.814 lb. of butter fat. 



"As in the former experiment, the cotton-seed feed ration produced less milk and 

 butter than the ration with which it was compared. . . . 



"The financial results of this experiment are slightly in favor of the cotton-seed 

 feed ration, and thus apparently contradict those of the previous trial. It is to be 

 borne in mind, however, that in this second trial the cotton-seed feed was compared 

 with a heavier ration. . . . 



"Plainly, however, the first method of comparison is the one best adapted to give 

 a fair idea of the value of the new feed, and hence we shall give much more weight 

 in our conclusions to the results of the first experiment." 



The authors' conclusions are: 



" (1) The results of these investigations indicate that cotton-seed feed is too expen- 

 sive, in proportion to the amount of food which it contains, to successfully compete 

 on equal terms with ordinary dairy foods at average prices. 



" (2) The results of these experiments show that under average market conditions 

 a very considerable profit may be realized by the conversion of dairy foods into milk 

 and butter. The net profit over the estimated cost of feed and care in these experi- 

 ments ranged from 77 to 95 per cent." 



Pig feeding, different breeds, W. P. Wheeler {New York State 

 Sta. Bpt. 1893, pp. 224-234). 



Synopsis. — Two experiments in feeding young pigs of different breeds from birth until 

 a little over 7 months old, in one case, and until 10 weeks old in the other. In 

 the experiment for 7 months the average gain, cost of gain, and shrinkage in 

 dressing were practically the same for all breeds. In the other experiment the 

 Poland China and Berkshires made slightly the best gains, but the Duroc and 

 the Duroc-Poland China cross the most economical. 



The record is given for 8 Berkshires, 8 Poland Chinas, and 6 Poland 

 China-Duroc cross fed from birth until a little over 7 mouths old, and 

 for 3 Berkshire-Cheshire cross until 4^ months old. They were kept
