Feeds and Feeding. 



cotton-seed meal, wheat meal, and corn stover fed without limit. Later 

 linseed meal was substituted for the cotton-seed meal : 



Linseed meal compared with cotton-seed meal. 



The cows receiving the cotton-seed meal produced somewhat more 

 milk but no more fat than those getting linseed meal. Hills of the 

 Vermont Station 1 found that cotton-seed meal seemed to possess a 

 small tho measurable advantage over linseed meal for dairy cows. 

 In view of these findings it is reasonable to hold that linseed meal 

 is siightly less valuable than cotton-seed meal. Linseed meal tends 

 to produce a soft butter and therefore may sometimes be advan- 

 tageously fed in rations which would otherwise produce a tallowy 

 butter. (200) 



641. Cotton-seed meal. At the South Carolina Station 2 Michels 

 and Burgess fed 21 cows for 3 alternate periods averaging 27 days 

 each on the rations shown below. Both lots received all the corn 

 silage they would consume. In the second period 5.1 Ibs. of cotton- 

 seed meal formed the sole concentrate, while in the first and third 

 periods 3.4 Ibs. of wheat bran replaced 1.7 Ibs. of cotton-seed meal. 



At the New Jersey Station 3 Lane fed 4 cows for 66 days on either 

 cotton-seed meal or a mixture of equal parts of wheat bran and dried 

 brewers grains. The results of both trials are shown in the table on 

 the next page. 



From the South Carolina trial we learn that when 1.7 Ibs. of 

 cotton-seed meal was replaced by 3.4 Ibs. of wheat bran the yield 

 of milk and fat was slightly decreased. In the New Jersey trial, 

 where corn silage and corn stover formed the roughage, 4.5 Ibs. of 

 cotton-seed meal did not prove quite equal to 10 Ibs. of a mixture 

 of wheat bran and dried brewers' grains. Michels concludes that 

 1 Ib. of cotton-seed meal is equal to 2 Ibs. of wheat bran for milk
