Feeds and Feeding. 



meal or corn meal for each 1.000 Ibs. of live weight, with the follow- 

 ing average returns: 



Daily milk yield 

 . per cow 



Period I, Ration containing corn meal 28.1 pounds 



Period II, Ration containing sorghum-seed meal 24. 6 pounds 



Period III, Ration containing corn meal _ 27.0 pounds 



It is shown that when the full sorghum-seed meal ration was fed 

 the yield of milk dropped, while on changing from sorghum-seed 

 meal back to corn meal there was an increased milk flow. These 

 trials show that sorghum-seed meal is at least 10 per ct. less valuable 

 than corn meal for milk production. (181) 



630. Soybean v. cotton-seed meal. At the Tennessee Station 1 

 Price compared ground soybeans with cotton-seed meal for milk pro- 

 duction with 2 lots each of four 2- and 3-yr.-old heifers, fed the fol- 

 lowing rations alternately during 3 periods of 30 days each:

It is shown that ground soybeans gave slightly better results than 

 cotton-seed meal. 



At the Massachusetts (Hatch) Station 2 2 lots of 4 cows each were 

 fed 6 weeks by the reversal method. To a basal ration of hay, silage, 

 and bran, an allowance of either ground soybeans or cotton-seed 

 meal was added in practically equal amounts. The ground soybeans 

 proved slightly superior to the cotton-seed meal as a milk and fat 

 producer, and the butter was of better quality. 



Otis of the Kansas Station 3 found that, when soybeans formed one- 

 half the concentrates, the butter from such feeding was so soft that 

 it was impossible to work it satisfactorily even tho chilled with ice 

 water. Since cotton-seed meal produces a hard butter and soybeans 

 a soft butter, the two in combination should form a most useful and 

 exceedingly rich nitrogenous concentrate for dairy cows. (201, 643)
