Effects on butter of feeding cotton seed and cotton- 

 seed MEAL, N. T. LuPTON, LL. D.— To test the eflFects " on the volatile 

 acids, iiieltino' point, and specitic jriavity of the butter produced under 

 their influence," the followiiijj^ rations were fed to a lierd of 11 Jersey 

 cows in five periods of 7 days each, the periods being separated by inter- 

 mediate periods of 1 week each : 



Period I. 5 pounds ground o.its, 5 i)onn<1.s bran, 5 pounds corn meal.

 Period IV. Raw cotton seed and cotton-seed hulls ad libitum. 

 Period V, Cooked cotton seed and cotton-seed hulls ad libitum. 



The analyses of the feeding sturts used and the yield and composi- 

 tion of millv and butter in eacli ju'riod are tabulated. These data indi- 

 cate "a marked falling? otf in the (juantity of milk and an increase in 

 the amount of butter produced during the first three periods." In the 

 fourtli and fifth periods there was n decided decrease in the amount of 

 both milk and butter. 



From the first to the fourth periods the volatile acids of the butter 

 decreased and the melting point increased, the increase in melting 

 point amounting to about 8° C. In the fifth period there was a slight 

 increase in volatile acids and decrease in melting jtoint. '' No change 

 was observable in the color of the butter from feeding cotton seed and
