Feeds and Feeding. 



642. Ground oats compared with wheat bran. At the Wiscon- 

 sin Station, l Woll compared ground oats with wheat bran in two 

 feeding trials with six cows. Ten pounds of these concentrates 

 were given each cow daily with the results shown below: 



Returns from feeding ground oats and bran Wisconsin Station. 



Here is a return of 10 per cent, more milk and fat from oats 

 than from bran. The high value of oats in the dairy is well 

 illustrated in this trial. (175, 186) 



643. Sorghum-seed meaL At the New Jersey Station, 2 Cook 

 tested the relative merits of amber cane sorghum-seed meal and 

 corn meal for milk production. Three cows were fed the follow- 

 ing ration per 1, 000 pounds live weight: Twenty pounds brewers 7 

 grains, nine pounds corn meal, five pounds corn stover, and five 

 pounds bran. After receiving this ration twenty days, sorghum- 

 seed meal was gradually substituted for the corn meal until it re- 

 placed the latter the same amount, nine pounds, being fed. 

 When this feed had been used twenty days the ration was grad- 

 ually changed back to corn meal. The results for the three 

 periods are as follows: 



Period I. Cows fed corn meal averaged 28.1 pounds of milk each daily. 

 Period II. Cows fed sorghum meal averaged 24.6 pounds of milk each 



daily. 

 Period III. Cows fed corn meal averaged 27 pounds of milk each daily. 



It was observed that when the full sorghum-meal ration was 

 reached the yield of milk dropped immediately. On the other 

 hand, when changing from sorghum back to corn meal there was 

 an increase in the milk flow. These trials show that sorghum 

 meal is 10 per cent, less valuable than corn meal for milk pro- 

 duction. (197)
