THIRTY-SEVENTH ANNUAL CONVENTION.

Relative Feeding Value of Cottonseed Meal and Linseed Meal for Milk 



Production. 



The experiment was divided into three periods of twenty- 

 fonr days each, the first seven days of each period being counted 

 as preliminary. In Periods I and III a ration was fed consisting 

 of 10 parts wheat bran, 10 parts cottonseed meal, 5 parts corn 

 meal, and 5 parts linseed meal. The grain ration during the 

 second period differed from this in that 10 parts of linseed meal 

 were fed only 5 parts of cottonseed meal. Of these grain mix- 

 tures, cows Nos. 1, 4 and 5 received 13 pounds daily, while Nos. 

 2 and 3 received 1 1 pounds daily. Each cow received uniformly 

 45 pounds of silage throughout the test. All of the cows were 

 in the early stages of lactation. 



The milk from each cow was weighed daily and composite 

 samples of it were tested weekly by the Babcock test. The cows 

 were regularly weighed once a week. 



Results. 



The results obtained from the individual cows during the 

 different periods are presented in the following table :
