For a second twenty-eight day period Lot I received 

 a ration of corn meal, 4 parts, and cottonseed meal, 3 

 parts, with corn silage, while Lot II received corn meal, 

 4 parts, and velvet bean meal, 6 parts, with corn silage. 



Feeds Used 



All of the feeds used were of good quality. The corn 

 was ground into a coarse meal as in the previous year. 

 The beans in the pods were also ground into a coarse 

 meal. The cottonseed meal was a good grade of meal 

 containing 36 per cent protein (7 per cent ammonia). 

 Figuring on the analysis from the protein basis velvet 

 beans, seed and pods, are found to be about one-half as 

 valuable as cottonseed meal of the above quality. As 

 Experiment A had shown that the velvet beans in the 

 pod were unpalatable to most of the cows, it was de- 

 cided to add corn meal to the bean and pod ration to 

 increase the palatability. The same amount of corn 

 was fed to each lot so that the variable factor was the 

 amount of velvet beans and cottonseed meal; these 

 were in the proportion of two to one. Thirty pounds 

 of corn silage was fed to each cow daily throughout 

 the experiment. 



The prices of the feeds were as follows : 



Cottonseed meal $40.00 per ton 



Velvet beans 22.50 per ton 



Corn 1.18 per bu. 



Silage 4.00 per ton 



Method of Feeding and Handling the Cows 



The cows all had the run of a small wooded lot dur- 

 ing the entire period of the test. Water was kept be- 

 fore them at all times and salt was given at regular 

 intervals. Milking and feeding was done twice daily 

 in the Station barn. Individual weights of the cows 

 were taken weekly. Records of production were kept 

 by weighing the milk and making a Babcock test of 

 each cow's milk at each milking.
