Feeds and Feeding. 



In the third trial both lots were soiled with grass, one lot get- 

 ting grass only, while the second received grain in addition. In 

 this trial the grain-fed cows gave just enough more fat to pay for 

 the grain received. 



In order to determine the value of grain for cows on pasture 

 under practical conditions, a fourth trial was conducted with 

 a herd of cows owned by a New York farmer. This herd, con- 

 sisting of sixteen cows which had been lightly fed during the 

 winter, was divided into two lots of eight each, all grazing in the 

 same pasture. Each cow of Lot I was fed four quarts daily of a 

 mixture of two parts corn meal, one part wheat bran and one 

 part cotton-seed meal, by weight. The test began May 23. 

 August 10, the pastures becoming poor, both lots were fed green 

 fodder corn. On September 9, green millet was substituted for 

 the fodder corn. October 1, meadow grass was substituted for 

 the millet, and this was followed October 13 with pumpkins in 

 generous quantity. It will be noted that the cows getting no 

 grain were much better fed than those on most farms. The find- 

 ings of the trial, which lasted twenty-two weeks, are here pre- 

 sented:

"We learn from the above that the eight cows in Lot I were fed 

 5,200 pounds of grain and gave 4,931 pounds or 28 per cent, more 

 milk than those getting no grain. Both lots gained in weight, 

 Lot I leading by fifty-three pounds on the average for each cow. 

 The use of grain did not change the composition of the milk.
