517. deeding skim milk. — Pleisohmanni quotes an experiment 

 with six calves receiving skim milk only. Twelve pounds of 

 skim milk were requii-ed for one pound of gain. 



Beckhusen' reports feeding trials with calves receiving skim 

 milk and making an average daily gain of 2.1 pounds. One 

 poimd of gain was produced from 13.3 pounds of skim milk. 

 Prom 6. 1 to 28. 9 pounds of skim milk were required for one pound 

 of gain, according to the age of the animal. (357) 



5J8. Separator skim milk. — Du Eoi' fed 18 calves, averaging 

 91.5 pounds at birth, for 37 days. Each calf received 11.4 pounds 

 of full mUk and 896.7 pounds of separator skim milk, and gained 

 on the average 55.1 pounds, giving one pound of increase for 16 

 pounds of separator skim milk. In this trial one pound of new 

 mUk was considered equal to two pounds of skim milk. 



519. The Iowa Station tests. — Calf rearing with separator skim 

 mUk has been studied by Curtiss, of the Iowa Station, * who gives 

 the following recent important results. Milk from the college 

 dairy herd was fed immediately after it had passed through the 

 separator, the temperature being from 85 to 90 degrees Fahr. 

 The chief object of the experiments was to determine the best 

 grain to feed in connection with skim milk. Oil meal, oat meal 

 and corn meal, with a little ground flax seed additional, were 

 used. The first test, conducted during the summer, lasted sixty 

 days, with two calves, — one Short-horn and one Holsteia in each 

 lot, — averaging 182 pounds when the trial began. The second 

 trial, with two calves in each lot, conducted during the fall and 

 winter, lasted ninety days. The calves were high-grade Short- 

 horns, from two to three weeks old when the feeding began. The 

 third trial was conducted during the winter with four pure- 

 bred Short-horns in each lot, averaging 200 pounds when the 

 trial began. From thirteen to twenty pounds of skim milk were 

 fed to each calf daUy ta these trials. The calves in Lot I were
