CALF RAISING 



181 



In the figures given the Jersey spring calves averaged 

 268 pounds at six months, while the fall calves averaged 250. 

 The records for the same calves show that at one year of age 

 the spring calves averaged 360 pounds, while the fall calves 

 reached 440. 



Comparison of Whole Milk and Skim Milk Calves. The 

 following table from the Kansas Experiment Station l gives 

 the comparative gains made by three lots of ten calves each, 

 fed on skim milk, on whole milk, and nursed by the dam. 



The calves nursed by the dams and those fed whole milk 

 made a slightly better gain than those fed skim milk, but it 

 was at a much greater expense, as shown in the table. The 

 skim milk calves consumed 122 pounds of grain per 100 pounds 

 gain, while the whole milk calves consumed 58 pounds grain 

 and 31.8 pounds of fat in the milk. At this rate 100 pounds 

 of grain was equivalent in feeding value to 48 pounds of fat. 

 The economy of substituting the butter fat by grain is appar- 

 ent, since the market value of butter fat is usually from 

 twenty to thirty times that of corn meal fed to supplement 

 skim milk. In the experiment quoted the calves which were 

 steers were later put in the feed lot, and all fed for seven 

 months. The best gains made were made by the skim milk
