Lots thus fed whey gained on the average 1.49 lbs. per 

 head daily, or nearly as much as the calves fed 10 lbs. of 

 skimmed milk a day. This satisfactory gain was due in all 

 probability to the fact that the whey was never allowed to 

 stand in a filthy tank or can, but was fed with reasonable 

 care and under sanitary conditions. Furthermore, a con- 

 centrate mixture rich in protein was used to make good the 

 casein which had been removed from the milk in the cheese 

 making process. The average feed cost of raising these 

 whey-fed calves to 6 months of age was $21.58. These re- 

 sults show that thrifty calves can be raided on whey readily 

 and cheaply when simple precautions are taken. 



Yellow vs. White Corn for Calf Feeding. 



Each year one lot of the whey-fed calves was fed yel- 

 low corn and another lot white corn in the concentrate mix- 

 ture. This was done as it had been recently found by Dr. 

 Steenbock of the Agricultural Chemistry Department that 

 yellow corn was rich in fat-soluoble vitamines, while white 

 corn contained little or none. It had also been found in 

 experiments with growing, fattening pigs carried on by the 

 Animal Husbandry Department that this made white corn 

 much inferior to yellow corn when fed with such supple- 

 ments as skim milk or tankage to pigs not on pasture. 



The calves fed white corn in these trials did fully as 

 well each year as those fed yellow corn. This result, which 

 was expected, was undoubtedly due to the fact that the 

 hay the calves consumed supplied considerable of these fat- 

 soluble vitamines. These results correspond to those se- 

 cured in the trials with pigs. Though yellow corn has been 

 superior to white corn when fed to pigs in dry lot with 

 supplements like skim milk or tankage, which are not rich 

 in these vitamines, white corn is just as good as yellow corn 

 for pigs on pasture or for those receiving alfalfa or other 

 legume hay.
