FIFTIETH ANNUAL CONVENTION 89 



istry Department that yellow corn was rich in fat-soluble 

 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 supplements as skim milk or tankage to pigs 

 not on pasture. 



These 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-sol- 

 uble vitamines. These results correspond to those secured 

 in the trials with pigs. Though yellow corn has been supe- 

 rior to white corn when fed to pigs in dry lot with supple- 

 ments 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. 



Do Not Neglect Watering Calves, 



The importance of supplying plenty of water to dairy 

 calves even when fed a fairly liberal allowance of skim 

 milk is not appreciated by many dairymen. To gain definite 

 information on this matter, in two of the trials a lot was fed 

 the same ration as Lot I, except that no water was given 

 these calves. Both lots received a liberal allowance of 

 skim milk, the good concentrate mixture mentioned previ- 

 ously, and common salt. Lot I received what water they 

 would drink twice daily, while the other lot had no water 

 except that occurring naturally in the skim milk and the 

 trifle in the "dry" concentrates and hay. The calves not 

 given additional water gained only 1.32 pounds a head 

 daily, while Lot I watered twice daily gained 1.86 pounds 

 during corresponding trials. The lack of water, therefore, 

 causes a surprising difference in the gains of calves. No 

 farmer who wishes to grow his calves rapidly and well can 

 afford to neglect supplying them with plenty of water — the 

 cheapest item in the ration.
