FIFTIETH ANNUAL CONVENTION 87 



calves made very good gains, though somewhat less than 

 Lot I, which was fed 14 pounds of skim milk a head daily. 

 They gained 1.52 pounds a head daily in comparison with 

 1.72 pounds for Lot I in corresponding trials. Owing to the 

 lesser amount of skim milk fed, the feed cost up to six 

 months of age was $21.32, compared with $23.80 for Lot I. 

 The calves receiving 14 pounds of skim milk daily were 

 slightly more growthy, although there was no apparent 

 difference in the vigor of the two lots, and the gains of the 

 calves limited to 10 pounds of skim milk a day were actu- 

 ally a trifle larger than is considered normal. 



These results show that good thrifty calves can be 

 raised on an allowance of skim milk limited to 10 pounds 

 daily, if a good concentrate mixture and good hay are fed 

 in addition. When an abundance of skim milk is at hand 

 it is best to feed the larger allowance given to Lot I. How- 

 ever, sometimes it may be advisable to limit the allowance 

 of skim milk fed to calves in order to have more skim milk 

 for young pigs or poultry.

Each year a third lot has been fed no skim milk, but 

 has been raised on a minimum amount of whole milk, which 

 did not exceed 400 pounds for each calf from birth, or 

 about 375 pounds from the fourth day after birth, when the 

 dam's milk was salable. This was supplemented by a sim- 

 ple concentrate mixture rich in protein, consisting of equal 

 parts ground oats, ground corn, linseed meal, and wheat 

 bran. After the calves were seven to nine weeks old, they 

 were fed only this mixture with hay, water and salt, no 

 expensive calf meal whatsoever being fed at any time. In 

 two trials these calves have made an average daily gain of 

 1.43 pounds at a feed cost of $22.64 per head to six months 

 of age. This lot gained slightly less than Lot II, fed 10 

 pounds of skim milk a head daily, but did remarkably well 

 considering the small amount of milk fed. In fact, the 

 gains would be considered normal for well-reared dairy 

 calves. 



These results show plainly that good thrifty calves can
