to 10 lbs. a head daily, to represent conditions on farms 

 where the supply of skim milk available for the calves is 

 limited. These calves made very good gains, though some- 

 what less than Lot 1, which was fed 14 lbs. of skim milk a 

 head daily. They gained 1.52 lbs. a head daily in com- 

 parison with 1.72 lbs. for Lot 1. Owing to the lesser 

 amount of skim milk fed the feed cost up to 6 months of 

 age was $21.32, compared with $23.80 for Lot 1. The 

 calves receiving 14 lbs. 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 lim- 

 ited to 10 lbs. of skim milk a day were actually 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 lbs. 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 1. However, sometimes it may be advisable to 

 limit the allowance of skim milk fed the calves in order to 

 have more skim milk for young pigs. 



A Ration for Market Milk and Condensary Districts. 



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 lbs. for each calf from birth, or about 

 375 lbs. from the fourth day after birth, when the dam's 

 milk was salable. This was supplemented by a simple con- 

 centrate mixture, rich in protein, consisting of equal parts 

 ground oats, ground corn, linseed meal, and wheat bran. 

 These calves were allowed to eat up to 6 lbs. of this mixture 

 a head daily. Of course when the calves were small the 

 amount of concentrates eaten was relatively small. On the 

 average during the whole trial this lot ate 3.6 lbs. of concen- 

 trates a head daily, while Lot 1 fed the liberal allowance of 

 skim milk was fed on the average only 3 lbs. a day. After 

 the calves were 7 to 9 weeks old, they were fed only this 

 mixture with hay, water, and salt, no expensive calf meal 

 whatsoever being fed. In the two trials completed, these 

 calves have made an average daily gain of 1.43 lbs. at a
