Calf Rearing Experiments. 



Throughout the season the calves had the run of eight statute 

 acres of fair grass land, and were housed at night. They were 

 tied to be fed twice daily, morning and evening. A good supply 

 of water was available on the pasture. 



The separated milk was delivered once per day from the 

 creamery, and until used was set in barrels of cold water. The 

 milk fed in the evening was usually perfectly sweet, but the 

 morning feed was more or less sour. The milk was given at a 

 temperature of from 80 to 90 degrees F. Up to July 1st the 

 linseed cake (together with the Indian meal, in the case of 

 Lot IV.) was steeped in hot water twelve hours before being 

 used, and was mixed with the milk at feeding time. From July 1st 

 onwards the linseed cake was given after the milk to the calves 

 in Lots I., II., and III. For Lot IV. the cake and meal were 

 mixed and then moistened with warm water or milk. The 

 measured allowance per head of cod liver oil fed to Lot 1 1 1, was 

 put into a bucket and the milk then poured on the oil. This is 

 the best method of mixing the milk and oil. Well refined oil of 

 a good quality was used, and the calves showed no dislike to 

 the mixture. 



The average weight per head of the calves in each lot on 

 June 1 2th, 1 90 1, and the average gain in weight from June 12th 

 to October 30th, were as follows : — 



Average weight Average gain in weight 



on June 12th. in 20 weeks to Oct. 30th.

Do. in. ... ... 137-8 176-2 



Do. IV 137-4 180-2 



The calves reared on whole milk made the largest increase ; 

 their average increase in weight per head was 40^ lb. greater 

 than the average increase of the calves reared on a mixture of 

 separated and whole milk, which gave the second highest 

 returns. There was but little difference in the weight gained by 

 the calves in Lots III. and IV., but their increase was about 

 20 lb. per head less than that of the calves in Lot II. 



These results must be considered from a financial standpoint,, 

 for the question of most importance to farmers is not so much
