1 62 THE COST OF RAISING CALVES 



SUMMARY OF TABLES 



Eight calves luuler 5 weeks old. Average weekly gain 7.6 

 pounds. Average weekly cost 40.6 cents. 



Eight calves from 5 to 9 weeks old. Average weekly gain 

 9.1 pounds. Average weekly cost 36 7 cents. 



Eiglit calves from 9 to 13 weeks old. Average weekly gain 

 II. 8 pounds. Average weekly cost 43.1 cents. 



Eight calves from 13 to 20 weeks old. Average weekly gain 

 10 pounds. Average weekly cost 52.9 cents. 



Six calves from 4 to S months old. Average weekly gain 

 II. I pounds. Average weekly cost 63.7 cents. 



Two calves from S to 13 months old. Average weekly gain 

 5.25 pounds. Average weekly cost 58. 3 cents. 



Four heifers from 13 to 16 months old. Average weekly 

 gain 6.12 pounds. Average weekl}' cost 65.1 cents. 



The heifers i. 2, 3, and 4, were maintained on pasturage 

 from July 24 until October 26, 1897, a period of 13 weeks and 

 2 days. The total gain in weight of the four animals was 313 

 pounds, or an average weekly gain of 5.9 pounds per head. 



During the feeding periods recorded in the foregoing tables, 

 comparisons were made between cooked, ground flax-seed, and 

 cooked middlings as a substitute for the fat in milk, and also 

 between rations including the cooked food and those without it. 



In the first named trial, the calves were between 5 and 8 

 months old, and the middlings proved to be a satisfactory sub- 

 stitute for the ground flax-seed, the cost being less and the gain 

 in weight large enough for the purpose though a little smaller 

 than on the flax-seed. 



The calves in the second trial mentioned were also over five 

 months old. The substitution of the dry grain lessened the cost 

 and the gain was sufficiently large, although smaller than in the 

 previous period. 



These trials show that for calves at the age of those described, 

 there is no object in using anything but dry grain and hay along 

 with the skim-milk, unless the greatest possible amount of 

 growth is desired.
