EXPERIMENT STATION. 109 



The ration fed to a herd of six mixed grade cows at the College 

 Farm, has given perfect satisfaction ; it was made up as follows, 

 the calculation being for 1,000 lbs. live weight per day : 



Containing pounds of digestible 



Protein. Fat. Stare li. 



6 lbs. Clover Hay. 0.47 .09 2.27 



1 a lbs. Wheat Straw, 0.11 .04 4.88 



20 lbs. Brewers' Grains, 0.99 .33 2.86 



20 lbs. Turnips, 0.26 2.06 



2 lbs. Cotton Seed Meal, 0.66 .22 0.24 



Total, 2.45 .65 12.31 



The total dry matter was, 25.5 lbs. 



The total weight of the six cows, taken with all usual precau- 

 tions, was 5,770 lbs. To find the amount of fodder and feed 

 needed for the herd, we have therefoi-e to multiply the weights, 

 which, as above stated, are for 1,000 lbs., by 5.77 ; for example : 



6 lbs. of Clover Hay, x 5.77 = 34^ pounds. 



13 lbs. Wheat Straw, ... x 5.77 = 75 " 



20 lbs. Brewers' Grains, x 5.77 = 115 " 



20 lbs. Turnips, x 5.77 r= 115 



2 lbs. Cotton Seed Meal, .. . x 5.77 = lU 



The daily cost of the ration for 6 cows can now be easily com- 

 jtuted: 



35 lbs. Clover Hay, at $15 per ton, =26 cents. 



75 lbs. Wheat Straw, at S7 per ton,... ' =26 " 



115 lbs. Brewers' Grains, at $5 per ton, =29 " 



115 lbs. Turnips, 10c. per bushel, .. =19 " 



Hi lbs. Cotton Seed Meal, at |26 per ton, =15 " 



$1.15 

 Daily cost for each cow, 19 cents. 



The straw was passed through a cutter and thoroughly mixed 

 with the Brewers' Grains, Cotton Seed Meal and Turnips. The 

 mixture was fed in equal portions morning and evening. The 

 hay was fed at mid-day. 



The cows were mixed grades taken from a herd of twenty-four 

 head. They were milked twice daily — the milk of each cow being 

 carefully weighed, and a sample of the mixed milk together with 

 the record of the yield, sent each day to the Station by Mr. 

 Theodore West, Farm Superintendent.
