Thirty-fourth Annual Convention. ^^ 



The total milk produced by lot I was 39.386.4 pounds and that 

 "produced by lot II was 26,830.0 pounds. 39,836.4-26,830.0— 

 12,556.4 pounds the total difference in the amount of milk pro- 

 duced by the two lots. 



If the initial difference of 11.7 pounds per cow per week, 

 had been carried through the entire period it would have amount- 

 ed to 1,995.4 pounds. This sum taken from 12,556.4 pounds 

 equals 10,561.0 pounds or the difference due to feed. 



If milk were worth $1.00 per hundred pounds this would 

 mean a loss of $105.61 or $11.73 per cow. If the 18 cows had 

 been fed the poor ration the loss would have been $211.14. 



This would purchase 21 tons of clover hay at $10.00 per 

 ton. 21 tons of clover hay would be 18.5 lbs. per cow per day 

 for the entire time, which is much more than either lot received. 



There was also a great difference in the fat produced. Lot 

 I produced 1,257 pounds of fat and lot II produced 897.22 

 pounds, a difference of 359.7 pounds. 



As stated previously lot I consumed more food and made 

 better use of the food consumed. The following figures are 

 based on Henry's table for digestible nutriments. The total 

 digestible nutriments consumed by lot I was 19,425.93 pounds. 

 .493 pounds of nutriments were required to produce one pound of 

 milk. Lot II consumed 17,319.3 pounds of digestible nutriments 

 or .645 pounds for every pound of milk produced. Lot I con- 

 sumed 12 per cent more nutriments and made 30 per cent better 

 use of the nutriments consumed. 



There are at least two reasons why lot I consumed more. 

 1st, their ration was a little more palatable. 2nd, the better phy- 

 sical condition due to difference in the rations. The timothy hay 

 seemed to be one of the greatest disturbing factors. It was 

 practically impossible to. get these cows to consume moderately 

 large quantities of it. There was no difficulty in getting them to 

 take the corn meal and silage with clover hay. This illustrates 

 again the fact, that timothy hay is of little value a^-- feed for dairy 

 cattle and that the legume (clover, alfalfa, cowpeas, etc.) are 

 valuable. 



CONCLUSIONS. 



The above figures show that yuantity can not be made to 

 take the place of quality in the ration.
