PROBLEMS. 



1. How many pounds each of protein and carbohydrates and fat will 

 be required to supply a 1,200 cow giving 30 pounds of milk daily testing 



4 per cent fat? What is the nutritive ratio of the feed? 



2. A cow weighed 1,300 pounds when she was dry ; three months 

 after she was fresh she weighed 1,200 pounds, and gave 60 pounds of 



5 per cent milk daily, what was the difference in amount of protein and 

 carbohydrates and fat required when she was dry and when she was in the 

 flow of milk given above? 



It is very evident from the foregoing discussion that there 

 should be upon every farm, a good scale for weighing the ani- 

 mals of the farm, a Babcock tester and milk scales. 



PROBLEMS. 



One of the dairy queens, Finderne Holin^en Fayne a Holstein 

 cow, on March 24, 1915, finished a 365-consecutive day test having pro- 

 duced 24,612.8 pounds of milk and 1,116.05 pounds of butterfat. On 

 the basis of butter which contains 85 per cent of fat, her production 

 was equivalent to how many pounds of butter?
