FEEDING DAIBT CATTLE 

 From the table we learn : — 



207 



Nutrients for 1 lb. of 3 per cent milk . . 

 Nutrients for maintenance 100 lb. weight 



Fat 



0.0136 

 0.0100 



For cow weighing 1000 pounds and yielding 22 pounds of 3 per 

 cent milk : — 



For cow weighing 1000 pounds and yielding 22 pounds of 6 

 per cent milk: — 



Thus we see that even though the flow was 22 pounds in either 

 case, the food required is much greater in the case of the milk 

 rich in fat. By comparing these with the Wolff-Lehman stand- 

 ards we note that they are approximately the same, except in the 

 case of the protein. According to Haecker the protein required, 

 even in the 6 per cent milk, is much less than that called for in. 

 the Wolff-Lehman standard.
