FEEDING STANDARDS 

 A feeding standard is a statement of the amount of digestible 

 nutrients required by an animal over a certain period of time for 

 a given purpose, such as milk production, growth, etc. Several 

 investigators have worked out feeding standards for the various 

 classes of animals. We reproiuce here in Table II the feeding 

 standard for a dairy cow worked out by Professor F. B. Morrison 

 of the University of Wisconsin, as published in " Feeds and Feeding," 

 previously mentioned.

*Cows producing 1 lb. of fat daily should receive about 21 to 25 pounds dry matter per 1000 

 pounds live weight. 



In Table II the figures give the amount of nutrients required 

 for a 24-hour period. In the first place, it is noted that a certain 

 amount is required for maintenance. Figures are given for a 1000- 

 pound cow. The requirements for other weights are proportional. 

 An 800-pound cow would require only eight-tenths as much. 

 Next, a certain amount of nutrients is added according to the 

 amount and richness of the milk. 



These figures are the same no matter what the weight of the cow. 

 In stating certain limits, instead of an absolute requirement for 

 each unit of production, Professor Morrison gives an opportunity 

 for choice according to feed costs. He states that feeding the upper 

 limits of protein and total digestible nutrients will usually increase
