Feeds; Animal nutrition. 260 FEEDS AND FEEDING, ABRIDGED from 10 to 12 lbs. of expensive concentrates daily to secure a reason- able flow of milk. Cows should be fed individually.—Even when fed liberally, cows of marked dairy temperament rarely lay on flesh when in full flow of milk, provided their ration is well balanced. But cows of ordi- nary capacity may easily be over- fed, in which case they lay on fat instead of increasing their milk production. Since even in well- bred and well-selected herds the different cows vary widely in pro- ductive ability, to secure the most profit they must be fed as individ- uals, instead of giving both high and low producers the same ration. It is not necessary, however, to compute a balanced ration for each animal. All that is needed is to determine what amounts and pro- portions of roughages and concen- trates should be used to make the most economical ration that meets the requirements for the average cows in the herd, after the man- ner shown in Chapters VII and VIII. For example, the ration on Page 110 meets the average require- ments for cows producing 30 lbs. of per ct. milk daily. In feed- ing the herd, each cow should be given all the roughage she will eat, which will usually be about 2 lbs. of dry roughage daily per 100 lbs. live weight, or 1 lb. of dry roughage and 3 lbs. of silage. Then the amount of concentrates for each cow may be determined from one of the following rules: 1. Feed 1 lb. of concentrates per day for each pound of butter fat the cow produces per week, or 2. Feed 1 lb. of concentrates per day for each 3 to 4 lbs. of milk, depending on its richness, or 3. Feed as much as the cow will pay for at the ruling prices for feeds and products, increasing the allowance gradually until she fails to respond by an increase in production
