FOODS FROM BY-PRODUCTS' 2QI 



say of 6 and 15 months, the whole milk ration may con- 

 tinue for say two or three weeks longer. It may then be 

 gradually changed to skim milk, taking two to three 

 weeks to make the transition. It is made by withholding 

 new milk in gradually increasing quantities until none 

 is given, and by increasing the quantity of skim milk fed 

 in due proportion. When the animals are reared for 

 producing dairy products, whole milk is sometimes fed 

 for a period not to exceed one week before beginning 

 to feed skim milk, and frequently not more than one 

 week is occupied in making the change from all new milk 

 to all skim milk. In more instances, however, the period 

 of transition covers two weeks. When the animals are 

 to be grown for meat and finished when approaching ma- 

 turity, it may frequently be profitable to feed all new 

 milk for say three weeks, and to make the period of 

 change to extend over two or three weeks more. Habit 

 in digestion is usually influenced at an early age. 



The earlier the animal is to be disposed of when 

 reared chiefly on skim milk during the milk period, the 

 more should the habit of fat production be encouraged 

 by feeding new milk and vice versa. When grown for 

 the dairy, muscular development is sought rather than 

 fat, hence no more whole milk should be fed than is nec- 

 essary to start the calves aright in the way of correct de- 

 velopment. 



The duration for feeding whole milk should be de- 

 termined largely by the inherent stamina of the anirrjal. 

 It is greatly important in the development of both ani- 

 mals and plants, that growth at the first shall start vig- 

 orously. Should the digestion become impaired at an 

 early age, satisfactory development subsequently sel- 

 dom follows. Whole milk, therefore, should be fed for a 

 period sufficiently long and enough of it should be fed to 

 insure to the young animal a vigorous start. 



The amount to feed will depend on the capacity of 

 the animal to take the food, on its age, and on the extent
