DESCRIPTION OF FEED STUFFS 



stock, but its great value is to use it as a supplement with 

 other feeds. Milk is a great appetizer and its use will in- 

 crease the amount of feed consumed materially. It also 

 serves as a regulator of the chickens' digestive system, and 

 keeps them in the best of condition. Milk will entirely 

 take the place of green feed in a ration both for chickens 

 being fattened under confined conditions, and for laying 

 hens. Growing chicks to do well need a good grass range 

 for green feed and exercise even when milk is fed. But- 

 termilk is sometimes diluted with water at the creameries 

 and in some cases is kept in dirty containers making it 

 necessary to watch the quality of the product in buying 

 this material. Whey is produced in making cheese and 

 contains the milk sugar, the albumin and most of the ash 

 contained in whole milk. It is high in water and contains 

 only about 6.5 per cent of dry matter compared with about 

 9 per cent of dry matter in buttermilk. Whey contains 

 4.8 per cent milk sugar, 0.3 per cent fat and only 0.8 

 of one per cent protein. Hence is not nearly so good a 

 food as skim or buttermilk, furnishing far less protein 

 than those products. It has about half the value of skim 

 milk as a feed for hogs and probably a similar relative 

 value for poultry, although n6 experiments have ever been 

 carried on with poultry to determine the actual food value 

 of whey. As skim milk and buttermilk secured from 

 creameries are subject to infection with the germs of 

 bovine tuberculosis it is advisable, wherever possible, to 

 get this product from creameries where the milk has been 

 pasteurized.
