176 SCIENTIFIC FEEDING OF ANIMALS 



dry matter which they contain; the daily rations 

 given above may be reduced by about one-half. 

 Carrots are valued for the effect which they have on 

 the general health, and they are said to be a pre- 

 ventative of glanders, intestinal worms, inflamma- 

 tion of the digestive organs, as well as being useful 

 against the heating action of the food when a change 

 is made to winter feeding. Horses should not be 

 given more than 20 lbs. of sliced carrots per head 

 per day, dairy cattle up to 60 lbs., fattening bullocks 

 up to 80 lbs., and young animals a less proportion. 

 They may form one of the chief articles of diet for 

 pigs, and should be given either cooked or steamed. 

 Kohl-rabi is fed much in the same quantities as 

 carrots, but it is best to restrict the daily ration of 

 the dairy cow to 20-30 lbs., for otherwise the milk 

 and butter acquire the taste of the kohl-rabi. This 

 is not due to the passage of the flavouring material 

 of the food into the milk in the body, but to the 

 action of bacteria which are present on the kohl- 

 rabi, and get into the milk during milking. 



If the milking is done in a clean place where the 

 animals have not been fed, and if the cows are kept 

 clean, this objection to the otherwise excellent food 

 is removed, and larger quantities may be fed. 



Turnips contain the most water of all roots, and 

 should only be used as a subsidiary food for cows, 

 fattening cattle, and pigs. In the case of dairy 

 cows not more than 20-25 lbs. should be given, for
