full opportunity is offered for selecting those 

 which give promise of producing the particular 

 results desired in any given case. Animals 

 which are used continuously at hard work 

 require a wide or carbonaceous ration to sup- 

 ply energy. Young animals do best on a narrow 

 or nitrogenous ration. Milch cows do best on 

 intermediate rations. Cold stables imply a wide 

 ration ; warm stables, narrow rations. The food 

 of young herbivorous animals, of those that 

 work, and of cows in milk, may be made up of 

 about one pound of grains or other concentrated 

 foods to three pounds of roughage. 



509. The amount of the ration and the time 

 of feeding should be governed according to the 

 character and habits of the animal. Horses 

 should be fed more often than cattle and 

 sheep, since their stomachs are relatively small. 

 Horses are inclined to eat at night. Cattle, 

 sheep and swine seldom eat after dark. 



510. The ration for any one meal should not 

 be so liberal as to injure the appetite for the 

 one that follows. Regularity in time of feeding, 

 and skill in presenting the food in an appetizing 

 form, are prime factors of success.
