character, but it is not a badly balanced feed. The feed- 

 ing value varies greatly on account of the different stages 

 of growth at which it is fed. One hundred pounds of the 

 feed that hogs will consume on rye pasture will contain 

 from 2.5 to 8 pounds of digestible crude protein, from 13 

 to 60 pounds of digestible carbohydrate, and from a half 

 to a pound of digestible fat, with a nutritive ratio of 

 approximately 1 : 6.5. This suggests the combining with 

 it of a winter legume like vetch, which is common prac- 

 tice, and of feeding with it such nitrogenous feeds as soy 

 beans, garbage, rape, wheat by-products, and meat meal 

 or tankage. 



Wheat by-products (middlings, shorts, red dog flour). 

 — These feeds should only be resorted to when other 

 suitable protein concentrates cannot be grown on the 

 farm, for protein feeds can generally be grown more 

 cheaply than they can be bought. Of these feeds, the 

 digestible protein per 100 pounds will run from 10 to 15 

 pounds, of digestible carbohydrates about 50 pounds, and 

 the digestible fats from 3 to 5 pounds. The nutritive 

 ratios will generally run about 1 ;4.5, which suggests 

 the use of these feeds with such feeds as chufa pasture, 

 sweet potato pasture, saccharine and non-saccharine 

 sorghums, corn, and rice b}^-products. These feeds are 

 especially valuable in making slops and in enriching 

 garbage. 



Kentucky blue grass pasture. — This is a most valuable 

 winter grass, but its usefulness is confined mostly to 

 Kentuckv, Tennessee, North Georgia, North Carolina, 

 Mississippi and the northern southern states. The seed 

 are usually sown in September at the rate of about 25
