138 SOUTHERN PORK PRODUCTION 



30 bushels can be secured. It is superior to cowpeas not 

 only in yield, but the seeds ripen in such a way that the 

 crop can be saved without hand picking, as is necessary 

 in the case of cowpeas. The seeds are quite digestible, 

 and it is not necessary to grind them. Their digestible 

 protein content is quite high, being about 30 per cent, 

 while the digestible carbohydrates run around 25 and the 

 digestible fats from 12 to 15 per cent, with a nutritive 

 ratio between 1 : 1.5 and 1 : 2. Their strong nitrogenous 

 nature suggests their use in connection with such carbo- 

 naceous feeds as chufas, sweet potatoes, sacharrine and 

 non-sacharrinc sorghums, corn, and possibly molasses. 



Bur clover pasture. — This valuable annual winter 

 legume thrives on any soil where Bermuda does well, and 

 is largely confined to that area. It is best to seed it 

 broadcast in July. It can then be pastured from Febru- 

 ary to ]\Iay. Its great value, too, comes in the fact that 

 it can be grown in with Bermuda, as their growing or 

 active dates do not interfere, and by the use of Bermuda 

 and bur clover it is possible to have a valuable permanent 

 pasture through the entire year. Even in cultivated 

 ground it does not require reseeding when properly 

 handled. Being a legume, it is naturally of a nitrogenous 

 nature. Henry and Morrison' give the per cent of digest- 

 ible crude protein at 3.4, that of digestible carbohydrate 

 at 8.2 and that of digestible fat at 1.1, and with a nutri- 

 tive ratio of 1 : 3.1. This suggests using with it such 

 carbohydrate feeds as chufa pasture or corn, about the 

 only highly carbohydrate concentrate feeds available at 

 this season of the year. The value of this crop is three-
