Value of Various Feeding Stuffs for Swine.

It will be seen that the pigs ranging in the cowpea field gained 

 nearly 3 times as fast as those getting corn alone in the dry lot. 

 The area grazed by the pigs equaled one-sixth of an acre and the 

 yield of peas was estimated at 13.2 bushels per acre. In this trial 

 the seed of the cowpeas must have furnished most of the nutri- 

 ment, and the leaves but little. (261) 



898. Soybean pasture. At the Alabama Station 1 Gray, Duggar, 

 and Ridgeway fed 2 lots, each of 6 pigs averaging 75 Ibs., for 35 

 days on the following rations to determine the value of soybean 

 pasture as a supplement to corn : 



Soybean pasture as a supplement to corn. 



The pigs on soybean pasture made 25 per ct. greater gains than 

 those fed corn alone, and required only 157 Ibs. corn for 100 Ibs. 

 of gain. In this trial 1 acre of poor soybean pasture proved equal 

 to 1,068 Ibs. of corn. When one considers the small amount of 

 corn required for 100 Ibs. of gain, the great value of the soybean 

 crop for pork production is shown. It is probable that the soy- 

 bean seeds furnished most of the nutriment supplied by the pastur- 

 age. (201) 



899. Rape v. clover pasture. At the Wisconsin Station 2 in 60-day 

 trials during each of 2 years, Carlyle hurdled one lot of 104-lb. 

 pigs on rape with access to a blue-grass pasture, while others grazed 

 in a field of second-growth clover. Both lots were fed a mixture 

 of 2 parts corn meal and 1 part shorts with the results given below :

The pigs in Lot I grazing on rape made somewhat larger daily 

 gains and required less corn for 100 Ibs. of gain than those on
