VELVET BEAN FEED FOR FARM STOCK. 71 



In case of the velvet bean ration 100 pounds of dry matter produced 130 

 pounds of milk, and in case of the wheat bran i;p,tion, 125 pounds. 



It seems evident, therefore, on the basis of digestibihty and feeding 

 experiments with dairy cows, that the velvet bean feed is somewhat su- 

 perior as a dairy feed to wheat bran. 



E. Velvet Bean Feed for Pigs. 



Observations with two lots of pigs were made, the first in 1918 and the 

 second in 1919. 



Experiment I. — August 12-Noveniber 20. 



Six pigs having reached a weight of about 50 pounds each were divided 

 into tlrree lots of two each, and fed on the following rations : • — ■ 



Lot I. — Mixture by weight of 80 parts corn feed meal, 10 parts alfalfa 

 meal and 10 parts digester tankage. 



Lot II. — Mixture by weight of 50 parts corn feed meal, 40 parts velvet 

 bean feed and 10 parts alfalfa meal. 



Lot III. — Mixture by weight of 50 parts corn feed meal and 50 parts 

 velvet bean feed. 



The mixture fed to Lot I was considered a standard or check ration. 

 That fed to Lots II and III was intended to demonstrate the efficacy of 

 velvet bean feed in place of the tankage. Alfalfa was used in one ration 

 and omitted in one to note if it aided, because of its "vitamine" content, 

 in promoting growth. 



Method of Feeding. — Ten ounces of each mixture were added to each 

 quart of water to satisfy appetite. The grain mixture was at first mixed 

 with a little cold water to convert it into a paste, then very hot water 

 added, and the slop fed milk warm. The pigs were fed tliree times daily. ^ 



Housing. — Each lot of pigs was kept in an outdoor pen, protected from 

 rain and sun, and given the run of a small yard. 



Weighing. — Each pig was weighed weekly on Monday morning before 

 feeding. 



> An ash mixture composed of 20 per cent salt, 40 per cent rock phosphate, 10 per cent ground 

 limestone and 30 per cent wood ashes '-'as kept constantly before the pigs in all of the experiments 

 here described. The pigs also had access to charcoal.
