a saving of 43 per ct. in the amount of grain for 100 Ibs. of gain,

896. Feeding corn on alfalfa pasture. Snyder of the Nebraska 

 Station 1 grazed 3 lots of 47-lb. pigs on alfalfa pasture during each 

 of 2 summers. One lot received a light, the second a medium, and 

 the third a full allowance of shelled corn. The combined results 

 of the trials, lasting 98 and 119 days respectively, are averaged 

 below :

It is shown that Lot I, fed a light grain allowance on alfalfa 

 pasture, required only 39 per ct. as much grain for 100 Ibs. gain as 

 Lot III, fed a full corn allowance. Lot III, however, made twice 

 as rapid gains as Lot I. Snyder concludes that a light grain al- 

 lowance on alfalfa pasture is not economical for growing pigs unless 

 alfalfa is abundant, grain high in price, and market conditions war- 

 rant holding the pigs. It is usually more profitable to feed 2 Ibs. 

 or more of corn per 100 Ibs. of pigs than to feed a lighter ration. 

 Cottrell of the Colorado Station 2 states that alfalfa makes the best 

 hog pasture, and that hogs fed some grain daily will make from 500 

 to 1,000 Ibs. of gain during the pasture season from an acre of good 

 alfalfa, after deducting the gain which the grain would make if 

 fed alone. 



897. Cowpea pasture. Duggar of the Alabama Station 3 placed 

 three 50-lb. pigs in a field of cowpeas, giving corn additional, while 

 a second lot was fed corn only. The trial lasted 42 days with the 

 results shown in the table:
