Feeds and Feeding. 



The table shows that when fed with corn 0.3 lb. tankage produced 

 slightly larger and more economical gains for feed consumed than 

 twice as much linseed meal. 



Tankage compared with linseed meal as supplements to corn. 



890. Tankage for pigs following corn-fed steers. — At the Ohio 

 Station^ Carmichael placed one 108-lb. pig with each 2 steers fatten- 

 ing on a ration composed mostly of corn. The corn voided by the 

 steers was ample for the pigs, not all being consumed. Half of the 

 pigs were each given one-third of a pound of tankage daily. The 

 pigs on droppings alone gained 1 lb. each daily, and those getting 

 tankage in addition, 1.5 lbs. For each 100 lbs. of tankage fed, the 

 pigs made 162 lbs. of extra gain. 



891. Blood meal v. skim milk. — In experiments at the Virginia 

 Station^ Quick and Spencer found blood meal and skim milk about 

 equal in value as supplements to corn, when fed on the basis of equal 

 pounds of protein. Blood meal at $3 per 100 lbs. was as valuable 

 as skim milk at 25 cents per 100 lbs. It was found necessary to mix 

 blood meal with about its own weight of wheat middlings in order 

 that the pigs would relish it. 



892. Ground bone.— At the Nebraska Station^ during each of 2 

 years Burnett fed 4 lots, each of four 79-lb. pigs, for 137 days to 

 determine the value of wheat shorts, tankage, and steamed ground 

 bone as supplements to corn meal. The breaking strength of the 

 right and left femur, tibia, humerus, radius, and ulna of the legs 

 of each pig was determined at the close of the trial. During the 

 first 5 weeks of the first trial and the first 12 weeks of the second, 

 all lots were on alfalfa pasture.
