crease of 1.08 pounds daily per head, while turnips gave only .96 

 pounds, showing that whey had a higher feeding value, pound 

 for pound, than turnips. (320) 



902. Grain compared with blood bread. — Blood bread prepared 

 from blood and barley meal, baked in an oven the same as ordi- 

 nary bread, was compared^ with grain in two trials with 40 

 animals, lasting 138 and 120 days, respectively. Four lots of 

 pigs were fed grain and four lots blood bread. Two lots in each 

 trial received skim milk and two whey in addition to the con- 

 centrated feed. The residts are as follows: 



Results of feeding blood bread in comparison with grain — Copenhagen

The blood bread contained more water than was supposed when 

 the experiments were started. Its average percentage chemical 

 composition was as follows: 



Water, 59.6; protein, 20; starch, 16.1; fat, .4; cellulose, 2.4; ash, 1.5. 



The trials showed the blood bread decidedly inferior to rye 

 or barley when fed in connection with skim milk or whey. It 

 was concluded that had it contained less water different results 

 might have been secured. It is possible, however, that baking 

 the bread may have lowered its feeding value for pigs, the same as
