THE FEEDS. 345 



Stewart and Atwood report that when the same amount of 

 protein was furnished by beef scrap, milk albumin, and fresh 

 meat scrap, respectively, to three pens of twenty White 

 Leghorns each, ten of which were pullets and ten hens, the 

 hens receiving beef scrap laid 386 eggs in 120 days; the ones 

 receiving milk albumin laid 228 eggs during the same period, 

 while the hens receiving the fresh meat and ground bone 

 laid 279 eggs. 



This test began November 1, and at the end of 120 days 

 the pens were shifted so that the beef-scrap pen received the 

 fresh meat, the milk-albumin pen received beef scrap, and 

 the fresh-meat pen received milk albumin. During the 120- 

 day period following, the pen receiving fresh meat laid 947 

 eggs, the one receiving beef scrap 987 eggs, while the one 

 receiving milk albumin laid 935 eggs. 



Philips' reports results in which three pens of Leghorns 

 were fed corn, wheat, oats, bran, and shorts in the same 

 proportion. To the ration of pen No. 1 was added 10 per 

 cent, meat scraps. To pen No. 2 was added enough skim milk 

 to equalize the amount of protein contained in the meat 

 scrap of pen No. 1. He makes note of the fact that this was 

 about all the milk the chickens would drink. In pen No. 3 

 no animal food of any kind was given. As the result of two 

 years' work, the following average egg production was 

 secured: 



Meat-scrap pen 135 . eggs 



Skim-milk pen . . . 133.5 " 



No animal-food pen . . . ... 36.0 " 



He further found^ that meat scrap at $2.50 a hundred 

 pounds was slightly cheaper than skim milk at 30 cents a 

 hundred pounds when fed to Leghorns. 



It is sometimes claimed that liberal feeding of meat scrap 

 injures the fertility of eggs, but so far no definite data on the 

 matter has found its way into experimental reports. 



The amounts of digestible nutrients found in 100 pounds 

 of meat scrap of good quality, as determined by digestion
