3i4 POULTRY PRODUCTION 



Meat scrap is the most generally used source of animal 

 protein there is, though it is being somewhat (lisi)laced in 

 some sections b.y the use of milk and milk by-products. 



Stewart and Atwood re])ort 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 Ijeef scrap laid 386 eggs in 120 days; the ones 

 recei\'ing milk albumin laid 228 eggs during the same period, 

 while the hens recei\'ing 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 recei\'ed beef scrap, and 

 the fresh-meat pen recei\ed 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 

 receixing 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 ecpialize the amount of protein contained in the meat 

 sera]) 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 feed of any kind was given. As the result of two 

 years' work, tlie follo\\ing average egg production was 

 secured:

Skim-milk pen . 133.5 " 



No animal-fi'ed pen . . , , 36.0 " 



He further found- tliat meat scrap at S2.5() a hundred 

 jiounds was slightly cheajier than skim milk at 3(1 cents a 

 hundred pounds when fed to Leghorns.
