326 MAINE AGRICULTURAL EXPERIMENT STATION. I9IO. 



NaOH could be used in place of the i-io normal piperidine 

 and give practically the same results. Comparisons of several 

 samples of feces were made using the two solutions with the 

 following results : — 



Titration with Piperidine 



1 1. 6 per cent uric acid 



7.35 per cent uric acid 



10.80 per cent uric acid 



8.91 per cent uric acid

Foods Experimented With. 



Such feeds were selected as are most commonly used for 

 poultry foods in this country. Probably no other one grain 

 is so universally fed east of the Rocky Mountains as corn in 

 some form or other and there seems to be no other grain so well 

 relished by the birds. In some sections, particularly on the 

 Pacific Coast, wheat largely replaces corn. In other sections 

 oats and buckwheat or India wheat form an important part of 

 the ration. In the mashes, particularly the dry mashes so- 

 called, wheat bran forms an important part, often as much as 

 50 per cent, consequently this material was included in the test 

 and several dry mash mixtures such as are usually fed. 



Beef scraps. Best quality found in the market. 



Bran, wheat. The coarses variety from spring wheat. 



Corn, whole. No. 2 yellow, picked over and cleaned. 



Corn, cracked. From No. 2 yellow, screened. 



Corn meal. From No. 2 yellow corn. 



Clover, cut. From second crop, just beginning to blossom. 



India wheat. Fair quality, picked over and cleaned. 



Oats. Best Western clipped oats, carefully picked over. 



Oats, rolled. One of the best table varieties. 



Wheat, hard. A variety of hard wheat sold as "hen wheat." 



Wheat, soft. A seed wheat, rather soft, large, plump grain. 



Dry mash mixtures : — 



No. I. 3000 grams bran 



1125 grams corn meal 

 1125 grams gluten feed 

 600 grams beef scrap.
