Poultry Feeds. 



Massachusetts has a large poultry industry, and a great variety of 

 feed stufifs are offered ; the number of brands in the market shows 

 steady increase from year to year. 



Meat scraps are relatively coarse dry material of 



Animal varying proportions of flesh, bone and fat. During 



By-Products. the summer months lots of tainted scraps are fre-

bright, clean goods, free from taint, ground neither 

 too coarse nor too fine, possessing a high protein content (50 per 

 cent) a moderate amount of ash (20 per cent) and not over 15 per 

 cent of fat. The 16 samples reported have been divided into first 

 grade, — those testing 45 per cent protein or above — and second 

 grade, — those testing below 45 per cent protein. The 12 first grade 

 scraps averaged 51.07 protein, 15.29 fat and 22.43 ^sh, and the 

 average retail price was $2.53 a hundred. The second grade scraps 

 averaged 41.09 protein, 14.47 ^^^ and 33.54 ash ; the average retail 

 price was $2.40 a hundred. These scraps contained more bone and 

 less meat than the first grade. The station cannot recommend any 

 particular brand. Buyers are advised to study the analyses given on 

 pages 26-27, to note the odor and mechanical condition of the goods, 

 and to purchase accordingly. 



Meat and bone meals are not so freely offered as meat scraps. 

 They are dry, finely ground, contain less meat and fat and noticeably 

 more ash than do the scraps. To be of first grade, they should con- 

 tain 40 per cent protein, 10 per cent fat, 40 per cent ash, and be 

 free from bad odor. They are worth in the vicinity of 20 per cent 

 less than first grade scraps. The 9 samples reported have been 

 divided into first and second grades, depending upon the protein per 

 cent. 



Bone meals, a few samples of which were collected, have been 

 made from either kettle rendered bone, or from bone steamed under 

 pressure. The latter contains rather less protein and can be sold at 

 a little lower price. Two samples collected fell decidedly below 

 their guarantees.
