III. Poultry Feeds. 



Of the several animal by-products available for poul- 

 Animal By- try feeding, meat scraps and meat and bone meal are 

 Products, the most prominent. Bone meal, dry ground fish and 

 Pages 26-28. granulated milk are occasionally offered. 



Aleat scraps are a relatively coarse, dry material, of 

 varying proportions of flesh, bone and fat. Preference should be 

 given to bright, clean, finely ground brands of a high protein content 

 (50 per cent), small amounts of bone (ash) and a low percentage of 

 fat (15 per cent). Scraps, free from taint, are one of the most satis- 

 factory animal foods for poultry. The average retail price of the 

 different lots sampled was about $2.50 a hundred. 



Meat and hone meals are not as widely distributed as meat scraps 

 and appear chiefly as a few standard brands. They are dry, finely 

 ground products, averaging lower in protein and fat, and decidedly 

 higher in bone (ash) than scraps. A good grade should contain 40- 

 per cent of protein, 10 per cent of fat and 35 per cent of ash. The 

 retail price, $2.25 a hundred, was rather high as compared with-, 

 scraps. 



Fish. Dry ground fish resembles the better grades of animal meal 

 in protein content (40-45 per cent) but contains rather more bone 

 (ash), a very little fat (1-2 per cent) and has a somewhat lower feed- 

 ing value. 



Granulated milk. There was very little so-called granulated milk 

 on the market. The two lots sampled tested similar to animal meal 

 and had probably an equal feeding value. 



There are three distinct classes of these mixtures, 



Poultry Mix- the ground products, meals or mashes, to be fed wet 



tures. Pages or dry ; the finely cracked grains and seeds for 



29-32. chick feeding; and the whole grains and large seeds 



for mature fowls. 

 The meals and mashes are composed chiefly of corn, oats and 

 wheat or wheat offal, fortified with some animal by-product, and 

 lightened with ground alfalfa, clover, hay or breakfast food waste. 

 To this is often added charcoal as an anti-ferment, and more or less 

 grit or shells. Ash determinations readily show the presence of any 

 appreciable amount of grit or shells and have discouraged their use 

 as a filler. Barley, rj'e, linseed and cottonseed, millet seed, peanut
