particularly valuable for supplying to tlie animal systera tliat nutrient (protein) ra- 

 quired alike for egg and flesh production, and which is not found to any large degree in 

 most grains. Moreover, the use of a ration composed exclusively of grain is very apt 

 to lead to an excessive deposition of fatty tissue — and this is undesirable in both lay- 

 ing and fattening stock. The recognition of this has led in recent years to the mix- 

 ing of a certain amount (usually about one-eighth) of these meat meals with the grain 

 portion of the ration, and this practice has been followed by most gratifying results, 

 especially during winter, and in the summer when the fowls can only be allowed a 

 very small run. Further, the products of the packing house are frequently rich in 

 bone, which, as most poultrymen know, is, when fresh and untainted, one of the best 

 foods for laying hens.* 



There are several brands upon the market, varying in price and in quality, and 

 inriuiries are being constantly received as to their respective valiies to the poultr'.' 

 feeder. We have accordingly submitted to analysis such of these as are being used 

 by, or could be procured by Mr. Gilbert, Poultry Manager, Central Experimental 

 Farm. They comprise: — 



Beef Scrap No. 1, Cyphers Incubator Co., Buffalo. 



Beef Scrap No. 2, Cyphers Incubator Co., Buffalo. 



Darling's Beef Scrap " " 



Superior Meat Meal, W. A. Freeman Co., Ltd., Hcimilton, Ont. 



Meat Meal, A. J. Morgan, London, Ont. 



Of Beef Scrap No. 1, two samples were examined, obtained a month apart and 

 from different sources.

Moisture. — Meat meals by reason of their high nitrogen content are. if at all 

 moist, very susceptible to change of a deleterious character, to become tainted and in- 

 fested with mites, &c. The drier a meal is the better it will keep. It is advisable for 

 poultrymen to examine critically any meat meal they may be purchasing; it should 

 be sound and dry. Examination with a pocket lens is necessary to detect insect life, 

 which, if present, indicates a certain degree of decay. 



With the exception of one of the samples of Beef Scrap No. 1, all are excellent 

 as regards moisture-content. The sample referred to, it is only right to say, was not 

 obtained directly from the manufacturer and may have absorbed moisture through 

 undue exposure- 

 Protein.— This is the most important of the nutrients, and provided the meal 

 is sound and the sourcme of the protein wholesome and digestible, the value of a meal 

 should be very largely regialated by tlie percentage present.
