170 EXPERIMENTAL FARMS 



9-10 EDWARD VII., A. 1910 



several qualities on the market, the better brands containing from 35 per cent to 40 

 per cent protein and some 10 per cent oil. Examples of inferior quality are not want- 

 ing, however, that run as low as 23 per cent protein and 5 per cent oil, due to the large 

 proportion of cotton seed hulls present. High grade meals are bright yellow and free 

 from hull, inferior brands are dark in colour and show coarse fragments of hull. 



vSamples Nos. 23 and 24, from shipments from Barbadoes, are of inferior quality. 

 Their protein is scarcely more than half that in genuine cotton seed meal and, further, 

 they are very poor in oil and altogether too high in fibre. 



jSTos. 25 and 26 are first-class genuine meals, the latter being somewhat the better 

 of the two. No. 27, though of good quality, is not equal in protein to the very best 

 brands. 



MLSCELLANEOUS. 



MouUe (No. 28). — This is a product of the Canada Linseed Oil Mills, Montreal, 

 composed chiefly of the ground cleanings of the flax shipments. Its constitution will 

 necessarily alter somewhat with the condition of the flax seed as received at the mills, 

 the cleaner the seed, the better the quality of the feed. For furnishing the nitrogenous 

 part of the ration it would, we think, be decidedly inferior to bran, the protein being 

 some 3 per cent less and in all probability not so digestible. The percentage of fat or 

 oil is comparatively high, evidently due to the flax seed present. This large propor- 

 tion of fat is, ixndoubtedly, the chief feature in favour of this material. The fibre is 

 decidedly high (from fragments of hay, straw, &c., present), and this fact detracts 

 from the value of the feed as a concentrate. 



Elevator Products. — Nos. 29, 30 and 31 are from the Canadian Pacific Railway 

 Elevators at Port Arthur, Ontario (Joseph G. King & Company, Lessees). For 

 several years past analyses of these waste materials have been made (ground weed 

 seeds, cleanings, &c.) with a view of determining their nutritive value, the data being 

 published in the annual reports of this Division. The output of such refuse or screen- 

 ings must be very large, and there seems no good reason, provided the material is 

 palatable and the grinding has been sufficiently fine to prevent all possibility of weed 

 seeds growing, why it should not be sold as feed. One feature in connection with 

 such feeds appears to be the difficulty in keeping the meal uniform as to feeding 

 value, owing to variableness in the nature of the refuse accompanying the grain. 

 Great differences in composition are found among weed seeds, and consequently the 

 percentages of protein and of fat of the resulting feed will be notably affected by the 

 kind of weed seed predominating in the screenings. 



No, 29. Fine Flax Screenings. — Though not quite so rich in oil as similar 

 material forwarded the year previous, it is still very high in this constituent, viz., 18 

 per cent. It is also rich in protein, so that the feed would rank among the best feed- 

 ing stuffs. No doubt these good qualities are dvie to the large amount of broken flax 

 seed present. 



No. 30. Small Seeds from }Yheat. — Compared with No. 29, it is decidedly poorer 

 in oil, slightly lower in protein and contains more fibre. 



No. 31. Wheat and Flax Screenings. — A material of fair feeding value, but dis- 

 tinctly inferior to Nos. 29 and 30, as evinced by its lower protein and fat. 



No. 32. Cypher's- Daniel Egg Mash. — This contains a considerable percentage of 

 protein — the nutrient more especially necessary for egg production — but is not rich in 

 fats or phosphates. 



Upon its condimental or medicinal properties we are unable to pronounce, but 

 considered simply from the nutritive standpoint the price quoted ($2.75 per 100 lbs. 

 f.o.b. Toronto) would appear to be too high. We consider that a ration of equal feed- 

 ing value could readily be compounded from materials ui^on the market at much less 

 cost.
