REPORT OF THE CHEMIST 169 



SESSIONAL PAPER No. 16 



With respect to Nos. 6, 7 and 8, it may be said all were genuine and of good 

 quality. In no instance was the foreign matter (fragments of hay and straw, weed 

 seeds, hulls, &c.) present in such quantity as to materially affect the feeding value of 

 the bran. Our work on genuine brans in 1903 furnished the following limits : Pro- 

 tein, 13-25 per cent to 15-31 per cent; fat, 3-60 per cent to 5-19 per cent, and fibre, 

 9-28 per cent to 10-93 per cent. 



Bran sample No. 9 contained a very considerable proportion of oat hull and other 

 o3al, and, consequently, was of decidedly inferior quality. The analysis confirms the 

 opinion formed by inspection, for the protein is about 3 per cent lower and the fibre 

 8 per cent to 9 per cent higher, than in genuine samples. 



As a class, shorts are characterized by somewhat higher percentages of protein, 

 fat and carbohydrates and a lower percentage of fibre, than bran. Shorts, therefore, 

 should constitute the superior feed. As produced from hard wheat by the modern 

 roller process, shorts have the appearance of finely ground bran. Under the older 

 milling methods shorts or middlings were quite floury. All the samples analysed were 

 of good quality. The limits obtained in 1903 for genuine shorts were: Protein, 15-15 

 per cent to 17 per cent; fat, 3-98 per cent to 6-23 per cent, and fibre, 3-82 per cent to 

 7-51 per cent. 



OAT PRODUCTS. 



It is among the by-products of the oatmeal mills and certain breakfast food 

 factories that we find the most worthless of the feeds upon the market. As a class 

 these so-called oat feeds are decidedly low grade, being characterized by a small per- 

 centage of protein and a high fibre-content due to the large proportion of oat hulls 

 and other offal from the mills they contain. Very few of these feeds are worth the 

 price asked, but yet they appear to compete successfully with bran and other products 

 of high feeding value. 



Sample No. 14 was forwarded by a correspondent in Prince Edward Island, who 

 states that it was a product of the Tilson Company, Limited, and was invoiced at $20 

 per ton. It was found to consist essentially of oat hulls, with a protein-content of 

 2-62 per cent and fibre 32-16 per cent. These results establish its extremely low value 

 as a feeding material. 



Sample No. 15, sent by a correspondent in Haileybury, Ontario, is said to be a by- 

 product of the rolled-oat mills and known by the name of ' X ' oat feed. It was sold 

 at $20 per ton. Analysis shows only 4 12 per cent protein; the fibre-content is 31-24 

 per cent. It is in the same category as No. 14— practically valueless for use as a part 

 of the meal ration. 



PEA PRODUCTS. 



Information having reached us that much of the pea meal being sold was adul- 

 terated by an admixture of pea hulls, a number of samples were submitted to analysis. 

 Genuine pea meal is a material of high feeding value, with protein in the neighbour- 

 hood of 25 per cent and about 5 per cent fibre. It is not a feed rich in fat. Many of 

 the pea meals upon the market appear to be of inferior quality, due to the presence of 

 pea hulls. The hull or bran of the pea is an extremely poor food, containing only 5 

 per cent protein and over 50 per cent fibre. Nos. 16 and 17 are genuine pea meals. 

 No. 21 gives the composition of pea hulls and No. 22 of split peas. Nos. 17, 18 and 19 

 nre examples of commercial pea meals that contain an admixture of pea hull. 



COTTON SEED MEAL. 



Cotton seed meal is not much used in Ontario, but is largely fed in the Maritime 

 Provinces, coming by water-freight from Florida and the southern States. There are
