SESSIONAL PAPER No. 16 



No. 33. Bent's Milk Alhuvien No. 1. — This is described as 'skim-milk in the dry 

 form without the sugar,' and is really a by-product of the milk sugar factory. It is 

 put forward by the manufacturers — The Bent-Croissant Company, Antwerp, N.Y., 

 U.S.A. — as a concentrated food for poultry that may take the place of meat scraps 

 and animal meals. It comes in the form of a coarse granular powder, which, as far 

 as our experience shows, has excellent keeping qualities. 



Our analysis shows that it is a highly nitrogenous food — the protein-content 

 being 41-21 per cent. It should, therefore, if used judiciously, prove a valuable addi- 

 tion to the ration of both laying and fattening stock. Skim-milk has been repeatedly 

 shown to have a special value for poultry feeding; it seems, therefore, that this ' Milk 

 Albumen ' may prove a ' convenient wholesome and palatable substitute ' when fresh 

 skim-milk is not readily obtainable. 



Bent's Milk Albumen No. 2 is a product still more concentrated than the pre- 

 ceding sample analysed by us, showing 72-43 per cent protein. From what we can 

 learn, however, this brand is of more recent introduction and, consequently, experience 

 in its practical use in the poultry yard is as yet but limited. 



Kos. 35, 36 and 37. These are by-products from the Walkerville distillery and 

 may be described as follows : No. 35 is ' the dried grains from a mash composed of 

 corn, rye and barley malt,' No. 36, ' the dried grains from a pure barley malt mash,' 

 and No. 37, ' the dried grains from a rye and rye malt mash.' 



Dried distiller's grains furnish a feeding stuff of considerable value, possessing 

 a fairly high (though somewhat variable) protein-content, with a notable percentage 

 of fat. They are readily eaten by cattle and when purchased at a fair price have 

 given good returns with milch cows and fattening stock. 



That the nutritive value of this class of feeds is by no means a fixed quantity 

 is evident from the analyses of the present series — the range in protein-content being 

 from 14-38 per cent to 19-69 per cent. It is important, therefore, that the purchaser 

 should assure himself by special inquiry as to the composition of the brand or brands 

 offered him. 



No. 38. Apple pulp from Cannery. This is described as ' the refuse of apples 

 after being boiled and subjected to hydraulic pressure, the extracted juice being used 

 in the manufacture of jam and jellies.' 



It will be seen that this pomace contains in the neighbourhood of 15 per cent 

 of dry matter, of which practically one-tenth is protein. 



We should not consider that the nutritive value of this material was equal to 

 that of the ordinary farm roots or of com ensilage, but no doubt it could be used to 

 advantage, if sound, to furnish a par,t of the succulent ration of the milch cow, and 

 possibly also, to a certain extent, for other classes of farm animals. 



The manurial value of this pomace is very small — practically negligible — as will 

 be observed from the following results : —

In our report for 1906, in speaking of a sample of pomace from a cider mill, the 

 composition of which we were publishing, we cited our correspondent's opinion as to 

 its feeding value. This was to the effect that it had proved very valuable in keeping 

 up the milk flow. Commencing with a pailful of pomace per day the quantity had 

 been increased to two feeds of half a bushel each, and omitting a feed meant a 

 falling off of about IJ lbs. at the next milking. Resp)ecting the present sample, Mr. 

 Schou writes as follows: 'We waited until oin* stock of roots (turnips and carrots) 

 was finished and then used the pulp. We were pleased to find the milk did not 

 decrease at all. Two small pigs used to eat all they could find and seemed to thrive 

 on it.'
