In the table given above the cob has been deducted from the figures for corn- 

 and-cob meal, so that the actual corn is compared in all cases. 



It cost 6 cents per bushel to grind the corn-and-cob meal, and 2 cents per 

 bushel to grind corn meal. The results of the test were regarded as so conclusive 

 against corn-and-cob meal that no further tests were made. 



The Missouri Experiment Station also gives a decidedly adverse report upon 

 feeding corn-and-cob meal to hogs, but Kansas and New Hampshire report in its 

 favor. 



Gluten Meal. — The Central Experimental Farm, Canada, reports un- 

 favorably upon gluten meal as a feed for swine. J. H. Grisdale says regarding it: 

 " Gluton has been fed in limited quantities, but has not proven very satisfactory 

 for either bacon production, young pigs, or breeding stock. It seems to be rather 

 unpalatable, and produces soft bacon." 



The Cornell Station also gives an unfavorable report of this feed as compared 

 with corn when both feeds were fed with skim-milk. 



Linseed Meal. — (Oil Meal) — Linseed meal has been referred to under 

 supplementary feeds with corn. It is seldom advisable to feed linseed meal to a 

 greater extent than one-fifth of the total meal ration, and, as a rule, half this 

 quantity will be found more economical. It is highly recommended by some as a 

 feed for nursing sows, and for young pigs after weaning. The writer has had only 

 fair success in its use as a substitute for skim-milk with young pigs. 



In experiments with substitutes for skim-milk for young pigs, the Central 

 Experimental Farm, Canada, obtained an average daily gain of six-tenths of a 

 pound per pig with a mixture consisting of four parts wheat middlings and one 

 part linseed meal. It required 280 pounds of the mixture for 100 pounds of gain, 

 which is a very satisfactory showing. The linseed meal was not so satisfactory 

 as skim-milk, but gave better results than other substitutes for skim-milk tested at 

 the same time. 



Cottonseed Meal. —This very concentrated feed possesses some property 

 which renders it fatal to hogs when used in considerable quantities. A small 

 allowance per day may be fed without injurious results, but great care is necessary. 

 There does not seem to be any good reason for feeding cottonseed meal to hogs in 

 Canada. 



Oat Feed. — This by-product of the oatmeal mill sometimes has a consider- 

 able feeding value, but, owing to the fact that it often contains a large proportion 

 of oat hulls, it is not a very satisfactory feed to buy for swine. Experiments with 

 oat feed are not satisfactory, because the product is anything but constant in com- 

 position. The same remarks apply to all by-products of fhe oatmeal mills, under 

 whatever name they may be sold. 



Brewers' and Distillers' Grains. — Grisdale, of the Central Experi- 

 mental Farm, reports economical gains'frora "spirit grains" when fed in com- 

 bination with a meal ration. Generally speaking, these products are rather bulky 

 and fibrous for swine, unless used in limited quantity as a supplement to a grain 

 ration, in much the same way as alfalfa hay or roots may be used. 



Sugar-Beet Pulp. — In the wet state this product may 'be regarded as 

 similar in feeding value to roots, and may be employed in exactly the same way. 

 The dried pulp is hardly a satisfactory feed for swine.
