cts. ; lot 4 on linseed oil cake gained 1.14 lbs., at a cost of 3.7 cts. ; and lot 5 on 

 peanut oil meal gained 1.11 lbs., at a cost of 3.5 cts. 



In tbese experiments cotton.seed meal, fed in proportion of 13.5 per cent of 

 the ration, proved safe and gave the most economical gains. Linseed meal was 

 practically equal to cottonseed meal. Peanut meal, while low in gains, showed 

 up well in cost, due to the small amount necessary on a protein basis. Gluten 

 meal compared closely with corn meal. Fish meal, while palatable, caused 

 intestinal disturbances even though fed as only one-tenth of the meal ration. 



In Manitoba, barley is the accepted standard feed for pig fattening. An ex- 

 periment was carried out at Brandon to test the desirability of mixing other 

 feeds with it. Four lots of pigs were used. Lot 1. containing 5 pigs, was fed 

 barley; lot 2, 5 pigs, barley and feed flour, 3: 1; lot 3, 4 pigs, barley and shorts, 

 3:1; and lot 4, 4 pigs, barley and oats in equal parts. In addition each animal 

 in all lots was fed about 0.4 lb. of tankage daily. 



Lot 1 made an average daily gain per head of 1.11 lbs. at a cost of 4.44 cts. 

 per pound of gain ; lot 2 a daily gain of 1.07 lbs. at a cost of 5.07 cts. ; lot 3 a 

 daily gain of 0.99 lb. at a cost of 5.08 cts. ; and lot 4 a daily gain of 0.86 lb. 

 at a cost of 6.18 cts. The previous year barley and feed flour had given the 

 best results. In both years the barley and oats mixture was the most ex- 

 pensive and least satisfactory. 



As skim milk is not usually available on Manitoba farms, an experiment 

 was also undertaken at Brandon to find a succulent feed for young pigs to be 

 used as a substitute. Mangels and potatoes, both raw and cooked, were tried, 

 being fed A^ath barley chop and shorts. The raw feeds were valued at $3 per 

 ton and the cooked at $5. The cooked potatoes gave the best results both in 

 gains and costs, while the raw potatoes were least satisfactory. The cooked 

 mangels gave better results than the raw but not enough to pay for the cooking. 



In another experiment raw and cooked mangels were compared with a 

 straight grain ration. The raw mangels were about equally successful with 

 the grain and better than the cooked mangels. The successful use of the raw 

 mangels compared with grain apparently depends upon the cost. 



At the Lacombe station, Alta, three lots of 5 pigs each, after being weaned 

 at about 10 weeks of age, were fed 30 days on shorts and milk, shorts, and 

 wheat. Those on shorts and milk gained 0.786 lb. each daily, at a cost of 

 3.71 cts. per pound of gain ; those on shorts 0.42 lb., at a cost of 4.71 cts. ; and 

 those on wheat gained 0.373 lb., at a cost of 3.21 cts. These results are based 

 on milk at 20 cts., shorts at $1.65, and wheat at $1 per 100 lbs. 



Another experiment was carried out to test the value of different pastures 

 in pork production. A basic ration of shorts, wheat, and skim milk was fed 

 at the values quoted in the previous experiment to seven lots of 5 pigs each on 

 difljerent kinds of pasture and in a dry pen. The lot on pasture made up of 

 wheat, oats, and barley made an average daily gain of O.SOS lb. per head 

 at a cost of 3.5 cts. per pound to produce, on alfalfa pasture 0.808 lb. at a cost 

 of 3.4 cts., on rape 0.778 lb. at a cost of 3.45 cts., on oats 0.795 at 3.41 cts., on 

 barley 0.762 lb. at 3.51 cts., on wheat 0.661 lb. at 4 cts., while those in the corral 

 gained 0.501 lb. daily at a cost of 5.3 cts. 



Bations for pig's at weaning time, L. A. Weaves {Missouri Sta. Bid. .151 

 {1911), p. 29). — Sixty-four pigs averaging 40 lbs. each were divided into eight 

 lots, seven of which were pastured on rape and one on blue grass They were 

 fed different additional rations. 



From the results of the experiment during 112 days there was found little 

 difference in the efficiency of the following rations: (1) Corn, snorts, bran, 

 and tankage (4:4:1:1), (2) corn, shorts, and tankage (6:3:1). and (3) 

 corn and tankage (9:1). Corn alone was not a well-balanced ration. Corn
