by the other groups. Considering both the rate and cost of gain the skim milk and 

 meal ration was rated highest, and the ration containing a large amount of blood 

 meal with meal lowest. 



" Blood meal, mainly on account of its extra cost, proved the least satisfactory of 

 these supplemental foods. Tankage proved much more satisfactory and, while not 

 quite equal to skim milk, yet, when fed in small quantities along with a small 

 quantity of skim milk, gave about the best results." 



"Judging from this, we would say that tankage would prove itself an excellent 

 food to add to a ration for pigs when only a limited amount of skim milk was avail- 

 able, which is often the case on the average farm. In both cases where tankage and 

 blood meal were fed in different proportions, the smaller proportion proved more 

 satisfactory. This is about what we would expect in considering the nature of the 

 main meal ration, viz, middlings, barley, and oats. Had the ration consisted of a 

 large amount of corn, it is very likely that the larger amount of these by-products 

 would have proved more satisfactory." 



In a test of the value of pasturage, two lots of 12 pigs were pastured for five weeks 

 on clover and then for ten w r eeks on rape — one lot being fed all the grain they would 

 eat up clean and the other about two-thirds as much. After the period on pasture, 

 both lots were fed in pens for seven weeks on roots and a full meal ration. The total 

 gains made during the test as a whole by the lot on a heavy ration was 1,334 lbs., and 

 and by those fed a light ration, 1,339 lbs. While on pasturage, the two lots required 

 respectively 4.21 and 3.53 lbs. of meal per pound of gain. Considering the test as a 

 whole, the amounts required were 5.17 and 4.45 lbs. and the cost of meal per pound 

 of gain 4.65 cts. and 4 cts. 



"The importance of carefully husbanding the grain fed to pigs on pasture is 

 strongly emphasized in this experiment. At the time the pigs went inside, the light 

 feed ones were considerably thinner than the heavy ones, but they had developed 

 just as big frames and went ahead more rapidly during the last stages of feeding, at 

 which time they, too, were fed a full ration." 



Soy beans and rape were compared with two lots of 6 pigs each, fed like rations of 

 meal and skim milk in addition to the green feed. About 5 lbs, of soy beans and 

 about 5.5 lbs. of rape was eaten per head per day. In the five weeks of the test, the 

 total gain on rape was 145 lbs. and on soy beans 159 lbs. 



" It is evident that the soy beans are a richer food than rape, a lesser quantity pro- 

 ducing a greater gain. On the other hand, rape is a heavier yielder per acre than 

 soy beans. From this it is evident that, for purposes of feeding green forage to pigs 

 in pens, a given amount of land might be equally profitably sown with either soy 

 beans or rape. When, however, it is desired to pasture pigs on one or the other 

 crop, rape will stand the tramping, etc., much better, and is the more profitable 

 crop." 



Canadian and Danish bacon, G. E. Day (Ann. Rpt. Ontario Agr. Col and Expt. 

 Farm, 30 (1904), PP- 89-96).— On the basis of personal observations, the author dis- 

 cussed the market qualities of Danish and Canadian bacon with a view to suggesting 

 methods of improving the Canadian product. The Danish bacon is of superior qual- 

 ity and the bulk of it comes from crossbred pigs fed largely on barley though other 

 grains including corn are sometimes used. The pigs are not given any considerable 

 amount of exercise. 



Some notes are given regarding the crops raised at the Ontario Experimental Farm 

 and also regarding the feeding of cattle and pigs and experiments with live stock. 

 The work with pigs has been summarized in another publication (E. S. R., 15, p. 69).
