ANIMAL PRODUCTION. 173 



slightly increased and the cost of production lowered. The most satisfactory grain 

 mixture was shorts and linseed meal, 4:1. 



The value of a number of stock foods for pork production was tested, using 8 lots 

 of 4 pigs each, the tesl covering 90 days. The list included International Stock 

 Food, Anglo-Saxon stock Food, rlerbageum, and sugar and flax. A grain mixture 

 composed of half shorts and half oats, peas, and barley, fed in connection with skim 

 milk or pasturage, was the cheapest. All the stock feeds had the effecl of raising 

 tin- cosl "\ production. 



With Uveco, which is apparently made by passing cooked or steamed Indian con, 

 between rollers, the gain was Bomewhal larger than on shorts and oats, and the cost 

 pheaper. "The food was evidently very palatable, as the pigs ate il with avidity." 



Large Clacks have been tested as to their value for pork production for several 

 year-, with the following results: "As prolific and healthy breeding stock they can 

 not he surpassed by any of the breeds now commonly hied in Canada. As pigs for 

 pressing they an' exceedingly impressive, whether male or female, and leave then- 

 mark stamped very distinctly, no matter what the other cross maybe. The cross- 

 breds have also been uniformly healthy and quick feeders, the cross with the Tam- 

 wotth being particularly remarkable in this respect. As pure-bred pi'_ r > they have 

 been found to he rapid and easy fatteners, exceedingly good grass or pasture pigs, 

 and have stood all kinds of weather without any apparent evil effects. As pigs for 

 bacon production, however, they have proven to be a complete failure." 



Experiments with swine, K. Robertson, S. A. Bedford, and A. Mackay (Can- 

 ada Expt. Farms Rpts. t904, pp. 848, .a;//, 392, 398, 449, /,'>0) .—T\\q relative merits of 

 feeding in pasture and in pens were studied with 2 lots of 10 pigs each, the rations 

 being essentially the same for both lots. In the 153 days of the test, the total gain 

 made by the pigs fed most of the time in pasture was 1,439 lbs. ami by those fed 

 in pens 1,287 lbs., the cost of a pound of gain in the two cases being 3.55 cts. and 

 3.94 cts. 



At the Manitoba Experimental Farm ground barley was compared with ground 

 mixed grain (wheat, oats, and barley 1:1:1). In the 70 days of the test, four pigs 

 fed bai ley made a total gain of 254 lbs. A similar lot fed the mixed grain gained 205 

 lbs., the profit in the two cases being $7.85 and $5.52, respectively. "The pen fed 

 on barley consumed 40 lbs. more grain during the fattening period than those fed on 

 mixed grain." 



Ten pigs pastured on an acre of nearly ripe peas gained 277 lbs. in 47 days. 



At the Indian Head Experimental Farm a test was made of rape pasturage supple- 

 mented by a small amount of meal. In three months seventeen pigs made an average 

 Bin of 2(1.5 lbs. per head. Only about two-thirds of the rape on the half acre on 

 which they were pastured was eaten. As shown by a comparative test, the yield of 

 rape was 32 tons to the acre. The growth was quite rank and the pigs did not eat 

 ■targe amounts at first, and they seemed always hungry until their meal ration was 

 increased. 



Some data are also given regarding the pigs kept at the several experimental farms. 



Experiments with swine, M. Cumming {Ann. Rpt <>nt<<n<> Agr. Col. and K< pt. 

 Warm, SO (1904), pp. 97-Wl) —In a comparison of large and small amounts oi blood 

 meal and tankage with skim milk as part of a ration, and with meal alone, made with 

 8 lots ot 4 pigs each it was found that the greatest gain, 597 lbs., was made by a lot 

 led tankage, meal, and skim milk, 1:15:13, and the smallest gain, 4(31 lbs., by a lot 

 ted blood meal and meal, 1 : 14. 



The cost of a pound ol gain ranged from 3.48 cts. on a ration of tankage and meal 

 1 : 15 to 4.23 cts. on blood meal and meal 1:9. The test began rune 27 and closed 

 Nov. 23. All the lots received uniform treatment and were given some green feed 

 and toots in addition to the other feeds mentioned. According to the author, the 

 pigs fed on meal alone made very satisfactory gains but nut as targe as those made
