 also noted with these lots, the values being 7.2S and 4.o7 cts. 



With the yearling steers the greatest gain,. 2 lbs. per head per day. was noted 

 on the fnJl fattening ration, the e.xperimental period covering I'.KJ days, and the 

 smallest gain. 1.47 lbs. per head per day, with a l<»t fed the limited growing ration 

 for 1G9 days. With calves the daily gain on a limited growing ration was I..'', 

 lbs. per head in a test covering 201 days, and on a full fattening ration 1..54 lbs., 

 the cost of a pound of gain in the 2 cases being :\.'tH and S.4 ots., respectively. 



Cattle, R. Robertson, S. A. Bedford, and A. Mackay (Canada Expt. Farms 

 Rpts. mo,'), pp. 2S7. 288-297, SJ/l-SJfS, 39Jt-396).— The herds kept at the Mari- 

 time Provinces, Manitoba, and ludian Head exjierimental farms are described 

 find feeding tests rejiorted. 



At the Maritime Provinces farm, 8 steers fed loose in stalls gained 2,!mm» lbs. 

 in 10.J days as compared with 2,010 lbs. gained by a like number tied in stalls. 

 Considering all the steers the average dail.v gain was l.ij.j lbs. per head and 

 the cost of a pound of gain 9.33 cts. 



The influence of age on the cost of beef production was tested with 3-year-oIds, 

 2-year-olds, and yearlings, S animals constituting a lot in eacli case. The .3- 

 year-olds gained at the rate of 1.(34 lbs. per head per day, the cost of a pound 

 of gain being 8.76 cts. Similar values witli the 2-year-olds were 1.7() 11 )s. and 

 S.44 cts., and with the yearlings 1.7.'i lbs. and 7.00 cts. 



Continuing earlier work (E. S. R., 17. p. 171 ), full fattening and limited grow- 

 ing rations were compared. Summarizing the data it was found that steers 

 fed a full fattening ration for an average of 637 days made an average daily 

 .t,ain of 1.40 lbs. per head, the cost of a pound of gain being .5,78 cts. Animals 

 fed a limited growing ration for 1.108 days ou an average gained 1.08 lbs. per 

 head per day at a cost of 6.1 cts. 



At the Manitoba e.xperimental farm in a test covering 112 days, the average 

 daily gain made by a lot of 6 yearlings was 1 lb. 11 oz. per head per day and 

 by G 2-year-olds 1 lb. 7 oz. under similar conditions of feeding, the calculated 

 profit in the 2 cases being $2.22 and $2.51. The results were practically the 

 same as tliose obtained in an earlier test (E. S. R., 17, p. 172). "There is very 

 little profit in fattening steers when tlie difference between the buying price 

 in the fall and the selling price in the spi-ing is not more than $1 per 100 lbs." 



At the Indian Head experimental farm the average gain of 4 2-year-old 

 steers was 240 lbs. per head in a test covering 16 weeks and the calculated profit 

 per steer $.5.07. Similar values for a lot of 4 3-year-old steers fed a similar 

 ration were 210 lbs. and $4.17. 



Swine feeding, .J. H. Grisdale {Canada E.rpt. Farms Rpts. l<,)U'i, i>p. 70- 

 78). — Alfalfa, clover, and root pasture supplementing meal rations were com- 

 j)ared with roots and meal fed in pens and with meal fed in pens witliout sup- 

 I-lementary feed, using 5 lots of 5 pigs each. 



In the 35 days of the test the gain ranged from 1.31 lbs. per head per day on 

 root pasture to 1.77 li)S. witli the lot fed roots inside. The gain was most 

 cheaply made with the last-mentioned lot. costing 3.09 cts. per pound, and was 

 most costly, 4,23 cts. per pound, with the lot fed meal without supplement;iry 

 feed in pens. 



When pigs were jiastured on an acre of ri])(^ jieas " the returns in pork were 

 not satisfactory, but the effect of the exercise and tlie peas together was won- 

 derfully beneficial so far as form of i)igs was concerned and so far as fitting 

 them for finishing off for the packer when brought into the pens."
