Experiment with steers, R. Robertson, S. A. Bedford, and A. Mackay ( ( 'anada 

 Expt. Farms Rpts. 1903, pp. 284, 287-294, 383-386, 392-394) .—The relative merits 

 of feeding steers loose and tied in stalls were studied at the Maritime Provinces Farm 

 with 2 lots of 8 dehorned steers, each fed similar rations of hay, roots, silage, and 

 mixed meal for 150 days. The total gain made by the loose steers was 2,435 lbs. 

 and by the tied steers 2,250 lbs. 



In a comparison of full fattening and limited growing rations it was found that a 

 lot of 5 calves on a full fattening ration made an average daily gain of 2.32 lbs. at a 

 cost of 6 cts. per pound for 150 days. Similar values for 5 calves fed the limited 

 growing ration for a year were 0.86 lb. and 5.30 cts. In a second test the steers fed 

 the full fattening ration made an average daily gain of 1.44 lbs. at a cost of 5.21 cts. 

 per pound, and with those on a limited growing ration the average daily gain was 

 0.95 lb. per steer and the cost of a pound of gain 3.64 cts. The above tests were 

 made in continuation of those previously reported (E. S. R., 15, p. 172). 



At the Manitoba Experimental Farm brome-grass hay was compared with corn 

 fodder, using 2 lots of 5 steers each. The lots were all fed turnips, chopped mixed 

 grains, and bran in addition to the coarse fodders mentioned, and were handled 

 similarly. In the 32 weeks of the test the steers fed brome-grass hay made an aver- 

 age daily gain of ] lb. 10 oz. and those fed corn fodder 1 lb. 12 oz. According to 

 the authors' calculations the profits were, respectively, 64 and 71 cts. per steer in 

 the 2 lots. 



"There is very little profit in feeding steers when the difference between the buy- 

 ing and selling price is only about 75 cts. per steer. Cattle require more pounds of 

 fodder corn per day than they do of brome-grass hay. The comparative value of 

 these 2 fodder crops is about *4 per ton for fodder corn and $5 for brome hay." 



The gains made by steers turned out 2 hours each day, as compared with those 

 kept continually in the stable, were studied at the Indian Head Farm with 2 lots of 

 5 animals each fed under uniform conditions. In the case of the steers turned out 

 a part of each day the total gain in the ISO days of the test was 1,520 His. and the 

 calculated profit per steer $2.14 as compared with 1,615 lbs. and £2.74 for the steers 

 confined all the time.
