fed as supplements to shelled corn, clover hay, and corn silage. The lamhs fed 

 ground soy beans (lot 8) gained an average of 35.1 lbs. each at a cost of 9.76 

 cts. per pound, were valued at 14.15 cts. per pound, and returned a profit of $3.09 

 per head. Comparison was made with lot 7, reported under series I. 



V. Influence of shearing on fattening lambs. — In this experiment, lot 2, which 

 was shorn in the beginning of the test and yielded 57 lbs. of wool, was com- 

 pared with lot 7, as previously noted. The shorn lambs consumed slightly 

 more feed and gained an average of 33.8 lbs. per head at a cost of 10.72 cts. 

 per pound, w^ere valued at 11.75 cts. per pound, and made a profit of 96 cts. 

 per head. 



VI. Open shed v. ham as shelter for fattening lambs. — In this experiment 

 the lambs were all shorn. Those in the barn (lot 9) ate the same quantity of 

 grain and silage but less hay than those in the open shed (lot 2). The barn- 

 fed lambs gained an average of 33.1 lbs. each at a cost of 10.(58 cts. per pound, 

 were valued at 11.25 cts. per pound, and returned a profit of 51 cts. per head. 

 This experiment, together with five similar experiments, showed higher profits 

 from feeding lambs in open sheds than in the barn. 



Sheep, E. S. Aechibald et ax. {Canada Expt. Farms Rpts. 1916, pp. 532-559, 

 pis. 4)- — Two experiments were carried out with lambs at the Central Experi- 

 mental Farm, Ottawa, to compare the protein in various meals, to discover the 

 comparative value of two new protein meals recently introduced into Canada, 

 and to find the best nutritive ratio for fattening lambs. The 50 lambs in each 

 experiment were devided into five lots of 10 lambs each, and besides protein feeds 

 were given equal amounts of hay and silage. The grain was fed at the rate of 

 8 oz. per head in the beginning, increasing 2 oz. weekly until it reached 20 oz. 

 in the seventh week, at which rate it remained until the end of the experiment. 

 In the first experiment " short-keep " lambs were fed for the Christmas market 

 from November 17 to December 15, a period of 28 days ; in the second, " long- 

 keep " lambs were fed from November 17 to February 9, a period of 84 days. 



Average results from both experiments are shown in the following table : 



Average results of lamb-feeding experiments. 



During the winter of 1915-16, two lamb-feeding experiments lasting 110 

 days each were carried out at Charlottetown, P. E. I., beginning December 1, to 

 compare clover hay with mixed-grain hay (oats and barley cut in the milk 

 stage), and to compare a heavy grain ration with a light grain ration. Each 

 experiment included two lots of 10 lambs each. In the first experiment, in 

 addition to the roughage under test, both lots were fed turnips and a heavy 

 grain ration of barley, oats, and bran. Lot 1 received the clover hay as rough- 

 age; lot 2 received the mixed-grain hay up to February 20, when the supply 

 became exhausted and clover hay was substituted. Up to February 20, lot 1
