1917J ANIMAL PEODUCTION. 67 



54 cts., $1.16, 80 cts.. $1.20, $1.33, and 31 cts., for the respective lots. Lot 4, fefl 

 the pulverized screenings with blackseed removed, after the first two weeks 

 apparently consumed the meal with relish. Lot 5, on pulverized blackseed, re- 

 fused the ration almost entirely for five weeks, and at the conclusion of the 

 experiment were consuming about half the quantity fed. Lot 6, on equal por- 

 tions of pulverized blackseed and molasses meal, consumed the ration cleanly 

 from the start. No toxic effect was noticed from the use of the by-product in 

 any of its grades. These lambs when finished for market, all lambs receiving 

 the same meal mixture, composed of oats, bran, and oil cakes, 2:2:1, made 

 average dally gains per head for 55 days of 0.28, 0.19, 0.33, 0.33, 0.43, and 

 0.36 lbs., at a cost per pound of gain of 9.4, 13.5, 7.7, 8.6, 6, and 7.1 cts. Lots 

 5, 6, and 3, receiving blackseed in various proportions, were all losing weight 

 at the end of the regular experiment, having apparently reached their limit of 

 production on a roughage diet supplemented by inferior meal. The results of 

 this finishing period indicate that the blackseed-fed lambs were held back during 

 the experiment, as evidenced by their very rapid comparative gains during the 

 finishing period. 



Five lots of 11 Iambs each were fed 135 days as follows: Lot 1, clover hay; 

 lot 2, mixed clover and timothy hay and corn stover ; lot 3, timothy hay and 

 mangels ; lot 4, clover hay and roots ; lot 5, clover hay and oil cake. They made 

 average daily gains per head of 0.085, 0.071, 0.084, 0.132, and 0.149 lb., at a cost 

 per pound of gain of 18, 20, 18, 12, and 11.9 cts., for the respective lots. 



The average results of three years' tests of clover hay, mixed hay and corn 

 stover, and timothy hay and roots as roughage for fattening lambs, show the 

 average daily gains per head for 3 lots of 42 lambs each to have been 0.107, 

 0.058, and 0.063 lbs., for 103 days, at a cost per pound of gain of 15.5, 24.7, 

 and 20.4 cts., respectively. 



Four lots of lambs were fed 108 days as follows : Lot 1, timothy hay and 

 meal ; lot 2, timothy hay, roots, and meal ; lot 3, a mixture of timothy hay and 

 broadleaf hay and meal ; lot 4, a mixture of timothy and broadleaf hay and 

 roots and meal. They made average daily gains per head of 0.215, 0.29, 0.209, 

 and 0.274 lbs., at a cost per pound of gain of 11.1, 10.32, 12.39, and 11.68 cts., 

 for the respective lots. 



Three lots of breeding ewes were wintered as follows : Lot 1 in an open shed, 

 fed alfalfa ; lot 2 in a sheep barn, fed alfalfa ; lot 3 in a sheep barn, fed mixed 

 hay. They made gains per head of 5.6, 5.1, and lb., while the lambs made a 

 gain per head of 5.8, 0, and — 6 lbs., for the respective lots. 



Three groups of lambs of two lots each, bought at Lethbridge, Alta., one lot 

 fed barley straw, prairie hay, and a grain mixture of oats and barley, 1 : 1, and 

 the other lot fed barley straw, prairie hay, and wheat screenings, one group being 

 fed in a closed shed, one group in an open shed, and the third group in the open, 

 made average daily gains per head for 112 days of 0.13 and 0.13 lb. in the two 

 lots of the first group, 0.2 and 0.9 lb. in the two lots of the second group, and 

 0.19 and 0.19 lb. in the two lots of the third group, at a cost per pound of gain 

 of 11 and 11 cts., 7 and 8 cts., and 8 and 8 cts. for the respective groups. 



In a corresponding test with lambs bought at Indian Head, Sask., the average 

 daily gains per heau were 0.12 and 0.12 lb. for the lots fed in the closed shed, 

 0.2 and 0.2 lb. for those fed in the open shed, and 0.15 and 0.16 lb. for those fed 

 in the open, at costs of 12 and 12 cts., 7 and 7 cts., and 10 and 9 cts. for 

 the respective groups. 



A test in fattening a single pure-bred Shropshire wether indicated that the 

 feeding of home-bred lambs may be profitable in Saskatchewan, while there is 

 little or no profit in buying lambs.
