ANIMAL PRODUCTION. 469 



Two lots of 38 ewes each, witli their lambs, were feci for ;>"> days, begiuuiug 

 December 24. The ewes received the same ration as those in the second experi- 

 ment. ITie lambs of lot 1 received corn and alfalfa hay; those of lot 2, corn, 

 oats, bran, and oil meal 5:2:2:1, and alfalfa hay. The hay was fed ad libitum 

 and both lots received approximately the same amount of grain. Th'e ewes of 

 lot 1 lost G3 lbs. in weight; those of lot 2 gained 51 lbs. The lambs made an 

 average daily gain i)er head of 0.322. and 0.315 lb., respectively, costing 8.9 

 an<l S.5 cts. per pound of gain. The lambs of lot 1 were heavier and in higher 

 condition than those of lot 2. 



Hothouse lambs, born the last of November and first of December 1911-12, 

 were fed an average of 102.25 days and weighed when slaughtered 56.8 lbs. 

 each, having made an avei-age daily gain per head of 0.465 lb., and dressing 

 50.33 per cent. The cost of feed required per pound of live weight was 5.6 cts. ; 

 the .selling price. 35 cts. per pound, and the net profit per lamb, including pelts, 

 wool, and gains made by the ewe mothers, was $6.84. In the 1912-13 trial 

 the net cost of feed required per pound of live weight was 5.2 cts. and the 

 profit i>er lamb, $4.08. 



Hothouse lambs, born in July and August and maintained on clover pas- 

 ture and a small amount of grain until November 25, and then fed in the 

 ham, were produced at a smaller cost for feed than were lambs born in 

 the fall and raised in the barn during the winter, the cost of feed required per 

 pound of live weight being 4 cts. and the net profit per lamb, $5.35. 



[Hog production], B. Aune (U. 8. Dept. Agr., Bur. Plant Indus., Work Belle 

 Fourche E.rpt. Farm. 1913, pp. 7-9). — From experiments conducted at the Belle 

 Fourche Experiment Farm, S. Dak., it is estimated that the net value of gains 

 per acre of alfalfa made in 74 days by 153-lb. hogs, fed a supplementary feed of 

 2 lbs. per day per 100 lbs. live weight, of a grain mixture of ground wheat, oats, 

 and barley, was $11. The average yield of alfalfa hay was estimated at 3.5 

 tons per acre and its market value at $5 per ton. Pigs weighing 39 lbs. pas- 

 tured on third crop alfalfa for 20 days made a net gain of $10.12 per acre, 

 which was equivalent to about $9 a ton for the alfalfa consumed. On Sep- 

 tember 15 these young hogs were allowed to hog down a plat of .'M bu. per acre 

 corn. They remained in the corn 11 days, making a gain of 5(i0 lbs. per acre, 

 which was estimated to be worth $39.20, or $1.13 per bushel for the corn con- 

 sumed.

 S-36, figs. Jf3). — ^This circular gives general instructions on the judging and 

 scoring of horses and the detection of unsoundness.

 No. 3. pp. 203-266, figs. 2//). — An account of the development and use of the 

 various native breeds of horses in North Africa, and of the influence of the 

 introduction of the Barb, Arabian, and Syrian breeds upon the native stock. 



Report from the poultry division, V. Fobtieb and F. T. Shutt (Canada 

 E.vpt. Farms Rpts. 1913, pp. 671-682, pi. 1). — In experiments comparing the 

 effect of open and cotton -front poultry houses on egg production, it was found 

 that there was in general a higher egg yield from the cotton-front house during 

 the winter and early spring months. The minimum temperature in the cotton- 

 front house was 6° F.. and in the open front — 10°. 



Two pens of J 4 White Leghorn hens each were used to determine the effect 

 of a reiluction of ration on forcetl molting. The effect of the restricted ration 

 was to stop entirely the egg yield 15 days after the beginning of the experiment, 

 but the recovery from the molt was more rapid than in the instance of the lot 

 full fed and consequently the greater number of eggs was secured in the early 

 fall or the months of limited supply. Toward the end of the starvation period,
