576 EXPERIMENT STATION EECORD, 



lbs., the 2-year-olds 327 lbs., and the yearlings 318 lbs. There were 782 lbs. 

 of pork produced following the 3-year-olds, 738 lbs. following the 2-year-olds, 

 and 389 lbs. following the yearlings. Placing a value of 1 ct. a pound on 

 concentrates and $8 a ton on hay, the average profit per head for the 3-year- 

 olds was $16.4G, for the *2-year-olds $12.85, and for the yearlings $13.20. This 

 includes the pork produced but not the manure. 



In shipping to market, a distance of 586 miles, the home-bred lots were fed 

 sheaf oats and the range-bred lots prairie hay. The average losses per head 

 for the lots fed sheaf oats were 3-year-olds 61 lbs., 2-year-olds 56 lbs., and 

 yearlings 37 lbs. ; for the lots fed prairie hay the average losses wex*e 3-year- 

 olds 53 lbs., 2-year-olds 49 lbs., and yearlings 39 lbs. 



[Distillery slop for beef cattle] (Breeder's Gaz., 59 {1911), No. 2fi, p. 

 lJil2). — An account of the methods of feeding distillery slop as practiced in 

 Kentucky, where about 50 per cent of the beef produced is made from distillery 

 waste, although it is stated that the industry is diminishing because distillers 

 obtain a better price for their slop when dried and shipped to Europe. 



Cost of raising lambs, G. E. Day (Ann. Rpt. Ontario Agr. Col. and Expt. 

 Farm, 36 {1910), pp. 135-137). — In an experiment with 10 lambs dropped from 

 March 1 to March 5 the average weight at 2 months was 55.2 lbs. and the cost 

 of gain 6.S5 cts. per pound. This includes all food consumed by the ewes dur- 

 ing the whole year, and service fees, less value of wool, but does not include 

 risk, interest, and labor. The rations of ewes and lambs from lambing con- 

 sisted of oats, bran, oil cake, roots, and alfalfa. Five of the lambs in the 

 above experiment were kept on pasture with no supplementary feed until 

 October 15, when they were put upon feed consisting of oats, oil cake, bran, 

 hay, and roots for 30 days, at which time the 5 lambs weighed 664 lbs. and had 

 cost 4.58 cts. per pound. The average daily gain for the 5 .lambs before going 

 to pasture was 0.71 lb., on pasture 0.37 lb., and in pen on full feed 0.47 lb. 



Experiments with, swine, G. E. Day {Ann. Rpt. Ontario Agr. Col. and Expt. 

 Farm, 36 {1910), pp. 138-141)- — The average cost per pig for raising 72 pigs 

 to 11 weeks of age was $2.46. This includes service fees, maintenance of dry 

 sows, and value of food consumed by sows and litters, but does not include 

 risk, interest, labor, and manure. 



Several experiments were conducted with 40 of these pigs to compare alfalfa, 

 skim milk, and pasture, using corn meal as a check. In 90-day tests the meal 

 alone produced an average daily gain per head of 1.07 lbs. ; meal and alfalfa 

 pasture, 1 lb. ; meal and green alfalfa in pens, 1.13 lbs. ; meal and skim milk 

 in pens, 1.34 lbs. ; meal, skim milk, and green alfalfa in pens, 1.36 lbs. In 

 these tests 1 lb. of meal was equal to 4.3 lbs. green alfalfa or 6.79 lbs. skim 

 milk. Valuing the i)igs at $5 each, the skim milk at 20 cts. per 100 lbs., and 

 the green alfalfa at $3 per ton, the price received per ton for meal with the 

 hogs selling at 5 cts. per pound was $20.45, and at 8 cts. $53. 



On the use of barley, barley feeds, and maize for fattening swine, H. Bock 

 and D. Engberding {Fiihling's Landw. Ztg., 59 {1910), No. 2^, pp. 841-858).— 

 Pigs about 7 months of age fed for a period of 49 days made an average daily 

 gain per head of 0.711 kg. (1.56 lbs.) when maize and palm-nut cake were used 

 as a supplement to potato flakes and skim millv, and 0.605 kg. when barley and 

 an additional quantity of potato flakes were given as a supplement. There was 

 but little difference in the percentage of dressed weight in the lots, or in the 

 analytical constants of the fat, except that the melting point of the fat in the 

 maize-fed lot was 2 per cent higher than that of the barley lot. 



The development of the body of cattle from birth to the end of the grow- 

 ing- period, W. Wagner {Arb. Deut. Gescll. Zilchtungsk., 1910, No. 8, pp. 162, 

 tables 15, pis. H). — This contains data on the growth of cattle, determined
