1919] ANIMAL PRODUCTION. 869 



the lambs on i-ape had regained all they lost at the beginning and were forging 

 ahead. . . . During the tifth week of the test continuous rains fell ; the pas- 

 tures freshened up greatly and the difference in favor of rape was not so 

 marked as it would have been under normal summer conditions." 



There were no cases of bloat. 



Influence of strictly vegetable diets on growth and reproduction of swine, 

 B. B. Hart and E. V. McCollum (Amcr. 8oc. Aniiu. Prod. Proc. 1915, pp. 49-53, 

 figs. 4)- — This paper gives the details of an investigation previously noted 

 (E. S. R., 35, p. 563). IMicrophotographs are reproduced of sections of the 

 spinal cord of a normal and of a grain-fed pig. The spinal cord of the latter 

 showed a marked edematous condition with the motor cells noticeably con- 

 stricted. 



Alfalfa pasture for hogs, R. H., Williaais and W. S. Cunningham (Arizona 

 Sta. Rpt. 1917, pp. 466, 4^7). — Two lots of five Duroc- Jersey pigs were fed a 

 daily ration of from 2 to 3 lbs. of rolled barley and 6 lbs. of skim milk per 

 100 lbs. live weights, for 12 weeks. One lot had access to a small alfalfa 

 pasture and gained 433 lbs. during the period. The other received no forage 

 and gained 373 lbs. The former lot consumed 80.5 lbs. more barley and 108 

 lbs. more milk and showed much more finish. 



Another test with two pigs on alfalfa pasture without other feed is cited, 

 in which the respective gains were only 6 and 7 lbs. during 8 weeks, while litter 

 mates fed grain and pasture gained 40 lbs. each. 



[Dry lot finishing of hogs following peanut pasture], G. S. Templeton 

 (Alabama Col. Sta. Circ. 40 (1919), p. 26). — Seventy hogs were grazed for 8 

 weeks on peanut pasture. They were then divided into two lots, one of 40 

 head being continued on peanut pasture for another period of 6 weeks, and 

 a second of 30 head being fed in a dry lot on corn and tankage in a self-feeder. 

 At the close of the 6 weeks' period they were marketed. The lot fed 14 

 weeks on peanuts were classified by the packer's expert as oily, and sold for 

 15 cts. per pound. Those finished in the dry lot were classified as medium 

 soft and sold for 15.5 cts. 



Cottonseed meal as a feed for hogs, J. C. Burns (Amer. Sac. Anim. Prod. 

 Proc. 1915, pp. 15-20). — A 96-day feeding experiment during the winter of 

 1914-15 at the Texas Experiment Station is reported, in which cottonseed 

 meal was used as a supplement to milo maize chop in fattening 110-lb. hogs. 



It was found that untreated cottonseed meal in amounts sufficient to balance 

 the ration (1 part in 7) gave results equal to fermented cottonseed meal 

 (1 part in 7, and 1 part in 4) previously found satisfactory (E. S. R., 18, 

 p. 667), and to unfermented meal (1 part in 4) treated with ferrous sulphate 

 solution as recommended by the North Carolina Experiment Station (E. S. R., 

 31, p. .578). The average daily gains per head varied from 1.24 to 1.26 lbs. in 

 the different cottonseed meal lots, while in the check lot which received no 

 supplement it was only 0.65 lb. There were no fatalities, but the lot fed the 

 heavy ration of fermented cottonseed did not eat well toward the end. 



It is pointed out that cottonseed meal is ordinarily one of the cheapest 

 sources of protein at the command of the southern hog raiser, and its use 

 should not be abandoned because heavy or prolonged feeding is injurious. " It 

 would not be advisable to feed more than one-half pound of meal per 100 lbs. 

 of live weight per day to any class of hogs for a very long period, and if 

 continuous meal feeding is practiced it would be well not to feed over 0.35 

 lb., or 10 per cent of the whole ration when hogs are on full feed."
