ANTMAL PRODUCTION. 1067 



Feeding experiments with, peptone feed, Gerlacii {Illus. Lanclw. Ztf/., 27 

 {1907), Xo. SO, pp. 6'J7, 698). — So-called peptone feed is uuide by drying the 

 stomach contents of slaughtered animals and mixing the material with molasses. 

 A fewling test was made with lambs which led the anthor to concUide that 

 the digestible nntrients of peptone feed liave a higher feeding value than those 

 in other concentrated feeds bnt that it has no other special recommendation.

 No. 7, pp. I'll-l.'iJf). — The relative amount of calcium and phosphoric acid in 

 a number i»f feeding stuffs, tlie importance of these ash constituents in animal 

 feeding, the value of bone meal and other conunercial feeds supplying sucli 

 mineral constituents, and related questions are discussed.

 data regarding horses and other farm animals, poultry raising, rabbits, and 

 fish.

Experiments in beef production in Alabama, J. F. Duggar and W. F. Ward 

 U. S. Dcpt. Agr., Bur. Aiiiin. Indus. Bui. 103, pp. 28, pis. 11). — Three tests were 

 made to compare cotton-seed hulls with farm-grown forage (sorghum hay 

 and shredded corn stover) and to determine tlie relative values of cotton seed, 

 cotton-seed meal, and corn. In each series of tests 10 lots of .5 steers each were 

 used. The value of shelter was also taken into account and the merits of 

 grades and scrubs. 



Considering the results for 3 years, the average daily gains with cotton-seed 

 meal as the .sole concentrated feed were as follows: 1..5."> lbs. when fed with cot- 

 ton-seed hulls, 1..39 lbs. when fed with cut sorghum fodder, and 1.19 lbs. per 

 head when fed with shredded corn stover. 



" With mixed cowpea and sorghum hay as the roughage, and with one-third 

 of the concentrate consisting of cotton-seed meal, the daily gain per steer from 

 feeding cotton seed was 1.68 lbs., and from feeding an equal weight of corn-aud- 

 cob meal 1.71 lbs. 



"To produce 1 lb. increase in live weight required practically equal amounts 

 of cotton seed and of corn-and-cob meal. This shows that under the conditions 

 of these experiments a pound of cotton seed was equally as valuable as a pound 

 of corn-and-cob meal. Cotton .seed is cheaper per pound, and hence is the more 

 economical feed. 



" Cotton-seed meal proved more effective and economical than corn-and-cob 

 meal when each was fed as an appetizer in connection with cotton seed. 



" When, in a ration of cotton-seed meal, one-third of tlie weight of the cotton- 

 seed meal was substituted for an equal weight of corn-and-cob meal, the daily 

 gains were slightly increased. The amount of concentrate per iiound of gain 

 was greater with the mixed ration, making this slightly less profitable than the 

 ration containing cotton-seed meal as the sole concentrate. 



"The effect of shelter varied with the character of the winter. In 2 tests 

 shelter increased the daily gains and decreased the amount of feed required per 

 pound of gain. . . . 



";rhe scrub steers in 2 experiments made practically the same daily gains at 

 practically the same cost as the grades. At the beginning of the other experi- 

 ment the scrubs were thinner, and they gained more rapidly and economically.
