ANIMAL PRODUCTION. 371 



From the results of a feeding experiment, previously noted (E. S. R., 29, p. 

 366), the opinions and experiences of several farmers as to the feeding value 

 of flax products, and other data, it is concludetl tliat the farmer is justified in 

 feeding these products in moderation, with due precautions against poisoning. 

 Additional feeding experiments, hov^ever, are regarded as desirable. 



Grape foliage in animal feeding, J. Girard (Jour. Soc. Cent. Agr, Jlaute- 

 Garonne, 23 (1913), Xo. 2.'/5, pp. 171-176).— Gnipe foliage is fed to cattle either 

 dried or ensiled, and is found to be both palatable and nutritious. The silage la 

 preferred. As a forage, the leaves retain their green color and possess a pleas- 

 ant odor. The usual daily allowance is from 10 to 15 kg. (22 to 33 lbs.) per 

 head together with a grain ration. 



Investigations on the change in the nutritive value of feeds from ensiling 

 and on the consequent loss of nutritive value, IV, A. Zaitsciiek (Landw. 

 Vers. Stat., 7S {1012), 'So. 5-6, pp. 40 1-Jf 08). —This is a continuation of work 

 previously noted (E. S. R., 25, p. 479; 26, p. 360), experiments in feeding swine 

 being conducted to determine the comparative feeding value of fresh and ensiled 

 beets. 



It is noted that the nutritive value and digestibility are lowered as the result 

 of ensiling. This loss w^as especially noticed with beets stored for the entire 

 winter and removed in the spring. Beets removed from storage in February 

 suffered less loss of sugar and other nutrients. The net available energy value 

 of fresh beets is reported as 38.04 calories per kilogram, and for ensiled beets 

 33.73 calories. 



Silo and silage catechism, R. H. Mason (South Carolina Sta. Circ. 12, pp. 

 3-16, figs. 6). — ^A general circular treating of the different types of silos, silo 

 construction, silage crops, filling the silo, and feeding silage. 



Fodder and method of making" same, V. Christensen ( U. S. Patent 1,073,591, 

 Sept. 23, 1913; abs. in Jour. Soc. Chem. Indus., 32 (1913), No. 20, p. 987).— 

 " The concentrated saccharin juice of the agave is mixed with nitrogenous and 

 cellulose substances, and the mixture dried and ground to form a * conservable 

 complete fodder.' " 



Comparative value of brewery residue mixed feeds for ruminants, W. 

 VoLTz, W. Dietrich, and A. Deutschland (Wchnschr. Brau., 30 (1913), No. 45, 

 pp. 575-578). — In sheep-feeding trials mixed feeds of chopped straw and brewery 

 residue, and turf meal, charcoal, and brewery residue were fed. The relative 

 digestibility, starch value, and feeding value of these feeds were determined 

 and their economy demonstrated. The starch value for the chopped straw 

 mixture was estimated at 55.65 kg. per 100 kg. of dry matter and that of the 

 turf meal mixture at 23. S5 kg. 



Peanut bran in Germany, R. P. Skinnee (Daily Cons, and Trade Rpts. [U.S.^, 

 16 (1913), No. 270, pp. 890, 891).— An account is given of the use of peanut shells 

 and the red hulls which envelop peanut kernels for stock feeding. The shells 

 are high in cellulose content and low in nutritive ralue, but the material is mixed 

 with other feeds of higher value and is frequently used in the com.position of 

 molasses feeds to give them body. Peanut bran made from the hulls is said to 

 contain varying amounts of fat and is considered a serviceable secondary stock 

 feed. 



Commercial feeding stuffs, R. F. Kolb and B. B. Ross (Feed Stuff Bui. Ala. 

 Dept. Agr., 1911-12, No. 54, pp. 64). — This bulletin includes a discussion of the 

 nutritive value of feeding stuffs, the calculation of rations, and the dangers re- 

 sulting from the feeding of spoiled feeds. Analyses are reported of middlings, 

 shorts, bran, screenings, molasses feed, dried beet pulp, mixed feeds, and pro- 

 32052°— No. 4—14 6
