ANIMAL PRODUCTION. 



667 



cotton-soetl meal sold in Massachusetts, due to the growing tendency to incor- 

 porate more hulls, is reported. 



Cacao shells are described as the hard, outside coating or bran of the cacao 

 bean. Their use in this country as a feeding stuff has been quite limited, but 

 in Europe they are used as a partial feed for horses and cattle and as an adul- 

 terant for oil cakes. liargo quantities are also used by the Swiss as a feed for 

 draft oxen. It is held that they act as a stimulant to the nerves and muscles 

 aud enable the animals to do a greater amount of work. An analysis is re- 

 ported as follows: Water 4.5, protein 1.3.9, fat 4.91, nitrogen-free extract 55.61, 

 hber 12.05, aud ash 8.43 per cent. 



In feeding trials with wheat screenings the fiber did not appear to be at all 

 digestible, indicating somewhat of a depressing effect upon the fiber digestibility 

 of the hay, and the fiber contained in the weed see<ls of the screenings was of 

 decidedly inferior character. In chemical composition and digestibility the 

 screenings did not ai)pcMr to vary greatly from wlieat bran. 



In experiments with sheep the following coefficients of digestibility were 

 obtained for the several products: 



Digestion coefficients icith sheep for various feeds. 



Analyses of these various feeds are included. 



Concentrated commercial feeding stuffs, J. D. Turner and H. D. Spears 

 {Kentuckif 8ta. Bui. 185 (Wl-i). pp. J67W/71).— Analyses are reported of alfalfa 

 meal, blood meal, tankage, dried-beet pulp, corn bran, corn chop, cracked corn, 

 corn-feed meal, corn-germ meal, hominy feed, cotton-seed meal and feed, oil 

 meal, rolled oats, rye feed, wheat bran, shorts, middlings, shipstuff, dried 

 brewers' grains, dried distillers' grains, molasses feed, and various mixed aud 

 proprietary feeds. 



Concentrated feeding stuffs and registrations for 1914, C. S. Catiicart 

 {yeio Jersey Stas. Bui. 211 (lOUf), pp. 3-85). — Analyses are reported of the 

 following feeding stuffs: Alfalfa meal, brewer's dried grains, buckwheat bran, 

 buckwheat middlings, buckwheat offal, corn-feed meal, corn-and-col) meal, corn- 

 germ meal, cotton-seed meal, cotton-seed meal and hulls, distillers' dried grains — 

 corn and rye — dried-beet pulp, feeding flour, gluten meal, gluten feed, hominy 

 feed, hominy meal, linseed meal, malt sprouts, meat meal and beef scrap, 

 mustard bran, oat hulls, rye bran, rye middlings, shredded wheat, wheat bran, 

 and wheat middlings, and various mixed and proprietary feeds. A discussion 

 of the findings under the new law and other data are included. 



Experiments on the nitrogen economy value of sodium acetate for rumi- 

 nants, E. Pesciieck {Biochem. Ztsclir., 62 {191J,), Ao. 3-J,, pp. 1SG-21S).— 

 Experiments of Weiske and Flcchsig in 18.S9 are discussed in which sheep 

 were fed hay, peanut cake, potato starch, and sugar as a basal feed with 

 ap[)roximately 80 gm. per day of .sodium acetate, the addition of sodium acetate 

 reducing the nitrogen output in the urine over that in animals fed on the basal 

 ration alone. Later experiments by Gabriel in which salt was added to the
