568 EXPEEIMENT STATION KECORD. 



{1915), No. 1012, pp. 75-84, fiO- !)• — In this address the author discusses various 

 phases of the work of the hiboratory and describes some of the apparatus used. 

 The results of experiments, most of which have been noted from other 

 sources, are briefly summarized. 



ANIMAL PRODUCTION. 



Foodstuffs for animals and their valuation, F. A. Stockdale {Mauritius: 

 Dept. Agr., 1915, pp. 5). — ^Analyses are given of cane tops, manioc, sweet pota- 

 toes, wheat bran, rice bran, coconut meal, cotton-seed meal, and molasses. 



Some facts about concentrated feeds, W. H. Strowd {Wi^conMn Sta. Bui. 

 253 {1915), pp. 60, fig. 1). — Analyses are given of oil meal, cotton-seed meal, 

 gluten feed, distillers' dried grains, hominy feed, bran, wheat, middlings, shorts, 

 flour middlings, red dog flour, germ middlings, rye middlings, rye bran, barley 

 shorts, buckwheat bran, dried brewers' grains, dried brewers' yeast, malt 

 sprouts, alfalfa meal, tankage, blood meal, meat scrap, bone meal, tankage, 

 molasses feed, corn, corn-soy bean silage, alfalfa hay, dried potato peelings, 

 wet vinegar refuse, and various mixed and proprietary feeds. 



Vine prunings as fodder, F. de Castella {Jour. Dept. Agr. Victoria, 13 

 (1915), No. 5, pp. 310-314). — Successful experiments in feeding vine prunings to 

 cattle, sheep, and horses are reported. 



Silage feeding, C. I. Bbay {Oldahoma Sta. Circ. 36 {1914), PP- 2-S).— This 

 circular gives general information on the feeding of silage to live stock. 



The comparative values of cotton-seed, cotton-seed meal, and com, as 

 shown by chemical analyses, C. K. Francis {Oklahoma Sta. Circ. 31 {1914), 

 pp. 4). — Data as to the composition and digestible nutrients of raw cotton-seed 

 and cotton-seed meal are given. Suggestive rations for beef cattle and dairy 

 cows ai"e included. 



Coconut cake and palm-nut kernel cake {Jour. Bd. Agr. [London], 21 

 {1915), No. 11, pp. 1025-1032). — Data are summarized as to the average compo- 

 sition of coconut cake and palm-nut cake and digestibility coefficients, and a 

 general resume of experiments in feeding these products is included. 



It is said that palm-nut kernel and coconut cakes or meals are valuable feed- 

 ing stufl's, particularly for milch cows. They are also useful for replacing oats 

 for horses, but are probably of less value for fattening steers, sheep, and pigs. 



The feeding value of refuse brewers' yeast: Hungarian experiments, J. 

 SCHANDL {KozteleJc [Budapest], 24 {1914), No. 16, pp. 2658, 2659; abs. in Inter- 

 nat. Inst. Agr. [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 6 {1915), No. 2, 

 pp. 216, 211). — The composition of brewers' yeast is given as moisture 87.G7 per 

 cent ; protein, 6.69 ; fat, 0.14 ; nitrogen-free extract, 4.49 : and ash, 1.01. 



It is said that the product can not be used for feeding purposes as it comes 

 from the brewery, owing to the danger of abnormal or excessive fermentation 

 in the stomach of the animal, and to its bitter taste and strong smell. After 

 subjecting it to a simple cooking process it was readily accepted by sheep and 

 pigs, but cows and horses refused to touch it until after 24 hours, when the dis- 

 agreeable taste and smell had disappeared. 



In an experiment in which two rams were fed 1.5 lbs. of chopped clover and 

 0.5 lb. of yeast the digestibility coefficients of the yeast were dry matter, 89 

 and 54 per cent ; protein, 97 and 86 per cent ; and nitrogen-free extract 82 and 

 86 per cent, respectively. 



In experiments with five cows fed in three periods of 30 days each, as follows : 

 First and third periods 4.4 lbs. of sunflower cake, second period 2.2 lbs. of sun- 

 flower cake and 11 lbs. of yeast, it was found that the yeast exerted no speciflc 

 influence on the yield of milk.
