Iieets were fed in different proportions and the energy balance estimated. Afco 

 a comparison was nrade of the energy value of dried turnip tops and of ensiled 

 lurnip tops in whieli had been introduced a lactic acid culture, in which a 

 greater amount of coail)ustible gases developed in the body of the animals fed 

 the ensiled i)roduct than the dried, the i)rotein retention was greater with the 

 <lried product than with the ensiled, but the fat outake was greater with the 

 ensiled product. The practical results of these experiments are summarized 

 as follows: 



The carbohydrates of molasses have a higher nutritive value for horses and 

 swine than for ruminants, being highly usable by them. The degree of fer- 

 mentation of the molasses is such tliat one should not feed much protein-rich 

 feed, but such as is fed should be supplemented with a roughage feed. The 

 organic acids of the feeds have a heat value. Reduction of the stomach 

 fernientatiou with the feeding of acid or ensiled materials is doubtful. 



New inquiries concerning' the feeding of sugar-containing feed stuffs, 

 ZuNTz (/Jsclir. Vcr. Deut. Zuvkerindus., No. 70S (1914), II, pp. 643-668). — In 

 this article the author reviews the work presented in the above experiments, 

 showing wherein sugar-containing feeds, such as molasses and sugar beets, 

 are au insufficient feed in themselves, giving rise to fermentation within the 

 body and necessitating supplementing with straw, hay. and other roughage. 



Calf- and pig-feeding experiments with, whole milk and corrected skim 

 milk, O. WiXLMANN (Landir. Jahrb., J,6 (IDUi), Xo. .',. pp. Jf'J0-(j26). — In these 

 experiments one calf and eight pigs ranging in age from four to twelve weeks 

 w^ere fed at different times on whole milk, skim milk to which diafarin (a 

 malt extract preparation) had been added, skim milk to which a meal starch 

 had been added, and homogenized milk. The coefficients of digestibility for 

 the various rations were as follows: 



Coefficients of digeHtihility with niUk.s and nirioit.'< supplements. 



The daily increase in weight ranged between 2.5 and 3.1 kg. per 100 kg. live 

 weight, the daily gain increasing with advancing age. There was required per 

 kilogram of gain fi'om 1.2 to 1.8 kg. of milk dry matter. 1.1 to 1.7 kg. digestible 

 organic matter, 52 to 70 gm. digestible ash, 259 to 439 gm. digestible protein. 

 1.1 to 1.9 kg. starch value, and 5,000 to 9,000 available calories. 



Steer feeding experiments {Jahresber. Kaiser Wilhehns Inst. Landw. Brom- 

 bcn/, 1913, pp. 18, 19). — Two lots of 17 head of steers each were fetl daily 

 during 5* months, 1.7 kg. digestible protein and 12 kg. starch value per 1.000 

 kg. live weight. Both lots were fed hay. potatoes, beets, barley meal, rape 

 seed, rye bran, and cotton-seed meal, but lot 1 received the potatoes, beets, and 

 rye bran in the morning ration and the remainder at night, while lot 2 received 

 the entire feed both morning and night. 



Lot 1 made an average daily gain of 0.091 kg. per head, and lot 2, 0.735 kg. 

 On continuing this experiment for another 4 weeks, except that the steers re-
