Some facts and theories about silage, T. A. Kiesselbach {Ann. Rpt. Nebr. 

 Com Improvers' Assoc, 6 (1915), pp. 108-131, figs. 3). — A resume of experi- 

 ment station work on tlie value and use of silage. A bibliography of literature 

 on silos and silage is included. 



Silage in relation to farm management, G. F. Waeeen (Ann. Rpt. Nebr. 

 Corn Improvers' Assoe., 6 (1915), pp. 94-108, fig. 1). — A resume of experiment 

 station material showing the place of silage in the economics of the farm and 

 its cost, food vahie, and use. 



Cassava pulp from the manufacture of fecula, A. de Vill£:le (Rev. Agr. 

 R6union, 2. ser., S (1915), No. 10, pp. 359-369). — Analyses are given of cassava 

 pulp, together with comments on its feeding value for various classes of live 

 stock. 



Concentrated feeding stuffs and registrations for 1915, C. S. Cathcaet et 

 AL. (New Jersey Stas. Bui. 283 (1915), pp. 3-90). — Analyses are given of alfalfa 

 meal, bread meal, brewers' dried grains, buckwheat middlings, buckwheat offal, 

 ground corncob, corn-and-cob meal, corn bran, corn meal, corn (sifted cracked), 

 gluten feed, coconut meal, cotton-seed meal, distillers' dried grains, dried beet 

 pulp, feeding flour, hominy meal and feed, linseed meal, malt sprouts, meat meal 

 and beef scrap, malt gi-ains, oat hulls, peanut meal, bone meal, rye bran, rye 

 middlings, ground screenings, shredded wheat waste, wheat bran, wheat mid- 

 dlings, and various mixed and proprietary feeds. 



Nutrition investigations (Kansas Sta. Rpt. 1914, PP- 19, 20). — The results 

 of four feeding trials, including 90 pigs, indicate that young pigs fed corn meal 

 without other feed or corn meal supplemented with various ash ingredients 

 are much below normal development at the close of the six months, whereas 

 young pigs fed corn meal supplemented with proteins low in ash develop 

 normally during six months' feeding. These results indicate that a protein 

 deficiency, quantitative or qualitative or both, is the chief limiting factor. The 

 influence of the ash in combination with the protein has not been determined. 



Results of two feeding trials, not completed, with 12 steers indicate that 

 scanty feeding does not materially hinder growth in height, but greatly retards 

 the development of the middle and width of the body ; that one year of main- 

 tenance feeding, if followed by liberal feeding, does not materially stunt the 

 animal, but does not allow maximum development of the width of the body, 

 and that two years of maintenance feeding, followed by liberal feeding, results 

 in permanent stunting, which is indicated by lack of normal height, contracted 

 middles, and narrow bodies. 



[Experiments with swine and steers], E. S. Good (Kentucky Sta. Rpt. 1914, 

 pt. 1, pp. 38-42). — lu a series of experiments to determine the value of dis- 

 tillers' dried grains as a feed, alone and in combination with other feeds, for 

 hogs on pasture, four lots of from 10 to 15 pigs each were fed for 73 days. Lot 

 1 was allowed the run of a pasture of rape and oats, and fed all the distillers' 

 dried grains it would eat without waste. Lot 2 was allowed the same kind of 

 pasture and given from 2.5 to 3 per cent of its weight in corn meal per day; 

 lot 3 was given a similar pasture and allowed from 2.5 to 3 per cent of its 

 weight per day of a mixture of corn meal and distillers' dried grains 5 : 1. For 

 comparative purposes, the fourth lot was confined in a dry lot and given a full 

 feed of corn meal and distillers' dried gi-ains 5 : 1. These lots made average 

 daily gains per head of 0.456, 0.931, 1.027, and 0.883 lbs., requiring 3.68, 3.44, 3, 

 and 4.44 lbs. of grain per pound of gain, and costing, not considering the cost 

 of the pasture, 4.97, 4.95, 4.27, 6.32 cts. per pound of gain for the respective lots. 

 The results of this experiment indicate that distillers' dried grains are not well 

 relished by the hog, and that it is not so satisfactory a feed for hogs on pasture 

 as is corn alone, or a mixture of corn meal and distillers' dried gi-ains 5 : 1.
