The historical development of poultry husbandry in Germany, A. Beeck 

 (Jour. Amer. Assoc. Instr. and Invest. Poultry Eush., 1 (1915), No. 8, pp. 57-GO, 

 61, 62). — ^A resume of the development of the poultry industry in Germany. 



A poultry survey of the city of Ithaca, O. B. Kent {Jour. Amer. Assoc. 

 Instr. and Invest. Poultry Htisl)., 1 {1915), No. 6, pp. -^5-47). — Data are given 

 on the sources of supply and the consumption of eggs and poultry in Ithaca, N. Y. 



Animal food for poultry, H. W. Jackson {Jour. Amer. Assoc. Instr. and 

 Invest. Poultry Hush., 1 {1915), No. 7, pp. 53, 5-'i. — The author reviews avail- 

 able experimental work on feeding animal food to poultry, in which it appeared 

 that meat-fed chicks made quicker and cheaper gains than others, regardless of 

 size, and that chicks started on a ration deficient in animal food never regained 

 their lost ground. He also reports his own experiments, in which hens without 

 meat generally began laying before meat-fed hens and maintained their position 

 for weeks and even months on such rations. He concludes that although the 

 work done by most investigators has usually shown a decided superiority for the 

 meat-fed laying hens, there is sufficient evidence the other way to warrant fur- 

 ther investigation. In the fattening of fowls animal food has appeared to be 

 essential to the best results, except when milk has been used, but of the various 

 sources there seems to be little preference aside from convenience or economy. 



The substitutes for animal food in common use are milk, milk albumin, -or 

 dried milk, vegetable sources of protein, and bone ash or phosphate sources. 

 Milk albumin has not generally given good results. Milk, sour or otherwise, has 

 given conflicting results. Vegetable protein when used under favorable condi- 

 tions has often given as good results as when protein from animal sources has 

 been used. Results of feeding bone ash or some carrier of phosphorus indicate 

 that some of the advantage that has been claimed for animal protein may pos- 

 sibly be due to the mineral matter contained in the meat scrap or cut bone. 



The value of mineral elements in poultry feeding, M. A. Jull {Jour. Amer. 

 Assoc. Instr. and Invest. Poultry Husl)., 1 {1914), ^^o. 2, pp. 1-3). — Experiments 

 are cited which show that mineral elements are essential for the functioning 

 of the vital processes as well as for the development of bone and eggs. 



A resume of chick feeding, Clara Nixon {Jour. Amer. Assoc. Instr. and 

 Invest. Poultry Husb., 1 {1915), No. 6, pp. Jfl, 48). — This summarizes the princi- 

 pal results of chick feeding experiments at the various experiment stations. 



E-eport of second twelve months' poultry laying competition, 1913—14, at 

 Harper Adams Agricultural College, Newport, Salop, W. Brown {Field 

 Expts. Harper Adams Agr. Col., Salop and Staffordshire, Rpt. 1914, pp. 83, 

 figs. 6). — This reports a second egg-laying competition (E. S. R., 31, p. 472) in 

 which the various breeds of poultiy were compared. 



It was found that a steady, though small, amount of fish meal tends to pro- 

 duce a constant supply of eggs. The amount used was only 2.4 per cent of the total 

 feed given. It is believed to be a mistake to give a full meal in the afternoon, 

 since this tended to increase the number of soft-shelled eggs. The birds yielded 

 a larger number of eggs if they were fed gradually during the day and given 

 only a light feed at night. They consumed about 89.05 lbs. of feed per bird 

 during the 12-months period, the heavy breeds consuming 91.07 lbs. per bird 

 and the light breeds 86.55 lbs. 



Inbreeding. — Its effect on vigor and egg laying, J. Dryden {Jour. Amer. 

 Assoc. Instr. and Invest. Poultry Hush., 1 {1915), No. 3, p. 19). — The author 

 reports the results of his studies at the Oregon Experiment Station.
