968 EXPERIMENT STATION RECORD. 



jiidliortion of the fat in tho milk. The caivass of u corn-fpd lamb contained a 

 much larger proportion of fat than the carcass of a lamb fed upon cotton- 

 seed meal. 



Specific gravity methods for determining freshness of eggs were found un- 

 reliable. Small active breeds of poultry do better with a wide ration than 

 large breeds. liens fed linseed meal molted rapidly and earlier in the season 

 than those receiving a large amount of tallow. Oyster shells were found to be 

 utilized largely in the construction of the eggshell. Cockerels were found the 

 most profitable when sold at about (I lbs. weight, and capons when fed until 

 about !) lbs. in weight. Eleven ])er cent more eggs were obtained from hens 

 when kept in i)ens without cockerels. From a number of experiments it was 

 found that with growing stock ground grain gave on the whole better results 

 than whole grain. Kations containing animal food were superior to those of 

 vegetable origin for growing chicks, laying hens, and ducklings. 



Of a number of coarse feeds fed to swine none were eaten without waste except 

 mangels. With fresh forage crops better gains were made when salt was added 

 to the ration. Corn silage, red clover, and sorghum proved to be good feeds 

 when given in small amounts. 



The computation of rations for farm animals by the use of energy values, 

 H. r. AuMsiiv I i'. S. Dciit. Afir., Fanners" Bid. .J'/O'. />p. 32). — The feed require- 

 ments for maintenance, growth, fattening, milk production, and work are 

 treated in this bulletin from the standard of energy values instead of the 

 lialanced-ration method commonly used in popular works on feeding. The 

 method for computing rations is presented in such form that it is intelligible to 

 the practical farmer, though based on fundamental principles as revealed by 

 scientific investigations. 



Feeds and feeding', W. A. Henry, trans, by F. ]M. Draenert (Forragcm c 

 Xiitrkao. ^Cto Paulo, 1907, pj). XI\'+700). — A Portuguese translation of this 

 work (E. S. R., 10, p. 82). 



Concentrated commercial feeding stuffs, W. J. Jones, O. C. IIaworth, and 

 J. B. Abbott (Iiuliuna Sta. Bill. 131, pp. 305-^65). — This bulletin contains the 

 text of the Indiana feeding stuff law of 1907 and a discussion thereof, together 

 with the results of analyses of 1,361 samples of feeding -stuffs, including wheat 

 bran and middlings, red-dog flour, mixed feeds, rye products, buckwheat bran 

 and middlings, corn bran, hominy meal and chops, gluten feed, linseed meal, 

 flax screenings, cotton-seed meal, dried brewers' grains, malt sprouts, pro- 

 lirietary and molasses feeds, poultry and scratch feeds, animal meals, and con- 

 dimental stock feeds. There is also a list of brands and guaranties registered 

 by manufacturers in compliance with the law. 



" Since very few manufacturers had ever had their products analyzed it was 

 to be expected that many would make their guaranties too high. In tlie 

 ma.i'ority of cases the guaranty was based on the average analysis of the 

 products as given in Circular No. 7 published by this station [E. S. II., 19. p. 

 67], and while a large number of samples failed to meet the guaranty, and 

 there is much room for improvement in the character of the feeding stuffs 

 offered for sale, a decided increase in the number of sami)les meeting the 

 guaranty is noted in those now being secured and in the case of many others 

 the guaranty has been lowered to meet the inspection analysis." 



The value of fodder plants at different stages of maturity and the proper 

 time for harvesting the same, J. Konig and A. Furstenberg (Zcntbl. Agr. 

 Chciii., 37 {litOS), \o. 11, pp. ?-'/5-7.'/.'M . — Analyses were made of grass and of 

 clover hays cut before, after, and at the time of l)lossoming. Tlie results 

 agreed with practical experience that hay should be cut when in blossom.
