A.NIMAL PRODUCTION. 



.Many of the wheal by-producte examined were found to contain an undue am-. nut 

 of screenings and quite often corn, the amount of the latter being from a tra 

 some 30 per cent, [nferior wheal was also sometimes found. The molass 

 usually met their guarantees, but the authors do not consider them to be as econom- 

 ical as high-grade protein by-products. The data regarding the poultry feeds exam- 

 ined were included in a bulletin previously noted E. S. R., 16, p. 903).

 ',55; abs. in Centbl. Agr. Chem. , 84 (1905) , No. 8, pp. 190-192). Analyses of dried 

 grape pomace are reported and its feeding value discussed. 



Phosphate of lime in the feeding of farm animals, .1. P. Wagneb (Jour. Soc. 

 Cent. Agr. Belg., 52 I 1905), No. 8-10, pp. 268-281).— From a summary of available 

 data tin- conclusion is reached thai the importance of phosphate of lime for the 



formation of bone and for the digestion and assimilation of f I is generally r< 



nized. Under ordinary circumstances the rations fed supply a sufficiency of this 

 material. It, fur any reason, this is nol the case and mineral salts must be resorted 

 to precipitated calcium phosphate of known purity should be used. 



Present methods of beef production, III, II. W. Mumford and L. D. Hall 

 i Illinois Sta. Circ. 91, pp. 4)- — Information regarding pigs following cattle in the feed 

 lot is summarized, the data as in the case o"f previous publications I E. S. R., L6, pp. 

 805, 1112) being based upon replies received from a large number of Illinois cattle 

 feeders in answer to a circular letter of inquiry. 



( >f the 509 cattle feeders who furnished data on the subject, 90 per cent kept pigs 

 with cattle when on feed, and 70.7 percent of those who stated a preference as to 

 breed favored Poland-Chinas. Whatever the breed, pigs 6 months old or those 

 weighing on an average 125 lbs. were generally preferred, and 56 per cent of the feed- 

 ers allowed ] pig to each steer. Eighty-three per cent of those who keep pigs with 

 their eattle fed corn in addition to the feed which they could gather. Nine per 

 centofthe correspondents who replied stated that they secured less than I lb. of 

 gain per head per day when no additional corn was fed to the pigs, 42.5 percent 

 secured a gain of 1 lb. per head per day, and 49 per cent more than 1 lb. With refer- 

 ence to the proportion of the corn fed to the cattle which should l>e charged to the 

 pigs following them, three-fourths of the correspondents stated that one-fifth to "iie- 

 thhd should be charged to the pigs. 



Oil meal when fed to steer- is often said to have a beneficial effect on the pigs fol- 

 lowing them. Thirty-seven per cent of those who furnished data on this point noted 

 an advantage, while the remaining 63 per cent did not. Forty per cent of the feed- 

 ers had found that cotton-seed meal fed to cattle is injurious to the pigs following 

 them, while 60 per cent had noted no injurous effect-. A small number of the cor- 

 respondents mention other supplementary feeds (usually condimental stock fe< 

 which, in their opinion, have given as good results as oil meal. 



"One of the most successful feeders states in his repoii that he has used success. 

 fully a self-feeding box in supplying mineral substances to the hogs. Wood ashes 



are mixed by the wagonload with salt, copperas, and sulphur, and placed in a small 



Belf-feeder similar in construction to those used for catl le." 



Only s per cent of the correspondents furnish permanent house- for their pigs, 

 while practically all the remainder furnish no shelter except that afforded by the 

 sheds and barns provided for the cattle.
