The Effect of Different Antibiotics on Growth of Turkey Poults

Abstract

A MARKED growth promoting effect of a fermentation supplement, now known to contain aureomycin, for turkey poults was reported by McGinnis et al. (1949). This growth response was obtained under conditions where materials containing vitamin B12 failed to give a stimulus. Stokstad et al. (1949) also reported that a fermentation supplement produced by Streptomyces aureofaciens promoted better chick growth than that obtained with vitamin B12. More recently Stokstad and Jukes (1950) showed that a highly purified preparation of aureomycin promoted growth of chicks and turkey poults comparable to that obtained with a dried aureomycin fermentation mash. Luecke et al. (1950) found that streptomycin was effective in promoting growth of pigs. A similar effect of aureomycin on growth of pigs was observed by Jukes et al. (1950). Morehouse (1949) reported that 3-nitro-4-hydroxybenzene arsonic acid stimulated growth of turkeys fed a practical type of diet. A series of experiments were conducted at . . .
