Chick-Growth Stimulation Produced by Surfactants

Surface Active Agents and the Time of Their Effect on Chick Growth with Special Reference to Vitamin B12 and Aureomycin Interrelationships

“…It did, however, improve growth over that of the basal chicks during the late stages of growth, confirming Ely's (1951) original report that certain surface active agents will stimulate the growth of chicks on a vitamin B 12 deficient diet. It is interesting to note that aureomycin and Ethomid C/15, when fed alone, resulted in chicks whose final average weights were approximately the same.…”

Comparative Growth Response of Chicks to Detergents, Germicides and Penicillin ,

“…The experiments in which Ely (1951) obtained growth responses to detergents were conducted with a basal diet apparently deficient in vitamin B12. Equal growth responses resulted from the addition to this basal diet of vitamin B12, detergent, or aureomycin.…”

“…Ely (1951) found that a lauryl ethylene oxide condensate and other synthetic detergents, such as are commonly used in household preparations, stimulate early growth of chicks when fed at 0.1% in the diet. In the data presented here, the growth responses of chicks to several detergents and germicides, at various levels in the diet, and to penicillin are compared.…”

Fat Studies in Poultry

“…Reports by Ely (1951) and Snyder et al (1953) indicate that surface active agents may stimulate growth rate of chicks in some instances. The surface tension of the intestinal contents may possibly be a factor in the rate and amount of absorption of fats.…”
