By feeding a hen repeated daily doses of sodium dihydrogen phosphate of equal P32 activity, eggs with high and nearly uniform P32 content were obtained for use in hatching experiments. Eleven eggs were incubated. The embryos and chicks that died duri

Autor: J. R. Jowsey, H. I. MacGregor, F. D. Cook

Publikováno v: Canadian Journal of Animal Science. 39:21-25

Turkey poults were used to study the response to penicillin when administered in the feed, injected intramuscularly and injected intraperitoneally. A comparable growth response was obtained using all three routes of administration.Contents of the sma

Growth Response of Turkey Poults to Two Organic Arsenicals

Autor: H. I. Macgregor, J. R. Jowsey, R. M. Blakely

Publikováno v: Poultry Science. 40:909-911

GROWTH response to organic arsenicals in poultry rations was first reported by Morehouse and Mayfield (1946). Anderson, Cunningham and Slinger (1952) tested a group of these arsenicals and obtained a variable response. Initial experiments at this lab
