IN STUDIES with poults, utilizing a washed Drackett protein-sucrose basal diet calculated to be adequate in known nutrients, a mixture of unidentified growth factor supplements was found to markedly improve growth and to be protective against a non-r

IT HAS been demonstrated during the past few years that turkeys require dietary zinc for growth and for bone and feather development. Studies with purified experimental diets have indicated that a level of approximately 60–65 ppm. zinc is required

IN A previous report from this laboratory, tests were described in which the early growth of poults was improved when 0.3% KCl was added to a washed soy protein-sucrose type experimental diet containing 0.37% potassium, all but an insignificant amoun

Markedly different results were obtained in a recent experiment when poult diets containing increasing levels of corn oil were fed with and without an antibiotic. On the premise that antibiotic effects are due to modification of intestinal microflora

In recent tests in our laboratory, Maryland Medium White poults fed to three or four weeks of age on a vitamin E and selenium-deficient Torula yeast diet (Table 1) consistently developed a high incidence of gizzard dystrophy, the definitive sign of v

PREVIOUS work in this laboratory indicated that a minimum of 0.6% potassium is required in purified poult diets to insure maximum early growth (Supplee and Combs, 1959). In contrast, Kratzer et al. (1958) failed to obtain a growth response from addit

The growth of chicks decreased, and specific abnormalities of hocks and feathers increased, when cadmium was added to a zinc-deficient diet. Supplementation of the diet with zinc prevented the adverse effect of cadmium on hock and feather development

Previous tests by Supplee and Combs (1960) with Maryland Medium White poults indicated that 0.6% potassium (hereafter designated as K) was required in a sucrose-soy protein diet for maximum early growth. When 50 to 75 p.p.m. oleandomycin phosphate wa

SummaryMaryland Medium White and Beltsville White poults reared under germ-free conditions showed excellent growth on a purified type washed Drackett protein starch basal diet. Supplementation of the diet with procaine penicillin (45 mg/kg) or with o
