Seven trials, using commercial broiler chicks, were conducted to determine the effects of varying dietary energy and protein levels in combination with feeding time on growth, feed conversion, body composition, and energy and protein consumption. In

There is little experimental evidence published on the effect of the commonly used feeding systems on growth and market quality of turkeys reared on range and in confinement. Funk (1943) found that growing turkeys will over-eat on a high protein conc

THE widespread use of artificial insemination in the turkey industry has resulted in a problem of when to inseminate the breeder flock for optimum fertility and the efficient use of labor. Malmstrom (1943) observed that the presence of a hard-shelled

ROBERTSON et al. (1948) reported that an increase in volume of a diet from a value of 0.64 to one of 1.10 liters per pound of diet through the use of wheat by-products and oats lowered chick weight about 20 percent at 4 weeks of age. Their data indic
