Abstract
Abstract PAYNE et al. (1957) have reported a correlation of +0.39 between body weight of turkey hens and the weight of their egg. Funk (1950), however, did not observe a consistent difference in numbers of eggs laid by hens differing in body weight. Fertility and hatchability were found to be correlated negatively with body weight by Kondra and Shoffner (1950). Fertility was related to posture in males according to Robblee et al. (1957). Rooney (1957), by using artificial insemination at relatively long intervals, was able to estimate the incidence of natural mating occurring in Broad Breasted Bronze hens. Selection at different ages for increased body weight at maturity (Abplanalp et al., 1963) provided several lines of turkeys on which the effect of selection for body weight on reproduction was tested. MATERIALS AND METHODS Parental stock was selected from Broad Breasted Bronze turkeys using weight as the main criterion. The selection of…
