摘要: Abstract ALTHOUGH extensive research has been conducted in poultry genetics and nutrition, only limited information is available on genetic-nutritional interactions. Usually data the selection procedures nutritional regime employed developing stocks have too incomplete to fully determine Also when diverse were utilized experiments, analyses made a within-stock basis which precluded determination of any stock-ration interaction. The few reports that appeared literature interactions are somewhat contradictory. Nordskog Johnson (1953) reported highly significant ration-breed group interaction for 8-week body weight, Abplanalp (1960) stated strain-feed existed pullets but not cockerels. On other hand, Kondra Hodgson (1961) found no evidence strain-ration feed utilization or protein energy utilization. Slinger et al. (1955) who fed rations containing two levels stabilized …
