Abstract

The study aimed to evaluate the reproductive traits in poultry breeder with different weight ranges of two semi-heavy lineages. The experimental method was completely randomized design in factorial arrangement (3×2) with two factors: reproductive methods (artificial insemination and natural mating) ...

Abstract

Having antioxidant and androgenic effects, Chrysin was orally administrated to roosters and reproductive performance including sperm quality and fatty acid composition, testis index, fertility and hatchability rates as well as blood testosterone concentration were assessed. Twenty eight 40-week-old ...
