Physical traits and reproductive success in male primary broiler breeders
Genetic selection for high yield in primary broiler breeder males may result in skeletal modifications that impede sperm transfer upon mating. In addition, fluctuating asymmetry (FA) in bilateral traits has been shown to reliably indicate male reproductive potential in some avian species. The goal of this study was to determine if physical variation due to genetic selection and FA could explain...
متن کاملon Reproductive Performance of New Zealand White Rabbit Bucks

Groups 2, 3 and 4 were injected subcutaneously (under nick skin) with 200, 400 and 800 μg GA /kg B.W./week for 6 weeks treated period, while group 1 was serve...
متن کاملEffect of Dietary Lecithin Supplementation on Improvement Semen Quality, Reproductive Performance Plasma Biochemical Traits and Antioxidant Changes in Rabbit Bucks
Lipids are the main structural/functional components of the sperm, and their composition may undergo a series of modifications in relation to either physiologic events and/or diet. The effect of lecithin supplementation on reproductive and reproductive performance were studied in rabbits bucks. Twenty eight adult V line rabbits (at age between 7-8 months) were divided into four equal groups. Th...
متن کاملBrain and psychological mediators of imitation: sociocultural versus physical traits
The acquisition of cultural beliefs and practices is fundamental to human societies. The psychological and neural mechanisms underlying cultural acquisition, however, are not well understood. Here we used brain imaging to investigate how others’ physical and sociocultural attributes may influence imitative learning, a critical component of cultural acquisition. While undergoing fMRI, 17 Europea...
متن کاملPredicting the physical activity level of adolescent girls based on perceived physical literacy: the mediating role of cognitive abilities
