Both genetics and environment play an important role in the growth, performance and overall welfare of poultry species. Current commercial production practices typically do not mimic the natural environmental conditions of ancestral poultry species, specifically lighting requirements. In nature, poultry species are subjected to natural day length and the slow rising and setting of the sun. This is compared to commercial conditions in which lights are sudden on/off, not mimicking the natural trajectory of the sun in terms of light intensity and exposure. The current study aimed to evaluate the impact of genetics and the effect of sunrise/sunset lighting on …

Heat stress hampers gut health by impeding its ability to absorb nutrients which leads to a lower feed efficiency and sicker birds. Therefore, there is a critical need to identify mechanism-based strategies to alleviate these effects. Polynesian poultry farmers have been supplementing broiler feed with Morinda Citrifolia (Noni), a medicinal plant high in anti-oxidants, to address this problem. The purpose of the present study was to evaluate the effect of Morinda Citrifolia (Noni)-supplementation on the expression of tight junction proteins. Male Broilers (Cobb 500, 3 wks, n=480) were subjected to 2 environmental conditions (TN, 24°C vs. HS, 35°C, 1 …
