“…This reaction results in the destruction of thousands of poly unsaturation of fatty acids molecules [27]. ROS damages the biological systems for example hydroxyl radical (•OH), superoxide anion radical (O 2 -), singlet oxygen (O 2 ) and hydrogen peroxide (H 2 O 2 ) are continuously produced in the process of normal aerobic cellular metabolism [26,27]. However, these oxidative molecules can damage healthy cells if they are not eliminated.…”

“…The DNA defects of the sperm cause birth defects. Several studies have explored that male birds supplemented with increased quantity of vitamin E had improved sperm quality and/or motility when compared with control group [21,27]. The results showed that the semen volume, sperm motility, and sperm capacity in fertilizing eggs were increased in vitamin E supplemented group as compared to control group.…”

Vitamin E plays a significant role in growth, tissue integrity, reproduction, nervous system and disease resistance. Fertility plays a vital role in human, animals and avian species. But, several factor such as climatic variation, diet, minerals, and vitamins can affect fertility. Vitamin E acts as an antioxidant and increases disease resistance against infectious agents in animals which, in response, increases fertility in animals and poultry birds. Vitamin E performs an excellent role in birds including egg production, egg fertility, hatchability, sperm motility, conception rate, and postnatal growth. Its main function is to inhibit the production of reactive oxygen species (ROS) in the cells and tissues. In addition, Vitamin E provides biological stability to spermatozoal plasma membranes in male birds and maintains the egg quality in female birds by preventing the generation of ROS. Numerous studies have described that vitamin E deficiency reduced fertility in humans and avian species. However, very less data is available on vitamin E supplementation and its deficiency on the fertility of poultry birds. Therefore, this paper aim was to explore the effects of the supplementation of vitamin E on the fertility of poultry birds in order to understand the beneficial role of vitamin E in the maintenance of sperm and egg qualities. This review may provide important scientific information to better understand the mechanism of vitamin E and its possible effects on fertility functions in the poultry species.

Heat stress (HS) affects the production performance in chickens and causes economic loss to the producers. Most of the studies have been conducted on and for the welfare of broilers. We still lack information on the physiological parameters being affected during chronic heat stress in layers. To fill this gap, the present study evaluated the effect of heat stress (induced in the chamber) during the prelaying period (21–23 weeks) on plasma levels of the hormones leptin and ghrelin and GH and expression of the respective receptors and heat stress markers. Three groups were considered, one at room temperature (CR) and the other two groups (SH and CH) subjected to heat stress at 39°C for four hours for three weeks (21–23 weeks of age). The SH group (SH) feed was supplemented with fermented yeast culture (FYC, 700 mg/kg), whereas the CH group was devoid of it. After that, all the groups were shifted to shed under natural ambient conditions till 31 weeks of age. Studies were restricted to production performance only. Feed offered without yeast culture (CH group) had a smaller concentration of plasma hormones ( P < 0.01 ) and increased expression fold of the hormone receptors ( P < 0.01 ). Further, the group also presented higher liver AMP kinase enzyme, plasma MDA (malondialdehyde), and cholesterol concentrations. These changes likely explained the decrease in feed intake and the CH group’s body weight and further reduced the production performance during the laying period. Supplementation with FYC to birds had an opposite effect on the above-mentioned parameters, reducing HS effects. In summary, supplementation with FYC (700 mg/kg) maintained physiological parameters as in the CR group under HS conditions and negated adverse effects on parameters both before and during laying periods.
