“…However, semen pH did not significantly change due to different supplemental antioxidants. The present findings are in agreement with many studies (Sharaf et al, 2019;El-Kholy et al, 2020;El-Ratel et al, 2021). They reported an alteration in the sperm motility of rabbits' semen associated with high ambient temperature.…”

he present study was conducted to investigate the effects of feeding corn silk, orange peel, and pomegranate peel extracts on semen quality, blood biochemical constituents, antioxidants capacity of male New Zealand White rabbits under heat stress conditions. In an experiment that lasted 8 weeks, thirty male rabbits aged twenty-four weeks with an average body weight of 2.85±0.1kg were randomly distributed into five equal groups (6 rabbits/ group). Each rabbit was kept in an individual cage. The first group (control) was fed a basal diet. The second group (positive control) was fed the basal diet supplemented with vit E. at a level of 250 ppm. The third, fourth, and fifth groups were fed the basal diet supplemented with corn silk, orange peel, and pomegranate peel extracts at a level of 150 ppm, respectively. Experimental diets were offered ad-libitum and clean drinking water was freely available. The overall average of ambient temperatures and relative humidity were 31.1°C and 62.5%, respectively. Overall temperature-humidity index (THI) through the experimental period was 29.14 indicating severe heat stress conditions. According to the results of the HPLC screening for the different extracts: ferulic acid, cinnamic acid and coumaric acid were the most abundant polyphenols in orange peel extract, while gallic acid was the most abundant polyphenol in pomegranate peel extract. Semen quality parameters improved in rabbits of orange peel and corn silk groups, opposite to rabbits fed pomegranate peel extract. The activity of seminal catalase and glutathione peroxidase increased in rabbits fed orange peel and corn silk extracts. Blood total proteins, albumin, globulins and creatinine were not affected by different antioxidants supplements. Serum total antioxidants capacity, catalase and superoxide dismutase were significantly increased in all experimental groups compared with the control. In conclusion, the current results showed that using orange peel or corn silk extracts as feed supplements at a level of 150ppm could improve semen quality as well as antioxidants capacity of male rabbits reared under heat stress conditions.

“…Vitamin E can alleviate the immunosuppression caused by the release of adrenal cortex hormone at high temperatures and promote the synthesis of immunoglobulin to improve the body's disease resistance and reduce mortality ( 125 ), vitamin E can also reduce the serum cortisol levels, thereby reducing rabbit's adverse reactions to heat stress ( 126 ). Studies showed that adding vitamin E to the water increased the normal sperm, volume, count, motility, live sperm and T3, T4 hormonal levels, then decreased the rectal, skin, ear temperature and respiration rate, thus improving the fecundity of male rabbits ( 81 ). However, vitamin E supplementation had no significant effect on reducing the body temperature of rabbits under heat stress ( 24 ).…”

Heat stress has become a widespread concern in the world, which is one of the major environmental stressors and causes substantial economic loss in the rabbit industry. Heat stress leads to multiple damages to the health of rabbits, such as organ damage, oxidative stress, disordered endocrine regulation, suppressed immune function and reproductive disorders, ultimately, induces the decreased production performance and increased mortality. Nutritional approaches, including feeding strategies, adjusting feed formula, and supplementing vitamins, minerals, electrolytes, Chinese herbal medicines, and functional active substances to the feed, were reported to mitigate the detrimental effects of heat stress in rabbits. Therefore, elucidating the damage of heat stress to rabbits; proper management and nutritional approaches should be considered to solve the heat stress issue in rabbits. This review highlights the scientific evidence regarding the effects of heat stress on rabbit's immune function, endocrine, blood biochemical changes, antioxidant capacity and production performance, and the potential mitigation strategies of nutritional intervention to alleviate heat stress in rabbits; which could contribute to develop nutritional strategies in relieving heat stress of rabbits.

“…Furthermore, adding vitamin E to drinking water decreased the serum cortisol concentration, ameliorating HS' unfavorable influences on female rabbits' productivity [98]. Regarding rabbit males, Sharaf et al [99] pointed out that the administration of vitamin E in drinking water enhanced the semen quality characteristics (live sperm, normal sperm, volume, count, and motility) and decreased dead sperm, rectal temperature, skin temperature, ear temperature, and respiration rate under HS conditions, and these findings might be attributed to the antioxidative properties of vitamin E.…”

Ramifications of Heat Stress on Rabbit Production and Role of Nutraceuticals in Alleviating Its Negative Impacts: An Updated Review

Heat stress has become a widespread concern worldwide, which is a major environmental stress that causes substantial economic loss in the rabbit industry. Compared to other agricultural animals, rabbits are more sensitive to heat stress as they have fewer sweat glands and a thicker coat of fur, increasing the heat dissipation complexity. Thus, heat stress hurts rabbits’ productivity, meat quality, reproductive performance, antioxidative properties, immune responsiveness, intestinal histomorphology, and microbiome. Nutraceuticals include vitamins, minerals, antioxidants, organic acids, fatty acids, probiotics, prebiotics, synbiotics, enzymes, and medicinal plants due to the possible impacts on maintaining common biological situations, strengthening immune response, and preventing illness, which ultimately led to an increase in productivity. Nutraceuticals have recently attracted a lot of attention to alleviate the adverse impacts of heat stress in rabbit farms. The objective of the current review is to provide acquaintance with the recent findings about the impact of heat stress on rabbit productivity and the advantages of dietary supplementation of nutraceuticals in mitigating it.
