“…In this study, the results showed that turmeric, MOS and Biostrong increased the TAO, GPx and SOD activities that promoted the ability of rabbits treated to resist the stress of the biological and environmental. These results were in agreement with the results of (Zeweil, et al, 2016;Abdelnour, et al, 2022). Harrison, et al (2003), Zeweil, et al (2016 and Badr (2019) concluded that Turmeric, MOS and Biostrong have pharmacological antioxidant activities, especially the mixture of their, therefore, it can reduce oxidative damage to lipids and proteins as well as DNA to provide a defense against cellular damage.…”

O ne of the main reasons for the low productivity of farm animals, especially rabbits, is climatic changes because they have thick fur and lack of sweat glands, which makes them suffer from excessive heat loss, which affects their productivity. The growth and reproduction rates of adult female rabbits are affected as a result of exposure to severe heat stress (30-31 ºC) (Marai et al., 2001). The consequences of exposure to high temperatures on rabbits were shown in terms of low pregnancy rate, fetal growth, birth size, birth weight and milk production, and mortali-ty before and after weaning increase (Morsy and Abd El-Lateif, 2017).Rabbits are characterized by critical physiological and hormonal changes during their reproductive cycle, making them more susceptible to these climatic influences (Mady, et al., 2018). The solution was to find effective nutritional supplement alternatives to improve the harmful effects of heat stress (El-Kholy et al., 2018;Hashem et al., 2021). Turmeric (Curcuma longa) is phytogenic additives, rich in research ArticleAbstract | Ninety mature does New-Zealand White rabbits age 6 months and weighting 3.2 kg were assigned randomly into six treatment groups. The treatments were fed basal diet as control (G1), basal diet plus 0.3 % turmeric (G2), 0.05 % MOS® (G3), 0.015 % Biostrong® 510 (G4), 0.05 % MOS +0.3 % turmeric (G5) and 0.05% MOS +0.015 % Biostrong (G6), respectively. Rabbits fed with turmeric, MOS and Biostrong recorded a significant (P≤0.05) increase in doe weight at mating, prepartum, partum and weaning period, and the rate of feed intake increased in the treated groups, especially the G5 through gestation period and the G3 in lactation stage. The milk yield also increased in the rabbits in treated groups, especially the G5, and it appeared clearly in the third parity. Birth size at birth and at weaning, birth weight and milk production were increased (P ≤ 0.05) in all treated groups in compared to the control group. Results have also shown that turmeric, MOS and Biostrong led to a significant increase in total protein, globulin, total antioxidant capacity (TAO), glutathione peroxidase (GPx) and superoxide dismutase (SOD), with significant improve in A/G ratio and decrease malondialdehyde (MDA) in the treated groups in compared to the control group. In conclusion, turmeric, MOS and Biostrong supplements had a beneficial effect as natural antioxidant additives, especially the mixture among them, by protecting against oxidative stress factors caused by pregnancy and lactation in female rabbits under heat stress.

“…El-Ratel et al ( 107 ) demonstrated that extra virgin olive oil supplementation (300 mg·kg −1 ) increases plasma testosterone concentration and GSH activity, sperm output, sperm cell counts, intact acrosome, sperm normality, while reduces sperm cells with abnormal tail and plasma MDA contents in male rabbits under heat stress. Abdelnour et al ( 108 ) found that inclusion of 100–150 mg·kg −1 thyme essential oil in the diet improves the haemato-biochemicals constitutes, immunologic status, antioxidant capacity, reduces the lipid peroxidation, thus enhancing the fertility traits (e.g., litter size, viability rate at birth, viability rate at weaning) and milk production. The positive effects of essential oils mainly attributed to the antioxidant activity ( 156 ).…”

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.

“…ALC may promote sperm mitochondrial functionality recovery after HS exposure by increasing antioxidant capacity, decreasing oxidative stress and increasing autophagy and apoptosis (Qiao et al, 2021). In our previous work on frozen–thawed rabbit sperm, (Abdelnour, El‐Ratel, et al, 2022, Abdelnour, Hassan, et al, 2022) suggested that supplementation of ALC (4 mM) to the freezing extender enhanced the ultrastructure integrity, MMP activity, antioxidant capabilities as well as decreased lipid and protein peroxidation.…”

The reproductive consequences of global warming representing heat stress (HS) have been widely received more attention in the last decades. HS induced significant influence on the male reproductive cell, especially sperm functionally. Reduction in the sperm function induced by HS leads to failure of fertility potential. The main effects of HS on sperm are reducing sperm motility, increased abnormalities and changes in the fluidity of the membrane as well as cell morphology. Moreover, the destruction of mitochondrial function could be the result of adverse influences of HS. The protein contents and enzymes of mitochondria were lowered after the exposure of sperm to HS. Some natural antioxidants were used for improving sperm mitochondrial function under HS conditions. In this review, it was highlighted the potential influences of HS on sperm function through reduction in ATP Synthesis yield, mitochondrial activity, mitochondrial protein contents and mitochondrial enzymes, which involves the interference of mitochondrial remodelling in sperm of animals.
