“…Recently, Farghly et al reared rabbits under various light conditions and found that rearing animals under LED conditions resulted in the highest glucose concentrations. 93 In addition, Niemierzycka et al showed that LED light with a color temperature of 4200 K achieves higher speeds with maintained accuracy on the Kraepelin test. 94 As the Kraepelin test induces PFC activity 95 and glucose is primarily present in the brain, it can be inferred that LED light plays a different role than incandescent light on the PFC.…”

“…This soon gets exhausted as temperature further increases. Continuous exposure of rabbits to extremes of heat leads to disruptions in homeostatic mechanisms, thereby causing damages to various organs (Farghly et al, 2021). The responses of rabbit when the body heat load exceeds the heat loss capability are termed heat stress.…”

One of the major problems facing rabbit production is heat stress in hot regions of the world, especially in Egypt through summer season. This is further aggravated by global warming being experienced as a result of climate change. Climate change is a variation or change in the climate (temperature, wind, precipitation patterns) in a specific location, region, or the entire planet. This change in weather patterns persists for a long period of time ranging from decades to millions of years.Heat stress adversely affect welfare and adaptation, feed consumption and utilization, immunity, health status, growth, reproduction, and milk production in rabbits. Rabbits have no or few sweat glands and thicker fur, increasing the heat dissipation complexity. Thermoregulation is extremely poor in rabbits because lack of sweat glands so, they are highly sensitive to high temperatures. This review summarizes available literatures in the last few decades (1990-2023).

“…Rabbits stretch their ears to dissipate heat through radiation and convection, similar in function to a radiator (Marai et al, 2007). These responses make the heart work hard and result in the body's loss of salt and water through perspiration and urination, affecting the rabbit's efficiency, and causing haemo-concentration (Farghly et al, 2021;Oladimeji et al, 2022). Exposing rabbits to severe heat stress activates physiological mechanisms to balance the excessive heat load, leading to an increase in the thermoregulatory parameters (Adelodun et al, 2015;Jimoh and Ewuola, 2016;Abd El-Monem et al, 2016).…”

“…A decrease in feed consumption is a common reaction to heat stress conditions (Ali and Abdel-Wareth, 2014;Okab et al, 2008). This reduction is the result of the peripheral thermal receptors stimulation, which transmit suppressive nerve impulses to the appetite center in the hypothalamus, causing a decrease in feed intake (Dalle Zotte and Paci, 2014;Terhes et al, 2018;Liang et al, 2022), thereby a decreased feed efficiency and live weight (Farghly et al, 2021;Oladimeji et al, 2022). Ali and Abdel-Wareth (2014) suggested that the lower body weight may be due to the increase in energy consumption by increasing the respiratory rate during heat stress.…”

Heat stress is a detrimental factor affecting the welfare of all livestock, especially rabbits, as they are sensitive to high temperatures. The current study investigated the effect of high ambient temperature on growth performance, slaughter traits, physiological indicators, and some hematological and biochemical parameters in Algerian local growing rabbits. A total of 48 local rabbits of both sexes (35 days old) were allotted into two groups (24 per group). The control group rabbits were exposed to an ambient temperature and humidity, averaging 21.8 ± 1.3°C and 51.7 ± 3.6%, respectively. Rabbits in the heat stress group were subjected to a warm ambient temperature and humidity of 30.5 ± 1.82°C and 65.5 ± 7.2%, respectively. The growth performance was measured and calculated from 35 to 91 days of age. Physiological indicators (rectal, skin, and ear temperatures, respiratory, and heart rates) were examined at 88 days of age. The carcass traits, blood metabolites, and hematological parameters of rabbits were measured and calculated at slaughter (92 days of age). The obtained results indicated a decrease in body weight, daily gain, and daily feed intake of rabbits in heat stress rabbits, compared to the control group. However, feed conversion ratio was significantly higher in the heat stress group, compared to the control. Heat stress group rabbits showed significantly higher blood metabolite levels, except the glycemia, which was similar in both groups. No significant effect of heat stress was found on the carcass yield, anterior, posterior, and intermediate parts of the carcass. However, the yield of the other components of the carcass (liver, kidney, peritoneal and inter-scapular fat) was significantly lower in the heat stress group. In the heat stress group, rectal, skin, and ear temperatures as well as heart and respiratory rates, were significantly higher than those of the control group. In the present experimental conditions, exposure of local rabbits to chronic heat stress could induce some changes to biological, physiological, and biochemical parameters leading to altered growth performance.
