Due to the lack of functional sweat glands, rabbits find it difficult to release excess heat under high-temperature conditions, resulting in heat stress. This high-level temperature condition leads to substantial damage to growth performance and intestinal health resulting in significant financial losses for the meat rabbit industry. This study found that adding betaine (Bet) to the diet can improve the growth performance and intestinal barrier integrity of heat-stressed growing rabbits, which may be related to improving intestinal antioxidant capacity and immune status. 1.5 g Bet/kg diet group showed better effects than 0, 0.75, 1.0, and 2.0 g Bet/kg diet groups in improving growth performance and intestinal health of heat-stressed growing rabbits.
