The effect of intraperitoneal injection of vitamin C on feed intake and blood metabolites of Kermani sheep in severe heat stress

Heat stress is one of the stressors in livestock. Vitamin C has antioxidant properties and can help reduce heat stress ether. This study aimed to investigate the effect of intraperitoneal injection of vitamin V during acute heat stress on feed intake and some blood metabolites of Kermani sheep. This study was performed in Shahid Beheshti Research Station of Jiroft University under super-acute heat stress for three days. Treatments included male and female sheep divided into four treatments and five replications, so the treatments differed in sex and drug intake. The drug was injected at zero hours, and feed intake was measured at two and four hours after injection. Finally, blood samples were taken from the venous vein in the fourth hour after the drug injection. Serum samples were sent to the laboratory for analysis of blood metabolites. The results showed that intraperitoneal vitamin C injection significantly reduced feed intake (P <0.01). Albumin, cholesterol, and triglyceride metabolites were reduced (P <0.01) by vitamin C injection. However, vitamin C was reduced. There was no effect on total protein, glucose, creatine, and blood urea at the level of (P <0.05). The results showed that vitamin C reduced heat stress in sheep and improved physiological status and hormonal and blood parameters.
