the performance, antioxidant status, blood chemistry analysis and tissue histology of broiler birds fed a diet containing chromium picolinate and vitamin c

This study looks into the effects of supplementing broiler chickens with chromium picolinate (crpic) and vitamin c on their efficiency and antioxidant status without interfering with their essential metabolic functions and histology. six hundred and forty cobb 500 broiler chickens were randomly assigned to eight different dietary treatments, each with ten birds. diets 1 to 8 were produced from a base diet that was divided into eight equal parts. diets 1 to 4 were supplemented with 0 mg/kg crpic, 0.4 mg/kg crpic, 0.8 mg/kg crpic, and 1.2 mg/kg crpic, respectively. supplements of 200 mg/kg vitamin c, 0.4 mg crpic and 200 mg vitamin c, 0.8 mg crpic and 200 mg vitamin c, and 1.2 mg crpic and 200 mg vitamin c were given to the diets 5 to 8. performance, carcass analysis, antioxidant parameters, serum-biochemistry, and histology were all investigated. dietary supplements of 0.8 mg/kg crpic and 200 mg vitamin c improved body weight gain, feed conversion ratio, slaughtered weight, and antioxidant enzyme status. dietary vitamin c supplementation (200 mg/kg) reduced aspartate aminotransferase and alanine aminotransferase, while dietary crpic supplementation (1.2 mg/kg) reduced blood glucose. however, dietary supplementation with 0.4 mg/kg crpic decreased abdominal fat, while 1.2 mg/kg crpic supplementation resulted in substantial hepatic inflammation and interstitial nephritis. in broiler development under tropical conditions, a mixture of 0.8 mg/kg crpic and 200 mg vitamin c dietary supplementation is advanced.
