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 func-tions and histology. Six hundred and forty Cobb 500 broiler chickens were randomly assigned to eight dif-ferent 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 supple-mentation (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 he-patic 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.
