A comparative study was performed to investigate the efficacy of KiFAY as a feed additive on performance parameters, thyroid, and pancreatic hormone levels in broilers. Ninety birds (Vencobb 400) were randomly divided into three groups viz., Control (no DL-methionine supplementation), Treatment 1 (containing added DL-methionine) and Treatment2 (containing KiFAY and without DL-methionine supplementation). The performance parameters (weekly body weight, body weight gain, feed intake, and feed consumption ratio) were recorded and calculated during the whole study of 4 weeks. Analysis of insulin and insulin-like growth factor (IGF1), triiodothyronine (T3), thyroxine (T4) and thyroid stimulating Hormone (TSH) were performed at the end of the study.
The results show that birds on supplementation of KiFAY performed significantly (p<0.001) better than other treatments. The weekly body weight, body weight gain, feed intake and feed consumption ratio improved in KiFAY treated birds. The study shows an increase in insulin and IGF1 levels (p<0.001) in KiFAY than other treatments. Serum T3, T4 and TSH levels in the treatment2 were higher than other treatments (p<0.001). The KiFAY supplementation was able to improve performance with associated responses at a hormonal level in broilers.
