What is the effect of KiFAY on IGF-1 and protein accretion in broilers?

What is the effect of KiFAY on IGF-1 and protein accretion in broilersA 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 in-take 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.

Ileal Amino Acid Digestibility

Ileal Amino Acid Digestibility

Kifay, the natural amino acid optimiser is the product to watch as it has the capability to enhance the ileal amino acid digestibility due to the specific natural ingredients in its composition.

Amino acid supplementation in poultry is considered as an essential part of poultry nutrition. Methionine is the first limiting amino acid in poultry important for optimum growth, feed conversion and immunity. The protein nutrition is directly related to the illeal amino acid digestibility; this term can be divided further into apparent illeal amino acid digestibility or true amino acid digestibility.

The debate is already on as to what type of digestibility is to be considered while making a feed formulation; although it is undeniable that digestibility of protein is utmost important and all digestible amino acid systems are superior to use of total amino acid system in feed formulation.

The amino acids contained in feed-stuffs are not fully available to animal. It is therefore more efficient to formulate diets using values for digestible amino acids rather than total amino acids. The optimisation of amino acid supply leads to increased animal performance and, because the ingested protein is better balanced for animal’s requirements, nitrogen excretion is reduced.
