Comparative effects of dl-methionine and n-methionine on growth performance and biochemical parameters of broilers

Methionine is essential for various vital functions in body such as: protein synthesis, regulation of cell division, methyl donor, reduces reactive oxygen species etc. it also helps in enhancing overall growth performance, feed efficiency utilization and livability in broilers. Synthetic methionine is metabolized into highly toxic compounds such as methylpropionate, thereby, adversely altering the performance of poultry birds. Synthetic methionine is listed among the prohibited synthetic substances and its usage has been questioned in organic farming practices. Therefore, there is great renewed interest in developing natural alternative supplements to maintain animal performance and well being. The aim of the present experimental study is to evaluate efficacy of herbal formulation N-Methionine (Natural Herbs & Formulation, India) and synthetic methionine in improving overall growth, productivity and performance in poultry birds. In this study we concluded that supplementation of N- Methionine (herbal methionine manufactured by Natural Herbs and Formulation Pvt. Ltd. India) can replace synthetic DL-Methionine as evident by the comparable bird’s growth, viability, biochemical parameters.
