    Effect of Herbal Methionine Supplementation on Feet Intake, Weight Gain and Feed Conversion Ratio of Broiler Chicken
    (Uva Wellassa University of Sri Lanka, 2012) Nanayakkara, K.G. M. D; B u lu mulla, P. B. A. L. K; Gu nath ilake, C
    The broiler industry has developed all over the world during past few decades and the production of poultry meal and other products leave been significantly increased in Sri Lanka with the last few years. The requirement of nutrients for broilers is higher than the other livestock animals. One of the most important areas is amino acid nutrition. Of the essential amino acids required for poultry, methionine is usually first limiting in diets based on maize and soya bean meal. It is more economical to add methionine than more soda bean real or other natural protein to meet the requirement (Holder and Roy, 2007). Methionine is an indispensable amino acid, must be supplied in the diet of the chicken, as the poultry birds are unable to synthesise it in the amounts necessary to sustain life and growth the supplementation of broiler feeds with this amino acid is very common in the poultry industry. However, synthetic Methionine is metabolized into higtily toxic compounds such as methyl propionate, trim ethylamine there by adversely altering the performance of poultry birds (Ha I der and Roy, 2007). Recently the use of synthetic Methionine has been questioned and their use is becoming restricted in many regions of the world. Therefore, there is renewed interest in developing natural alternative suppliants to in an intern an into I performance and wellbeing. Herbal Methionine is a unique poultry feed supplement, which contains Methionine in a natural and bio active form as a readily digestible composition along with the enzyme activity (Kanduri and others, (2011). Herbal Methionine as a source of ‘active Methionine’ is c fainted to be effective in its optimum activity for proper broiler accretion and other functions in poultry birds so that they can reach better growth and performance potential (Halder and Roy, 2007). Methionine deficiency leads to poor feed Conversion Ratio (FCR) and retarded growth in chicken. In this experiment a comparative study on the performance of coi11mercial broiler chicks (Hubbard Flex) bed a ration with DL- n4elhioninc and fed with DL Methionine was carried out.
