dc.description.abstractA biological experiment was carried out for 6 weeks at the Poultry Research Station, TANUVAS, Chennai, India to investigate the effect of replacing synthetic DL-methionine by herbal methionine at different levels on the production performance of commercial broilers. 300 day-old broiler chicks (Cobb400) were assigned randomly in to five treatment groups each with six replicates of 10 birds each and fed with one of the following experimental diets viz., Control basal diet (T1), basal diet was supplemented with DL Methionine @ 2 Kg/tonne of feed (T2), DL Methionine1.33 Kg + herbal methionine @ 0.67 Kg/tonne of feed (T3), DL-methionine1Kg + herbal methionine 1Kg/tonne of feed (T4), DL-methionine 0.67 Kg + herbal methionine @ 1.33 Kg/tonne of feed (T5). The birds were provided with feed (BIS 2007) and water ad libitum. Data were recorded and analyzed by one-way ANOVA procedure of SPSS software. Results revealed that the body weight was significantly (P≤0.01) increased at 50 and 67% replacement of DL–Methionine. Feed consumption was significantly affected by the herbal methionine. DL-methionine at 67% replacement by herbal methionine significantly (P≤0.05) improved feed conversion ratio in broilers. Serum methionine and cysteine levels were significantly (P≤0.05) increased in groups in which DL-methionine was replaced by herbal methionine 50 and 67% level. Supplementation of herbal methionine had significant (P≤0.05) effect on relative weight of liver, gizzard, and heart however the length of intestine was not affected. Similarly carcass traits and sensory quality of the meat were not affected by dietary treatments. Herbal methionine at 50 and 67% replacement levels improved livability and reduced cost of production per kg of live weight in broilers.en_US
