چکیده
BACKGROUND: The degree to which the amount of an
ingested nutrient is absorbed and available to the body is called
bioavailability. OBJECTIVES: Relative effectiveness of herbal
methionine (H-Met®) compared to DL-methionine (DL-Met)
was investigated in this experiment. METHODS: Exponential
regression analysis was used to determine bioefficacy of H-Met®
based on body weight gain, feed intake and feed conversion. DLMet
and H-Met® were added to a basal diet in 3 and 4 levels,
respectively, in starter, grower and finisher periods. Therefore,
that met the nutrient and energy requirements of broiler chickens,
with the exception of Met+Cys. RESULTS: In the 42-d trial,
broilers growth increased significantly (p<0.05), relative to
those broilers fed basal diet, regardless of Met sources. Carcass
characteristics did not respond significantly to the supplemental
Met. CONCLUSIONS: Regression analysis revealed that H-Met®
was 52% (body weight gain), 72% (feed intake) and 77% (feed
conversion ratio) as efficacious as DL-Met. H-Met® can be
administered as a new and a natural source of Met in poultry
industry.
