[ 1 ] - Bioavailability comparison between herbal methionine and DL-methionine on growth performance and immunocompetence basis in broiler chickens

BACKGROUND:Herbal methionine can be compared relative toDl-methionine with evaluation of bioavailability of this source ofmethionine. OBJECTIVES: An experiment was carried out todetermine the relative bioefficacy of herbal methionine (H-Met)®relative to DL-methionine (DL-Met) on performance criteria andimmunocompetence of Met sources in male broilers. Atotal of 160male broilers were fed a Met-d...

[ 2 ] - Relative effectiveness of herbal methionine compared to DLmethionine on growth, performance and carcass responses basis in broiler chickens

BACKGROUND: The degree to which the amount of aningested nutrient is absorbed and available to the body is calledbioavailability. OBJECTIVES: Relative effectiveness of herbalmethionine (H-Met®) compared to DL-methionine (DL-Met)was investigated in this experiment. METHODS: Exponentialregression analysis was used to determine bioefficacy of H-Met®based on body weight gain, feed intake and feed c...

[ 3 ] - Bio-efficacy comparison of herbal-methionine and DL-methionine based on performance and blood parameters of broiler chickens

This study was conducted to compare the bio-efficacy of herbal methionine (H-Met) relative to DL-methionine (DL-Met) on 160 “Ross 308” broiler chickens. DL-Met and H-Met were added to the basal diet in eight experimental treatments with three and four concentrations respectively in starter, grower and finisher period. Blood parameters which were measured at 24 and 42 days of age consisted of: s...
