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...
متن کاملRelative effectiveness of methionine hydroxy analog compared to DL-methionine in broiler chickens.
Two broiler experiments were conducted to assess the relative bioefficacy of liquid DL-Met hydroxy analog-free acid (MHA-FA) and DL-Met (DLM). Exponential regression analysis was used to determine biological efficacy based on body weight, feed conversion, and carcass responses to dietary Met source. In Trial 1, four graded inclusion levels of DLM and liquid MHA-FA (0.06, 0.12, 0.18, and 0.24%) ...

متن کاملBiological Effectiveness of Methionine Hydroxy-analogue Calcium Salt in Relation to DL-Methionine in Broiler Chickens
Two feeding trials were conducted to assess the relative bioavailability (RBV) of methionine hydroxy analogue calcium salt (MHA-Ca) in comparison to DL-methionine (DL-Met). Male Ross 308 (1-38 days) and Cobb 500 chickens (1-42 days) were used in studies 1 and 2, respectively. Experimental diets based on wheat and soybean meal or sorghum and soybean meal were fed during three phases. In both exp...
متن کاملPathology of Bursae of Fabricius in Methionine-Deficient Broiler Chickens
The purpose of this 42-day study was to investigate the effects of methionine (Met) deficiency on immune function by determining the relative weight, morphological and ultrastructural changes of bursae of Fabricius, cell cycle, and apoptosis of bursa cells. One hundred and twenty one-day-old avian broilers were randomly divided into two groups and fed on a control diet (starter diet, Met 0.50%;...
