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 کاملEffects of Phytosterols on Growth Performance and Fat Metabolism in Broilers
The purpose of this study was to investigate the effects of diet supplemented with different levels of phytosterols (PS) on growth performance and lipid metabolism in broilers. A total of four hundred 1-day-old chicks (female: male =1:1) were randomly assigned into 4 treatments, each of which replicated 5 times with 20 chicks per replicate. Birds were fed with a basal diet without any additive ...

متن کاملThe Relative Effectiveness of Liquid Methionine Hydroxy Analogue Compared to DL-methionine in Broilers
The present experiment was conducted to assess the efficacy of liquid methionine hydroxy analogue-free acid (MHAFA) in comparison to DL-methionine (DL-Met) in broilers. 567 day-old Avian chicks were divided into 7 treatments with 5 replicates of 16 birds each. During the 35d (7-42 d) experimental periods chicks were given two basal diets. From 7 to 21d of age, a starting basal diet containing 1...
متن کاملComparative metabolism of L-methionine, DL-methionine and DL-2-hydroxy 4-methylthiobutanoic acid by broiler chicks.
1. Metabolism, in broiler chicks, of DL-2-hydroxy 4-methylthiobutanoic acid (DL-HMB), DL-methionine and L-methionine was compared in vivo using 14C-labelled tracers. 2. The distribution of L-[1-14C]methionine and DL-[1-14C]HMB in the major body tissues was examined for a period of 120 min after administration. 3. The relative oxidation (14CO2 exhaled), excretion and incorporation into tissue pr...
