1. The net absorption and the biological efficacy of DL-methionine and of DL-methionine hydroxy analogue free acid (MHA-FA) were evaluated in chickens under heat stress. 2. In a growth assay, finishing broilers 21 to 42 d of age were fed on diets containing graded amounts of the two supplements; the basal diet was composed of practical ingredients. 3. From slope-ratio analysis, equimolar efficacy of MHA-FA relative to DL-methionine was determined to be 83% (confidence limits 61 to 115%) from… CONTINUE READING
