"An experiment with broiler chickens was conducted to compare the relative bioavailability of liquid methionine hydroxy analogue free acid (MHA-FA) with that of DL-methionine (DLM) during fattening to 35 days of age. Ross 308 male chicks were allotted to 9 treatments, each consisting of six replicates of 140 birds/pen. Four graded levels (0.04, 0.08, 0.16, and 0.28 %) of MHA-FA or DLM products (weight/weight comparison) were added to a maize-wheat-soyabean meal basal diet deficient in sulphur amino acids. Using a multi-exponential model describing the dose-response relationships, the bioavailability estimates of MHA-FA relative to DLM were 68, 70, 52 and 57 % on a weight-to-weight basis and 77.7, 79.0, 59.3 and 64.6 on equimolar basis for body weight, feed conversion, carcass yield and breast meat yield, respectively. The bioavailability of MHA-FA for carcass yield and breast meat yield was significantly (P < 0.05) lower than that of DLM."@en . "Heger, Jaroslav" . "S" .
