|Title:||Biopotency of methionine sources and their effects on sexual maturity of growing Japanese quail.||Authors:||Shim, K.F.
|Issue Date:||Jun-1990||Citation:||Shim, K.F.,Chen, E.V. (1990-06). Biopotency of methionine sources and their effects on sexual maturity of growing Japanese quail.. British poultry science 31 (2) : 273-282. ScholarBank@NUS Repository.||Abstract:||1. Japanese quail were fed on practical diets supplemented with graded amounts of DL-methionine (DL-M), DL-methionine-sodium (DL-M-Na), DL-methionine hydroxy-analogue calcium (DL-MHA-Ca) and DL-methionine hydroxy-analogue free acid (DL-MHA-FA) on an equimolar basis. 2. By the slope ratio assay using quail growth as the criterion, it was deduced that the biological activity of DL-M-Na, DL-MHA-Ca and DL-MHA-FA was approximately 0.96, 0.72 and 0.84 that of DL-M on an equimolar basis. 3. On a weight basis of the commercial products, the efficacies of DL-M-Na, DL-MHA-Ca and DL-MHA-FA were 0.38, 0.62 and 0.74, respectively. 4. Quail fed on the diet with the highest content of methionine had greater ovary weight, oviduct weight, oviduct length and egg production.||Source Title:||British poultry science||URI:||http://scholarbank.nus.edu.sg/handle/10635/106758||ISSN:||00071668|
