LARA, Leonardo Boscoli et al. The peroxidation technique for methionine determination in derived samples of digestibility assays of the wheat and its by-products in broilers chickens. Ciênc. agrotec. [online]. 2005, vol.29, n.2, pp.459-466. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542005000200026.

One experiment was conducted with broiler chickens, for evaluation of metabolizable methionine and its levels in the wheat and some of its products, comparing two analyses techniques of methionine determination; hydrolyze and peroxidation with  performic  acid  before  hydrolyze.  The broilers  were  randomly distributed in factorial outline 2 x 4 x 8, (methods x treatments x feeds) with three repetitions. Seven feeds by-products of wheat grain were used in the four treatments. The first two treatments were set in the traditional methodology of ad libitum consumption and in the treatments three and four, the method of forced feeding was used. The treatment four were tested in the caecectomised chickens. The results of this experiment suggested that only the peroxidation with performic acid before hydrolyze showed good result in measure metabolizable methionine and its levels of wheat and its by-products.
