NGXUMESHE, A.M. e GOUS, R.M.. Effects of varying levels of thermostable xylanase, amylase and protease (TXAP) composite enzyme supplement on body growth of broiler chickens. S. Afr. j. anim. sci. [online]. 2009, vol.39, n.5, pp. 312-315. ISSN 2221-4062.
A dose-response experiment was conducted with Ross broiler chickens from day-old to 42d of age to determine the effect of exogenous composite enzyme (TXAP) on broiler performance and the most beneficial rate of inclusion. Broiler chickens were fed maize-soyabean based feed with one diet unsupplemented and five other diets supplemented with increasing levels of TXAP, from 0.5 to 2.5 g/kg. The inclusion of TXAP did not have any significant improvement on broiler performance. The lack of response in this experiment might be due to the quality of ingredients used.
