NGXUMESHE, A.M.  y  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.

Palabras clave : TXAP; broiler performance; exogenous composite enzymes; maize-soybean feeds.
