Anais da Escola de Agronomia e Veterinária, Goiânia, v. 7, n. 1, p. 53-64, jan./dez. 1977. Disponível em: <https://www.revistas.ufg.br/pat/article/view/2270>.1517-6398http://repositorio.bc.ufg.br/handle/ri/11856Two triala were conducted at Laboratqrio de Enzimologia do Instituto de Ciências Biológicas (I.C.B.) and Departamento de Zootecnia da Escola de Agronomia e Vet􀀬 rinária da Universidade Federal de Goiás, to detennine: a) Influence of xylanase (fungic prepara- tions} in poultry rations fed to rats. b) Possibility to use xylanase to improve conunercial rations to monogastrics. A total of 48 rats were randomized in 12 m􀇱 talic cages in an experimental design with 4 treatments and 3 repetitions. The treatments used were: Trial 1 : T - Conunercial ration to broilers (table II). A - Conunercial ration + 0,02% of xylanase. B - Commercial rations + 0,04% of xylanase. C - Commercial ration + 0,06% of xylanase. Trial 2 - As trial 1, but the levels of xy­lanase were 0,1, V,2 and 0,4% {treatment A,B and C, res­pectively). The following conclusions are presented: a) Increasing levels of xylanase didn't improve weight gains, feed Comsumption and feed gain b) Different levels of crude fiber and xy lanase should be studied in other experiments.porAcesso AbertoArtigo
