Effects of housing systems and glucose oxidase on growth performance and intestinal health of Beijing You Chickens.

ABSTRACT: We investigated the effects of housing systems and dietary glucose oxidase (GOD) on the growth performance and intestinal health of Beijing You chickens (BYC). The experiment was designed as a factorial arrangement of 2 housing systems × 2 dietary treatments. Chickens were fed a basal diet or a diet with 200 U/kg GOD and were reared on the floor with deep litter or in the cages. Compared with the litter floor groups, the decreased average daily feed intake of 1 to 42 d, decreased feed conversion ratio (FCR), improved average daily gain of 42 to 77 d, and the whole period were identified in the cage rearing groups (P < 0.05). The FCR of 42 to 77 d and the whole period, the 42-d ileal pH, and 77-d jejunal and ileal pH decreased with the supplement of GOD (P < 0.05). Additionally, 16S rRNA ge
