Fig. 1From: Changes in the gut microbiota mediate the differential regulatory effects of two glucose oxidases produced by Aspergillus niger and Penicillium amagasakiense on the meat quality and growth performance of broilersEffects of two different types of GODs and AGPs on the growth performance (a) and intestinal enzyme activities (b) of 21-day-old and 42-day-old broilers. Note: CON indicates the control group, AGP represents the data from broilers fed antibiotic growth promoters, and GOD-P and GOD-A represent the data from broilers fed GOD produced by Aspergillus niger and Penicillium amagasakiense respectively. ADG: average daily weight gain; ADFI: average daily feed intake; FCR: ratio of feed to gain; 1 except for FCR, which has no unit, the unit of other indices in (a) are all expressed in gramsBack to article page
