Fig. 3From: Growth performance, caecal microbiome profile, short-chain fatty acids, and litter characteristics in response to placement on reused litter and combined threonine, arginine and glutamine supplementation to juvenile male broiler chickensThe main effect of Litter treatment on the %G + C profile of caecal bacteria from broilers aged 21 days. In the upper panel, the solid blue line represents the mean %G + C profile of birds placed on clean litter and the solid red line represents the mean %G + C profile of birds placed on reused litter (n = 16). In the lower panel, the solid blue line shows the results from ANOVA and the solid red line marks the threshold of P = 0.05Back to article page
