Hens fed the SDEW diet had significantly greater AH and HU compared to those fed the ORG diet in period 2 (P = 0.0122 and P = 0.0058 for AH and HU, respectively), compared to those fed the BNPP diet in period 3 (P = 0.0156 and P = 0.0051 for AH and HU, respectively) and period 4 (P = 0.0032 and P = 0.0026 for AH and HU, respectively), and compared to those fed both the ORG and BNPP diets overall (P = 0.0013 and P = 0.0005 for AH and HU, respectively) (Table 5). Albumen height and HU were significantly greater for periods 1 and 2 compared to subsequent periods and greater for period 3 compared to period 4 (P < 0.0001).
