Table 3 Optimum Api-PR19 levels in broiler chickens on regression equation (mg/kg)

From: A novel apidaecin Api-PR19 synergizes with the gut microbial community to maintain intestinal health and promote growth performance of broilers

Regression equation R2 P-value Optimum levels, mg/kg
y = 2.321–0.003x + 6.729E-6 × 2 0.325 0.029 222.9
  1. Note: x represents the optimum levels of Api-PR19, y represents the ratio of feed intake to weight gain (FCR) of the broilers
