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

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

Regression equation	R²	P-value	Optimum levels, mg/kg
y = 2.321–0.003x + 6.729E-6 × 2	0.325	0.029	222.9

Note: x represents the optimum levels of Api-PR19, y represents the ratio of feed intake to weight gain (FCR) of the broilers
