Diet of Ho crossbred broiler chickens aged from 30 to 100 days old were supplemented with leopard lily’s powder at the rates of 0.25% and 0.5%, chickens in the control group of the same age were not supplemented with this powder and raised in the same condition. The results showed that the supplementation with the rate of 0.25% and 0.5% of leopard lily’s powder in chicken diets had similar effectiveness in disease prevention and treatment. Leopard lily’s powder added to the diets of broilers not only limits the incidence of respiratory and digestive diseases in chickens but also reduces the number of days of treatment at different age stages (P <
0.05). Chickens fed diets supplemented with leopard lily’s powder had higher weight gain compared with control chickens from 99.6 - 112.6 g/head. Moreover, leopard lily’s powder does not affect the physiological parameters of blood in chickens.
