Abstract
The invention discloses a feed formula for resisting the heat stress of broilers. According to the feed formula, dry fly maggot powder in an amount which is 1 to 3 percent based on the weight of a basal feed and a ginkgo leaf extract Egb761 in an amount which is 0.1 to 0.3 percent based on the weight of the basal feed are added into the basal feed. According to the feed formula, the fly maggot powder is rich in protein and essential amino acid, and can enhance the disease-resistant and stress-resistant capacity of the broilers while improving the growth performance of the broilers; and ginkgo leaves and the ginkgo leaf extract thereof have rich ginkgo flavone and terpene lactones, and have an anti-oxidative stress effect. In addition, the ginkgo leaves and the ginkgo leaf extract thereof also improve the growth capacity and disease-resistant capacity of the broilers and improve the quality of chicken.
Description
Technical field [0001] The invention belongs to the technical field of feed formulas, and specifically relates to a feed formula for resisting heat stress of broilers. Background technique [0002] Heat stress is a strong stress for broiler chickens, and it is one of the important causes of chicken stress. It is generally believed that 10-32℃ is a normal environment for chickens to maintain normal body temperature. 21-26℃ is the comfortable environment temperature range for chickens to survive. Broilers can exert the best growth performance. 26-32℃ is the temperature range where chickens are not comfortable but can maintain normal physiological functions, and higher than this temperature range will cause chickens Physiological dysfunction, and even death, we call this phenomenon heat stress. The number of chicken deaths and economic losses caused by heat stress around the world are alarming. [0003] With the continuous development of animal husbandry, the demand for protein is ...
