COMPOSITION OF ASSORTED FEED HAVING RESISTANCE OF HEAT STRESS FOR BROILER

摘要

The present invention relates to a formulated feed composition for broiler having a resistance effect against the heat stress, and a boiler breeding method reducing the heat stress of broiler using the same. The formulated feed composition for broiler according to the present invention is able to effectively decrease heat stress of broiler by a mechanism of stimulating the cell proliferation of immune system to increase secretion of blood immune substances, decreasing corticosterone, which is a stress hormone, maintaining an appropriate acidity of caecum to accelerate growth of beneficial microorganisms and to inhibit growth of harmful microorganisms, and improving the growth ability of broiler. The breeding method of broiler according to the present invention follows a step of feeding fodder with different compositions according to the growth step of broiler, and is able to effectively alleviate the heat stress of broiler by turning off the light for 12 hours, and feeding at a specific time in order to minimize the heat stress due to metabolic heat generation of broiler under heat wave, in particular. As such when the formulated feed and a breeding method according to the present invention are used, the productivity of broiler is able to be improved by increasing the tolerance of broiler against heat stress (immune cell activation, stress hormone reduction, caecum microorganism colony maintenance, etc.) in the high temperature heat wave condition.
