Preparation method of meat duck feed

Abstract

The invention relates to a preparation method of a meat duck feed. The preparation method comprises the following steps of performing superfine crushing on medicated leaven, endothelium corneum gigeriae galli, heartleaf houttuynia herbs, radix angelicae dahuricae, haws and maifan stone powder, adding water, performing soaking for 4-6 hours, performing decoction, then performing filtration, and concentrating filtrate in a 5-6-fold manner so as to obtain a concentrated solution; uniformly mixing corn with soybean meal, bran, bone meal and fish meal, and performing superfine crushing so as to obtain a mixture A; adding the concentrated solution to the mixture A, performing uniform stirring, then performing heat preservation at 86-90 DEG C for 40min, then adding alum powder, performing uniformstirring, continuing performing heat preservation at 65-70 DEG C for 1-2h, and after heat preservation is completed, performing cooling to room temperature so as to obtain a mixture B; and adding calcined oyster shell powder to the mixture B, performing uniform stirring, performing heat preservation, then adding composite vitamins and composite minerals so as to obtain a granulated feed namely the meat duck feed. Through the feed prepared through the preparation method disclosed by the invention, meat ducks can obtain enough nutrients, and the growing performance and the immunity of the meatducks can be improved.

Description

technical field [0001] The invention relates to a feed, in particular to a method for preparing a duck feed for meat. Background technique [0002] The final peak period of meat-type ducks from brooding to absolute weight gain is about 50 days at the age of 7 weeks, and then gradually declines. Some meat-type duck feeds are not formulated according to the growth stage and weight gain characteristics of meat-type ducks and the development trend of the body. Growth and development, and inhibit immune function, leading to decline in power and the occurrence of certain poultry diseases, which increases the treatment cost of poultry diseases; some feeds have excessive nutrients, exceeding the body's needs, resulting in excessive waste, increasing breeding costs, reducing profits and economics benefit. Moreover, some feeds are not conducive to the development of duck breeding production due to their complex chemical composition, high cost, and unclear side effects. Therefore, r...
