Preparation method for feed used for meat type duck

Abstract

The invention provides a preparation method for a feed used for a meat type duck. The preparation method comprises the following steps: subjecting medicated leaven, inner membrane of chicken gizzard, heartleaf houttuynia herb, dahurian angelica root, hawthorn fruit and Chinese medical stone powder to ultramicro crushing, then carrying out soaking in water for 4 to 6 h, carrying out filtration after decoction and subjecting obtained filtrate to 5 to 6 times concentration so as to obtain a concentrate; uniformly mixing corn, soybean meal, wheat bran, bone meal and fish meal and carrying out ultramicro crushing so as to obtain a mixture A; adding the concentrate into the mixture A, carrying out uniform mixing under stirring, then maintaining an obtained mixture at a temperature of 86 to 90 DEG C for 40 min, adding alum powder, carrying out uniform mixing under stirring, continuing maintaining an obtained mixture at a temperature of 65 to 70 DEG C for 1 to 2 h and carrying out cooling to room temperature after completion of temperature maintenance so as to obtain a mixture B; and adding calcined oyster shell powder into the mixture B and adding composite vitamin and composite mineral matters after uniform stirring and temperature maintenance so as to prepare a granular feed, i.e., the feed for the meat type duck. The feed prepared in the invention enables meat type duck to obtain enough nutrients and can improve growth performance and immunity of young meat type duck.

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, ...
