Feed additive for improving disease resistance of laying ducks

Abstract

The invention relates to a feed additive for improving the disease resistance of laying ducks. The feed additive is prepared from, by mass, 50-60 parts of corn starch, 1-2 parts of donkey-hide gelatin, 10-12 parts of edible gelatin, 12-13 parts of oat, 3-5 parts of fructus lycii, 1-2 parts of radix angelica sinensis, 1-2 parts of mother wort, 5-8 parts of Angela yeast, 15-20 parts of glycerite, 1-2 parts of lactobacillus delbruckii fungicide, 1-2 parts of lactobacillus bulgaricus fungicide, 1-2 parts of chelated minerals and 1-2 parts of the root of red-rooted salvia. Through the experiment, by means of the feed additive for improving the disease resistance of the laying ducks, the disease occurrence rate of the laying ducks can be effectively reduced. When the laying ducks are fed with existing laying duck feed, the disease occurrence rate of the laying ducks 100-300 days old reaches up to 3.8%, but when the laying ducks are fed with the feed additive, the disease occurrence rate of the laying ducks is reduced to 1.2% or below, the breeding risk of farmers is greatly reduced, and the feed additive is worthy of use and popularization.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed additive for improving disease resistance of laying ducks. Background technique [0002] Female ducks are called laying ducks from the beginning of laying eggs until they are eliminated. Female ducks are called laying ducks from the beginning of laying eggs until they are eliminated. Generally, the utilization period of shelduck ducks for eggs is about 350 days (150-500 days old), which is called the first egg-laying year; The production performance is declining year by year, so it is not suitable to keep it. [0003] In order to ensure the egg production rate of laying ducks, when to release ducks, when to feed, and when to rest, are strictly implemented in a certain order. If the number of feeding meals is changed, and the type of feed is greatly adjusted, it will affect the physiological function of ducks. , resulting in reduced or discontinued production. However, if ...

AI Technical Summary

Problems solved by technology

Generally, the utilization period of egg-type shelduck is about 350 days (150-500 days old), which is called the first egg-laying year; there are also some ducks that can be used in the second or third year after moulting and rest, but other The production performance is declining year by year, so it is not suitable to keep it

[0003] In order to ensure the egg production rate of laying ducks, when to release ducks, when to feed, and when to rest, are strictly implemented in a certain order. If the number of feeding meals is changed, and the type of feed is greatly adjusted, it will affect the physiological function of ducks. , resulting in reduced or discontinued production

However, if the laying duck is sick, it will not only affect its own egg production, but it is also very likely to infect the laying duck in the same duck house, causing huge economic losses for the farmers.
