Embodiment 1

[0038] The experiment adopts a single-factor experiment design. The experiment selects ducks with similar body weight, healthy and peak laying period. They are randomly divided into 5 treatments, each treatment has 10 repetitions, and each repetition has 50 ducks. The five treatment groups are: control group, treatment 1, treatment 2, treatment 3 and treatment 4 (this case). The control group was fed with a certain manufacturer's diet on the market, and the treatment 1, treatment 2, treatment 3, and treatment 4 groups were fed with 4 kinds of self-made diets. Experimental stage: 180 days to 330 days. The experimental ducks were reared in captivity, and were reared repeatedly. Open and close the door of the duck house at 6:30 and 17:30 every day, 16 hours of light per day, natural ventilation, regular feeding at 7:00, 12:00, 17:00, free drinking water; 8:00, 17:30 Collect duck eggs regularly, check the health status of duck flocks, and clean and disinfect regularly. The feed...

Embodiment 2

[0057] The experiment adopts a single-factor experiment design. The experiment selects ducks with similar body weight, healthy and peak laying period. They are randomly divided into 5 treatments, each treatment has 8 replicates, and each replicate has 60 ducks. The five treatment groups are: control group, treatment 1, treatment 2, treatment 3 and treatment 4 (the embodiment of the present invention). The control group was fed with a certain manufacturer's diet on the market, and the treatment 1, treatment 2, treatment 3, and treatment 4 groups were fed with 4 kinds of self-made diets. Experimental stage: 180 days to 330 days. The feeding and management mode of test duck is the same as embodiment 1. The feed formula is shown in Table 5.

[0058] The test laying duck was 330 days old, and 6 laying ducks that were close to the average body weight of the repetition of the treatment were taken out from each repetition of each treatment group. After weighing its individual weight...

Abstract

The invention relates to compound feed for laying ducks, in particular to compound feed capable of reducing oxidative stress of laying ducks as well as a preparation method and an application of the compound feed. The compound feed comprises components in percentage by weight as follows: 5%-10% of rapeseed meal, 5%-10% of corn DDGS, 5%-10% of rice bran, 30%-60% of corn, 8%-13% of stone powder, 2%-8% of dried brewer's grains, 5%-20% of soybean meal, 0%-15% of barley, 1.5%-1.5% of a premix, 0%-0.05% of zeolite powder, 0.1%-0.5% of red date powder, 0.01%-0.05% of saccharicterpenin, 0.01%-0.05% oftaurine, 0.01%-0.05% of vitamin E and 0.05%-0.2% of arginine monohydrochloride. The immunity and laying rate of the laying ducks can be directly improved by solving the oxidative stress problem.

Description

technical field [0001] The invention relates to a compound feed for laying ducks, in particular to a compound feed for reducing oxidative stress of laying ducks, a preparation method and application thereof. Background technique [0002] Oxidative stress is a process in which the animal body responds to the internal and external environment, conducts multi-level stress regulation and signal transduction on the body through redox reactions, and causes oxidative damage at the same time. Under normal circumstances, the oxidation-reduction reaction in the animal body is in a dynamic equilibrium process. Although there are free radicals in the body at this time, the animal will remove free radicals through the self-regulation process of the body, and will not have a major impact on the animal body. However, when the animal body is affected by certain factors, for example: ①Environmental factors: overcooling, overheating, excessive ammonia in the air, noise. ② Feed factors: feed ...
