Problems solved by technology

However, due to changes in the ecological environment and other factors, laying duck breeding in my country has gradually shifted from free-range and semi-captive breeding to intensive breeding in full captivity. The laying ducks have reduced the chance of obtaining natural pigments in the external natural environment, resulting in lighter egg yolks. And affect the commodity value of duck eggs

Embodiment Construction

[0018] A breeding method for raising egg production rate of laying ducks comprises the following specific steps:

[0019] (1) Feeding management:

[0020] When the laying ducks are 160 days old, start to gradually change the feed. On the first day, use laying duck feed to replace 8% of the original feed. After that, increase the feed for laying ducks every day, reduce the amount of original feed, and control the daily feeding amount. , complete refueling within 7 days;

[0021] When the egg production rate reaches 5%, gradually increase the feeding amount, add more oyster shells and green feed, and add 4g of feed per duck per day, until the egg production rate remains stable for 3 consecutive days, reaching the peak egg production period, control the daily feeding The amount of feeding remains unchanged, feeding 4 times a day, and feeding water from time to time to ensure sufficient drinking water;

[0022] When it is found that the egg production rate has decreased, add cod...

Abstract

The invention discloses a raising method for increasing the duck egg laying rate. Through reasonable material changing and adding and adding of algae powder in feed, the iodine content of duck eggs can be increased, the egg yolk color is darkened, the content of amino acids in added broccoli stem and leaf powder and citrus peel powder, high-quality protein resources are provided for laying ducks,colored matters including lutein and carotenoid of the duck yolk in the feed are improved, and the color and luster of the egg yolk are improved; in addition, a mildew inhibitor is added, the oxidization deterioration of the feed is prevented, and the color of the egg yolk is further kept; by increasing the illumination, the temperature of a duck shed is improved and meanwhile kept, it is avoidedthat the laying rate of the laying ducks is decreased due to the uneven temperature, the sex hormone secretion of pituitary glands of the laying ducks can be promoted, ovulation is accelerated, the egg producing period is prolonged, and the laying rate of the laying ducks is increased.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a raising method for raising egg production rate of laying ducks. Background technique [0002] Laying duck breeding and duck egg processing are traditional advantageous industries in my country. Salted duck egg yolk, which is bright in color, large in size, and rich in oil, has always been a favorite food for people. However, due to changes in the ecological environment and other factors, laying duck breeding in my country has gradually shifted from free-range and semi-captive breeding to intensive breeding in full captivity. The laying ducks have reduced the chance of obtaining natural pigments in the external natural environment, resulting in lighter egg yolks. And affect the commodity value of duck eggs. The pigment in egg yolk comes from the feed, and poultry cannot synthesize it by itself. It is mainly lipophilic oxygen-containing (hydroxyl, ketone-based) carotenoi...
