Problems solved by technology

Traditional laying duck breeding is mainly based on fish and duck polyculture and free-range breeding on the ground. With the improvement of people's requirements for environmental quality and livestock and poultry product quality, the traditional laying duck breeding method that relies on environmental resources has gradually appeared irregular management, manure Disadvantages such as non-standard pollution, high labor intensity, low production level and economic benefits have hindered the healthy development of the laying duck industry. With the maturity of cage laying hen breeding technology, cage laying ducks have also been applied.
However, due to the long-term inability to play and bathe in cages, the egg ducks have fluffy feathers, ugly appearance, difficult depilation, and poor meat quality, which affect the selling price of the eliminated egg ducks.

Embodiment 1

[0025] The embodiment of the present invention provides a method for improving the meat quality of caged ducks, comprising the following steps:

[0026] (1) Group management: The caged ducks are grouped according to their body weight and physical strength, and they are raised in a flat duck house on the ground, at a rate of 4 / m 2 The stocking density is divided into relatively independent rearing units, with 500 in each rearing unit, and the laying ducks with poor physique are excluded;

[0027] (2) Adaptive feeding: The grouped ducks are adaptively reared in the duck house for 7 days. During the adaptive feeding period, the feed, feeding frequency and feeding amount are the same as those before caged elimination, so that the laying ducks gradually Adapt to the ground level environment;

[0028] (3) Restricted feeding: The laying ducks that have been adapted to feeding are restricted to feeding in the duck house for 7 days. During the restricted feeding period, the normal fee...

Embodiment 2

[0033] The embodiment of the present invention provides a method for improving the meat quality of caged ducks, comprising the following steps:

[0034] (1) Group management: The caged ducks are grouped according to their body weight and physical strength, and they are raised in a flat duck house on the ground, at a rate of 6 / m 2 The stocking density is divided into relatively independent rearing units, each of which is 600, and the laying ducks with poor physique are excluded;

[0035] (2) Adaptive feeding: The grouped ducks are adaptively reared in the duck house for 7 days. During the adaptive feeding period, the feed, feeding frequency and feeding amount are the same as those before caged elimination, so that the laying ducks gradually Adapt to the ground level environment;

[0036] (3) Restricted feeding: The laying ducks that have been adapted to feeding are restricted to feeding in the duck house for 7 days. During the restricted feeding period, the normal feed intake ...

Abstract

The invention provides a method for improving meat quality of cage-reared eliminated laying ducks, which comprises the following steps: feeding cage-reared eliminated laying ducks in a duck shed in groups according to the weight and physique strength, dividing the duck shed into independent feeding units according to the feeding density of 4-6 ducks / m<2>, and feeding 500-600 ducks in each feeding unit; adaptively feeding the grouped laying ducks in the duck shed for 7 days, and then restrictively feeding the laying ducks in the duck shed for 7 days; transitionally feeding he laying ducks subjected to limited feeding with ganoderma lucidum mushroom bran feed for 7 days, and enabling the laying ducks to freely eat after 7 days; and after transitional feeding, putting the laying ducks into a playground and a water playing pond to move freely every day in the daytime, and driving the laying ducks into the duck shed to have a rest at night, wherein the stocking period is not less than 60 days, the laying ducks are limited to move 15 days before the laying ducks appear on the market, and stocking movement is conducted for 4-5 hours every day. The method can improve the immunity of the cage-reared eliminated laying ducks, reduce the incidence rate of diseases, improve the conditions that the cage reared eliminated laying ducks are fluffy and disordered in feather, ugly in appearance and difficult to depilate, reduce the sebum rate of the eliminated laying ducks, and improve the meat quality, taste and flavor.

Description

Technical field: [0001] The invention belongs to the technical field of poultry raising, and in particular relates to a method for improving the meat quality of caged and eliminated laying ducks. Background technique: [0002] my country is a big country in the breeding and consumption of laying ducks, and the scale of the laying duck industry ranks in the forefront of the world. Traditional laying duck breeding is mainly based on fish and duck polyculture and ground free-range breeding. With the improvement of people's requirements for environmental quality and the quality of livestock and poultry products, the traditional laying duck breeding method that relies on environmental resources has gradually emerged. The disadvantages of substandard pollution, high labor intensity, low production level and low economic benefit hinder the healthy development of the laying duck industry. However, under the condition of caged ducks, due to the long-term inability to take a bath in ...
