Problems solved by technology

[0002] In the production of laying hens, due to the monotonous environment of the current chicken cages and the lack of natural environments such as laying nests, sand, and habitats under natural conditions, laying hens will lie on their nests, sand bath, scratch and normal habitats. Resting, pecking behavior is difficult to express, so the welfare level of layers in layer cages is very low

Embodiment 1

[0016] see figure 1 , a chicken cage for improving the welfare level of laying hens, which includes a chicken cage body 1, and the chicken cage body 1 separates an egg production area a and a rest area b through a door curtain 2, and the egg production area a is a whole A square box body is provided with a perches cross bar 3 horizontally in the box body, and the two ends of the cross bar 3 are respectively fixed on the two ends of the box body, and several thin ropes 4 are hung on the top of the rest area b. Foot pads 5 and sand bath trays 6 are laid on the bottom of the rest area b, pecking pads 7 are respectively provided on the left side and the middle of the rest area b, and straw 8 is laid on the bottom of the egg-laying area a.

[0017] The chicken coop is divided into egg-laying area a and rest area b. The length is 2 meters and the width is 60 cm. The egg-laying area a is a square wooden box with a length and width of 60 cm. Straw 8 is laid inside, and there is a door...

Embodiment 2

[0019] In this example, Hailan white-feathered laying hens were selected as experimental animals. From the age of 0 weeks, 300 Hailan white feather hens were raised. The formal test started from the first week of age, randomly selected 300 laying hens with uniform weight and strong body, and randomly divided them into 20 groups, with 15 chickens in each group. Among them, 10 groups were raised in the welfare-type chicken cages, and 10 groups were raised in traditional chicken cages. Using traditional chicken cages, only drinking water and feed are provided, without foot pads, peck pads, perch bars, sand tables, and hanging strings. In the brooding period, a comparative experiment was carried out by comparing welfare-type chicken cages with traditional chicken cages.

[0020] One target animal was selected among 5 chickens in each replicate group and marked by smearing paint on the body of the chicken. During the experiment, observe its feather pecking and other behaviors. ...

Embodiment 3

[0030] In this example, Hailan white-feathered laying hens were selected as experimental animals. From 0 weeks old, 200 Hailan white feather hens were raised. The formal test started from the 6th week of age, randomly selected 120 laying hen chicks with uniform weight and strong body, and randomly divided them into 20 groups, with 6 chickens in each group. Among them, 10 groups were raised in the welfare-type chicken cages, and 10 groups were raised in traditional chicken cages. Using traditional chicken cages, only drinking water and feed are provided, without laying boxes, foot pads, pecking pads, perch bars, sand trays, and hanging strings. In the rearing period, a comparative experiment was carried out by comparing welfare-type chicken cages with traditional chicken cages.

[0031] The behavior observation method and statistical analysis of this embodiment are the same as those in Embodiment 2.

[0032] The experimental results are shown in Table 3, the results of compa...

Abstract

The invention discloses a chicken coop for improving a benefit level of laying hen. The chicken coop comprises a chicken coop body (1), wherein the chicken coop body (1) is divided into an egg laying area a and a rest area b by virtue of a door curtain (2), the egg laying area a is integrally of a square box body, a henroost crossbar (3) is horizontally arranged in the box body, two ends of the crossbar (3) are respectively fixed on two ends of the box body, the top of the rest area b is provided with a plurality of strings (4), a foot mat (6) and a sand bath tray (6) are paid on the bottom of the rest area b, and the left side and the middle part of the rest area b are respectively provided with a peck mat (7). By adopting the chicken coop, the nesting egg laying behavior of the laying hen under a natural condition can be normally performed. The breaking rate of the egg is reduced; the normal scratching behavior of the laying hen can be satisfied, and the off quality of the laying hen claws can be improved; the peck behavior of the laying hen can be satisfied, the feather pecking occurrence rate of the laying hen is reduced, and the skin and feather quality of the laying hen can be improved.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a chicken cage for improving the welfare level of laying hens. Background technique [0002] In the production of laying hens, due to the monotonous environment of the current chicken cages and the lack of natural environments such as laying nests, sand, and habitats under natural conditions, laying hens will lie on their nests, sand bath, scratch and normal habitats. Resting, pecking behavior is difficult to express, so the welfare level of layers in layer cages is very low. Therefore, it is particularly important to improve the welfare level of caged laying hens from the perspective of the cage environment. The improvement of the welfare level of laying hens can not only meet the welfare level of laying hens themselves, but also improve the production performance of laying hens, such as improving the quality of eggs and chicken. Contents of the invention [0003] The object o...
