Description

Technical Field

[0001] The present application relates to the technical field of poultry production and breeding, and in particular to a poultry welfare breeding house and a method for tracking hatching egg information thereof. Background Art

[0002] With the development of animal welfare concepts and science over the past 50 years, a series of animal welfare implementation and evaluation systems have been developed. The production efficiency and product quality of farm animals have also gradually improved, giving more and more countries the confidence to abandon cage production methods.

[0003] For a long time, the Chinese people have favored free-range eggs, and naturally many local chicken breeds with their own characteristics have been formed. The best way to preserve and breed them is to maintain the existing free-range model. However, under the free-range model, it is not convenient to record and trace individual egg production. Free-range chickens also tend to lay eggs in groups. The existing egg-laying nests cannot distinguish which hen the eggs come from, and further detailed tracking is needed. The time of their production is also unknown. There is an urgent need to develop a means to accurately and effectively track egg information while maintaining the welfare of poultry in a free-range state. Summary of the Invention

[0004] The main purpose of this application is to provide a poultry welfare breeding house, aiming to solve the problem in the existing technology that it is impossible to track hatching egg information in the free-range mode.

[0005] The technical solutions adopted in this application are as follows:

[0006] A poultry welfare breeding house, comprising a quadrangular chicken house, a balcony and a grazing area; wherein:

[0007] The chicken house is divided into several triangular compartments by protective nets;

[0008] The balcony is set outside the two long sides of the chicken house. The outside of the balcony is surrounded by a fence wall to form a grazing area. The grazing area is divided by the fence wall into multiple independent grazing areas corresponding to each triangular compartment;

[0009] Each triangular compartment has an egg-laying nest in the corner, equipped with a pedal and an egg box. The pedal can track the information of the hens that come to lay eggs, and the egg box can collect the eggs in the order of laying. A combined perch is set in the center of each triangular compartment. On one side of each triangular compartment, parallel to the long side of the chicken house, there is a balcony door for entering and exiting the balcony.

[0010] On the balcony, there are water dispensers and feeders on both sides of each balcony door.

[0011] Optionally, the direction in which the long side of the chicken house extends is consistent with the prevailing wind direction at the geographical location where the chicken house is located.

[0012] Optionally, lighting is provided in the triangular compartment and above the balcony door, and the lighting is controlled by an automatic time-delay switch.

[0013] Optionally, a plurality of evenly spaced slits are provided on the bottom plate of the balcony, and the width of each slit is 15-20 mm.

[0014] Optionally, the pedals are provided with an identification device and a weight sensing device, the identification device is used to identify the identity information of the hen coming to lay eggs, and the weight sensing device is used to sense the weight information of the hen coming to lay eggs.

[0015] Optionally, the balcony door is a sliding door or a hanging door.

[0016] Optionally, the chicken house is set up off the ground with a height of not less than 60 cm from the ground.

[0017] Optionally, each laying nest includes 1-2 independent laying nests, each laying nest is provided with a red or yellow front curtain, the middle of the curtain is empty and forked, and the inner concave width of the laying nest is 25-35 cm, the depth is 45-50 cm, and the height is 40-45 cm.

[0018] Optionally, the identification device is a smart anklet identifier, and the weight sensing device is an electronic scale.

[0019] In addition, to achieve the above purpose, the present application also provides a method for tracking hatching egg information, comprising the following steps:

[0020] When each chick is born, it is given a unique wing number carrying the information of its parents. The chicks are mixed and fed. Before grouping to breed the next generation, a family is formed based on the performance indicators of existing breeders and the principle of avoiding inbreeding. Each triangular compartment is used to raise a family of breeders. Each family includes a rooster and 10-15 hens. They are then fitted with electronic leg rings with their individual numbers written into them. They are then transferred to the poultry welfare breeding house provided by this application.

[0021] When a domestic hen enters the nest through the pedal, the identification device identifies the hen's information. At the same time, the weight sensor identifies and records the time the hen entered the nest and the weight information at that time and stores it on the chip of the electronic leg ring.

[0022] The eggs produced by the brooding hens are collected through the egg box, and the weight sensor device identifies and records the time when the brooding hens leave the nest and the weight information at that time;

[0023] Determine the egg weight, and determine the laying hen information based on the recorded information of the electronic leg ring, and determine the weight of the laid eggs based on the weight difference of the hen before and after laying eggs;

[0024] Based on the information of laying hens and egg weight, pedigree incubation and breed selection are carried out. After the family has enough breeding stock, the protective net can be partially removed as needed and the triangular compartments in the chicken house can be merged.

[0040] Refer to the attached Figure 1-2 The first embodiment of the present application provides a poultry welfare breeding house, comprising a quadrilateral chicken house 13, a balcony 12 and a grazing area; wherein:

[0041] The chicken house 13 is divided into a plurality of triangular compartments 131 by a protective net to ensure that chickens of different families are not mixed up in the future;

[0042] The balcony 12 is arranged outside the two long sides of the chicken house 13. The outside of the balcony 12 is surrounded by a fence wall or a partition net 10 to form a grazing area. The grazing area is divided by the fence wall 10 into a plurality of independent grazing areas 11 corresponding to each triangular compartment 131.

[0043] An egg-laying nest 1313 is provided at a corner of each triangular compartment 131. The egg-laying nest 1313 is provided with a pedal and an egg box. The pedal can track the information of the hens that come to lay eggs. The egg box can collect the eggs in the order of laying eggs. The eggs produced in real time can be collected and recorded in a timely manner by manual labor, or the egg box design provided in this application can be used. A combined perch 1312 is provided at the center of each triangular compartment 131. A balcony door 1311 for entering and exiting the balcony 12 is provided on one side of each triangular compartment 131 parallel to the long side of the chicken house 13.

[0044] On the balcony 12, and on both sides of each balcony door 1311, a drinking fountain 122 and a feeding fountain 121 are respectively provided.

[0045] In this embodiment, the chicken house 13 is divided into different families by setting up a protective net, and an independent free-range and grazing space is provided for each family, and an independent feeder 121 and waterer 122 are provided for each family. The combined perch 1312 in the triangular compartment 131 can increase the richness of the environment. The identity of the chickens coming to lay eggs is identified by using an identification device and a weight sensing device, and the weight and time of entering and leaving the nest are recorded. In conjunction with the breeding eggs collected in order in the egg box, the breed preservation and selection are achieved under the premise of taking into account the welfare of the poultry, and the time when each breeding egg is produced and the information of the laying hen can be accurately tracked.

[0046] In one embodiment, the long side extension direction of the chicken coop 13 is set to be consistent with the mainstream wind direction of its geographical location to prevent the cold wind from entering the coop in winter. The fence wall 10 can be made of bamboo strips or a combination of trees and flowers, which can prevent epidemics and be beautiful. In order to avoid the trouble of setting up, an isolation net can be used to replace the fence wall 10, so that it is convenient to erect, repair and replace.

[0047] Furthermore, in order to meet the lighting requirements of the laying hens in the chicken house 13, lighting lamps are installed in the triangular compartment 131 and above the balcony door 1311. The lighting lamps are controlled by automatic delay switches to ensure that 20 lux of illumination is provided for 16 hours a day (including daylight time).

[0048] Furthermore, because the balcony 12 has sufficient light, the feeder 121 and the waterer 122 can be set on the balcony 12 to provide a good environment for feeding and reduce the amount of feces in the chicken house 13. To ensure the cleanliness of the balcony 12, a plurality of evenly distributed gaps are provided on the bottom plate of the balcony 12. The width of each gap is 15-20 mm. When feeding, there is a lot of feces, which can fall through the gaps. After the above settings, in order to facilitate ventilation and hygiene of the chicken house 13 and to cooperate with the falling of chicken manure on the balcony 12, the chicken house 13 can be raised as a whole and set off the ground. The height from the ground depends on the terrain and is generally not less than 60 cm.

[0049] Furthermore, in order to ensure that the chickens have enough food to eat and there will be no food snatching due to insufficient troughs, the feeder 121 and the waterer 122 provide bilateral feeding trough positions to ensure that each chicken has a 5 cm feeding position and a 2.5 cm drinking position, or each group has a nipple drinker with two drinking heads.

[0050] Furthermore, the balcony door 1311 is a sliding door or a hanging door, with the principle of not affecting the chickens' entry and exit and facilitating feeding. On rainy days or low temperature days when grazing is impossible, the door from the balcony to the grazing area can be closed to ensure the health of the chickens. A canopy can also be installed on the balcony 1311 to ensure that the chickens are not wet when feeding on rainy days.

[0051] In one embodiment, the pedals are provided with an identification device and a weight sensing device. The identification device is used to identify the identity information of the hens coming to lay eggs. The identification device can adopt the smart foot ring identifier provided in the embodiment of the present application, or a camera capable of capturing and identifying. The weight sensing device is used to sense the weight information of the hens coming to lay eggs. The weight sensing device can be a pressure sensor, an electronic scale, an electronic meter, etc. that can realize mass sensing detection. The weight difference between the hen entering the nest and leaving the nest is the weight of the eggs laid. The electronic scale with a built-in display is preferred, which can record data in real time. When manually picking eggs, it can assist in determining the production time and source of the breeding eggs, provide an important reference for breeding egg marking, and lay the foundation for subsequent pedigree incubation and variety breeding.

[0052] In one embodiment, the structure of the combined perch 1312 is optimized, as shown in the attached Figure 2As shown, in order to increase the richness of the environment and provide a diverse activity environment for the chickens, specifically, the combined perch 1312 is in the shape of a triangular cone as a whole and consists of three poles 13121. A horizontal triangular perch 13123 is set at two-thirds of the height from the ground, and a round platform 13122 is set at one-third of the height from the ground. A hanging line 13124 is set on the edge of the round platform 13122 to connect it to the triangular perch 13123 above. The edge of the round platform 13122 does not contact the poles. When there are chickens moving on the round platform 13122, the round platform 13122 can swing to a certain extent, which is beneficial to increase the leg strength of the chickens. The round platform 13122 can minimize the collision with the chickens during exercise, will not hinder the chickens' activities, and can also be used as a step to fly to a higher perch. When the chickens want to rest quietly, they can fly to the fixed triangular perch 13123 above through the round platform 13122.

[0053] Furthermore, the circular platform adopts a slit design with multiple evenly distributed mesh holes with a diameter of 20-25 mm, which facilitates the leakage of chicken manure and keeps the circular platform clean. When the triangular perch is not enough, the number of layers of perches can be increased above the circular platform.

[0054] Furthermore, in order to increase the comfort of the chicken claws when grasping the tripod perch, the cross-bar cross-section of the tripod perch is preferably a semicircular wooden stick with a diameter of 5-7 cm and an anti-slip pattern on the surface of the wooden stick.

[0055] In one embodiment, the structure of the egg-laying nest 1313 is optimized, specifically as follows: the egg-laying nest 1313 includes 1-2 independent egg-laying nests, each of which has an inner concave width of 25-35 cm, a depth of 45-50 cm, and a height of 40-45 cm. The size can only accommodate a single hen to lay eggs, avoiding aggregate egg-laying and ensuring that the hens must pass through the pedal when coming to lay eggs, thereby facilitating individual egg-laying tracking.

[0056] In one embodiment, in order to facilitate the automatic collection of eggs, the structure of the egg-laying nest 1313 is optimized. Specifically, the egg-laying nest 1313 adopts a double-layer design, and the bottom plate of the upper layer is tilted backward by 5-15 degrees. Straw is laid as the egg-laying nest 1313. A gap is opened at the bottom end of the tilted bottom plate to allow the eggs to leak out. After the eggs are laid, they are guided by the tilted bottom plate to fall into the lower layer through the gap. The bottom plate of the lower layer is tilted forward by 5-15 degrees, and gradually shrinks to an opening of 5 cm through an arc-shaped transition section, and then connected to the front end of the egg box. The order in which the eggs are arranged in the egg box is the order in which the eggs are laid.

[0057] Furthermore, the bottom of the egg box is hollowed out to facilitate the leakage of possible accompanying feces. The egg box is connected to the lower opening of the egg-laying nest 1313, which makes it easy to remove the eggs from the egg box and pick up the eggs. A soft arc-shaped egg trough with a width of 5 cm is provided in the egg box to connect with the egg-laying nest 1313 to ensure that eggs produced in the same nest will not be stuck at the exit, ensuring that each egg produced will be collected in turn, and no eggs will be left in the egg-laying nest 1313, reducing the chance of eggs being incubated or contaminated by hens, and also reducing the time hens stay in the egg-laying nest.

[0058] In one embodiment, in order to disperse the laying hens as much as possible, avoid crowding and overlapping to lay eggs and cause interference to each other, and facilitate tracking of individual information, the egg-laying nest 1313 is provided with a front curtain, which covers the egg-laying nest 1313 in the corner of the triangular compartment 131. The front curtain is set to red or yellow, the color preferred by the hens, so that the chickens can feel safe. A triangular empty part is set in the middle of the front curtain to facilitate the hens to check from inside the nest.

[0059] Furthermore, if the light is strong, in order to create a darker environment for the hens to lay eggs, a top cover is provided for the egg-laying nest 1313. However, in order to prevent the hens from staying on the top cover and leaving feces, the top cover can be provided with a steep slope.

[0060] A second embodiment of the present application provides a method for tracking hatching egg information, comprising the following steps:

[0061] When each chick is born, it is given an electronic leg ring with its individual number written into it. The electronic leg ring also carries the unique wing number of its parents' information.

[0062] In each triangular compartment 131 of the poultry welfare breeding house provided by the present application, chicks are mixed-fed. Before grouping and breeding the next generation, families are formed based on the performance indicators of existing breeder chickens and the principle of avoiding inbreeding. Each triangular compartment 131 houses a family of breeder chickens, each of which includes a rooster and 10-15 hens. The length of the chicken house 13 is determined according to the terrain and the number of chickens in the flock. Each triangular compartment 131 occupies 3-4 square meters, and each family includes a rooster and 10-15 hens.

[0063] Feed the chicks normally and graze them appropriately. On rainy or cold days, the door from the balcony to the grazing area can be closed. By opening the balcony doors 1311 in different directions, outdoor rotational grazing can be achieved, allowing the grazing area to be grazed in a cycle.

[0064] When a hen enters the egg-laying nest 1313 through the pedal, the identification device identifies the information of the hen coming to lay eggs. At the same time, the weight sensing device identifies and records the time when the hen enters the egg-laying nest 1313 and the weight information at that time and stores it in the chip of the electronic anklet;

[0065] The eggs are collected through the egg box, and the weight sensor device identifies and records the time when the hen leaves the nest and the weight information at that time;

[0066] Determine the egg weight, and determine the laying hen information based on the recorded information of the electronic leg ring, and determine the weight of the laid eggs based on the weight difference of the hen before and after laying eggs;

[0067] Based on the laying hen information and egg weight information, pedigree incubation and breed selection are carried out. After the number of breeders left in the family is sufficient, the protective net is removed and the triangular compartments 131 in the chicken house 13 are merged.

[0068] In this embodiment, the electronic scale and smart anklet identifier on the pedal can perform individual weighing and store the weight data for a short period of time (more than 24 hours) on the built-in chip, and can send the data to the host for long-term storage at regular intervals every day. The difference between two consecutive weights of the same chicken is the egg weight.

[0069] Taking into account that hens may sometimes defecate after entering the egg-laying box, or may lay double-yolk eggs, this can be corrected by manually collecting eggs or recording the egg weight in the past few days. Because the hens' choice of egg-laying nests 1313, egg weight and egg shape are individually stable, and egg weight tends to increase slowly with age, the eggs produced by each breeding hen can be accurately determined through the hen's electronic leg ring to accumulate breeding data.

[0070] Through the display screen on the electronic scale, when manually picking up eggs, you can check the time when the hen enters and leaves the nest 1313. Corresponding to the order of egg production, the production time and source of the eggs can be determined. This is an important reference when manually collecting eggs for marking. Moreover, when the hen touches the pedal, the sensor can also record the weight change of the hen entering and leaving the nest. The weight of the eggs can be determined by subtracting the weight before and after. These data are also an important basis for subsequent pedigree incubation and variety selection.

[0071] In one embodiment, considering that the time a hen stays on the pedal may be short, it is impossible to ensure that each sensing and identification is very accurate. The sensing and identification device is directly placed in the egg-laying nest 1313 where the laying hen must stay to lay eggs. Specifically, the egg-laying nest 1313 is provided with an identity recognition device and a weight sensing device. The identity information and weight information of the hen are recorded when the hen lays eggs. After the hen lays eggs, the eggs roll out through the inclined egg-laying nest 1313 and are collected in an egg box. At this time, the egg weight can be determined based on the difference between the recorded hen weight and the hen weight when entering the egg-laying nest 1313, and the identity of the laying hen can be determined based on the identity information. The egg box collects the eggs in order to ensure that the eggs can be matched with the recorded information after manual collection. In order to prevent the weight sensing device from working for a long time, it can be set to have a standby function. When a hen comes, the weight sensing device detects a data change and records the data every five minutes. After the hen leaves, the weight sensing device detects that the weight data has decreased and has not changed for more than 20 minutes, and then enters the standby state to reduce work consumption.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
