Description

Technical Field

[0001] The invention relates to a method and a device for enhancing the spray immunization effect in a hatching hall. Background Art

[0002] Infectious bronchitis (IBD) is an acute, highly contagious respiratory disease that affects chickens of all ages. Effective vaccination is an important means of preventing and controlling the disease. Spray immunization is usually used in the hatchery to vaccinate one-day-old chicks to gain immunity.

[0003] It is generally believed that during spray immunization, chicks absorb the vaccine by inhaling vaccine liquid particles and spraying the vaccine liquid directly on the surface of mucous membranes (e.g., inside the eyes). However, studies have found that, especially for one-day-old chicks, the chicks mainly rely on pecking at vaccine droplets attached to feathers to obtain the vaccine. Therefore, encouraging chicks to peck at vaccine droplets attached to each other after spraying is an important / key factor in ensuring the immunization effect.

[0004] On the other hand, in continuous production, after the chicks have completed the spray immunization, the chick boxes are temporarily stored on the chick transport cart next to the spray equipment. Usually, two rows of chick boxes are stacked in turn on one cart (one row of boxes on the left and right of a chick transport cart, stacked in turn). When the chick transport cart is stacked to 8 layers of 16 boxes, it is transported to the chick storage room. In practice, the time interval between the stacking of the upper and lower layers of chick boxes on the cart is only 20 seconds, and then the lower layer of chick boxes is blocked by the upper layer. If the interval time is extended, it will seriously affect the production effect. Summary of the invention

[0005] The purpose of the invention is to promote the mutual pecking of vaccine droplets by chicks after spraying under the condition of ensuring the production efficiency, so as to ensure the reliability and effectiveness of vaccination against bronchiolitis and the like.

[0006] The technical solution of the present invention is: a method for enhancing the spray immunization effect in the hatchery. During the loading process of chick boxes after spraying, based on the lights in the loading area, the chicks are exposed to short-term strong light, which promotes the chicks to peck each other, thereby ensuring the vaccination effect.

[0007] Preferably, the chick boxes continuously delivered by the spray device are stacked layer by layer on the chick transport cart in sequence, and the chicks in the chick boxes are exposed to light from the loading area on the chick transport cart until the chick boxes on the upper layer are stacked on top of them. The time interval between stacking two adjacent layers of chick boxes is the time that the chicks receive short-term strong light exposure.

[0008] Typically, the chick boxes stacked on the top layer of the chick transport vehicle are covered with cardboard (or other similar coverings) before the chick transport vehicle is transported out. The time for the chick boxes on the top layer to receive short-term strong light is the time before they are covered with cardboard on the chick transport vehicle. This time is the same as or slightly longer than the time interval between the stacking of two adjacent layers of chick boxes based on the normal operating process.

[0009] According to the above-mentioned strong lighting method, the normal operation process and operation method of transporting chicks in boxes will not be affected.

[0010] Preferably, the time interval between stacking the chick boxes in adjacent layers is 20 seconds, and the light intensity in the loading area (light intensity when strong light is implemented) is 30-50 lux.

[0011] At the time interval between stacking chick boxes in any adjacent layers, the appropriate light intensity for the loading area can be obtained based on experiments. Generally, it should not be lower than the minimum light intensity that allows the chicks to reach a pecking rate of 95%-98% within 3 minutes, and should not be too high to avoid excessive / undue stress reactions in the chicks.

[0012] Furthermore, a strong light lamp (including a lamp specially provided for enhancing the light intensity, which may or may not include the original conventional lighting lamp) is provided which can provide the required light intensity (the light intensity of strong light) for the chicks in the chick boxes stacked on the chick transport vehicle. During the loading of the chick boxes, the strong light lamp is turned on to provide strong light exposure to the chicks in the chick boxes.

[0013] Preferably, during the spraying process, strong light is not applied to avoid excessive stress response caused by the superposition of spraying and strong light.

[0014] Preferably, strong light is not applied during the transportation of the chick transporter to avoid excessive stress response caused by the superposition of transportation and strong light.

[0015] A device for enhancing the spray immunization effect in an incubation hall comprises an incubation hall for implementing spraying, wherein the incubation hall is provided with a spray device and a loading area next to the spray device, wherein the incubation hall is provided with a strong light lamp capable of providing the required light intensity (strong light intensity) to chicks in chick boxes stacked on a chick transport vehicle, and during the loading process of the chick boxes after the spraying is completed, the strong light lamp is used to implement short-term strong light exposure to the chicks in the chick boxes to promote the chicks to peck each other, thereby ensuring the vaccination effect.

[0016] Preferably, the strong light is / includes an LED light strip arranged on the wall of the loading area.

[0017] Preferably, the strong light is / includes a light tube arranged on the roof above the loading area.

[0018] Furthermore, the spray device is provided with a conveyor belt, through which the chick boxes are sequentially sent into the spray area to be sprayed with the vaccine diluent. The chick transport vehicle is a manpower vehicle, which manually stacks the chick boxes according to the output rhythm of the spray device.

[0019] The beneficial effect of the present invention is that since lighting of appropriate intensity is provided in the loading area of ​​the chick transport vehicle, the mutual pecking rate of the chicks is effectively improved. According to a field comparative test, the light intensity (illuminance) is controlled at 35-40Lux, and the time interval between the stacking of the upper and lower layers of chick boxes is kept unchanged at 20 seconds. The mutual pecking rate of the chicks is increased from the original 82%-84% to 95%-98%, thereby improving and ensuring the vaccination effect.

[0020] The present invention does not change the operation mode, does not increase the workload and labor intensity, is easy to implement, has low cost and good effect, and can be used for the vaccination of chicks, especially one-day-old chicks, with infectious vaccines and other similar vaccines.

[0024] See also Figure 1 and Figure 2 The method of vaccinating one-day-old chicks with infectious bacillus vaccine is spraying. A certain number of chicks are placed in a chick box 2 and sent to a spray device 4 for spraying. The spray device is provided with a nozzle and a sensor that can automatically sense the absence of a chick box signal at the spray station. The chick box is sprayed according to the signal. After the spraying is completed, the conveyor belt 6 continues to move to send the chick box out. The sprayed chick boxes are manually stacked layer by layer on the chick transport cart 1. Usually, two chick boxes are placed side by side on each layer of the chick transport cart, and each cart is stacked up to 8 layers and 16 boxes. After stacking, cover the top chick box with cardboard (the chicks in the top chick box still need to be exposed to light for 20 seconds), and use a cart to transfer the chicks to the chick storage room.

[0025] When stacking, two rows of chick boxes are stacked in turn on one cart. The interval between the stacking time of the upper and lower layers of chick boxes on the cart can be controlled within 20 seconds, and then the chick boxes on the lower layer are blocked by the upper layer. Therefore, the effective light time for the chicks at this stage is only 20 seconds.

[0026] Experiments have shown that after the spraying is completed, the chick boxes can be temporarily stored on the chick transport cart for a short time, and the light intensity of the chicks can be appropriately increased, which can significantly increase the mutual pecking rate of the vaccine droplets. Experiments show that by increasing the light intensity in the chick parking (loading) area from more than ten lux under normal operating conditions to 35-40 Lux, while maintaining the lighting time of 20 seconds unchanged, the mutual pecking rate within 3 minutes can be increased from 82%-84% to 95%-98% (since the spray droplets can only last for 3 minutes on the chicks, it is only necessary to observe the mutual pecking rate within 3 minutes).

[0027] The experiment also found that increasing the light intensity in the loading (short stop) area after the chicks were sprayed was sufficient to obtain a sufficiently high rate of mutual pecking and achieve effective vaccination. It is not advisable to implement strong light before and during spraying to avoid excessive stress response in the chicks caused by the superposition of spray and strong light. Comparative experiments show that after increasing the light intensity after spraying, the overreaction caused by the superposition of strong light and spray not only has no substantial effect on promoting mutual pecking among chicks after spraying, but also damages the immunity of the chicks. For the same reason, excessive light intensity is also unnecessary or disadvantageous.

[0028] Any suitable method can be used to increase the light intensity in the loading area after spraying, and the light intensity can be controlled to be above 30Lux and not more than 40lux or 50lux (when the chicks are exposed to light for 20 seconds, that is, when the time interval between the upper and lower layers of chick boxes being stacked in place is 20 seconds).

[0029] Example 1. Install LED light strips 3 on the side walls of the area where the chicks temporarily stay after spraying (see Figure 1 ). The top of the light strip can be slightly higher than the top height of the 8-layer chick boxes normally stacked, and the bottom is slightly lower than the bottom of the chick boxes on the first layer, so that the light can effectively illuminate all the chick boxes. The length of the light strip on the wall is slightly larger than the length of the chick storage trolley. For example, there can usually be at least 8 rows of light strips, and each row is evenly distributed to facilitate uniform light intensity in the chicken box.

[0030] Embodiment 2. Install the lamp tube 7 on the roof (ceiling) (see Figure 2 ), increase the light intensity by increasing the power or number of lamps, and require that it can cover the range of two chick storage carts, so that the minimum light intensity for all chick boxes is not less than 35Lux.

[0031] The following are some comparative experimental results for the above two embodiments:

[0032]

[0033] The above experimental results show that if the stay time (effective illumination time) is maintained at 20 seconds, the pecking rate within 3 minutes is only 82-84% if the light intensity in the chicks' stay area is not increased (i.e., the original conditions on site are maintained). If the light intensity is increased to 35Lux, the pecking rate within 3 minutes can be increased to 95-98% regardless of whether the roof light tube or the wall LED light strip is used. In contrast, if the light intensity is kept unchanged at 10.5lux, the effective illumination time needs to be doubled (to 40 seconds) to increase the pecking rate within 3 minutes to 95-98%.

[0034] The spray device can adopt any suitable existing technology. For example, a conveyor belt can be provided to transport the chick boxes to the spray station (area), the nozzle corresponds to the spray area, and the automatic detection / sensing technology can be used to know that the chick boxes have arrived at the spray station, and the nozzle is turned on to spray. After the set spray time is reached, the spray is stopped, and the conveyor belt is started to send the chick boxes out. The chick boxes that have been sprayed are manually moved to the chick transport cart, and the upper chick boxes placed on the chick transport cart are open to receive light irradiation until the chick boxes at the corresponding position on the upper layer are placed on top of them to block the light. When stacking the chick boxes on the last layer, keep them open for 20 seconds, and then use the chick transport cart to transfer the chick boxes (chicks) to the chick storage room.

[0035] The present invention has the following characteristics:

[0036] 1) The spray light enhancement device in the hatchery is simple and easy to implement. It can effectively increase the pecking rate of chicks from the original 82%-84% to 95%-98%, ensuring the effectiveness of vaccination, which is beneficial to the prevention and control of infectious bronchitis and ensuring the production performance of the flock.

[0037] 2) The chick pecking rate is increased by increasing the light intensity without increasing the labor intensity or changing the working method, which is easy to promote and apply.

[0038] 3) This solution is simple in design, easy to install, low in cost, and the equipment is stable and has a long service life.

[0039] Unless otherwise specified or when one preferred or optional technical means is a further limitation of another technical means, the preferred and optional technical means disclosed in the present invention can be arbitrarily combined to form several different specific implementation methods.
