[0002] In the breeding methods of finishing pigs, pig houses are generally used for raising them, and reducing odor emissions in the pig houses is a necessary measure. Odor emissions can be reduced by suppressing the odor source and controlling the breeding process. The odor from finishing pig farming is generally produced by typical odorous substances such as ammonia, hydrogen sulfide, and phenols and indoles in the feces. How to reduce odor emissions has been a technical problem that has been studied in finishing pig farming for a long time. Specifically, depending on the feeding food or the degradation of odorous substances, different comparative testing methods are needed to determine which method is more effective. In particular, the odor from finishing pig farming is mainly produced by ammonia in the feces, and there is currently no convenient test model environment for comparative testing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example 1
[0016] Please see Figures 1-3An ammonia monitoring system includes a cage 1 for accommodating pigs, a feeding unit 2 connected to one end of the cage 1, and a collection trough 3 connected to the bottom of the cage 1. The bottom of the collection trough 3 is provided with a channel 31 communicating with the outside. An ammonia detection unit is provided on the side wall of the collection trough 3. The bottom of the cage 1 is provided with a grid plate 11 for allowing excrement to fall into the collection trough 3. The collection trough 3 is provided with a guide module and a cleaning unit 34. The cleaning unit 34 is used to clean the excrement in the collection trough 3 and guide the excrement to the channel 31 through the guide module, and discharge it to the outside of the collection trough 3 through the channel 31.
[0017] In practical applications, staff place pigs on cage 1 and feed them through feeding unit 2. When the pigs defecate, their excrement falls through the grid plate 11 into the collection trough 3, and is then discharged from the collection trough 3 by the cleaning unit 34. This allows staff to set experimental conditions according to actual circumstances. Specifically, the experiment uses fattening pigs as a model, analyzing growth performance, digestive tract absorption function, intestinal health, hindgut digesta, and ammonia emissions in feces. It aims to establish bioactive substances and technologies that improve the digestive and absorptive function of pigs and reduce odor pollutant emissions from the source of breeding. Furthermore, it employs metagenomics, metagenomics, and other multi-omics technologies to elucidate the specific mechanisms by which bioactive substances reduce odor production. Specifically, the experiment sets up different feeds to be fed within the same time period, measures the ammonia concentration produced by excrement within the same time period, and compares the results. By comprehensively comparing feeding costs, one or two functional compound packs with better effects are selected.
[0018] Preferably, the guiding module is a guide block 33, which has a right-angled trapezoidal structure. When the excrement falls from the grid plate 11, the top of the guide block 33 is used to support the excrement. The cleaning unit 34 is used to discharge the excrement from the top of the guide block 33 through the inclined surface of the side of the guide block 33 to the through groove 31, and then discharge it to the outside of the collection tank 3 through the through groove 31.
[0019] With the above design, the excrement of fattening pigs falls onto the top of guide block 33 and accumulates there, which is inside collection tank 3. Therefore, the excrement will not be discharged outside collection tank 3 before cleaning by cleaning unit 34. Thus, in a single experiment, the loss of excrement will not cause deviation in the measured ammonia concentration, thereby affecting the accuracy of the experimental results. After a single experiment, the final ammonia concentration reading is recorded, cleaning unit 34 is activated to discharge the excrement from collection tank 3, the ammonia detection unit is reset, and the next round of experimental testing begins. This is beneficial because the next experiment will not be affected by the previous experiment, thus improving the accuracy of the comparative data of different experimental groups.
[0020] More preferably, the cleaning unit 34 includes a plurality of nozzles 341, which are located on the side wall of the collection tank 3 and are arranged in the direction of water spray towards the top of the guide block 33. The plurality of nozzles 341 are used to discharge excrement from the top of the guide block 33 through the inclined surface of the side of the guide block 33 to the through channel 31, and then discharge it out of the collection tank 3 through the through channel 31.
[0021] In this embodiment, multiple nozzles 341 can spray water toward the top of the guide block 33, thereby spraying the excrement located on the top of the guide block 33 toward the inclined surface on the side of the guide block 33, and then discharging it from the through groove 31 to the outside of the collection tank 3 through the inclined surface. In this way, the excrement located on the top of the guide block 33 can be completely washed away and carried by the water flow to the through groove 31 for discharge, thereby improving the cleaning efficiency and cleaning effect.
[0022] More preferably, the ammonia detection unit includes a plurality of ammonia detectors 32, and at least one ammonia detector 32 is provided on each side wall of the collection tank 3, with the plurality of ammonia detectors 32 located in the upper half of the side wall of the collection tank 3.
[0023] In the above design, since the density of ammonia is lower than that of open space, it will float upward when ammonia is generated from excrement. Therefore, it is beneficial to set the ammonia detector 32 on the upper half of the side wall of the collection tank 3 to detect the ammonia concentration. Having an ammonia detector 32 on each side wall can detect the ammonia concentration more completely, and the readings of multiple ammonia detectors 32 can be compared, such as the maximum value, total value, and average value of ammonia concentration, which improves the flexibility of the experiment.
[0024] More preferably, a baffle 12 is provided at the end of the cage 1 away from the feeding unit 2, and the baffle 12 is designed to be rotatable.
[0025] With the above design, when the pig does not defecate downwards, it will defecate horizontally. At this time, the baffle 12 can block the excrement from being discharged outwards and will move towards the bottom of the cage 1, eventually falling through the grid plate 11 to the top of the guide block 33. This avoids the accuracy of the experimental results being affected by the reduction in the amount of excrement. On the other hand, the baffle 12 can be rotated and opened to facilitate the staff to drive the pig to the cage 1 for the experiment, and also to facilitate the pig to be driven out of the cage 1 after the experiment.
[0026] The top of the baffle 12 is provided with a plurality of water spray pipes 121 arranged with the water spray direction facing downward.
[0027] In this embodiment, the water spray pipe 121 can clean the baffle 12 and the grid plate 11, which helps to prevent two adjacent experiments from affecting each other and thus affecting the accuracy of the experimental results.
[0028] Furthermore, it also includes a collection frame 4. The collection tank 3 includes a test area 35 and a collection area 36. The collection area 36 is located below the test area 35. The collection frame 4 is movably connected in the collection area 36. The collection frame 4 is connected to the through channel 31. The collection frame 4 is used to collect excrement and sewage discharged from the through channel 31.
[0029] In this embodiment, the collection frame 4 can collect the excrement and sewage sprayed by the nozzle 341 on the guide block 33, as well as the sewage cleaned by the spray pipe 121, so that the staff can handle the excrement and sewage together, improve the utilization rate of resources, and the collection frame 4 can ensure that the excrement and sewage falling from the channel 31 are collected to avoid environmental pollution.
[0030] Preferably, one end of the collection frame 4 is provided with a handle 41, and the bottom of the collection frame 4 is provided with a roller 42.
[0031] The above design makes it easy for staff to pull the collection box 4 out of the collection area 36 for processing; it also makes it easy for staff to put the collection box 4 into the collection area 36 to collect excrement and sewage.
[0032] More preferably, the feeding unit 2 includes a feeding trough 21, a storage trough 22, and a partition 23. The storage trough 22 is connected to one end of the cage body 1, the feeding trough 21 is connected below the storage trough 22, and the partition 23 is located between the feeding trough 21 and the storage trough 22. The partition 23 can rotate around one side of the bottom of the storage trough 22 to separate the storage trough 22 and the feeding trough 21 or to connect the storage trough 22 and the feeding trough 21.
[0033] In this embodiment, the staff can place the feed in the storage tank 22 and block it with the partition 23. When feeding is needed, the staff can rotate the partition 23 to drop the feed in the storage tank 22 into the feeding tank 21 for feeding. This method can facilitate the staff to feed the feed at regular times and in fixed quantities.
[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
