Description

Technical Field

[0001] This application relates to the field of animal husbandry, and in particular to a modular non-human primate husbandry cage. Background Technology

[0002] Non-human primates, especially monkeys, are indispensable advanced experimental models for biomedical and psychological research. They are naturally active, highly intelligent, and possess a strong exploratory drive, social nature, and tendency towards stereotyped behaviors. Given their unique biological and behavioral characteristics, the quality of their captive environment directly impacts animal welfare, behavioral performance, and the reliability of experimental data. Therefore, it is necessary to provide a more suitable captive environment that is tailored to the animals' characteristics and living needs, while also facilitating management by zookeepers.

[0003] Currently, most primate enclosures are made of welded, fixed stainless steel. Their design fails to adequately meet the survival habits and behavioral needs of primates, resulting in significant deficiencies in animal welfare, operational safety, and husbandry efficiency. Firstly, monkeys are typical climbers, relying on heights for observation or climbing for survival in the wild. Traditional stainless steel enclosures are mostly simple cage structures, lacking three-dimensional climbing structures and vertical space. This restricts animal movement, easily leading to stereotyped behaviors, anxiety, and depression, severely impacting their mental health and the stability of experimental data. Furthermore, the monotonous cage environment fails to simulate natural habitats and cannot meet the monkeys' instinctive behavioral needs.

[0004] In view of the aforementioned technologies, the inventors believe there is a need to provide a breeding cage that can make the husbandry and management of non-human primates more scientific. Summary of the Invention

[0005] In order to improve the husbandry and management of non-human primates, this application provides a modular non-human primate husbandry cage.

[0006] The technical solution for a modular non-human primate rearing cage provided in this application is as follows: A modular non-human primate enclosure includes a cage frame, a resource supply system, a hygiene and cleaning system, an activity and enrichment system, and a connection and management system. The cage frame includes a cage base, a cage top, and cage side frames. The resource supply system includes a food supply device and a water supply device detachably installed on the cage frame. The connection and enrichment system includes a connection channel opened on the cage side frames and a connection cage door movably installed on the cage side frames for changing the opening and closing state of the connection channel. The activity and enrichment system includes a lookout component installed on the cage side frames, a climbing component located between the lookout component and the cage base, and multiple monitoring units installed on the cage top frame.

[0007] By adopting the above technical solutions, the modular rearing cage, comprising a cage frame, resource supply system, hygiene and cleaning system, activity and enrichment system, and connection and management system, provides rearing space and various services for non-human primates. The food and water supply devices of the resource supply system are detachable for easy replacement and maintenance. The connection management system's connecting channels and cage doors allow for changing the opening and closing of these channels, facilitating communication between different rearing cages and making animal management and relocation more convenient. The activity and enrichment system's observation components, climbing components, and monitoring units meet and monitor the animals' activity needs. This modular design not only facilitates production, transportation, and rapid on-site assembly but also allows for flexible configuration adjustments based on actual rearing needs, improving the cage's versatility and ease of maintenance, thereby enhancing the effectiveness of animal husbandry and management.

[0008] Optionally, the cage side frame includes a support frame and a plurality of support crossbeams connected between the support frames; the lookout assembly includes a lookout platform detachably mounted on the support crossbeams, a lookout frame mounted on the top of the lookout platform, and a lifting drive for driving the lookout frame to rise and fall relative to the lookout platform; the lookout frame is arranged with a plurality of lookout crossbeams for animals to grip.

[0009] By adopting the above technical solution, the cage side frame, composed of the support uprights and support crossbars, provides stable support for the rearing cage. The observation platform installed on the support crossbars is easy to install and disassemble, and its installation position can be adjusted according to the actual height of the cage side frame. The lifting drive mechanism drives the observation frame to rise and fall relative to the observation platform, allowing for flexible adjustment of the observation point's height and position based on the animal's body size, habits, and observation needs. Multiple observation crossbars spaced apart on the observation frame provide gripping points for the animals, meeting their activity and observation needs, and providing biomimetic gripping points to reduce the probability of falls. The observation components satisfy the innate instinct of non-human primates to climb and observe, helping to reduce their stereotypical behaviors, promote psychological well-being, and thus improve the husbandry and management of non-human primates.

[0010] Optionally, the climbing assembly includes a climbing ladder mounted obliquely on the top of the cage base frame, a climbing platform connected to the top of the climbing ladder frame, and a jumping platform arranged above the climbing platform; the jumping platform is provided with at least one and is detachably mounted on the inner wall of the cage side frame; the climbing platform has a visual barrier on the side facing the observation assembly.

[0011] By adopting the above technical solutions, climbing ladders, climbing platforms, and jumping platforms provide climbing and jumping spaces for non-human primates, simulating the natural environment, meeting the animals' exercise needs, and promoting physical health and muscle development. The detachable installation of the jumping platforms facilitates adjustment of the installation position or maintenance and replacement as needed. Visual barriers create relatively secluded areas for animals, reducing external disturbances during rest or activity, providing a relatively private space, reducing stress responses, alleviating tension, and improving animal welfare.

[0012] Optionally, the observation platform slopes downwards towards the inside of the cage from one side of the cage side frame; both the climbing platform and the jumping platform have multiple drainage holes; the cage base frame includes a cage base plate that is high in the middle and low around the edges; the sanitation system includes a drainage trough plate installed on the side of the cage base plate, a drainage pipe connected to the bottom of the drainage trough plate, and a liquid outlet installed on the cage side frame; the drainage trough plate has multiple drainage holes spaced apart; the bottom of the drainage trough plate is lower than the edge of the cage base plate and the side is not lower than the top surface of the cage base plate.

[0013] By adopting the above technical solution, the observation platform slopes downwards from one side of the cage frame towards the inside of the cage, allowing animal excrement to slide inwards along the top of the platform for easy collection and washing. The climbing and jumping platforms are equipped with drainage holes, which, combined with the cage floor plate's higher center and lower perimeter, allow excrement and other waste to flow smoothly through these holes and then down to the drainage trough via the sloping cage floor plate. The bottom of the drainage trough plate is lower than the edge of the cage floor plate, and its sides are not lower than the top surface of the cage floor plate, effectively collecting excrement. The drainage holes on the drainage trough plate and the connected drainage pipes facilitate the discharge of collected waste, while the outlet head discharges cleaning fluid to clean the cage, simplifying daily cleaning work, keeping the cage dry and hygienic, and reducing the probability of disease in the animals.

[0014] Optionally, the hygienic cleaning system further includes at least one liquid outlet pipe installed on the side frame of the cage; the liquid outlet pipe is sequentially connected to the liquid outlet head to provide cleaning fluid to the liquid outlet head; the liquid outlet pipe includes a liquid outlet section arranged horizontally relative to the bottom frame of the cage and a connecting section connected to the liquid outlet section; the end of the connecting section extends out of the cage frame and is provided with a liquid inlet; each liquid outlet head has a liquid outlet at its end for liquid to be sprayed out.

[0015] By adopting the above technical solution, the liquid outlet pipe is installed on the side frame of the cage and connected to the liquid outlet head in sequence, which can provide cleaning fluid to the liquid outlet head. The liquid outlet section of the liquid outlet pipe is arranged horizontally, and the end of the connecting section extends out of the cage frame to provide a liquid inlet for easy introduction of cleaning fluid. The liquid outlet at the end of the liquid outlet head allows the cleaning fluid to flow out at a suitable angle, forming a concentrated water column and atomization zone, which improves the cleaning efficiency, better cleans the rearing cage, and maintains the hygiene and cleanliness of the rearing cage.

[0016] Optionally, the food supply device includes a food supply box and a food box mounting plate for detachable installation of the food supply box; the food supply box has a feeding port, a feeding port for feeding animals, and a cleaning port at the bottom; there are multiple feeding ports of varying sizes; the inner wall of the food supply box at the feeding port is provided with a flexible baffle to prevent food from falling; the edges of each feeding port are designed to be rounded.

[0017] By adopting the above technical solution, the food feeder can be detachably installed on the feeder mounting plate for easy disassembly and maintenance. Multiple feeding openings of varying sizes simulate the challenge of natural foraging, extending feeding time and increasing behavioral richness. Flexible baffles reduce the probability of animals scooping out large amounts of food during feeding, thus minimizing waste, without hindering normal eating. Rounded edges on the feeding openings reduce the likelihood of animals being scratched while eagerly eating, improving safety. A cleaning opening at the bottom facilitates thorough removal of residue, helping to maintain the cleanliness and hygiene of the food feeder.

[0018] Optionally, the water supply device includes a water storage tank, a water circulation component connected to the water storage tank, and a water tank mounting plate for detachable installation of the water storage tank; the water storage tank has multiple drinking nozzles along its length on one side facing the cage frame; each drinking nozzle includes an elastic body and a water outlet slit opened at the end of the elastic body; the water outlet slit is normally closed under the action of the elastic body; the elastic body can open the water outlet slit when compressed and deformed.

[0019] By adopting the above technical solutions, the water storage tank, water supply circulation component, and water tank mounting plate ensure water supply. The water supply circulation component helps maintain the cleanliness and safety of the drinking water in the storage tank, and the detachable connection of the storage tank facilitates maintenance and replacement. Multiple drinking nozzles arranged along the length of the storage tank can meet the drinking needs of multiple animals simultaneously, reducing the probability of fighting among animals for water. The design of the elastic body and water outlet ensures the water outlet is normally closed, reducing drinking water waste and pollution. The water outlet only opens when animals squeeze the elastic body, improving the management level of drinking water hygiene.

[0020] Optionally, at least one mounting slide rail is installed on the lower side of the cage top frame; each mounting slide rail is equipped with at least one sliding trolley that can slide along its length; sliding guide grooves are symmetrically arranged on both sides of the mounting slide rail along the length; the sliding trolley is provided with sliding rollers that are rolled in the sliding guide grooves; the mounting slide rail is provided with a linear drive structure for driving the sliding trolley to slide; a universal interface is provided below the sliding trolley; the monitoring unit can be connected to the universal interface.

[0021] By adopting the above technical solution, at least one mounting rail is installed on the underside of the cage's top frame. A sliding trolley that can slide along the mounting rail is assembled. Utilizing sliding guide grooves and sliding rollers, the sliding trolley can slide smoothly. A linear drive structure drives the sliding trolley to slide, facilitating adjustment of the trolley's position while minimizing human interference with the animals' lives. The monitoring unit can connect to a universal interface for flexible monitoring of the conditions inside the cage, facilitating the observation and management of animal behavior.

[0022] Optionally, the active enrichment system further includes an olfactory enrichment device; the olfactory enrichment device includes an odor box connected to the universal interface and a timing mechanism connected to the odor box; each odor box includes a venting box and a venting cover movably mounted on the venting box; an air storage cavity is formed between the venting box and the venting cover; the venting box has a venting hole on its wall facing the venting cover; the timing mechanism drives the venting cover to open and close at set times to automatically release the odor material in the box at a set time.

[0023] By adopting the above technical solution, the activity enrichment system adds an olfactory enrichment device. The odor box of the olfactory enrichment device can be driven by a timer mechanism to open and close the vent cover at set times, and can automatically release the odor material in the box at set times, providing olfactory stimulation for the non-human primates, enriching their life experience, and meeting the natural behavioral needs of the animals.

[0024] Optionally, the cage frame is provided with a sliding door track at the bottom of the connecting channel; the bottom of the connecting cage door is provided with a sliding door groove that cooperates with the sliding door track; the connecting cage door includes a cage door body and a cage door drive component connected to the cage door body and driving the cage door body to move along the sliding door track.

[0025] By adopting the above technical solutions, the combination of the connecting channel and the sliding connecting cage door enables safer and more convenient transfer of animals or movement of animals between adjacent cages, greatly improving the efficiency and safety of husbandry and management, and effectively reducing the stress risk of animals during the transfer process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: A modular non-human primate rearing cage is designed by systematically breaking down the cage into different functional modules, including a cage frame, a resource supply system, a hygiene and cleaning system, an activity and enrichment system, and a connection and management system. This allows for the selection and adjustment of each module according to the specific needs of the animals. The food and water supply devices in the resource supply system are detachable for easy replacement and maintenance. The connection and management system allows for easy access between different cages by changing the opening and closing status of the access channels. The activity and enrichment system includes observation components, climbing components, and monitoring units to meet and monitor the animals' activity needs. This modular design not only facilitates production, transportation, and personalized assembly but also allows for flexible configuration adjustments based on actual rearing requirements, thereby improving the effectiveness of animal husbandry and management. By incorporating height-adjustable observation modules, multi-level climbing structures, and olfactory enrichment devices that provide olfactory stimulation, a three-dimensional, rich, and more natural animal activity environment can be constructed. The observation and climbing modules meet the animals' needs for climbing and exploration, the visual barrier provides a sense of security, and the timed release of odor stimuli enriches the sensory experience and alleviates animal anxiety. This effectively reduces stereotypical behaviors and stress responses in captive animals, promotes their physical and mental health, improves animal welfare, enhances the effectiveness of animal husbandry and management, and contributes to the reliability of the final experimental data. By setting up an inclined observation platform, a cage bottom plate that is high in the middle and low on all four sides, climbing and jumping platforms with drainage holes, and a drainage trough with drainage holes, combined with a liquid outlet that can be used for directional flushing, the waste can be washed, cleaned and collected, simplifying the cleaning process, keeping the cage dry and hygienic, reducing the probability of animals getting sick, thereby improving animal welfare and making management easier. By incorporating a detachable design for food and water supply devices, along with flexible baffles and normally closed drinking spouts, waste and contamination of water and food can be reduced, facilitating daily maintenance and ensuring food hygiene. Meanwhile, the cage top rails and sliding trolleys allow monitoring equipment to move and be positioned flexibly, enabling comprehensive observation and data collection of animal behavior without interference, thus providing data support for refined and intelligent feeding management.
