Description

Technical Field

[0001] This invention relates to the field of livestock breeding equipment technology, and more specifically, to an automatic nursing machine specifically designed for suckling rabbits. Background Technology

[0002] Currently, in domestic rabbit farming, pre-weaned rabbits are nursed by their mothers for about 30 days. Most mother rabbits have eight teats and can typically raise 4-8 kits. Taking the most intensive breeding model as an example, the theoretical maximum number of weaned rabbits per mother per year is 64. However, there are four main challenges:

[0003] 1. During the nursing period, baby rabbits often starve to death due to insufficient milk supply.

[0004] 2. After the baby rabbits are 20 days old, the mother rabbit's nutrition declines, she loses weight rapidly, which affects the nursing of the current litter and the development of the fetuses in the next litter.

[0005] 3. The number of kits a mother rabbit can nurse can only be limited to 8 or less, depending on the number of her teats; any kits that a mother rabbit produces more than 8 must be culled.

[0006] 4. The temperature and humidity inside the birthing box are mainly maintained by the bedding material and wool, which often results in the animals freezing or being trampled to death.

[0007] Currently, the production efficiency of rabbit farming in my country remains low, resulting in the cost of net rabbit meat far exceeding that of broiler chickens and lean pork. In contrast, the chicken industry utilizes artificial incubation of eggs, greatly improving production efficiency; and in dairy farming, the practice of artificially feeding calves has significantly reduced costs.

[0008] To break through the development bottleneck of the rabbit farming industry, adopting a centralized, mechanical nursing method for baby rabbits after birth, separated from their mothers, is an important issue that can significantly increase the productivity of mother rabbits and reduce feeding costs.

[0009] There are three major problems to be solved in the complete artificial feeding of baby rabbits:

[0010] 1. Nutritional Sources. The formula uses reconstituted milk in the early stages of lactation, followed by liquid milk replacer, and then transitions to complete pelleted feed before weaning. This accelerates growth and development during lactation and avoids growth retardation caused by weaning.

[0011] 2. Environmental Control. The brooder box fully meets the needs of rabbits of different ages. Located in a dedicated brooder room, it is equipped with automatic control systems for temperature, humidity, air quality, harmful gases, light, and noise, as well as a sterilization system, creating the most suitable nesting environment for the rabbits' growth. No bedding or wool is used in the brooder box, ensuring cleanliness and hygiene.

[0012] 3. An automatic nursing machine for baby rabbits, which is the technical solution to be provided by this invention. Summary of the Invention

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0033] Reference Figure 1-2 The automatic nursing machine for suckling rabbits described in this embodiment includes a frame, several brooder box assemblies 1, a milk supply and nursing assembly 2, and a drive assembly that drives each brooder box assembly 1 to circulate on the frame.

[0034] The frame includes two upright plates 6, one on the left and one on the right. Several half-shafts 4 are fixed to the inner sides of each upright plate 6. Each half-shaft 4 is equipped with a sprocket. A chain 5 is mounted on each of the sprockets on the left and right upright plates 6. In this embodiment, four half-shafts 4 are fixed to the inner sides of each of the two upright plates 6, and the four half-shafts 4 are arranged in a rectangular pattern.

[0035] The drive assembly includes a motor reducer 10 and a drive shaft 9. The motor reducer 10 is fixed to the bottom of the frame, and the drive shaft 9 is mounted on the power output end of the motor reducer 10. Its two ends are respectively connected to two lower half-shafts 4. Specifically, drive sprockets are fixedly installed on both ends of the drive shaft 9, and transmission sprockets are fixedly installed on the two half-shafts 4 near the drive shaft 9. The two drive sprockets drive the two transmission sprockets via drive chains 8. The sprockets on the two half-shafts 4 near the drive shaft 9 are driving sprockets 7, and the remaining sprockets are driven sprockets 3.

[0036] like Figure 3 , 4 As shown, the brooding box assembly 1 includes a brooding box body 13 and a rotating shaft 11. The top center of the left and right side plates of the brooding box body 13 is fixedly connected to the rotating shaft 11, and the two ends of the rotating shaft 11 are rotatably connected to the left and right side rotating chains 5 respectively.

[0037] The inner cavity of the brooder box 13 is evenly divided into several brooder cage positions by several partitions 14. Each brooder cage position is further divided into two brooder units by a movable insert 15. The partitions 14 are fixedly connected to the inner wall of the brooder box 13, and the movable insert 15 is perpendicular to the partitions 14 and is inserted into the middle of each brooder cage position. A brooder box cover 12 is installed on the top of the brooder box 13. The brooder box cover 12 has a perforation for inserting a sucking nipple, which also serves as a ventilation hole. A rabbit bed 16 is laid at the bottom of the brooder box 13 and has a manure drain hole. A manure tray 17 is installed below the brooder box 13 to collect the rabbit manure.

[0038] like Figure 1 ,2 As shown, the milk supply and nursing assembly is provided with upper and lower parts on the operating route of the brooder box assembly 1.

[0039] like Figure 5 , 6 As shown, the milk supply and feeding assembly includes a milk inlet tube 23, a milk supply tube 29, and a sucking nipple. Several milk supply tubes 29 are evenly connected to the bottom end of the milk inlet tube 23, and a sucking nipple is installed at the bottom end of each milk supply tube 29. Specifically, there are two milk inlet tubes 23, which are parallel to each other. The bottom of each of the two milk inlet tubes 23 is vertically fixed with a milk supply tube 29 that corresponds one-to-one with the nursing unit. The sucking nipple includes a stainless steel nipple 210 fixedly installed on the bottom end of the milk supply tube 29 and a latex nipple 211 fixedly wrapped around the stainless steel nipple 210.

[0040] The milk supply and breastfeeding assembly also includes a rinsing water pipe 22, which is located above the two milk delivery pipes 23 and is arranged in a triangular pattern with the two milk delivery pipes 23. The bottom of the rinsing water pipe 22 is evenly provided with spray holes corresponding to each sucking nipple. The rinsing water pipe 22 and the two milk delivery pipes 23 are connected by a connecting bracket 26 to form an integral frame structure. Both ends of the integral frame structure are fixedly connected to sliders 21 that can move up and down reciprocally. The up and down reciprocating movement of the sliders 21 can be achieved using conventional techniques in the art, which will not be described in detail here.

[0041] The milk supply and nursing assembly 2 is provided with a cylindrical outer cover 28 that can rotate 180° back and forth, and the top of the cover has a through hole that corresponds to the brooding unit. A dust cover 25 is fixed on the top of the outer cover 28, and a sterilization device 24 (an ultraviolet germicidal lamp or an ozone sterilization device is used in this embodiment) is fixedly installed on the bottom of the dust cover 25. The sterilization device 24 is located above the through hole of the outer cover.

[0042] The outer cover 28 has a water outlet at its bottom end, and a water outlet interface 212 is fixed below the water outlet. During installation, the outer cover 28 is tilted at a certain angle, with the front higher than the back. This way, the water after rinsing the nipple falls to the bottom of the outer cover 28, flows into the water outlet, and is discharged through the water outlet interface 212.

[0043] The assembly method of the outer cover 28 can refer to the common roller structure. A drive gear 27 is fixed on the outer wall of one end. The drive gear is driven by an external motor (a power gear that meshes with the drive gear 27 is fixedly installed on the power output shaft of the motor), which enables the outer cover 28 to rotate 180° back and forth.

[0044] This invention only provides the mechanical structure of the automatic nursing machine specifically for suckling rabbits. When it is put into production, a matching computer intelligent control system is required to intelligently control the drive assembly to drive the brooder assembly along the chain, as well as the actions, milk supply, rinsing, and disinfection of the milk supply and nursing assembly, without the need for manual operation.

[0045] 1. Three days after the baby rabbits were born at the same time and began receiving colostrum from their mothers, they were manually sorted according to their weight. They were then disinfected, sorted, and placed in the various nursery units of the nursery box 13 to ensure lateral balance when the nursery box 13 rotates vertically. When the baby rabbits are ten days old, the movable inserts 15 in the middle of each nursery cage can be removed to expand their activity space.

[0046] 2. During operation, the motor reducer 10 is started, driving the power shaft 9. The power shaft 9 drives the half shaft via the drive chain 8, which in turn drives the drive chain 5 via the drive sprocket 7. The drive chain 5 drives the brooding box 13 to move. The drive shaft 11 fixed on the brooding box 13 is movably connected to the drive chain 5, so that the brooding box 13 always maintains a vertical downward state by its own weight during rotation and turning. When the brooding box 13, which is receiving milk, moves to the position below the upper and lower milk supply and feeding assembly (milking position), the motor reducer 10 stops.

[0047] 4. At this time, the outer cover 28 rotates 180° under the drive of the drive gear 27, flips up and down, and the through hole faces down to correspond to each of the breeding units; the milk delivery tube 23 moves downward under the drive of the slider 21, and the sucking nipple extends out of the outer cover 28 from the through hole, and then extends into the breeding unit of the breeding box 13 through the perforation on the breeding box cover 12, and the baby rabbits begin to look for the sucking nipple to suckle.

[0048] 5. After the sucking nipple provides milk for a few minutes (the feeding time for baby rabbits is generally 3-4 minutes), the milk delivery tube 23 moves upward under the action of the slider 21, the sucking nipple retracts into the outer cover 28, and the outer cover 28 rotates 180° under the action of the drive gear 27, returning to its original position.

[0049] 6. Water is supplied to pipe 22, and water is sprayed from various nozzles to rinse the latex nipple 211. At the same time, ultraviolet lamps are turned on for sterilization (or ozone-containing air is passed through for sterilization). This completes one cycle of operation.

[0050] 7. Restart the motor reducer 10 to keep the chain 5 running. After the next brooder box 13 is moved to the brooder position, the motor stops and the baby rabbits in the brooder box 13 are fed milk.

[0051] 8. The motor reducer works in a regular cycle for 10 cycles until the feeding of all the baby rabbits is completed.

[0052] 9. After the entire breastfeeding session is completed, perform the cleaning and sterilization procedures for the milk supply and breastfeeding assembly, as follows:

[0053] (1) The milk delivery tube 23 is flushed with water to clean the residual milk; the water pipe 22 is flushed with water to rinse the latex nipple 211; the waste liquid after cleaning is collected in the inclined outer cover 28 and discharged from the water outlet 212 at the end.

[0054] (2) The outer cover has 28 tubes for hot air circulation to dry the milk supply and breastfeeding assembly.

[0055] (3) Use ultraviolet lamps to irradiate (or pass ozone-containing air) to thoroughly sterilize and disinfect the milk supply and breastfeeding assembly.

[0056] (4) The feces collection tray 17 is located below the brooding box 13, which can effectively prevent the lower brooding box from being contaminated and is also convenient to clean.

[0057] 1. Three-day-old baby rabbits, after sterilization and sorting, are placed in nursery box 13. It is essential to ensure that all baby rabbits in the same box are of similar weight and size to facilitate management and handling, and to guarantee consistent growth. Special care is provided to smaller and weaker baby rabbits to ensure their survival (previously, baby rabbits from mothers who produced too many offspring or those that were weak were culled), thus improving the survival rate of newborn baby rabbits.

[0058] 2. An automatic nursing machine is installed in a dedicated nursery room, with unified control over temperature, humidity, ventilation, and air purification. Because the temperature and humidity in the nursery room and nursery boxes are adequately maintained, there is no need for bedding straw or fur in the nursery box 13, eliminating the risk of infection from bacteria in the straw and fur, and simplifying the disinfection process for the rabbit nests. Furthermore, the manure collection tray 17 is located below the nursery box 13, effectively preventing contamination of the lower nursery boxes and facilitating cleaning. This effective environmental protection against disease, pollution, and pests ensures the healthy growth and development of the baby rabbits.

[0059] 3. The automatic nursing machine has a multi-layer structure, small size and large capacity. Each automatic nursing machine can feed hundreds to thousands of baby rabbits. A small nursery can hold several to a dozen automatic nursing machines, which saves breeding space and facilitates manual management. It is suitable for the intensive breeding management model of all-in and all-out in rabbit production.

[0060] 4. Separating baby rabbits from their mothers eliminates the chance of germs and viruses carried by the mother rabbits spreading to the baby rabbits; it also prevents the mother rabbit from jumping in and out of the nest while nursing, which could cause injury to the baby rabbits by trampling or biting them; and separating the baby rabbits from their mothers also prevents the baby rabbits from chasing after the mother rabbit to nurse, thus avoiding disturbing the mother rabbit's rest.

[0061] 5. The use of specialized baby rabbit milk powder and automatic nursing machines ensures both the quality and temperature of the milk, as well as a sufficient supply, compensating for insufficient milk from the mother rabbits. This accelerates the growth of the baby rabbits, resulting in healthier, faster weight gain, and earlier weaning and market availability. Artificial feeding, especially for weak or underweight baby rabbits, allows for individualized and meticulous management, increasing the frequency of feedings to ensure they are well-fed and grow healthily. It completely avoids the natural competition among baby rabbits during nursing, which can lead to weaker rabbits not getting enough milk or even death. In production examples, an average mother rabbit nurses eight baby rabbits; in some litters, four baby rabbits died, leaving four remaining.

[0062] 6. Artificially formulated milk powder can be customized according to the age, growth status, and needs of the baby rabbits, offering convenience and flexibility. Using cow's milk as the base milk results in lower production costs.

[0063] 7. After the baby rabbits have consumed their mother's colostrum at 3 days old, they are separated from their mother. The mother rabbit will then stop nursing and return to estrus, making her ready for mating again. In this way, a single mother rabbit can breed 11 litters a year, contributing 122 weaned kits annually, thus increasing the number of litters per year. The nutrients the mother rabbit would have used to nurse her kits are now used for the development of the embryos in the pregnant rabbit, which benefits the mother rabbit's recovery, increases the weight and health of the newborn kits, and ultimately increases the number of kits the mother rabbit will produce annually.

[0064] 8. All automatic breastfeeding machines are made of stainless steel, ensuring accurate positioning, smooth and flexible operation, low accident rate, and easy cleaning and sterilization. The milk supply and feeding assembly is small in size, simple in structure, water-saving, easy to clean, and easy to keep warm and sterilize.

[0065] 9. The application of automatic nursing machines specifically for baby rabbits can greatly save manpower in the management and operation of nursing baby rabbits, reduce the breeding and management costs of baby rabbits, and at the same time, it can achieve a large number of litters, good health of baby rabbits at birth, no need to cull weak rabbits, low mortality rate, fast growth and development of baby rabbits, early market launch, saving labor and time, and greatly improving the production efficiency of rabbit breeding.

[0066] In summary, after the application of the automatic nursing machine described in this invention, baby rabbits are artificially fed, freeing up the mother rabbits. As long as the lactation period is controlled within 15 days, mating can be carried out the day after parturition throughout the year, achieving a 32-day breeding cycle, producing 11.4 litters per year, with an average of 12 kits per litter, contributing 136.8 weaned kits per year. The production cycle is shortened from more than 46 days to 32 days. Weak kits with congenital developmental deficiencies can be quickly restored to strength by providing sufficient restorative milk and postnatal nutritional supplementation, ensuring that the mother rabbit's productivity is not wasted.

[0067] The above are merely embodiments of the present invention and are not intended to limit the scope of the patent of the present invention. Any equivalent structure made using the contents of the present invention's specification and drawings, whether directly or indirectly applied to other related technical fields, is also within the scope of patent protection of the present invention.
