(Points of interest)
Bovine respiratory disease syndrome (BRDC: Bovine Respiratory Disease Complex. The same shall apply hereinafter) is caused by complex intertwining of pathogenic microorganisms such as viruses and bacteria and immune status due to stress, etc. Known as the industry's most economically ill disease (syndrome), respiratory disease syndrome is cattle infectious rhinotracheitis (IBR) due to stress sensitization to cattle due to transport, group formation and other environmental factors. In addition to viral infections such as bovine RS (bovine respiratory viral infection) disease, bovine parainfluenza (PI3), bovine viral diarrhea (BVD), Mnnheimia haemolytica, Pasteurella multocida, Haemophilus somni, the secondary or tertiary bacterial infections, such as Arcanobacterium pyogenes, is a respiratory disease is established by complex mixed infections as a result.

    In addition, bovine respiratory disease syndrome is involved in a progression process such as Mycoplasma bovis, and is considered as an exacerbating factor or a preceding factor that gives a disorder (see Non-Patent Document 1-1). In Japan, calf respiratory diseases are reported as mortality (4.76-5.30%) and disease incidence (37.89-40.67%) from 2010 to 26 (Non-patent Document 1). -2), and there is no tendency to decrease. In addition, according to the US Department of Agriculture respiratory disease survey, mortality due to respiratory disease in pre-weaned calves (see Non-Patent Documents 1-3) was 21.3% (1991), 24.5% (1996), 21. .3% (2002), 22.5% (2007), no decreasing trend is observed.

    Respiratory disease syndrome occurs most frequently in calves, and Mycoplasma bovis is an important causative bacterium (see Non-Patent Documents 1 to 4). It is a general syndrome such as fever, loss of appetite, and watery nasal discharge. In addition to respiratory symptoms, the emergence of pinna pits (including Mycoplasma bovis etc.) with otitis media has become a major problem (see Non-Patent Documents 1-5), and domestically breed 193 Japanese black breeding cattle On the farm, 64 (49.6%) of 129 calves born between April and November 2008 were diagnosed with otitis media (see Non-Patent Documents 1-6).

    Respiratory syndrome such as pneumonia in calves is a disease that has a great impact on the subsequent development and has a large economic loss. The loss includes: vaccine costs for prevention, treatment costs, developmental delay, If the increase in the mortality rate is added, it becomes a huge loss amount (see Non-Patent Document 1-3), and as a countermeasure for that, thorough ventilation management and hygiene management such as cow beds are more effective. Although prevention and treatment programs (vaccinations, antibiotics, etc.) are being implemented, as described above, bovine respiratory syndrome is a disease that has not been shown to decrease.

In the Japanese black cattle production farm, looking at the disease status by breeding scale, regardless of the farm scale, the incidence of digestive disease in calves has remained at over 30%. Incidence increases as farm size increases, and the incidence of respiratory disease by calf's mammal form is 0.48% on natural feeding farms and 1.24% on artificial feeding farms. It is 2.5 times or more (see Non-Patent Document 1-7).
The Japanese livestock industry is changing from small-scale breeding to large-scale breeding. Regarding calf diseases, respiratory diseases are on the rise more than digestive diseases, and preventive measures are required. .

(Conventional technology)
Under these circumstances, the artificial feeding technology has not been improved.
For example, as represented by what is proposed in Patent Document 1 (1) below, the vertical barrel portion of the nipple having a base portion extends upward from the base portion, curves, and has a shape reaching the upper end, The upper end of the barrel portion has a flat portion in the center, and the base portion includes a wall having an inner surface and an outer surface that form a cavity through which milk, milk substitute, and the like flow, and the nipple has an air vent, It is made of a flexible and elastic material such as natural rubber, synthetic rubber, thermoplastic elastomer, silicone, or other polymer compound. The total length from the bottom to the upper end of the nipple base is about 102 to 103 mm. About 75% of the total length of the nipple and preferably about 75 mm, the flat part at the upper end of the nipple has a peripherally curved peripheral part that fits the vertical part of the barrel part, and the diameter of the flat part is 5 to 7 mm, outside the peripheral curve The radius of the inner wall of the peripheral curve is 6.5 to 7.5 mm, the thickness of the wall extending downward is about 2.6 mm, and the thickness of the flat portion is about 2. mm. 4 mm, set to be thinner than the wall extending downward, the flat part is provided with an X-shaped slit, which can provide a nipple for supplying liquid to calves and other mammals, The length corresponding to the hollow nipple extending from the flange as seen in the patent document 1 (2) is about 60 mm, and the outer end of the nipple is closed by a concave member having a radius of about 5 mm. A slit having a length of 5 to 10 mm is provided in the center of the member, and a pair of webs for reinforcing the nipple from the inside are integrated on the inner wall of the nipple, and the animal is used in use. Suck or bite nipple The outer wall is squeezed and the outer wall is squeezed, stress is applied to the slit, the outer edge is deformed by the hardness of a pair of webs, and the slit is spread to allow liquid to flow more easily. Something like

However, the nipple for artificial feeding as shown in the former Patent Document 1 (1) has a total length from the bottom of the nipple base to the upper end of about 102 to 103 mm. Using these conventional full-length nipples, many calves often cause liquid feeds such as milk for milk to flow back into the nasal cavity or cause coughing. The nipple for artificial feeding shown in Patent Document 1 (2) has a length corresponding to the nipple of about 60 mm, but the proximal end of the nipple is the inner surface of the liquid source container. Therefore, depending on the outlet shape of the liquid source container, the lip of the calf may be buffered at the outlet of the liquid source container. , Mouth the whole nipple about 60mm in length Can not be included, the range of motion of the calf's tongue is limited, the nipple reaches the larynx or the vicinity of the tongue bulge over the entire nipple of about 60 mm in length, and smooth swallowing reflex is suppressed, only once Infant feeding milk may flow back into the nasal cavity or cough, and this non-conformance of the full length of a conventional artificial feeding nipple into the calf oral cavity prevents smooth swallowing. I came to think that it might be.

(Awareness of problems)
As described above, the nipples for various types of artificial feedings that have been proposed so far are so short that they do not reach the lingual septum because the total length of the nipple is so long that it reaches from the calf's lip to the vicinity of the tongue bulge. Applicants who quickly noticed that the calf's smooth swallowing reflex was hindered, often causing milk to flow back into the nasal cavity and coughing, for example, If the calf was born from a Holstein breed, the mother and the baby are separated immediately after birth, the colostrum is artificially sucked, and then artificial feeding is performed until it is shipped to the calf market within 30 to 60 days. Moreover, in Japanese black cattle, natural feeding by mother cows is performed for 3 days from birth, but on the fourth day the mother and the baby are separated and switched to artificial feeding is a general feeding method for cow calves, Calf artificial feeding, mother and child isolated Artificial feeding is carried out with a feeding bottle for 7 days, and then it is usually shifted to feeding with a bucket with a nipple or a feeding robot (the machine controls the feeding amount of the calf individual). , After the symptoms of suckling milk flowing back into the nasal cavity or coughing, the calf flows into the middle ear through the lingual tongue bulge and develops otitis media or respiratory disease syndrome As a result, the hypothesis that stress-induced decline in immunity leads to infection with pathogenic bacteria and leads to respiratory disease has led to doubts.

(Object of invention)
Therefore, this invention pays attention to the backflow to the nasal cavity of suckling milk and coughing that occurs before the occurrence of respiratory symptoms, and the shape and size of the suckling nipple that is considered to be the cause of this invention, It is closer to the udder and nipple of the mother cow, smoothly promotes the swallowing reflex of the calf, makes it possible to prevent backflow into the nasal cavity more safely, makes it possible to increase the amount of milk more reliably and maintain health, and it is efficient From the judgment that it is possible to develop a new artificial feeding technology that can raise calves in the future, the development and research have been started quickly, and trial and error over many years and many trials and experiments have been repeated.

(Related invention 1)
In relation to the nipple for artificial cows described above, the present invention also includes a swallowing aid for artificial cows that can be used by being mounted on a conventional artificial nipple teat.
That is, a barrel wall shape with a predetermined outer diameter, a predetermined length, and a predetermined wall thickness imitating the tip of the breast near the base of the mother cow's nipple, and the liquid feed supply port of the liquid feed supply source at the barrel wall base end On the other hand, a liquid feed of the liquid feed supply source is provided at the tip of the barrel wall opposite to the base end on which the mounting port of the barrel wall is provided. A nipple mounting opening of a predetermined diameter that can be mounted on the artificial feeding nipple of the same liquid feed supply source connected to the supply opening is opened, and a calf is placed around the nipple mounting opening at the tip of the barrel wall. The lip of the artificial nipple is closely attached, and the holding depth of the artificial nipple is sufficiently reached from the tip of the artificial nipple to the lingual septum from the tip of the lip of the calf and from the tip of the lip of the calf. A buffer barrel provided with a lip-restricted annular wall that can be regulated to a predetermined length that does not reach the tongue bulge; And an artificial feeding cattle swallowing aid to gist configuration.

    When the swallowing aid for artificial cows of the present invention is shown in different expressions, it imitates the tip of the breast near the base of the nipple of the mother cow, with an outer diameter of 50 to 80 mm, a length of 40 to 50 mm, and a wall thickness of 1 to The barrel wall has a 3 mm barrel shape, and is provided with an attachment port having a diameter of 50 to 65 mm that is detachable from the liquid feed supply port of the liquid feed supply source at the barrel wall base end. The liquid feed supply source connected to the liquid feed supply port of the liquid feed supply source is connected to the barrel wall tip opposite to the base end provided with the attachment port of the liquid feed supply source. A mouth of a nipple having a diameter of 10 to 35 mm that can be fitted in an opening is opened, and a lip of a calf is in close contact with the periphery of the mouth of the nipple at the tip of the barrel wall. The depth of the lip of the calf from the tip of the conventional artificial nipple A single piece made of a soft, waterproof, stretchable material with a lip-restricted annular wall that can be controlled to a length of 35 to 70 mm that can reach the tongue septum sufficiently from the end and does not reach the tongue bulge from the lip end of the calf It becomes the swallowing assistance tool for artificial cows which consisted of the buffer barrel body made into goods.

    The swallowing aid for artificial cows according to the present invention can be further expressed by imitating the shape of the tip of a breast near the base of the nipple of a mother cow, having an outer diameter of 50 to 80 mm, a length of 40 to 50 mm, and a wall thickness. The barrel wall has a shape of 1 to 3 mm, and a mounting port having a diameter of 50 to 65 mm that is detachable from the liquid feed supply port of the liquid feed supply source is provided at the base end of the barrel wall. For the conventional artificial feeding nipple of the liquid feed source connected to the liquid feed supply port of the liquid feed supply source at the tip of the barrel wall opposite to the base end provided with the mounting port of the barrel wall A conventional nipple for teat with a lip of a calf in close contact with the outer periphery of the nipple-mounted mouth at the tip of the barrel wall. From the tip of the conventional artificial nipple Made of soft, waterproof and stretchable material with a lip-restricted annular wall that can be controlled to a length of 35 to 55 mm that can reach the tongue septum sufficiently from the lip tip of the calf and does not reach the tongue bulge from the lip tip of the calf It becomes the swallowing assisting device for artificial cows which consists of the buffer barrel made into the integrally molded product.

    As described above, according to the nipple for artificial cows of the present invention, unlike the conventional ones, the normal characteristic swallowing configuration as described above enables normal swallowing reflexes of the calf, and only once. The liquid feed flows back into the nasal cavity and flows into the middle ear via the tubal tongue protuberance, thus preventing otitis media and the liquid feed entering the respiratory tract and causing respiratory disease syndrome. It is possible to secure a sufficient amount of feeding more safely, smoothly and efficiently, and the incidence of respiratory disease syndrome, ear drop pit and death rate due to respiratory disease syndrome are Compared to the use of nursing nipples, it can be significantly improved and more stable and healthy calves can be raised. Improved and during calf feeding Significantly reduces economic losses, in which exhibits the outstanding effect that it is possible to realize the much stable calf development.

    The nipple has an outer diameter of 10 to 35 mm simulating that of a mother cow, and a length of 35 to 35 that does not reach the tongue bulge from the calf's lip tip while sufficiently reaching the tongue septum from the calf's lip tip. 70 mm (more desirably, 35 to 55 mm) cylindrical wall shape, and a tip wall having a papillary hole at the tip of the cylinder wall is the most suitable dimension for the average oral condition of the calf. , And further, the buffer barrel portion is shaped like a barrel wall with an outer diameter of 65 to 80 mm and a length of 65 to 80 mm, imitating the tip of the breast near the base of the nipple of the mother cow, While providing a mounting opening to be detachable with respect to the liquid feed supply port of the liquid feed supply source, at the tip of the barrel wall opposite to the base end provided with the mounting port of the barrel wall, After integrating the base end so that the inside of each other communicated, Around the outer periphery of the connecting portion between the tip of the barrel wall and the proximal end of the nipple, the tailing depth of the nipple by a calf is set to 35 to 70 mm (more preferably, 35 to 55 mm) which is the length of the nipple. According to the nipple for artificial cows of this invention, which is provided with a lip-restricted annular wall that can be regulated), it is of the most suitable shape and size for the intraoral conditions of more cows, The lip-restricted annular wall regulates the position of the lip of the calf, making it possible to more reliably prevent liquid feed from flowing back into the nasal cavity and coughing into the airways and lungs. It is possible to prevent the onset of auricular appendix, otitis media, respiratory disease syndrome, etc., and to realize further excellent calf breeding.

    In addition, the artificial milking cow according to the present invention is configured such that the inside of the cylindrical wall shape of the nipple is a nipple tank, the inside of the barrel wall shape of the buffer barrel is a dairy tank, and the dairy tank is connected to the nipple tank. According to the nipple for use, an appropriate amount of liquid feed without excess or deficiency is supplied from the nipple tank for each swallowing movement of the calf, and with the restoration of the shape of the nipple tank (nipple), Since the milk tank in the buffer barrel section automatically supplies new liquid feed sequentially to the nipple tank, it will realize natural suckling closer to the breast and nipple of an actual mother cow. The effect of preventing the backflow of liquid feed to the nasal cavity and coughing can be further enhanced, the swallowing reflex can be promoted more smoothly, and a larger amount of feeding can be given.

    According to the nipple for artificial cows of the present invention in which the entire nipple and the buffer barrel are integrally molded products made of soft, waterproof and stretchable material, the entire nipple and mouth of the calf have elasticity. It is possible to protect the lip of the calf by protecting the impact of the lip of the calf and the lip limiting annular wall of the buffer barrel. In addition, the liquid feed supply port of the liquid feed source equipped with the nipple for artificial cows is more surely protected, and the diameter of the mounting port of the buffer barrel portion is regulated to 50 to 65 mm. By doing so, it can be detachably attached to a liquid feed supply port of a baby bottle, a baby bucket, a feeding robot and other various liquid feed supply sources, and the versatility and economy can be further improved. .

    And according to the swallowing aid for artificial cows of this invention, the detachable attachment to the conventional artificial nipple teat attached to the liquid feed supply port of the conventional liquid feed supply source, etc. Since it is possible to achieve substantially the same effect as the teat for artificial cows according to the present invention, the existing conventional teat for artificial breasts can be effectively used as it is without being discarded. Since it can be manufactured and provided with a smaller size, lighter weight, and lower price than the nipple for babies, an excellent effect that the economic burden on the purchaser can be greatly reduced is obtained.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The artificial baby cow nipple can be detachably attached to the liquid feed supply port of at least one liquid feed supply source of baby equipment such as a baby bottle, a baby bucket and a baby robot. The outer shape of the nipple that resembles the tip of the nipple and the tip of the nipple that follows the tip of the breast is provided, and the liquid feed supplied from the liquid feed supply port through the inside can be supplied from the tip of the portion simulating the nipple. It is made of a soft and waterproof material that must be integrated with the buffer barrel imitating the vicinity of the maternal cow's nipple and the nipple imitating the maternal nipple. Furthermore, it is desirable to have elasticity, for example, it should consist of at least one material of natural rubber, synthetic rubber, silicone rubber and isoprene rubber. It is possible.

    The nipple, like the mother's nipple, is capable of suckling and has the function of facilitating the calf's swallowing reflex smoothly, reaching the lingual septum sufficiently from the calf's lip tip. In addition, it should be of a size and shape that does not reach the tongue bulge from the calf's lip tip, and more specifically, from the calf's nipple tip, and from the calf's lip tip It should have a cylindrical wall shape with a predetermined length that does not reach the tongue bulge from the lip tip of the calf, while reaching the septum of the tongue sufficiently, and it must be provided with a tip wall having a nipple hole at the tip of the tube wall, More specifically, the outer diameter is 10 to 35 mm simulating the nipple shape of a mother cow, and the length does not reach the tongue bulge from the calf lip tip while sufficiently reaching the tongue septum from the calf lip tip. It has a cylindrical wall shape of 35 to 70 mm and has a nipple hole at the tip of the cylindrical wall. End walls should be provided, and as shown in the examples described later, an outer diameter of 10 to 35 mm, more preferably an outer diameter of 10 to 20 mm, which mimics the nipple shape of a mother cow, and a calf A cylindrical wall shape having a length of 35 to 70 mm and a thickness of 1 to 3 mm that does not reach the tongue bulge from the calf's lip tip. The inside of the cylindrical wall shape serves as a nipple tub. It is desirable that the cylindrical wall is made of a soft waterproof material provided with a spherical tip wall having a nipple hole drilled.

    The nipple hole of the nipple has a function of allowing the calf to drink liquid feed from the tip of the nipple, and the liquid feed supplied from the liquid feed source to the teat for artificial cows is supplied to the nipple hole. It is desirable that the hole has a small diameter so that it does not impose a burden on the swallowing movement of the calf, rather than increasing the diameter. It is normally closed like a slit or valvular, and can be opened when ingested by a calf, with one or more nipple holes provided As shown in the embodiments to be described later, the cross-shaped or X-shaped slits can be used, and C, E, F, J, K, L, M, N, S, Among various slit shapes such as T, U, V, W, Y shape and * mark shape It is possible Re or to that of one shape.

    The teat tank of the nipple connects the milk tank and the nipple hole in the buffer barrel, and allows the liquid feed supplied from the liquid feed source to the teat for artificial cows to reach the nipple hole. When swallowing, it is responsible for the ability to supply liquid feed through the nipple hole, similar to the nipple of a mother cow, and the calf can suck and drink safely with a single swallowing movement. The capacity of the calf should be sufficient to allow the accumulation of an appropriate amount of liquid feed that is sufficient for the calf, and the nipple tank emptied by compression and sucking of the calf is the same. Gravity acting on the liquid feed in the buffer barrel milk tank placed above the nipple tank according to the relaxation of the compressive force and sucking power accompanying swallowing of the milk, when using a feeding robot having a feeding pump At least one of pressure applied by the pump and elastic return force of the nipple Thus, it is possible to automatically receive the liquid feed from the milk tank in the buffer barrel.

    The buffer barrel portion allows the calf's lip tip position to be regulated near the proximal end of the nipple when the calf includes the nipple of the nipple for artificial cows in the mouth. The nipple of the artificial dairy cow has a teat that is opposite to the one that has a nipple. A barrel wall shape having a predetermined outer diameter and a predetermined length simulating the tip of the breast is provided, and a mounting opening that is detachable from the liquid feed supply port of the liquid feed supply source is provided at the base end of the barrel wall On the other hand, after the base end of the nipple is integrated with the tip of the barrel wall that is opposite to the base end provided with the mounting opening of the barrel wall so that the insides of the barrels communicate with each other, the barrel wall The tailing depth of the nipple by the calf is restricted to a predetermined length of the nipple on the outer periphery of the connection portion between the distal end and the proximal end of the nipple. Must be such that those having a lip limiting annular wall to ability.

    As shown in the examples described later, it simulates the shape of the breast tip near the base of the nipple of the mother cow, and has a barrel wall shape with an outer diameter of 65 to 80 mm, a length of 65 to 80 mm, and a wall thickness of 1 to 3 mm. The barrel wall shape is a dairy tank, and the barrel wall base end is provided with a mounting port that is detachable from the liquid feed supply port of the liquid feed supply source, while the barrel wall mounting port is provided with a mounting port.
