Abstract

<P>PROBLEM TO BE SOLVED: To provide an automatic suckling apparatus to enable sufficient supply of milk even to a young calf, a small calf having poor sucking force or a calf unaccustomed to a teat member. <P>SOLUTION: A mixer 1 is connected to a tank 3 through a liquid pipe 2. A pump 4 for lifting the milk in the mixer 1 to the tank 3 is placed in the middle of the liquid pipe 2. A teat member 6 is connected to the tank 3 through a liquid pipe 5. The teat member 6 is fixed to a frame 7 placed on the ground. The tank 3 is placed at a level higher than the teat member 6. When a calf (a) holds the teat member 6 and sucks the teat, the milk falls down from the tank 3 in a state close to a spontaneously falling state and, accordingly, the calf can drink the milk simply by sucking the teat with an extremely weak sucking force. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は、子牛にミルクを給与するための自動哺乳装置に関するものである。
【0002】
【従来の技術】
農水省畜産統計によると、平成14年2月現在の国内酪農家戸数は31,000戸と5年前に比較して20%以上減少している。一方、使用頭数は170万頭強で、9%の減少に過ぎない。すなわち1戸当りの使用頭数は増加しており、今後さらに増加すると考えられる。
【0003】
従来、子牛は分娩後直ぐに母牛から引き離され、哺乳ビンやバケツで人口哺乳されているが、規模拡大により搾乳頭数が増えれば必然的に分娩子牛も増えることとなり、その哺乳にかかる労力と手間が酪農家の大きな負担となっている。また、同様に肉用肥育牛の生産農家の規模拡大も進んでおり、哺乳作業の省力化が求められている。
【0004】
そこで、近年、自動哺乳装置を導入して哺乳作業の省力化を図るようになった。この自動哺乳装置は、これまで個別管理で人手に頼っていた哺乳作業を全自動で行うもので、1台で最大50〜60頭の群管理での哺乳が可能であり、欧米で開発され国内にも平成12年の時点で200台以上が導入されている。
【0005】
自動哺乳装置を用いた自動哺乳は、従来の個別管理による人工哺乳と比較すると以下のような利点がある。
1)人工哺乳は、数頭分のミルクをまとめて調製するので、一定の温度で給与することが難しいが、自動哺乳は、必要量だけのミルクを調製して直ちに給与するため常に一定の温度で給与できる。
2)人工哺乳の場合は、1日朝夕2回給与で、1回当りの給与量が多くなり下痢を起こし易いが、自動哺乳の場合は、少量を何回にも分けて給与できるので下痢の発生を抑えることができる。
3)1回当りに満腹となるようなミルク量を飲むことが出来ないので、固形飼料の食い込みが早くなる。
4)一定の広さをもった放し飼いであるので、運動量が多くなり、その結果、足腰が丈夫になる。
5)従来は離乳後群飼に移行していたため、離乳と群飼のストレスが重なり体調を崩しやすかったが、哺乳期から群飼なので離乳時のストレスが軽減される。
【0006】
このような自動哺乳を行う自動哺乳装置の例を図2に示す。この図に示す自動哺乳装置は、ミルクを調製するミキサー11と、子牛がミルクを吸引する乳首部材12と、ミキサー11と乳首部材12とを連結する送液管13とを有し、また、乳首部材12は、子牛の口の高さと略同頭となるように枠体14に固定されている。このような自動哺乳装置においては、子牛aが乳首部材12を口に含み、吸引することによりミキサー11からミルクが給与されるものである(非特許文献1参照。)。
【0007】
【非特許文献1】
“An Evaluation of Two Management Systems for Rearing Calves Fed Milk Replacer” Journal of Dairy Science Vol.80,No.10 1997
【0008】
【発明が解決しようとする課題】
ところで、自動哺乳装置は群飼での哺乳が大前提であるので、子牛の大小や強弱の差がある程度生じるのはやむを得ない。しかしながら、従来の自動哺乳装置では、ミキサーで調製したミルクを子牛に直接吸引させることにより哺乳しているため、若齢の子牛や吸引力の弱い小さな子牛では、ミルクを飲むのに時間がかかり、一定時間内に飲みきれないことが多かった。特に、自動哺乳に移行した直後では顕著で、そのことが自動哺乳初期の発育の停滞を招いていた。
【0009】
本発明は、以上の問題点を解決し、若齢や小さい子牛であっても、大きく強い子牛と同様に、十分ミルクを飲むことができるようにした自動哺乳装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
本発明者は、上記目的を達成するために鋭意検討し、乳首部材にミルクを供給するミルク供給源を乳首部材より上方に配置し、ミルク供給源から自然落下に近い形で乳首部材にミルクを供給することにより、吸引力の弱い子牛であっても、十分にミルクを飲めることを見出し、本発明を完成させたものである。
【0011】
すなわち、本発明による自動哺乳装置は、子牛にミルクを吸引させるための乳首部材と、この乳首部材にミルクを供給するミルク供給源とを有し、このミルク供給源が乳首部材より高所に配置されていることを特徴として構成されている。
【0012】
本発明の自動哺乳装置においては、ミルク供給源が乳首部材より高所に配置されており、ミルク供給源のミルクは乳首部材に自然落下して行く。したがって、乳首部材を吸う吸引力が小さい場合であっても、乳首部材から十分なミルクを飲むことができる。
【0013】
【発明の実施の形態】
本発明はミルク供給源が、乳首部材より高所に配置されている。このミルク供給源は、ミルクを調製するミキサーであっても、ミキサーからミルクが送られ一時的に貯溜するタンク等であってもよい。タンクを用いる場合は、ミキサーとタンクとをポンプ等を介して連結し、ミルクをタンクに搬送するようにすることができる。タンクを用いると、タンクに所定量を貯溜することができるので、子牛に1回で給与するミルクの量を正確に制御することができる。
【0014】
ミルク供給源の高さは、一般に、乳首部材の高さが約75cm(子牛の口の高さ)であるので、120cm以上(高低差45cm以上)であることが好ましい。
【0015】
本発明による自動哺乳装置の一実施形態を図面を参照して説明する。
図1は、自動哺乳装置の全体模式図である。この図において、1はミルクを調整するミキサーで、このミキサー1は、送液管2により1リットル程度(1回で子牛に給与する量)の容量を持つタンク3に連結されており、送液管2の途中には、ミキサー1のミルクをタンク3に押し上げるためのポンプ4が設けられている。また、タンク3には、送液管5を介して乳首部材6が連結されており、この乳首部材6は地面に設置された枠体7に固定されている。そして、タンク3は、乳首部材6の高さより高所に配置されている。
【0016】
以上のような自動哺乳装置においては、子牛aが乳首部材6をくわえ吸引すると、ミルクはタンク3より自然落下に近い状態で落ちてくるので、極めて小さい吸引力で吸引するだけで、子牛はミルクを飲むことができる。
【0017】
【実施例】
[実施例1]
図1に示す自動哺乳装置を用いた。なお、乳首部材6の高さは75cmで、タンク3の高さ(地面からタンク3の底までの長さ)は120cmとした。
【0018】
[従来例1]
図2に示す従来の自動哺乳装置を用いた。なお、ミキサー及び乳首部材は、実施例1と同一のものを使用した。
【0019】
[哺乳試験]
10頭の哺乳子牛を割り当て、14日間下記の条件で哺乳試験を行った。
<1回当りの条件>
代用乳量:125g
温 水 量:900cc
哺乳時間:120秒
<1日当りの条件>
哺乳回数:4回
哺乳間隔:2時間

【0023】
上記結果より、自動哺乳開始直後の哺乳回数は実施例1及び従来例1とも同様で、子牛が哺乳場所にやって来る頻度には方式の違いによる影響は無かった。
【0024】
しかし、表1から明らかなように、実施例1は飲み残し量が少なく、かつ、全頭が哺乳プログラム通りにミルクを飲むことができたのは7日目以降であった。これに対し、従来例1は飲み残し量が多く、かつ、全頭が哺乳プログラム通りにミルクを飲むことができるようになったのは8日目以降であった。
【0025】
また、表2から明らかなように、発育も飲み残し量の結果を反映しており、開始7日後までは実施例1が従来例1を大きく上回っている。
【0026】
以上の結果、従来例1は、導入直後で乳首部材に不慣れな子牛や吸引力の弱い子牛がミルクを飲みきれないと考えられ、その結果、自動哺乳初期の発育の停滞を招くおそれがある。しかしながら、実施例1は、ミルクは高低差を利用しているため大きな吸引力を必要とせず、弱い子牛でもミルクを十分に飲むことができるので、自動哺乳初期においても健全な発育を促進することが出来た。
【0027】
【発明の効果】
本発明は、若齢の子牛や、吸引力の弱い小さな子牛や、乳首部材に不慣れな子牛であっても、ミルクを十分に摂取することができ、その結果、健全な発育を促進することができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an automatic feeding apparatus for feeding milk to calves.
[0002]
[Prior art]
According to the Ministry of Agriculture and Livestock Statistics, the number of domestic dairy households as of February 2002 was 31,000, a decrease of more than 20% compared to five years ago. On the other hand, the number of used animals is just over 1.7 million, only a 9% decrease. That is, the number of used animals per house is increasing, and it is thought that it will further increase in the future.
[0003]
Conventionally, calves are separated from their mothers immediately after calving, and the population is fed in feeding bottles or buckets. This is a heavy burden for dairy farmers. Similarly, the scale of farmers producing beef fattening cattle has been increasing, and labor saving of feeding work is required.
[0004]
Thus, in recent years, an automatic feeding apparatus has been introduced to reduce labor in feeding operations. This automatic feeding device performs feeding operations that had previously relied on humans for individual management in a fully automatic manner. One unit can feed a group of up to 50 to 60 animals, and has been developed in Europe and the United States and developed in Japan. As of 2000, more than 200 units have been introduced.
[0005]
Automatic feeding using an automatic feeding device has the following advantages as compared with conventional artificial feeding by individual management.
1) Artificial feeding is difficult to feed at a constant temperature because it prepares several milks at a time, but automatic feeding is always at a constant temperature because only the required amount of milk is prepared and fed immediately. Can be paid.
2) In the case of artificial feeding, two doses per day in the morning and evening will increase the dose per dose and tend to cause diarrhea. However, in the case of automatic feeding, small doses can be divided into any number of doses. Occurrence can be suppressed.
3) Since it is not possible to drink a sufficient amount of milk per serving, the bite of solid feed is accelerated.
4) Since it is a free-ranging animal having a certain size, the amount of exercise increases, and as a result, the legs and legs become strong.
5) Conventionally, the baby was moved to the group after weaning, so that the stress of the weaning and the group were overlapped and the physical condition was easily broken.
[0006]
FIG. 2 shows an example of an automatic feeding apparatus for performing such automatic feeding. The automatic feeding apparatus shown in this figure has a mixer 11 for preparing milk, a nipple member 12 for calf sucking milk, and a liquid feed pipe 13 for connecting the mixer 11 and the nipple member 12, and The nipple member 12 is fixed to the frame 14 so as to be substantially the same height as the calf's mouth. In such an automatic feeding apparatus, the calf a includes the nipple member 12 in the mouth, and the milk is supplied from the mixer 11 by suction (see Non-Patent Document 1).
[0007]
[Non-patent document 1]
"An Evaluation of Two Management Systems for Reading Calves Fed Milk Replacer" Journal of Dairy Science Vol. 80, no. 10 1997
[0008]
[Problems to be solved by the invention]
By the way, since automatic feeding is premised on feeding in a group, it is inevitable that a difference in calf size and strength will occur to some extent. However, in a conventional automatic feeding apparatus, milk prepared by a mixer is sucked directly into calves to feed, so that young calves and small calves with weak suction power take time to drink milk. And it was often impossible to drink within a certain amount of time. In particular, this was remarkable immediately after the shift to automatic feeding, which led to a stagnation in the early stage of automatic feeding.
[0009]
An object of the present invention is to solve the above-mentioned problems and to provide an automatic feeding device that enables sufficient drinking of milk as well as large and strong calves, even for young and small calves. And
[0010]
[Means for Solving the Problems]
Means for Solving the Problems The present inventor has studied diligently to achieve the above object, arranges a milk supply source for supplying milk to the nipple member above the nipple member, and supplies milk to the nipple member in a form close to natural fall from the milk supply source. By supplying, even a calf with a weak suction power was found to be able to sufficiently drink milk, and the present invention was completed.
[0011]
That is, the automatic feeding apparatus according to the present invention has a nipple member for causing the calf to suck milk, and a milk supply source for supplying milk to the nipple member, and the milk supply source is located higher than the nipple member. It is characterized by being arranged.
[0012]
In the automatic feeding apparatus of the present invention, the milk supply source is disposed at a higher position than the nipple member, and the milk from the milk supply source falls naturally onto the nipple member. Therefore, even when the suction force for sucking the nipple member is small, sufficient milk can be drunk from the nipple member.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the milk supply is located higher than the teat member. This milk supply source may be a mixer for preparing milk, or a tank or the like in which milk is sent from the mixer and temporarily stored. When a tank is used, the mixer and the tank can be connected via a pump or the like, and the milk can be transported to the tank. When a tank is used, a predetermined amount can be stored in the tank, so that the amount of milk supplied to the calf at one time can be accurately controlled.
[0014]
The height of the milk supply is preferably at least 120 cm (difference of height is at least 45 cm) since the height of the teat member is generally about 75 cm (at the height of the calf's mouth).
[0015]
An embodiment of the automatic feeding apparatus according to the present invention will be described with reference to the drawings.
FIG. 1 is an overall schematic diagram of the automatic feeding apparatus. In this figure, reference numeral 1 denotes a mixer for adjusting milk. The mixer 1 is connected to a tank 3 having a capacity of about 1 liter (a quantity to be fed to a calf at one time) by a liquid feed pipe 2 and is fed. In the middle of the liquid pipe 2, a pump 4 for pushing up the milk of the mixer 1 to the tank 3 is provided. Further, a nipple member 6 is connected to the tank 3 via a liquid feed pipe 5, and this nipple member 6 is fixed to a frame 7 installed on the ground. The tank 3 is arranged at a position higher than the height of the nipple member 6.
[0016]
In the automatic feeding apparatus as described above, when the calf a holds the nipple member 6 and sucks the milk, the milk falls from the tank 3 in a state close to the natural fall. Can drink milk.
[0017]
【Example】
[Example 1]
The automatic feeding apparatus shown in FIG. 1 was used. The height of the nipple member 6 was 75 cm, and the height of the tank 3 (the length from the ground to the bottom of the tank 3) was 120 cm.
[0018]
[Conventional example 1]
The conventional automatic feeding device shown in FIG. 2 was used. The same mixer and nipple member as in Example 1 were used.
[0019]
[Nursing test]
Ten suckling calves were allocated and a feeding test was performed for 14 days under the following conditions.
<Conditions per session>
Milk substitute: 125g
Hot water volume: 900cc
Feeding time: 120 seconds <conditions per day>
Feeding frequency: 4 feeding intervals: 2 hours
[Comparison contents]
The effects on calf nursing status (number of drinks, amount left over) and growth were compared.
[0021]
[result]
Table 1 shows the results of the nursing state.
[Table 1]
Figure 2004113170
Number of times: Total number of drinks-Maximum 40 times (4 times a day x 10 animals)
Quantity: the total amount of drink left in a day (liter)
[0022]
Table 2 shows the development results.
[Table 2]
Figure 2004113170
[0023]
From the above results, the number of feedings immediately after the start of automatic feeding was the same as in Example 1 and Conventional Example 1, and the frequency of calves coming to the feeding site was not affected by the difference in the method.
[0024]
However, as is evident from Table 1, in Example 1, the remaining amount was small, and it was only after the seventh day that all the heads could drink milk according to the feeding program. On the other hand, in the case of Conventional Example 1, it was on and after the eighth day that the remaining amount was large and all the heads could drink milk according to the feeding program.
[0025]
Moreover, as is clear from Table 2, the growth also reflects the result of the amount of the unreacted drink, and the example 1 greatly exceeds the conventional example 1 until 7 days after the start.
[0026]
As a result, in Conventional Example 1, it is considered that a calf unfamiliar with the nipple member or a calf having a weak suction force cannot fully drink milk immediately after the introduction, and as a result, the growth may be stagnated at the beginning of automatic feeding. is there. However, Example 1 does not require a large suction force because milk uses a height difference, and even a weak calf can sufficiently drink milk, thereby promoting healthy growth even at the beginning of automatic feeding. I was able to do it.
[0027]
【The invention's effect】
The present invention can sufficiently ingest milk even for young calves, small calves with weak suction power, and calves unfamiliar with nipple members, and as a result, promote healthy growth can do.
