Hairy Attack Details 👇
Hairy attack is a type of intractable, contagious horseshoe disease in cattle that is characterized by more severe and widespread lesions than Digital Dermatitis (DD, also known as athlete s foot in cattle or strawberry dermatitis).
Symptoms
Cows suffering from hairy attacks often experience strong pain in the lesion and lameness (limping, difficulty walking). The main symptoms are:
Appearance of the lesion: It appears as a light grayish-brown area with tangled and matted hairs on the surface. This may also look like a "strawberry."
Occurrence site: It is mainly found between the hoofs (between the hoofs) near the hoofs, but it may also occur near the front crown (the top of the hoof).
Physiological Effects: Due to severe pain, the cow's feeding and milk yield are significantly reduced, which can also adversely affect breeding.
Cause
Hairy attack is a disease caused by bacterial infection and is partly due to an unsanitary feeding environment.
Main Causative Bacteria: It is thought that anaerobic spirochete bacteria known as Treponema are mainly involved.
Possible Multi-Bacterial Infection: Diverse bacterial populations are present in the lesion, suggesting that it may be a strong multi-bacterial infection.
Environmental factors: Hygienic environmental management such as frequent discharge of manure, drying of cattle beds and aisles, and appropriate ventilation is essential for prevention.
Treatment and Prevention
In the absence of effective preventive and / or therapeutic measures, countermeasures are often difficult.
Treatment:
Generally, after cleaning the affected area, external medicine such as mastitis ointment is applied and bandages are wrapped.
If the lesion is severe, it may be necessary to remove dead skin from the dermis of the hoof, similar to the sole ulcer.
It is being studied that certain chemicals, such as allyl isothiocyanate, may be effective in preventing and treating.
Prevention:
Horseshoes: A hoof tub is installed at the entrance of the barn or paddock, and regular hoof bathing with copper sulfate solution is effective.
Environmental Improvement: It is important to keep the cattle beds and aisles dry and to eliminate mud.
Regular hoofing: Regular hoofing (hoofing) at least twice a year can also help prevent it.
検索で「水虫 趾間型 画像」を見てから牛の蹄を見た時、最初は“趾間が赤くただれてる＝同じような皮膚炎かな？”と感じる人も多いと思います。私も最初は、人の水虫（趾間型）みたいに“白くふやける・皮がめくれる”イメージで探してしまって、見逃しそうになったことがあります。でもヘアリーアタック（趾皮膚炎/DD系）は、見た目のポイントが少し違います。 私が現場でまず見るのは「場所」と「痛がり方」です。趾間（蹄と蹄の間）〜蹄踵のあたりに、赤〜灰褐色で湿った病変があって、触る前から脚を引く・蹴る・体重を乗せないようにする個体は要注意。表面が“いちご状”に見えたり、毛が絡んでマット状になっていると、いわゆるヘアリーアタックっぽさが強いです。人の趾間型水虫の画像でよく見る「白くふやけた皮膚」「皮むけ」とは質感が違って、牛の場合は“ジュクッとして痛みが強い”印象が先に来ます。 処置の流れで大事だと感じるのは、薬を塗る前の下準備です。 ・泥や糞尿の付着をしっかり落とす（洗浄不足だと薬が効きにくい） ・浮いた角質や汚れで覆われているところは、無理のない範囲で除去して病変面を見える状態にする ・その後に外用薬（乳房炎軟膏などを使う現場も多い）→包帯 包帯は「締めすぎない」「でも緩すぎてすぐ脱げない」バランスが難しいので、巻き終わりの固定の仕方を毎回工夫しています。濡れたまま巻くと蒸れて悪化しやすいので、拭き取りも意識しています。 再発・蔓延を止めるには、処置と同じくらい環境が効きます。通路の湿り、牛床の濡れ、換気の悪さが続くと、治しても追いつかないことが多いです。私の経験だと、糞尿の滞留が減って床が乾くだけで、新規の発生が目に見えて落ちることがあります。 最後に、蹄浴は“やるなら継続”が前提だと思っています。出入口に導線を作って定期的に通すと、牛の蹄病（DD系）の波がなだらかになります。削蹄も形を整えるだけじゃなく、異常の早期発見につながるので、年2回以上の定期チェックはやっぱり強いです。part2として、見た目の判断→処置→再発対策まで、少しでも現場の手がかりになれば嬉しいです。
