My cow had milking blood sores (blacks themselves, and a blood hole in the middle). Milking is all swollen, inside the bumps. The cow does not give at all to milk. Tell me, please, what is it and how to treat it? (Olga)
What it is?
Unfortunately, the sores you described strongly resemble smallpox. In cows (females), it most often manifests itself primarily on the udder. Treatment must begin immediately, otherwise things will be bad. Also, do not be amiss to show these "acne" to the vet. Let him inspect and take tests (perhaps enough inspection).
How is it treated?
Treatment of smallpox is quite versatile and some antibiotics will be small. The first thing to do is to transfer the animal into a dry and warm room. Keep your litter clean and dry. Now you need to pay attention to feeding. It must be sufficiently nutritious, and if necessary it is necessary to feed with semi-liquid mixtures.
Also need to milk daily. If the cow does not allow it to be done manually, then a milk catheter can be used. The main treatment is with antibiotics, cauterizing ulcers, weak antiseptics and ointments that soften the skin (boric, petroleum jelly or zinc). The nasal cavity of the patient must be periodically treated with a solution of boric acid of 2-3%.
Pimples and ulcers burn with 3% chloramine, tincture of iodine or Boer fluid. After reducing acne, the above skin softening ointments are used. If our diagnosis is correct, then treatment should begin immediately.
