Skin Wounds in Livestock: Causes, First Aid, and Management

Skin wounds in livestock may be caused by contact with sharp objects, unsuitable equipment, fighting among animals, prolonged recumbency, burns, insect bites, or skin diseases.

The severity of a wound does not depend only on its outward size. Small but deep, contaminated wounds, or those near a joint, eye, udder, or hoof, may require prompt veterinary evaluation.

The most important causes of wounds

• Sharp edges of feed troughs, doors, and fences
• Wire, nails, and metal parts
• Goring or fighting between animals
• Slipping and falling
• Continuous pressure in recumbent (down) animals
• Improper injection
• Itching caused by external parasites
• Chemical or thermal burns
• Injury to the udder and teat
• Insect bites and infestation of the wound with fly larvae

Correcting the cause of the wound is very important, because if a sharp edge, unsuitable bedding, or the cause of itching remains, the injury will recur.

How should we assess a livestock wound?

In the initial assessment, the following should be evaluated:

• Location and depth of the wound
• Amount of bleeding
• Presence of mud, manure, or a foreign object
• Swelling, warmth, and pain
• Purulent discharge or unpleasant odor
• Presence of black, dead tissue
• The animal's ability to move
• Fever, lethargy, or reduced appetite

Puncture wounds may appear small on the surface, yet carry contamination into deeper layers and set the stage for abscess formation.

First aid for superficial wounds

• Keep the animal in a clean, dry place.
• If bleeding, apply direct pressure with gauze or a clean cloth.
• Clean around the wound without causing further injury.
• Remove surface contamination with wash saline or clean water.
• Prevent manure, soil, and insects from re-entering the wound.
• Check the wound daily for swelling, discharge, and change in odor.

Proper washing helps remove contamination and reduce the microbial load. The type of dressing, suturing, or removal of dead tissue should be determined by the veterinarian based on the location and condition of the wound.

What should be avoided?

• Using caustic and concentrated substances on the wound
• Pouring powder or contaminated compounds onto the injury site
• Closing a deep, contaminated wound without assessment
• Arbitrary use of antibiotics
• Pulling out deep tissue or a foreign object
• Leaving the injured animal on wet, contaminated bedding

Some wounds should not be closed immediately, because contamination and damaged tissue remaining under the skin can increase the likelihood of infection.

When should you contact a veterinarian?

• Bleeding does not stop with direct pressure.
• The wound is deep, extensive, or penetrating.
• A joint, tendon, eye, udder, or teat is involved.
• The animal has severe lameness or is unable to move.
• Purulent discharge, a foul odor, or dead tissue is seen.
• There is fever, lethargy, or reduced appetite.
• Insect larvae are observed in the wound.
• The wound does not heal after several days.

The presence of fly larvae in a wound requires prompt action, because some larvae can feed on living tissue and spread the injury.

Preventing skin wounds

• Remove sharp edges and metal parts from the housing.
• Correct slippery floors and wet bedding.
• Reduce crowding and fighting among animals.
• Keep recumbent animals on soft bedding and reposition them regularly.
• Implement a control program for ticks, lice, and mange.
• Train staff in the correct method of injection and animal handling.
• Check small wounds before contamination spreads.

Regular repositioning of a recumbent animal, soft bedding, a clean environment, and proper nutrition are important in preventing pressure wounds.

Frequently asked questions

Does every wound need an antibiotic?

No. The need for an antibiotic depends on the depth, contamination, and location of the wound and the presence of a general infection, and it should be determined by the veterinarian.

Can the wound be washed with water?

To remove surface contamination, clean water or wash saline can be used. Deep wounds or those near sensitive structures should be examined by the veterinarian.

Should a livestock wound always be dressed?

No. Whether dressing is possible depends on the location of the wound, the degree of contamination, and the animal's housing conditions.

What sign suggests the possibility of infection?

Increased swelling, warmth, pain, purulent discharge, unpleasant odor, fever, and reduced appetite can be signs of infection.

Summary

Managing a skin wound in livestock begins with stopping the bleeding, proper washing, preventing re-contamination, and assessing the depth of the injury. Deep, contaminated wounds, or those near sensitive structures, should not be treated without veterinary evaluation.
