1.1 Moldy Feed
During the summer, high temperatures and humidity, combined with prolonged exposure of feed to air or sunlight, can cause unsaturated fatty acids in the feed to react with oxygen. This produces aldehydes and copper compounds, resulting in mold growth and feed deterioration.
1.2 Weak Constitution
Long-term feeding of moldy feed or a lack of variety in the diet leads to deficiencies in essential vitamins, weakening the livestock's overall health.
First, eliminate the underlying causes. Stop feeding the old feed and switch to a balanced, high-quality feed.
2.1 Closed Treatment
Clean the affected area with 0.9% saline solution. If the mucosa is necrotic, trim it with scissors.
Rinse the prolapsed area with cold saline (to constrict capillaries and prevent bleeding).
Apply a lubricant and reposition the prolapsed anus. Then, inject a mixture of 75% alcohol and 25% procaine (in equal amounts) around 1-2 cm from the anus, injecting 1-2 ml at each of 4 points (top, bottom, left, and right), parallel to the rectum, 0.5-2 cm deep.
This procedure usually heals the condition after one injection.
2.2 Surgical Treatment
For severe cases, control feed intake and use laxatives (e.g., magnesium sulfate, artificial salt) to empty the intestines.
During surgery:
Clean the skin around the anus and tail with soapy water and disinfect with a 0.1% potassium permanganate solution or 2%-5% alum solution.
Squeeze out the edematous fluid, apply erythromycin ointment or penicillin powder, and place sterile gauze soaked in saline on the area.
Reposition the prolapsed anus, then perform either purse-string or cross sutures, ensuring the tension is appropriate: too tight can affect defecation, too loose can cause re-prolapse.
Administer penicillin or streptomycin intramuscularly twice daily for 3 days (30,000-40,000 units per kg body weight).
Add 0.1% chloramphenicol to the feed for antibacterial and anti-inflammatory effects.
Control feed intake for 1-2 days, while supplementing with vitamin C to boost nutrition and stress resistance.
Provide liquid or fresh, juicy green feed.
Ensure proper disinfection, hygiene, dryness, and warmth in the livestock's shelter.
