When there are too many or large stones in the bladder and urethra of sheep, symptoms will appear, and urination will be partially or completely blocked. After the occurrence of urinary calculi in sheep, the early sick sheep showed pain and anxiety, and often made a hunchback urination posture. The hind legs extended to both sides and urinated frequently, but it was difficult to urinate. Sometimes the dripping urine can only excrete a few drops, or the urine drops are mixed with blood, and in severe cases, it is impossible to urinate at all. If not treated in time, the bladder will swell due to a large amount of urinary retention in the later stage, and it will be difficult to urinate under pressure, which may lead to bladder rupture; Sheep suffer from depression, hypothermia, salivation in the mouth, muscle tremor, deep and slow breathing, weak and fast pulse, systemic subcutaneous edema, uremia-like symptoms, and often die within 4~5 days.

Prevention and cure method

1, prevention

Feed must be reasonably matched. Do not feed a single feed for a long time. Feed more green and juicy feed. Rinse with clear water before feeding to reduce its silicon content. Mix some green hay in winter, feed some carrots and beans in spring, and fully supply clean drinking water. Change land for grazing and increase activities.

Step 2 deal with

Simple drug treatment is generally ineffective, and surgical stone removal is expected to be cured.

surgical treatment

First, carefully move the stone with a urethral probe and take it out. If this method is difficult to achieve curative effect, urethrotomy can be performed: the sick sheep lies on its back in Baoding, and after the operator finds out the position of the stone, he makes a 7 cm long longitudinal incision above the midline slightly in front of the stone, and then passively separates the loose tissue around the ventral side of the penis; After the penis is completely exposed, touch the position of urethral calculus with your fingers and make a slight incision above the calculus. The size of the incision is subject to the stone, generally about1cm; The incision position must be in the midline, otherwise it will cut into the cavernous body on both sides of the penis, causing bleeding.

The surgeon pinches the stone with his thumb and forefinger, squeezes the stone along the incision, takes out the stone and excretes urine. After that, the internal and external incisions need not be sutured, but the incisions must be cleaned and disinfected every day to facilitate healing. Catheter tools should be soft and smooth, especially the head, and should be coated with paraffin or vaseline lubricating oil. In order to prevent infection, diuretics, urethral disinfectants, gentamicin and other antibiotics should be used properly after lithotomy. The dosage should be 1 1,000 ~11,500 iu per kg body weight, or 5~ 10mg tetracycline per kg body weight. You can also use 20% sulfadiazine sodium injection 5 ~ 65438±00ml, intramuscular injection twice a day for 3~5 days. At the same time, give more water.

Treatment of bladder rupture

When rectal examination can't distinguish bladder morphology and only floating small intestine and mesentery are found in abdominal urine, bladder intubation and bladder suture can be used for treatment.
