Release time:
2018-10-09
Sheep intussusception refers to the phenomenon that a certain segment of intestine and mesentery are inserted into another continuous segment of intestine at the same time, resulting in the overlap of double intestinal wall. Both male and female sheep can develop the disease, but the ewe is more likely to occur. As long as the onset of the disease, the application of drugs can only alleviate the symptoms, must take surgery to correct. At present, there is no specific treatment for the disease, and prevention must be strengthened. Etiological analysis and prevention of sheep intussusception.
sheep intussusceptionRefers to a section of intestine and mesentery at the same time into another continuous section of intestine,This results in the overlap of the double intestinal wall. Both male and female sheep can develop the disease.,But one of the ewes is more likely to occur. As long as there is an onset,Application of drugs can only relieve symptoms,Surgery must be performed to correct it. Currently,There is no specific treatment for the disease.,Prevention must be strengthened. Etiological analysis and prevention of sheep intussusception.
1Etiological analysis
In the process of sheep feeding, intussusception disease can occur in any season of the year, which is easy3～5Months and9～11month of onset. In particular, grazing flocks are very prone to the disease at this stage, while intensive farms are less likely to occur. The etiology of sheep intussusception is more complex; mainly in the following aspects.
Improper feeding and management.
The flock is suddenly and severely frightened and continues to jump during the scurry, which can easily lead to intussusception. In winter, eating irritating feed or cold forage causes severe irritation of the intestinal wall, which causes spasmodic contraction and peristalsis of the intestine, which in turn causes intussusception. In addition, rams with each other's horns, or grazers kick and beat the abdomen, etc., will damage the abdomen due to excessive external impact, resulting in intussusception. In addition, the sheep in the shearing due to hard struggle or sudden flip, is also an important cause of the disease.
Suffering from disease.
Sheep intestinal lesions, such as enteritis, intestinal nerve disorders, intestinal vasospasm, etc., will lead to spastic contraction of the intestine, thus inducing intussusception. In addition, intestinal parasites can also cause the disease, especially nodular parasites, which can form hard nodules on the intestinal wall and directly lead to normal intestinal tract. The regular movement is disturbed, and due to the influence of the nodule, the local intestinal tube can not be restored to its original state, which will cause intussusception intestinal obstruction plug, and with its continuous feeding and exercise, the previous intestinal tube continues to enter the intestinal lumen, which makes the intussusception more serious and the symptoms obviously aggravate.
Other factors.
Ewes during pregnancy or childbirth, due to fetal pressure or did not take reasonable midwifery, can also lead to intussusception. Lambs sucking on thick or spoiled breast milk can cause indigestion or spasmodic contraction of the intestines due to overdrinking, which can also cause intussusception.
2Clinical symptoms
The sick sheep showed obvious abdominal pain, frequently looked back at the abdomen, and constantly twisted the waist, stretched the waist, kicked the abdomen with the hind limbs, stood up and lay uneasily, even rolled continuously after lying on the ground, the nasal mirror trembled, and the upper lip cocked, which was very painful. Appetite waste, stop ruminating, but thirst increases. The nasal endoscope is dry, the nasal fluid flows out, the frequent blame, showed defecation action, urination frequency increases, but urine volume decreases. The body temperature is basically normal, the heartbeat is accelerated, the rhythm is abnormal, the heart sound is hyperfunction, the respiration is accelerated, the gastrointestinal peristalsis is irregular, the intestinal sound is weakened, the abdominal circumference is obviously increased, the pressure palpation abdominal reaction is sensitive. In the late stage of the disease, the degree of abdominal pain of the sick sheep is relieved. They often stand alone, and their limbs are open. Sometimes they stretch their waist, often lying on the ground, and kick their abdomen with a hind limb, forcing them to stand up, and the phenomenon of stretching and uneasiness will appear.
3Key points of diagnosis
The disease can be preliminarily diagnosed according to the etiology and clinical symptoms. If a definite diagnosis is required, the abdomen should be palpated for further examination. Even if the sick sheep lies on the left side, the right hind limb should be straightened with the left hand to Baoding, and then the right hand should be used to touch and press the left side and lower abdominal wall one by one. If the skin and muscle have tremor tenderness reflex, the diagnosis can be confirmed.
4Prevention and control methods
Non-surgical treatment.
Sick sheep in the earliest stage of disease that is after the disease3hIt is appropriate to take this method for treatment, which is due to the short time of intussusception at this time, only a small part of the intussusception, and no adhesion of the intestinal tube, it may be easier to pull the intestinal tube and reset it. Operation method: first make the sick sheep in the posture of limbs facing up, and then use two fists to press and massage the abdomen rhythmically with appropriate strength. Push and squeeze several times in the order of front to back, back to front, top to bottom, bottom to top, left to right, and right to left. The obvious pain is the place where intussusception occurs. When a sick sheep stands, his hands are placed on the left and right sides of the abdomen to push and squeeze in the order from front to back and from back to front to make it appear violent and short-term movement. For example, after grasping one of the hind limbs, he will struggle hard and jump, which can promote intestinal restoration.
surgical treatment
After anesthesia, the sick sheep was placed on the operating table on the left side, and the left side was cut and disinfected. Vertical incision of skin10cm~15Cm, after cutting the skin, make pure separation according to the direction of muscle fiber, lift the peritoneum, and carefully cut the intestinal canal injured by mistake. The surgeon extends his hand into the abdominal cavity along the incision. If he can touch the sausage-like hard block, the intussusception part will be painful when pressing, and gently pull it out of the abdominal cavity. If the color does not change, the organization has vitality, can be used to gently squeeze the stretching hand can be adjusted. If tissue death occurs, resection and intestinal anastomosis must be performed. regular close the abdominal cavity.
