In recent years in Henan, Anhui, Shandong, Hunan, Hubei, Hebei, Sichuan and other places in a limp symptoms as the main characteristics of the lamb disease, the disease incidence rate increased significantly in recent two years, especially in the large scale sheep farm, a higher incidence in the lamb household, serious mortality rates up to 40-60% unequal, causing great economic losses of sheep industry, it should be noted here is only to take treatment regimen in the treatment of low blood sugar, the effect is not very obvious. In order to find out the causes of the disease, we conducted an extensive survey of the incidence, occurrence regularity, and from the etiology, clinical symptoms, blood biochemical index determination of investigation, case anatomy, clinical treatment test and other aspects of research, to find out the reasons of the occurrence of the disease, the clinical symptoms, anatomical lesions were statistical analysis, very satisfactory results achieved through a large number of prevention and treatment of test, report as follows now, for reference. Cause of disease:

1, the disease occurs in September last year after pregnancy, born in February second ewe lamb, mainly feeding on Dongjiquan during pregnancy in pregnant ewes, extensive management, single, lack of nutrition diet, insufficient light, a small amount of exercise, lamb born poor health, is one of the main causes of the disease.

After the investigation of goats in the scale of farming, as most farmers in the traditional feeding and management methods, sheep shed simple, insecticide is not in place, single feed, lack of vitamins, trace elements, especially the goat must vitamin A, D, trace elements of iodine, copper, selenium, energy, protein, calcium and phosphorus imbalance,; cause the ewes of nutritional deficiencies, lack of nutrition milk, influence the development of lamb. Especially in winter flocks of the activities of a small amount, less sunlight, supplementation does not follow to go up, the main reason is the high incidence of winter and spring lamb. The local goats reared is a local breed lamb birth weight is light, need a small amount of milk, after long-term acclimatization compared to adapt to local conditions, and in recent years due to the hybridization of Boer goat, newborn lamb weight increase, fast metabolism, nutrition increases the hybrid generation with increasing body weight of lamb's lack of more and more obvious.

Reason 2, lamb.

Since the 1-15 days after birth in lamb, gastric dysfunction of stomach, lamb activity less, slow peristalsis, less milk stomach enzymes produced in the stomach digest slowly to stay for a long time, cause indigestion, fecal excretion is slow, the fermentation of food in the gastrointestinal tract of missed undigested caused by self poisoning. This a series of causes of lamb incidence, fatality sheep stomach anatomy visible within a large number of smell sour milk block, intestinal contents of yellow, white, green, feces dry, thin two cases.

3, the management problem of lamb

Lamb after birth because of the central temperature regulation is not perfect, great influence of external temperature on lamb, insulation is the key management of the lamb, in addition the outside temperature high lamb like activity, big amount of exercise is good for digestion.

Clinical symptoms

Neonatal lamb 3 - 15 days the highest incidence, the vast majority of sudden onset, black goats with early onset temperature is normal or slightly higher, mainly for depression, the early rapid breathing, heart rate, heart beat slow late, slow reaction, pale mucous membranes or cyanosis, when the disease often send out scream. Then, ear, nose cold, limb weakness (see picture 1, 2), sometimes two or two hind forelimb knees mopping the floor walking, suckling difficulties, strong drive instability of gait, like a drunk like rattling around, and then for the performance of recumbency, dejection, swollen abdomen (90%), not to suck the breast. Serious disease of sheep have empty chewing phenomenon, eye, muscle tremors, opisthotonus, limb contractures, some paroxysmal spasm or forelimb purposeless movement. Or lying flat, early not to see the toilet or dry stool, defecation difficulties later, fecal incontinence, 60 - 80% the incidence of lamb with mucus discharge yellow ball of dung or mucoid stools. After 24-48 hours, the drop in body temperature to 36 DEG C or not measured temperature, finally died in a coma. The course of 2--5 days, early discovery, early treatment is generally most can recover rapidly; the treatment is not timely, to the late because not sucking lamb, or mismanagement most outcome of death.

Anatomical lesions

The mortality of lamb were dissected visible edema of lung, lung hemorrhage, pulmonary pointed leaves and leaf consolidation, myocardial relaxation, left ventricular dilatation, severe myocardial necrosis was gray, mild hepatic enlargement, color deep necrosis, hemorrhage and necrosis of the kidney spleen point, edema, dehydration obvious acute death death lamb, lamb visible gastric there are a large number of undigested curd, contents of stomach sour, mid stomach contents has milk clotting and turbid liquid, the stomach lining the stomach wall with strip off, bleeding, gastric wall thinning, later period stomach contents or empty stomach in water samples, thin air ball like, partial mortality lamb intestinal mucosa bleeding, colon and rectum there are yellow or gray chromosphere type or emulsion mucinous substance. Individual lamb ribs soft can be bent into type U.

Clinical treatment test

In order to explore the effective prevention and cure of the disease of our scheme through effort of nearly three years following anti therapy:

A, the sheep flock of Montenegro implement regular deworming, feeding the full price of feed, increase the amount of exercise, increase the winter sunshine time, lamb after birth each fill the milk 100 ml, the incidence of neonatal lamb from 80% reduced to about 10%.

The following B, the incidence of lamb treatment, the results in Table 2

1, glucose feeding method: intravenous injection
