The union of agricultural and animal husbandry to share with you about the black goat lamb soft para

In recent years in Henan, Anhui, Shandong, Hunan, Hubei, Hebei and Sichuan to produce a symptom to limp into the main features of the lamb disease, the disease incidence rate of nearly two years increased significantly, especially in the large scale black goat breeding sheep farm, households lamb incidence rate is high, serious mortality up to 40-60% range, causing great economic losses of sheep industry, it should be noted here is only to take treatment regimen in the treatment of hypoglycemia, 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 the aetiology, blood biochemical index determination, investigate the clinical symptoms and case anatomy, clinical treatment test and other aspects of research, to find out the reasons of the occurrence of the disease, the clinical symptoms and anatomic 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、本病多发生在上一年9月份以后怀孕，第二年二月份生的羔羊，母羊怀孕期间主要在冬季圈内饲养，怀孕母羊管理粗放、饲粮单一、营养缺乏、光照不足、运动量小，所生羔羊体质差， 是造成该病的主要原因之一。

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.

经调查山羊在规模养殖时，由于大部分养殖户按传统饲养管理方法，羊圈舍简陋，驱虫不到位，饲料单一，缺乏维生素、微量元素，特别是山羊必须的维生素A、D，微量元素碘、铜、硒等，能量、蛋白；钙、磷比例失调，造成母羊营养缺乏，乳汁内营养缺乏，影响羔羊的发育。特别是冬季羊群活动量小，阳光照射少，补饲跟不上，是冬春羔羊发病率高主要原因。本地所饲养的山羊属地方品种羔羊初生重较轻，需乳量小，经长期风土驯化对当地条件比较适应，而近年来由于进行波尔山羊杂交，初生羔羊体重增大，代谢快，随着杂交代次的增多羔羊体重的增加营养缺乏越来越明显。

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 comparison of adaptation to local conditions, and in recent years due to the hybridization of Boer goat, newborn lamb weight increase, fast metabolism and nutrition increased with hybrid generation times increased body weight of lamb's lack of more and more obvious.

2、羔羊的原因

Reason 2, lamb

由于羔羊生后1-15天内，胃功能不全胃、羔羊活动少、肠蠕动慢， 胃酶产生的少 乳汁在胃内消化慢停留时间长，造成消化不良，胎粪排出慢，胃肠道内稽留未消化的食物发酵造成自体中毒。这一系列原因造成羔羊发病， 解剖病死羊可见胃内有大量乳块 气味酸臭，肠道内容物呈黄色、白色、绿色，粪便有干、稀两种情况。

Since the 1-15 days after the 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, meconium discharge slow fermentation of food in the gastrointestinal tract, missed the undigested caused by self poisoning. This a series of causes of lamb disease, mortality of sheep stomach anatomy visible within a large number of milk block smell sour, intestinal contents of yellow, white, green, stool dry and thin in two cases.

3、羔羊的管理问题

3, the management problem of lamb

羔羊生后由于体温调节中枢不健全，外界温度对羔羊的影响很大，保温是管理羔羊的关键，另外外界温度高了羔羊喜欢活动，运动量大了有益于消化。

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.

临床症状

Clinical symptoms

新生羔羊3—15天内发病最多，绝大部分突然发病，发病早期体温正常或者稍高，主要表现为精神沉郁，前期呼吸加快、心率加快，后期心跳迟缓，反应迟钝， 黏膜苍白或者发绀， 发病时常发出尖叫声。而后，耳、鼻冰凉，四肢无力（见图片1、2），有时两前肢跪地或者两后肢拖地行走，吮乳困难，强力驱赶步态不稳，似醉酒样四处乱撞，继而表现为卧地不起，全身瘫软 ，腹部发胀（90%），不能吮乳。严重时病羊有空口咀嚼现象，眼球、肌肉震颤，角弓反张， 四肢挛缩，有的呈阵发性痉挛或前肢无目的的运动。或平躺着地，前期不见大小便或者大便干结，排便困难，后期大便失禁，60—80%发病羔羊排出黄色带粘液粪球或粘液性稀便。24-48小时后，体温下降至36℃以下或者不能测出体温，最后在昏迷中死亡。病程2--5天不等，早发现、早治疗一般绝大部分能迅速康复；救治不及时，到后期因羔羊不能吮乳，或者管理失当多数转归死亡 。

Neonatal lamb 3 - 15 days the highest incidence, the vast majority of sudden onset, 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, often when the incidence of screaming. Then, the ears, nose cold, limb weakness (see picture 1, 2), sometimes two or two hind forelimb knees mopping the floor walk, 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, late fecal incontinence, 60 - 80% the incidence of lamb with mucus discharge yellow ball of dung or mucoid stools. 24-48 hours after the temperature dropped to 36 degrees below 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.

解剖病变

对病死羔羊进行解剖可见肺脏水肿 、肺脏有出血点 ，肺部尖叶和心叶实变 ,心肌松弛，左右心室扩张，严重的心肌坏死呈灰白色，肝脏轻度肿大、色深有坏死点、脾脏出血坏死 ，肾脏水肿 ，死亡羔羊脱水明显 ，急性死亡羔羊可见胃内有大量未消化的乳凝块 ，胃内容物酸臭，中期胃内容物有乳凝块和混浊液体，胃内膜脱落，胃壁有条形出血，胃壁变薄 ，后期胃内容物水样或者空虚，胃壁菲薄呈空气球样 ，部分病死羔羊小肠粘膜出血，大肠及直肠内有黄色或灰白色球型或乳状粘液性物。个别羔羊肋骨柔软可弯曲成U型。

临床治疗试验

为了探索对该病的有效防治方案我们通过近三年的努力主要采用以下防疗方案：

A、对母羊群实行定期驱虫，饲喂全价饲料，冬季增加运动量、增加日照时间，羔羊在生后每只补乳100毫升，新生羔羊发病率由原来的80%以上减少到10%左右。

B、发病羔羊治疗方案如下，其结果见表2

1、补糖法：静脉注射10—25%葡萄糖+VC+庆大霉素。

2、补糖补钙法：静脉注射10—25%葡萄糖+葡萄糖酸钙+庆大霉素。

3、胰高血糖素法：肌注、皮下注射或静注注射胰高血糖素每次0.5mg～1.0mg。

4、口服葡萄糖+葡萄糖酸钙法；每只羔羊口服葡萄糖、葡萄糖酸钙各10克。

表2临床治疗统计表

以上治疗试验证明：单纯补糖临床治愈率在60%左右，对发病早期效果明显，中后期效果欠佳。补糖补钙法效果较好但需要静脉工作量大。胰高血糖素法起效果较快但停药后易反复，口服口服葡萄糖+葡萄糖酸钙法，本方法起效慢一般12小时以后见效果，对严重病例不能起到急救效果。
