母猪肢蹄病的研究进展 总被引:3,自引:0,他引:3
母猪肢蹄病是母猪四肢和四蹄疾病的总称,它包括变形蹄、变形肢、遗传性肢蹄病、传染性肢蹄病和非传染性肢蹄病等类型。变形蹄有过长蹄、过宽蹄、卷蹄、卧系低蹄、突系高蹄、外蹉蹄、蹄裂、蹄底增生等几种;变形肢有“X”状肢、“()”状肢等几种;遗传性肢蹄病有外翻腿(撇拉腿,长白和约克夏品种较多)、前肢增粗、屈曲腿、内趾过小、独趾(马蹄样)、多趾、蹄裂、蹄底增生、“X”状肢、“O”状肢等几种;传染性肢蹄病有口蹄疫、链球菌病、葡萄球菌病等几种;非传染性肢蹄病有变形蹄、变形肢、软组织伤、骨骼伤、神经性肌肉麻痹症、化脓性炎症、风湿性关节炎、瘫痪等几种。 相似文献

母猪肢蹄病的调查研究 总被引:7,自引:0,他引:7
对湖南18个中小型养场的2083头,母猪进行了肢蹄病调查,调查结果表明:患有肢蹄病的母猪750头,发病率36%,且发病率随母猪年龄、胎次的增加而上升。并与栏舍地面结构十分相关;如漏网式地板母猪肢蹄病发生率为28%,而水泥地板发病率则为37.3%。简易节能型畜床使肢蹄病发病率下降70%~80%。 相似文献

肢蹄病是母猪被淘汰的主因 总被引:1,自引:0,他引:1
肢蹄病是母猪被淘汰的主因苏堰,吴顺聪(广东省农科院畜牧研究所广州510640)提高母猪繁殖力,减少母猪非正常淘汰是养猪界和兽医工作者极为重视的课题。查清集约化肉猪生产线中母猪淘汰的主因和诱因,就可采取针对性综合措施,充分利用母猪繁殖能力,获取更多健康... 相似文献

肢蹄病是影响奶牛业发展的主要疫病之一,在规模化养殖场,肢蹄健康是奶牛高产和健壮的重要保障.该病发病率30%~40%,病症为行走困难,运动跛行,产奶量下降,病牛很快消瘦,会给奶牛养殖业带来很大的损失. 相似文献

种母猪肢蹄病是常见的疾病之一,该病的发生与种质、营养、环境卫生及病原微生物等多种因素有着直接的关系.虽然肢蹄病一般不具有传染性,但其在猪场的发生率却很高,一般为5%-10%,再加上该病治愈率较低,往往导致母猪过早淘汰,给养猪企业造成巨大的经济损失. 相似文献

During a 12-month period lameness, claw lesions and claw infections were studied in 15 herds with loose housing of pregnant sows on partly slatted concrete floors. Of these herds, 12 herds had concrete slats and 3 herds had plastic slats. The mean prevalence proportion of lame sows in the herds was 13.1%. The risk of lameness increased with increasing claw lesion score and with the presence of claw infections. In the herds with concrete slats, the relative risk of lame sows was 2.4 times higher than in the herds with plastic slats. In the herds with poor floor hygiene, the relative risk of lameness was 2.8 times higher than in the herds with dry and clean floors. The mean prevalence proportion of sows with claw infections at the 3 separate examinations in the 15 herds was 3.8%. Claw infections were more prevalent in herds with dirty floors and in herds with little space per animal (<2m2). In the herds with concrete slats, the relative risk of claw infections was 2 times higher than in the herds with plastic slats. 相似文献

A three-week-old warmblood colt was referred for a two-week history of lameness on the left thoracic limb, and a two-month-old Quarter Horse–mix filly was referred for malaligned pelvic limbs since birth. The foals were diagnosed with agenesis and dysgenesis of the navicular bone, respectively. In this report, we present clinical signs, diagnostics, and postmortem workup of the two cases. 相似文献
