| 仔猪咬尾症是仔猪常见的异食癖，常由于营养机能紊乱及饲养管理不当导致的该应激反应发生。常见于仔猪12~14周龄，在每年1-3月份及8-12月份发病率较高，母仔猪较公仔猪发病率高。其特征症状是咬尾仔猪的行动敏捷，被咬仔猪一阵尖叫挣扎，猪尾断节，鲜血淋漓。轻者猪尾被咬掉半截，重者全部被咬掉。被咬仔猪，因失血而发生贫血，生长发育受阻，个别仔猪因失血过多而死亡。如果没有及时处理并采取治疗措施，会导致伤口发生感染，引发局部发炎和组织脓肿、坏死，使肉质下降、减产。文章通过分析仔猪咬尾症的症状、发病原因，并根据病因提出应对的防治措施。阐释仔猪咬尾症在养殖生产过程中的危害及在现代化养殖中如何科学合理地避免因咬尾造成的经济损失。 |
| 英文摘要: |
| Piglet tail-biting syndrome is a common pica in piglets, which often occurs due to nutritional disorders and improper feeding and management. Between 12 and 14 weeks of age in piglets, this syndrome is common, and the incidence rate is higher in January-March and August-December each year. Comparatively, female piglets have a higher incidence rate than male piglets. From a clinical point of view, the characteristic symptom is that the piglet biting others is quick to move, in contrast, the bitten piglet screams and struggles, and the tail is broken and bloody. The tails of the slightly injured piglets are bitten off in half, and the tails of the heavily injured piglets are all bitten off. Bitten piglets have anemia problem due to blood loss and their growth and development are hindered. Even individual piglets die due to excessive blood loss. If the treatment is not done or treatment measures are not taken in time, the wound will become infected, causing local infl ammation, tissue abscesses, and necrosis, resulting in decreased meat quality and reduced production. In summary, the article analyzes the symptoms and causes of piglet tail-biting, and proposes countermeasures based on the causes, what's more, it explains the hazards of piglet tail biting syndrome in the breeding process and how to scientifi cally and reasonably avoid the economic loss in modern breeding. |
