Claw lesion is one of the major causes of lameness in sows and the lameness is one of the reasons for culling of sows from the swine herd. This survey was conducted on sows in total of 8 farms with a total of 684 pigs. The lesions observed in the study were horizontal and vertical claw cracks (CWH &...

모돈 파행의 원인이 되는 요인들은? | 모돈 파행의 원인이 되는 요인들은 유전적인 요인 (Anil 등, 2005; Anil 등, 2006), 돈사 구조(Svendsen 등,1992), 후보돈 선발과 육성(Koketsu, 2000), 사료급여 (Bryant 등, 1985) 등이 있다. 발굽 병변 또한 파행의 중요한 요인이 된다(Penny 등, 1963; Dewey 등, 1993; Anil 등, 2009; Pluym 등, 2013; Ala-Kurikka 등, 2017). | |
발굽 병변의 원인은? | 발굽 병변 때문에 생긴 파행으로 도태되는 모돈의 수를 최소화하기 위해, 발굽 병변과 파행 사이의 연관성에 대한 이해가 매우 중요하다. 발굽 병변의 원인이 되는 요인들은 세균과 바이러스 등의 병원체 감염, 환경, 영양 그리고 유전적 요인이 포함 될 수 있다(Rowles, 2001). 이중 전염성 질병에 의한 파행의 원인은 브루셀라병, 돈단독, 구제역, 부제병, 글래서씨병, 살모넬 라증, 돼지수포병 그리고 연쇄상구균 감염 등이 있고, 후보돈 또는 초임신돈에서 전염성 파행의 원인은 돈 단독, 글래서씨병 등과 밀접한 관련이 있다. | |
발굽 병변으로 생긴 파행이 미치는 부정적인 영향은 무엇이 있는가? | 파행(Lameness)은 모돈의 도태를 포함하여 폐사 또는 안락사로 이어지는 주요 원인이 되며(Stone, 1981; Friendship 등, 1986; Jørgensen, 2003), 그로 인해 많은 농가에서 경제적인 손실이 발생하고 있다(Dagorn과 Aumaitre, 1979; Anil 등, 2008). 6∼35%의 모돈은 파행으로 인해 도태된다(Hill, 1992; Boyle 등, 1998). |
