Abstract

ABSTRACT Sow litter sizes have increased recently, and there is a lack of data on the effect of litter size on sow health and sow medical treatment. This study investigated associations between litter size and medical treatment of sows, using data for a 10-year period from one Swedish research farm. The data comprised 1947 litters from 655 Yorkshire sows. Association between litter size and medical treatment of sows during farrowing and lactation investigated using a multivariable multilevel logistic regression model. We found that odds of medical treatment of sows decreased for each additional piglet born up to five piglets (odds ratio 0.50, p = .002). For litter sizes ≥5, the odds for each additional piglet born (odds ratio 1.11, p < .001). Problems with milk let-down in early lactation were the main reason for treatment. Results imply that sows with very small or very large litters may be less profitable.

产仔数与母猪在分娩和哺乳期间的医疗之间的关系

摘要近年来母猪产仔数有所增加，但产仔数对母猪健康和母猪医疗的影响缺乏相关数据。本研究调查了产仔数与母猪医疗之间的关系，使用了瑞典一家研究农场10年的数据。数据包括655头约克郡母猪的1947窝。利用多变量多水平logistic回归模型研究了母猪产仔数与分娩和哺乳期间药物治疗的关系。我们发现，每增加一头仔猪(最多5头仔猪)，母猪接受药物治疗的几率就会降低(优势比0.50,p = 0.002)。当产仔数≥5时，每增加1头仔猪出生的几率(优势比1.11,p < 0.001)。哺乳期早期漏乳问题是治疗的主要原因。结果表明，产仔量非常小或非常大的母猪可能利润较低。
