Abstract In modern pig production up to 50% of the sows are slaughtered each year. Typically, the period from the decision to cull and until a sow is slaughtered consists of a stay in an on-farm pick-up pen (hours to weeks), transport (eventually passing buying stations or similar) and lairage. However, even though cull sows are often mentioned as vulnerable toward challenges such as transport, the behaviour and welfare of these animals have received very limited scientific attention. The aim of this study was to examine clinical and behavioural consequences of keeping cull sows in on-farm pick-up pens before transport to slaughter. The observational study took place in a private Danish sow herd with loose-housed gestating and lactating sows. The study included 103 sows with a mean parity of 5 (range 1–9) and a BCS of 3 (range 2–3). On the day of weaning, the sows were examined clinically, and walked to pick-up pens in another part of the same building, each pen holding 3–4 sows. In the pens, the sows had free access to water from a water cup and were fed on the floor twice a day with a total 2.5 FU per sow. The mean room temperature was 21.0 °C (range 18–25.6 °C). After 24 h in the pick-up pens, the clinical condition of the sows showed signs of deterioration, as judged by an increased number of superficial skin lesions (median 0 (range 0−22) v. a median of 9 (range 0−75); P

断奶后淘汰母猪在农场混合的临床和行为后果

摘要 在现代养猪业中,每年有高达 50% 的母猪被屠宰。通常情况下,从决定淘汰到母猪被屠宰的这段时间包括在农场的收集栏(数小时到数周)、运输(最终经过采购站或类似场所)和猪栏。然而,尽管经常提到淘汰母猪容易受到运输等挑战,但这些动物的行为和福利受到的科学关注非常有限。本研究的目的是检查在运输到屠宰场之前将淘汰的母猪留在农场的收集栏内的临床和行为后果。观察性研究在丹麦的一个私人母猪群中进行,母猪饲养松散的妊娠和泌乳母猪。该研究包括 103 头母猪,平均胎次为 5(范围 1-9),BCS 为 3(范围 2-3)。断奶当天,对母猪进行临床检查,然后步行到同一建筑物另一部分的取料栏,每栏可容纳3-4头母猪。在围栏中,母猪可以从水杯中自由饮水,每天在地板上喂食两次,每头母猪总共 2.5 FU。平均室温为 21.0 °C(范围 18–25.6 °C)。在猪圈中放置 24 小时后,母猪的临床状况显示出恶化的迹象,根据浅表皮损数量的增加(中位数 0(范围 0-22)v. 中位数 9(范围 0-2))来判断。 75);P 0 °C(范围 18–25.6 °C)。在猪圈中 24 小时后,母猪的临床状况显示出恶化的迹象,这可以通过浅表皮损数量的增加来判断(中位数 0(范围 0-22)v. 中位数 9(范围 0-22))。 75);P 0 °C(范围 18–25.6 °C)。在猪圈中放置 24 小时后,母猪的临床状况显示出恶化的迹象,根据浅表皮损数量的增加(中位数 0(范围 0-22)v. 中位数 9(范围 0-2))来判断。 75);P
