Abstract: | Obtaining measures of an animal's physiological state with minimum disturbance to the animal is essential in animal welfare studies and it is also ethically desirable. A simple technique for implanting a temporary jugular catheter in adult sows is described. The technique involves implantation via an ear vein and can be performed in 5-7 min. Local but not general anaesthetic is required. The technique has no effect on basal levels of salivary cortisol 1-2 h later, suggesting that it has no long term stress consequences. Catheters continue to function perfectly well after 4 h. |
