Lameness is a response to a painful condition involving tissue damage and inflammation, leading to stress and behavioural modifications. Lameness affects millions of pregnant sows globally and can potentially reprogram foetal development. This study assessed the behavioural and physiological outcomes of offspring from Not-Lame sows (NL) and Lame sows (L). During the last third of pregnancy, locomotion assessments were performed on 30 sows, which were scored from 0 (normal gait) to 5 (severely lame) and were grouped into NL (n = 15) and L sows (n = 15). At 28 days of age, three weaned piglets from each sow were selected on the basis of weight and sex. Over three days, agonistic behaviour resulting from the controlled mixing of animals was assessed by counting skin lesions on the piglets. Piglets were subjected to a combination of Open-Field and Novel-Object tests at 31 days of age. The next day piglet nociceptive thresholds were measured with an algometer. Salivary samples were collected at 70 days of age to measure the cortisol concentration before and after transport to determine their ability to cope with stress. Linear or generalized linear mixed models were used to determine differences (p < 0.05). The results showed that NL piglets had a longer latency to the novel object than did L piglets. Piglets from NL sows presented a lower nociceptive threshold than did L piglets. The stress response to the transport challenge was greater in L piglets than that in NL piglets. Lameness during sow pregnancy can reprogram offspring behavioural, stress, and nociceptive responses, altering their coping strategies towards challenges. (AU) | |
