20.500.12556/RUL-179036 Different approaches to caponisation of cockerels and their relation to welfare The aim of this study was to improve surgical caponisation and identify stress factors associated with different pain management methods and post-operative periods. A total of 72 Prelux-G cockerels were caponised at six weeks of age. Eight experimental groups were established based on caponisation status and pain management. Four groups were caponised using different pain management protocols (none, anaesthesia only, analgesia only, or both), while four non-caponised groups served as controls, including one group that received anaesthesia and analgesia without surgery. The remaining three groups served as non-caponised controls with varying levels of handling. The researchers monitored body weight, feed intake, respiratory and heart rate, vocalisations, response to pain, and depth of anaesthesia. The results confirmed that caponisation is painful, as reflected in increased physiological responses and vocalisations. The use of non-steroidal anti-inflammatory drugs alone did not provide effective pain relief. Additionally, the surgical procedure had no significant effect on weight gain or feed intake during the seven days following surgery. Stress levels, measured by blood serum corticosterone concentration, also increased during the procedure. The study concludes that anaesthesia significantly reduces pain and facilitates surgery, which is essential for improving animal welfare. chickens surgery cockerels caponisation animal welfare corticosterone kokoši kirurgija mladi petelini kaponizacija dobrobit živali kortikosteron true false true Angleški jezik Slovenski jezik Članek v reviji 2026-02-04 04:36:36 2026-02-04 16:13:02 2026-02-05 04:27:08 0000-00-00 00:00:00 2026 0 0 22 str. iss. 3, art. 355 Vol. 16 2026 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 636.09:617 2076-2615 10.3390/ani16030355 267101699 Different_approaches-Zlabravec.pdf Different_approaches-Zlabravec.pdf 1 46100DC3E797B84971C99B42D3FBC877 75b2f31d3f66e1bf13acb2499208bebc5f96f4001fef3bfae72a3ba31157a9c9 4c3bc003-01dc-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227181 https://www.mdpi.com/2076-2615/16/3/355 1 a2ea6207-017a-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227131 Veterinarska fakulteta 0 0 0
