The main purpose of this study was to investigate the influence of three different rabbit rearing systems using animal-based measures. Therefore, in 2021, cortisol and IL-6 were assessed during a Biosecurity System pilot program to evaluate rabbit welfare, based on EU Regulation 2016/429 in the Apulia region of Southern Italy. The study was carried out on a total of 45 meat-type rabbits, divided into 3 groups of 15 subjects, aged approximately 60–65 days. Groups came from either: (i) a niche open-air system; (ii) a niche system in a shed with conventional cages, or (iii) an industrial system. Based on our findings, the rearing system had a significant effect (p < 0.0001) on the animal-based measures. According to the results of the stress indicators measured, cortisol and IL-6, rabbit welfare and meat quality may be affected by rabbit rearing systems.

Abstract
The main purpose of this study was to investigate the influence of three different rabbit rearing systems using animal-based measures. Therefore, in 2021, cortisol and IL-6 were assessed during a Biosecurity System pilot program to evaluate rabbit welfare, based on EU Regulation 2016/429 in the Apulia region of Southern Italy. The study was carried out on a total of 45 meat-type rabbits, divided into 3 groups of 15 subjects, aged approximately 60–65 days. Groups came from either: (i) a niche open-air system; (ii) a niche system in a shed with conventional cages, or (iii) an industrial system. Based on our findings, the rearing system had a significant effect (p < 0.0001) on the animal-based measures. According to the results of the stress indicators measured, cortisol and IL-6, rabbit welfare and meat quality may be affected by rabbit rearing systems.| File | Dimensione | Formato | |
