The effect of hay on the behaviour of caged rabbits (Oryctolagus cuniculus)
To examine the effect of hay on behaviour of caged rabbits, Oryctolagus cuniculus, a study was carried out on 86 rabbits, kept in wire cages with no access to hay in one period and with access to hay in a second period. As the study was part of a larger experiment analysing the rabbits’ behaviour […]
Group Housing and Enrichment Cages for Breeding, Fattening and Laboratory Rabbits
The commercial breeding of rabbits in individual cages presents a number of problems with respect to animal protection legislation. These problems are first presented in an overview of the subject. Starting from the behaviour shown by domestic rabbits in a richly structured near-to-nature enclosure, a new concept for keeping breeding groups is presented. In the […]
Aversion to the inhalation of nitrogen and carbon dioxide mixtures compared to high concentrations of carbon dioxide for stunning rabbits
Stunning by inhalation of nitrogen (N2) and carbon dioxide (CO2) mixtures reduces aversion compared to high concentrations of CO2 in pigs and poultry. The objective of the study was to assess the aversion to 90% of CO2 (90C) and an alternative gas mixture of 80% N2 and 20% CO2 (80N20C) in commercial rabbits (Oryctolagus cuniculus). […]
Effect of Breed, Cage Type, and Reproductive Phase on Fecal Corticosterone Levels in Doe Rabbits
Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of 252 doe rabbits were randomly assigned to 2 […]
Effects of space allowance in the waiting area on agonistic interactions and heart rate of high and low ranking horned dairy cows
One possible alternative to avoid the disbudding of calves is to keep the cows horned. This, however, requires adapted housing conditions. An important aspect to reduce agonistic interactions that may lead to injuries is to provide appropriate space allowances in all parts of the stable. This study investigated the influence of three different space allowances […]
Effect of Cage Type on Fecal Corticosterone Concentration in Buck Rabbits During the Reproductive Cycle
Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and reproductive phase (estrous synchronization of doe rabbits, artificial insemination, partum, […]
Social Behavior of Adult Male New Zealand White Rabbits Housed in Groups or Pairs in the Laboratory
Rabbits are usually singly housed in laboratories, but a new emphasis on providing social housing for social species has prompted exploration of alternative housing for this species. However, a paucity of literature on the social behavior of rabbits in captivity has prevented scientific-based recommendations for appropriate housing. This study involved a descriptive analysis of the […]
