Identification and monitoring of farm animals are effective tools for traceability. Current livestock identification systems are not 100% efficient and present certain disadvantages such as losses, breakages and an unreadable identification code. The use of injectable transponders may be a reliable method for individual identification, providing an improvement in data recording and farm management. The aim of this experiment was to evaluate the practical aspects concerning injection technique, readability and retrieval of injectable transponders in live rabbits. A total of 60 rabbits (40 fatteners and 20 does) were injected with 23x3mm passive FDX-B transponders (Datamars, Switzerland), inserted into a needle,...
This paper reports on the design of a nest box consisting of two compartments for the breeding in cages of wild rabbits(Oryctolagus cuniculus). The first compartment was a chamber measuring on the inside 17x23x20 cm (base and height), conforming to the small body size of the wild rabbit and similar to its breeding burrows. A plastic tray was placed inside the chamber, in which the doe could build her nest. The other part of the nest box was a tunnel with an inner cross-section of 9x8 cm leading to the nesting chamber and designed to make the doe enter the...

The aim of the paper was to analyse the effect of collection rhythms on spermatozoa and droplet concentration of rabbit semen. Thirty adult New Zealand White rabbit bucks were submitted to 3 collection rhythms: every day (D), every week (W), every 2 weeks (2W). The trial lasted 71 days and a total of 790 ejaculates were collected. Volume, concentration of spermatozoa, droplets and their dimensions were evaluated. Ejaculate volume and concentration of spermatozoa were the lowest (0.37±0.08 mL and 48.9±43.8x106 mL-1, respectively) when the samples were collected daily, whereas the ratio droplets/spermatozoa was the highest (6.4±3.3). The output of spermatozoa...

An experiment was conducted to measure recycling through cecotrophes and retention of conjugated linoleic acid (CLA) in the body fat of rabbits. A commercial diet was formulated and given ad libitum to six New Zealand x Californian rabbits. Animals were weaned at 25 days of age and were reared in individual cages for five weeks, reaching an average body weight of 2.5 kg. Excretion of soft faeces was individually determined for 24 h after putting a wooden collar around the animals' neck. Ether extract content and fatty acid profile were determined in both soft and hard faeces, and also in...

Research on rabbit welfare has been fragmentary and to date has been performed by only a few European teams who have often neglected the productive and commercial aims of rabbit rearing. With European Project COST Action 848 (Multi-facetted research in rabbits: a model to develop healthy and safe production in respect with animal welfare), rabbit welfare began to be considered in European research projects with the focus mainly on ethology, welfare evaluation methods, doe-litter relationships, man-animal relationships, and reproducing and fattening housing systems. As regards legislation, since 1996 the Standing Committee for the protection of animals kept for farming purposes...

The aim of this experiment was to study the carcass traits of rabbits when the same maternal stocks were mated with bucks of two well-known hybrids selected for growth traits or with Pannon White bucks selected for carcass traits by CT (computerised tomography). Three experiments were carried out at the same time. Experiment 1: Pannon White (P) or Hycole terminal (H) males were crossed with Pannon White (P) does (n=PP: 60, HP:59). Experiment 2: Pannon White (P), Hycole terminal (H) or Zika terminal (Z) bucks were crossed with Hycole (H) parent does (n=PH: 60, HH:52 and ZH:58). Experiment 3: Pannon...
