  Abstract: In developing countries, rabbit breeding can be a productive option and a response to the problems of malnutrition and rural poverty. The consolidation of this activity requires the availability of techniques that allow the improvement of the reproductive indexes, using selected males that are not within reach of the small farmer. The incorporation of biotechnologies such as artificial insemination can multiply the productive characteristics of a farm. The conservation of semen depends on many factors, one of which is the ability of the extender to provide an optimal environment for spermatozoa. The objective was to evaluate rabbit semen after having been preserved at 15°C for 24 hours using extender with the addition of different doses of gelatin. The data obtained were analyzed using an analysis of variance using the LSD Fisher method. A significant difference (p < 0.05) was observed for the treatment with 1% gelatin, concluding that the addition of gelatin to the extender improves the viability and mobility of refrigerated rabbit spermatozoa.
