Abstract: An experiment utilizing wild rabbits (Oryctolagus cuniculus algirus) was conducted to evaluate the number of faecal pellets dropped by the animals in 24 h. When fed with a diet of known composition. Twenty four individually cage-born adult wild rabbits, coming from the Southern Iberian Peninsula (Spain), were fed with a commercial feed having 16.5% Crude Fibre, 16.5% Crude Protein, 89.8% Dry Matter. The average number of faecal pellets dropped per rabbit in 24 h measured during 6 consecutive days, was 373, remaining homogeneous along the days for each rabbit, but with differences between individuals. Values found in this experiment differ from that of the wild rabbit in many locations in its distribution area around the world. The results confirms that the number of faecal pellets dropped daily by the wild rabbit is recommended to be locally tested every time the population size of an area is to be evaluated with the purposes of game management, pest control and in assessing of risk of propagation of the diseases.
