The Merinos de Rambouillet
(The Mérinos de Rambouillet)

Aptitudes
The Mérinos de Rambouillet is the ideal prototype of the wool sheep, the improver of coarse fleeces where the locks are too loose. It also breeds naturally off-season and transmits this feature in crossings. In addition, it is a reasonably hardy breed with a preference for dry climates and can adapt to all diets.

Selection and expansion
The first selection objectives are to maintain the wool qualities and avoid consanguinity. The Rambouillet flock is composed of 120 ewes and 20 rams. It represents a particularly important reservoir of genes for fineness of wool and ability to breed off –season .A great improver of French flocks a century ago, the Mérinos de Rambouillet has also made a considerable contribution to flocks in wool producing countries.

At the present time, the flock of the Bergerie Nationale is subject to a conservation programme with the setting up of a frozen embryo collection.
