Abstract
<p>Domestic sheep (<em>Ovis aries</em>) is descendant from Asian mouflon and was domesticated in the Near East. Later, sheep began its dissemination to West Africa, where it is believed that the ancestry of Pelibuey sheep came from. Pelibuey sheep were brought to America by the Spaniards to feed the crew of the boats. It is unclear whether these animals came directly from West Africa or from the Canary Islands. It is considered that Pelibuey sheep entered to Mexico between 1930 and 1940, although some authors think that this breed already existed in the country in the late nineteenth century. Since 1963, Pelibuey sheep has been the most studied breed in Mexico, due to its ability to produce in tropics, as well as its high adaptability to most agro-ecological zones of the country. A brief review about productive and reproductive traits in current Pelibuey herds, allowed to conclude that they are very similar to those of the first sheep studied almost 50 years ago. Currently, the breed has been subjected to non-planned crosses with other breeds to increase productivity, which puts in risk this important genetic resource. Therefore, there is a need to realize the conservation of the breed. </p>
