Importance of tropical sheep introduced into the country: productive and reproductive characteristics

Sheep is an animal whose distribution is widespread throughout the world, it is found in all climates and ecologies. Thanks to this species, it has been possible to take advantage of extensive areas of poor pasture for other species, especially cattle. Hair sheep have evolved under the selective influence of nature and man. Their coat is similar to that of cattle and goats. They adapt well to tropical environments. Hair sheep contribute to various production systems in the tropics. Although the characteristics of hair sheep production systems vary from region to region, most systems are subject to the same general restrictions. The three categories of restrictions are in common are ecological, biological and socioeconomic. American Pelo sheep are more similar to the Selva Sabana type than the Sahel type, although they are generally larger than the Selva type. The current Creole sheep retain the characteristics of their ancestors (Merino and Churra sheep), but with a very deteriorated quality. Under national conditions, the Assaf and Blackbelly breeds perform better in productivity and herd efficiency. Birth weight is approximately 10% of slaughter weight. Hair sheep are a genetic resource of considerable potential for meat production in tropical regions, and possibly in temperate zones as well
