Reproductive performances of the Creole goat, the meat breed of Guadeloupe in the Caribbean, are described from a database generated for 15 years (1973 to 1988) at an experimental farm of the Institut National de la Recherche Agronomique (INRA, Guadeloupe, French West Indies). The data contain information on 599 females, 2259 attempted matings, 2135 achieved matings and 1904 kiddings. Animals were reared under semi-intensive management conditions (on the basis of feeding system, health and culling policy). Main sources of variation were analysed: mating type (buck in permanence or buck effect), mating season (dry, intermediate and humid season) and rank of kidding. The Creole goat is a continuous breeder. On average 94.5 percent of exposed females were mated (defined as mating rate) and 90.5 percent of exposed females achieved a kidding (fertility rate). Their prolificacy reached 1.98 kids/kidding, with only 3.9 percent of kids born dead. These reproductive parameters varied essentially with rank of kidding but very poorly with the mating season. Productivity of these females was regularly high during their whole lifetime production. From the results obtained, it is concluded that Creole goats have very high reproductive performances, provided that animal husbandry and nutrition are adequate.
