A tipologia das explorações de gado leiteiro no Togo mostra que o tipo tradicional (39,4%) é o mais representativo com uma predominância de zebus, incluindo a raça Goudali, o melhor produtor de leite (2,47 1,3 litros). A idade no primeiro parto (56,4 6 meses) e o intervalo parto-para-parto (21,30 2,58 meses) mostram a baixa fertilidade nestas quintas. A receptividade à inseminação artificial foi de 85,18%. O protocolo Prid(R) Delta resultou numa resposta ao cio (92,81%). A inseminação artificial ao calor induzido resultou numa taxa de parto de 47,1% e num perÃodo de gestação de 9,38 0,14 meses. Finalmente, esta biotecnologia permitiu uma redução nos perÃodos improdutivos de 16 meses para a idade do primeiro parto e de 7 meses para o intervalo entre partos. A qualidade nutricional dos leites crus estudados é satisfatória, mas a higiene praticada nestas explorações precisa de ser melhorada a fim de reduzir a taxa de contaminação. Finalmente, a fórmula barimétrica: y = 0,006z2 + 0,722x - 39,798 pode ser utilizada para controlar o peso das crias cruzadas em crescimento. Esta biotecnologia permite então o melhoramento genético da produção de leite.
