摘要: Resumo: A sexagem de semen e uma ferramenta da reproducao animal disponivel comercialmente. O objetivo desse estudo encontrar alternativa que favoreca o uso do sexado na inseminacao artificial, tornando-o economicamente viavel. Inicialmente apresentada revisao sobre processo fatores afetam os resultados. primeiro experimento (capitulo 1) foi realizado com intuito se avaliar a eficacia tecnica intracornual profunda (IAIP) dose reduzida semen, chegando resultados 67,4% 48,8% artificial convencional (IA) (p>0,05). No segundo 2), observaram-se um programa IA em fazenda bovinos corte avaliou-se custo producao bezerros, obtendo-se 23,0% taxa nascimento 46,45% nao-sexado (p<0,05). Finalmente, terceiro 3) aliou informacoes segundo, comparando-se prenhez obtida pela IAIP. Os demonstraram diferenca nao significativa usando-se as duas tecnicas, apesar das porcentagens 36,0% IAIP 48,0%
