Este estudo foi realizado para avaliar os efeitos da suplementação de vacas Nelores em lactação com sais de cálcio de ácidos graxos de cadeia longa (Ca-SCACL) feitos com óleo de soja sobre a competência in vitro de oócitos, taxa de clivagem, taxa de produção de embriões, taxa de prenhez e proporção de sexo de embriões transferidos. Foram utilizadas 15 vacas Nelore (lactantes, multíparas e mantidas em pastagem de Tifton 85) distribuídas em dois tratamentos: (1) suplemento sem inclusão de lipídios (CONT, n = 6) e (2) suplemento contendo 47,2 g Ca-SCACL/kg (para proporcionar uma ingestão de 0,2 kg Ca-SCACL/dia) com base na matéria seca (n = 9). Os animais foram submetidos a 2,53 ± 1,35 rodadas consecutivas de aspiração folicular a intervalos de 27,65 ± 21,72 dias. Os oócitos foram avaliados morfologicamente, selecionados, maturados, fertilizados e cultivados para produção de embriões in vitro. Em seguida, os embriões foram transferidos para receptoras previamente submetidas a um protocolo de transferência de embriões em tempo fixo. O número de oócitos aspirados, a proporção de oócitos viáveis, a taxa de clivagem, a porcentagem de embriões, a taxa de prenhez e a proporção de sexo de embriões não foram afetados quando as vacas Nelore foram suplementadas com Ca-SCACL de óleo de soja em comparação com as vacas Nelore não suplementadas. Em conclusão, nossos resultados sugerem que suplemento contendo 47,2 g de Ca-SCACL/kg (para fornecer uma ingestão de 0,2 kg de Ca-SCACL) não afeta a produção in vitro de embriões de vacas Nelore em lactação. No entanto, novos estudos utilizando doses mais altas de gordura na dieta poderiam ser úteis para determinar o seu potencial sobre produção embrionária in vitro.Downloads
