Resumo: Beta-Carotene concentrations were determined in 96 cows of charoláis beed wich were randomly separated during a breeding season. The samples were collected fortnightly during the first 45 days of the breeding season. The conception rate of the livestock was 62,5% of which 52% being for heifers and 73% for cows out of lactation. The average dosage obtained for Beta-Carotene concentrations was 6,58% mg/l which is much higher than the values considered to influence conception negatively, in spite of the statistically significant differences between pregnant and no pregnant animals.

As amostras foram colhidas quinzenalmente, durante 45 dias iniciais da estação de serviço. O rebanho submetido a controle apresentou um índice de fecundidade de 62,5% sendo 52% para as fêmeas nulíparas e 73% para as vacas fora de lactação. A média geral obtida nas dosagens de beta-caroteno foi de 6,58 mg/l, demonstrando estar muito acima da considerada capaz de influenciar negativamente a concepção. Entretanto, houve diferença da concentração média desta pró-vitamina entre gestantes e não gestantes, com significância estatística (P < 0,05).UEL1984-02-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/553210.5433/1679-0359.1984v5n16p71Semina: Ciências Agrárias; Vol. 5 No. 16 (1984): EDIÇÃO ESPECIAL; 71-75Semina: Ciências Agrárias; v. 5 n. 16 (1984): EDIÇÃO ESPECIAL; 71-751679-03591676-546Xreponame:Semina.
