Different extenders solutions for tambaqui semen cooling

The objective of this work was to evaluate the efficiency of extenders solutions in tambaqui (Colossoma macropomum) semen cooling at 6°C. The treatments consisted of semen dilutions with three extenders - BTS, HBSS, and ACP-104 -, and a control with undiluted semen. Cooled semen was evaluated by 24,...

Description
Summary:The objective of this work was to evaluate the efficiency of extenders solutions in tambaqui (Colossoma macropomum) semen cooling at 6°C. The treatments consisted of semen dilutions with three extenders - BTS, HBSS, and ACP-104 -, and a control with undiluted semen. Cooled semen was evaluated by 24, 48, 72, 96, and 120 hours. There were differences for the duration of motility and fertilization rates among the semen dilutions. Motility duration proved a highly variable evaluation after 72 hours. Dilution testing can be performed by the three products, and cooling storage for 72 hours is most effective with BTS extender. Resumo: O objetivo deste trabalho foi avaliar a eficiência de soluções diluidoras no resfriamento do sêmen de tambaqui (Colossoma macropomum) a 6°C. Os tratamentos consistiram de diluições de amostras de sêmen com três soluções - BTS, HBSS e ACP-104, e de um controle com sêmen não diluído. O sêmen resfriado foi avaliado por 24, 48, 72, 96 e 120 horas. Houve diferenças quanto à duração da motilidade e taxa de fertilização entre as diluições do sêmen. A duração da motilidade mostrou-se altamente variável depois de 72 horas. Os testes de diluição podem ser realizados pelos três diluidores, e seu armazenamento por 72 horas é mais eficaz com o diluidor BTS.
