Vagino-cornual cannulation and embryo recovery from crossbred (Bos indicusxBos taurus) heifers

Successful vaginal and bicornual cannulations were performed with a tabular cannulator shaped like a giant hypodermic needle in corssbred (Bos indicus x Bos taurus ) heifers (n=7). A total of 58 embryos from a possible 73 were flushed out. The embryo recovery rate was 79.45% and average recovery time was 50 minutes. The wound healing at cannulation sites was rapid. All heifers except one conceived due to insemination during subsequent cycles. One heifer developed pyometra and did not settle.
