title: Technical Note: Transcervical deep cornual insemination of goats.
abstract: A newly developed technique for trans-cervical deep uterine insemination of goats is described. An experiment was conducted to compare this transcervical method with the laparoscopic intrauterine insemination using frozen-thawed semen. Of the 46 primiparous and 21 multiparous estrus-synchronized Boer goat does inseminated transcervically, 71% (22/31) kidded compared with 53% (19/36) of does inseminated laparoscopically (P < 0.025). The corresponding litter sizes were 2.27 and 1.89 (P < 0.01). In another 34 parous does inseminated transcervically without preceding hormone treatment, kidding rate and litter size were 71% and 1.76, respectively. We conclude that transcervically conducted bilateral deep cornual insemination may be considered a viable alternative to laparoscopic insemination.
