A method of artificial insemination in captive White-tailed deer ()

摘要: Abstract Production of fawns by artificial insemination in captive White-tailed deer ( Odocoileus virginianus ) has been accomplished using frozen-thawed spermatozoa. The purpose this study was to determine if semen deposited at the posterior face os cervix could produce conception. Five hand-raised female and one male were used over two breeding seasons 1984–1985 1985–1986. vasectomized buck ued detect estrus does. does inseminated with containing least 100 million live normal cells a 60% or higher motility. catheters worked well, but due small size cervix, catheter only be passed up first cervical ring, site which deposited. Over seasons, nine spermatozoa; each doe once estrous cycle following times: 0, 6, 12, 18, 24 30 h. after detection estrus. Of spermatozoa, six conceived carried term 11 healthy fawns, yielding an overall conception rate 67%.
