    (Nigerian Society for Animal Production., 2009) Ajala, O.O.; Leigh, O.O; Raheem, A.K.; Raji, L.O.
    Conception study was carried out via Artificial Insemination in fifteen West African Dwarf (WAD) goat does using pawpaw juice as 10% part replacement of citrate buffer in citrate egg yolk extender, 0.5 ml of semen with spermatozoa motility and concentration of 90% and 2.15 x 109 cells/ml respectively was collected through electro-ejaculation from a proven WAD buck for the study. The semen was diluted in the pawpaw juice egg yolk citrate extender. The extended semen was introduced into the cervix of in-heat does through sterilized calibrated catheter for 22 days following insemination. None of the does was observed to return to heat. Subsequently, signs of developing pregnancy were observed in the does and these climaxed with kidding by the 15 does at about 145/125 days. Our findings suggest that propornation of pawpaw juice as 10% part replacement of citrate buffer in citrate egg yolk extender is not harmful to goat spermatozoa fertilizing capacity and will not prevent conception in does following artificial insemination.
