Feral does were used for a 2 x3 x 2 factorial, with 2 types of
insemination (cervical v laparoscopic), 3 pregnant mare serum
gonadotrophin (PMSG) levels (no PMSG, 150 i.u. 2 d before controlled
internal drug releaser (CIDR) removal and 150 i.u. at CIDR removal) and
2 sperm dose rates (50 v 100 million sperm). The semen, obtained from 9
Cashmere bucks, was frozen in straws containing 100 million sperm.
Three operators inseminated 171 does 2 d after CIDR removal. The
overall kidding rate from cervical insemination was 24% and from
laparoscopic was 50%. There was no effect of PMSG, sperm dose rate,
buck or inseminator on the percentage of does kidding.
