title: Fertility test for ram semen preserved at ambient temperatures by discontinuous flow dialysis.
abstract: The effect of two insemination doses (250 vs 500 x 10(6) spermatozoa) and three storage periods (0,1 or 2d) on the fertility of ram semen preserved at ambient temperatures by discontinuous flow dialysis were investigated in sheep (n=54). The 21-d nonreturn rates were 55.6, 44.4 and 27.8% for the three storage periods, and 44.4 and 40% for the two insemination doses, respectively. The corresponding lambing rates were 38.9, 16.7 and 11.1% for the three storage periods, and 25.9 and 18.5% for the two insemination doses, respectively. There were no significant differences between any of the treatments (P>0.05).
