Demi-embryos (produced by destroying 1 or 2 blastomeres of 2- or 4-cell embryos, respectively) and intact mouse embryos were cultured to the blastocyst stage, stored at -5 degrees C for 48 h, then cultured for 24 h and transferred into pseudopregnant

Bovine oocytes matured in vitro for 26 hours were electrically stimulated 1) by a single pulse (Treatment A); 2) by 3 pulses 30 minutes apart (Treatment B); 3) by a single pulse followed by 5 minutes of incubation in the stimulation medium (Treatment

The effect of partial dehydration on the ability of mouse blastocysts to withstand storage at subzero temperatures without freezing was studied. The embryos were equilibrated with a supercooling medium developed at the Centre for Food and Animal Rese

The effect of inducing nucleation of ice (seeding) and of holding semen at −5°C on the survival of boar spermatozoa was studied. The semen, in 0.5-ml straws, was protected by 2, 4 or 6% glycerol, frozen at suboptimal (1°C min −1 ) or optimal (3

The effect of supercooled storage (at subzero temperatures without ice formation) on compacted mouse morulae and early blastocysts was studied. The embryos were equilibrated with one of three storage solutions containing 1, 3, or 6% each of methanol

A new, rapid, thermal stress test for assessing the viability of boar semen, requiring only 45 min of incubation at 42.5 degrees C, was developed and compared with a widely used stress test of 180 min incubation at 37 degrees C. The shorter procedure

The effect of various thawing velocities on the motility and acrosomal maintenance of ram spermatozoa frozen at 20 degrees C/min (optimal) or 2 degrees C/min (suboptimal) was studied. The freeze-thaw motility and the percentage of intact acrosomes of

The interaction of glycerol concentration from 0 to 16% and cooling velocity from 1 to 100 degrees C/min on freeze-thaw survival of ram spermatozoa was studied using a diluent based on 15% skim milk (450 mOs/kg water). Optimal spermatozoa survival (p
