The objectives of this study were to evaluate ovarian changes in cows with follicular ovarian cysts following treatment with either GnRH or saline. The parameters determined were the intervals from treatment to observation of a CL and from treatment

The efficacy of using human interleukin 8 (huIL-8) as an agent for inducing cervical relaxation in estrous and diestrous sheep was assessed in a small pilot study. Multiparous, estrus-synchronized ewes were treated for either 2 or 5 consecutive days

We compared conventional methods for laparoscopic and cervical artificial insemination (AI) to a transcervical AI procedure (Guelph System for Transcervical AI; GST-AI) for use with frozen semen in Merino ewes. The GST-AI procedure was performed by a

In this study, three groups of ewes were inseminated with a transcervical intrauterine technique in order to evaluate the suitability of the technique for a commercial artificial insemination (AI) program using frozen semen. The ewes were synchronize

The differences in the embryo production potential of four rams used in a commercial embryo transfer program were examined in both in vivo and in vitro embryo production systems. Processing frozen-thawed spermatozoa through Percoll density gradients

The efficacy of oocyte selection for in vitro embryo production depends on the abundance and diameter of follicles, cumulus layers around the oocytes and subsequent fertilization. Application of 'ovum pick-up' technique allows us to utilize partially

To select rams suitable for ovine in vitro embryo production (IVP), the predictive values of the screening tests used to identify unsuitable rams need to be established. The present study examined some characteristics of frozen–thawed ram spermatoz

The effect of transferring ovine IVP embryos on Day 2 versus Day 6 postinsemination was investigated. Oocytes were collected from 35 cull ewes and cultured separately for each donor. Embryos were exposed to serum in the maturation and fertilization m

The success of estrus synchronization programs using progestagen sponges, particularly for fixed-time AI, varies considerably. In view of the recent evidence in cattle that exogenous progestins alter follicular dynamics, it may be that the stage of t

Follicular dynamics and ovulation were compared in 3 groups of anestrous ewes: those treated with medroxyprogesterone acetate (MAP) sponges for 12 d, then with 750 IU PMSG at the time of sponge removal (P4 + PMSG, n = 6), or PMSG alone (n = 6) and un
