Ovum Transport in the Ewe

The transport of sheep and goat spermatozoa in the ewe.

Counts were made of the numbers of spermatozoa in the Fallopian tubes of ewes 24 hr after mating or after insemination with either sheep or goat semen. Spermatozoa were recovered from all five mated ewes (10/10 tubes), from all eight ewes inseminated with sheep semen (13/15 tubes) and from four of eight ewes inseminated with goat semen (7/16 tubes). The calculated mean numbers of spermatozoa pe...

Pregnancy diagnosis in the ewe.

A total of 378 ewe lambs were evaluated for signs of pregnancy using five methods of detection. The methods used were breeding mark, rectal-abdominal palpation, an intrarectal Doppler instrument and two ultrasonic devices, the Scanoprobe and Scanopreg (Model 738) for sheep. Accuracies of pregnancy diagnosis based on grease marks at mating vs lambing results were 65.7% in 1976 and 75.5% in 1977 ...

Sperm transport into the cervix of the ewe after regulation of estrus with prostaglandin or progestogen.

Mature ewes (12 per group) were given prostaglandin F20t (PG; 10 mg intramuscularly) on day 10 of an estrous cycle, to regress corpora lutea, or on day 16, after natural corpus luteum regression. Ewes treated on day 10 or 16 were in estrus on day 12 or 17, respectively. The PG-treated and untreated ewes were mated at estrus and necropsied 2 hr later. Sperm were counted in the oviducts, the uter...
