Abstract

The effect on sperm motility and chromatin integrity of adding homologous or heterologous equine seminal plasma (SP) to fresh stallion spermatozoa selected by single layer centrifugation (SLC) was studied. No statistical difference in mean progressive motility was seen after adding SP at time 0 h,...

AbstractFull Text

Background: Artificial insemination is not as widely used in horses as in other domestic species, such as dairy cattle and pigs, partly because of the wide variation in sperm quality between stallion ejaculates and partly due to decreased fertility following the use of cooled transported...

Abstract

274 bitches were inseminated directly into the uterus using transcervical catheterization with the Norwegian catheter (NIU, 167 AI), a fiberoptic endoscope (EIU, 19 AI), or in the cranial vagina (VAG, 141 AI), during 1993-95 at the Cryogenetic Laboratories, Pennsylvania, USA and at the Department...

Abstract

Semen from Swedish Red and White bulls, 14-16 or 66-79 months of age, was cooled from room temperature to 4°C, at 4.2°/min (control split sample) or 0.1°/min (treatment split sample). Fertility values (56-day non-return rate) of the slow cooling batches (treatment) were 0.4% units higher than for...

Abstract

The present study examined the relationship between bull sperm characteristics post-thawing, after swim-up, and after challenge to calcium ionophore in relation to fertility (56-day non-return rates) after AI. Spermatozoa from 25 semen batches derived from 15 Swedish Red and White AI bulls were...

Abstract

Semen from 5 bulls, between 6 and 6.5 years of age, was split-frozen to produce straws with 15 × 106 (control dose) or 10 × 106 (treatment dose) spermatozoa each. The straws were used for 16 651 inseminations. There were no significant differences between the 2 treatments for any post-thawing sperm ...

Abstract

For 46 semen samples collected from 18 cats by electroejaculation, ejaculate volume averaged 0.046±0.027 ml, the average sperm concentration was 21.42±17.32 million, and sperm motility 57.9±22.4%. In 55 semen samples from 14 domestic cats aged <2 years, 5 cats aged >2 years, 5 pedigree cats...

Abstract

Semen from 3 boars was diluted with a modified Kiev extender, after which 5 mg PGF per semen dose was added to half of the semen and the remainder served as a control. The semen was stored at 17°C. After storage for 0, 24, 48, 72 and 96 h, sperm motility in the PGF-treated semen averaged 70.8,...
