Use of manual stimulation for collection of semen from an atactic stallion unable to mount.
A 9-year-old atactic breeding stallion was trained to ejaculate, with only manual stimulation, while standing on the ground. Ejaculates obtained yielded fertile semen with morphologic and motility characteristics within the range for normal stallions. This method extended the breeding life of a stallion unable to mount a live or dummy mare or to ejaculate into an artificial vagina while standin...
متن کاملPhysiological Aspects of Stallion Semen Cryopreservation
The history of artificial insemination (AI) begins with a story about some Arabs stealing stallion semen from a rival tribe and bringing it home for breeding in a sponge. When AI began its modern development in Russia during the early 20th century by Ivanov, the main object was not cattle but horses as documented by Milovanov. In the late 1940s, Christopher Polge, working with chicken and the e...
متن کاملStallion ejaculation induced by manual stimulation of the penis.
This paper reports the use of a procedure for collection of semen from stallions by manual stimulation of the penis while the stallion is standing. Our use of this method with 18 stallions of various ages and types of semen collection experience indicates that this method may be an efficient alternative to traditional semen collection techniques using an artificial vagina and stimulus mare or d...
متن کاملIn Vitro Evaluation of Frozen-Thawed Stallion Semen: A Review
The article reviews methods used for in vitro evaluation of sperm, with particular emphasis on frozen-thawed stallion sperm. The techniques, limitations of the methods and correlations with fertility results are discussed. Very few studies have tried to find correlation between fertility of frozen stallion semen and laboratory tests. It is difficult and expensive to inseminate an adequate numbe...
متن کاملFreezing stallion semen with the new Cáceres extender improves post thaw sperm quality and diminishes stallion-to-stallion variability.
Ejaculates from 7 stallions were split and simultaneously frozen in three different extenders, INRA 96 egg yolk glycerol, Ghent and the newly developed extender Caceres. After thawing, samples were evaluated for motility (CASA system) sperm membrane integrity and early membrane changes (YoPro-1/Eth staining), acrosome integrity (FICT-PNA), and mitochondrial membrane potential (JC-1) (flow cytom...
