Introduction The number of equine sperm used for artificial insemination (AI) in the mare was largely established by research conducted at Colorado State University in the 1970s [1-3]. The minimum insemination dose of 500 million progressively motile spermatozoa (PMS) established in these studies has been widely used as an industry standard. Clinical observations suggest that this insemination ...

Artificial insemination (AI) is widely used by veterinarians and veterinary specialists in most domestic as well as wild animal species. Reasons for use of AI instead of natural matings are diverse and different for individual species. As in humans, AI can be used as a tool to increase conception rate in animals that have fertility problems. This is usually performed in companion animals, like ...

The most important aspect when discussing artificial ins realise that there are many factors that play a role in w bitch becomes pregnant after AI. These factors inclu (fresh vs frozen), semen quality and quantity, age and stud dog and bitch, site of semen deposition (intrauter time of insemination.... just to name a few! As you important that when comparing “conception” or more co rates” that ...

Semen extended in a liquid state, together with conventional artificial insemination (AI), is the sole sperm technology used by the pig industry. Sperm technologies known for many years, such as cryopreservation, and others developed during recent years, such as sperm sexing, have not yet been integrated into commercial use. Moreover, there has recently been an explosion of new technologies, su...

Artificial insemination (AI) is an important technique in all domestic species to ensure rapid genetic progress. The use of AI has been reported in camelids although insemination trials are rare. This could be because of the difficulties involved in collecting as well as handling the semen due to the gelatinous nature of the seminal plasma. In addition, as all camelids are induced ovulators, th...

The present study was performed to assess the fertility of frozen-thawed dog semen prepared by freezing with 6% glycerol and thawing at 70 degrees C for 8 sec, and to evaluate the least number of post-thaw spermatozoa necessary to achieve pregnancy by intrauterine or intratubal artificial insemination. It was found that the pregnancy rate of intrauterine artificial insemination was 100% using 6...
