Artificial Insemination with Canine Semen
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 ...
متن کاملQuality of fresh and chilled-stored raccoon dog semen and its impact on artificial insemination efficiency
BACKGROUND The aim of the study was to evaluate the quality of fresh raccoon dog semen and raccoon dog semen stored at 4 °C. The qualitative evaluation was based on apoptosis in the sperm cells, which was tested by the Annexin V/Pi assay, the TUNEL method and JC-1. In addition, the suitability of the semen for insemination and its effect on reproduction in females were determined in relation to...
متن کاملEffects of added caffeine on results following artificial insemination with fresh and refrigerated rabbit semen.
Lactating rabbits (n=1335) were artificially inseminated to study the effect of the addition of caffeine on rabbit semen stored for up to 96 h. Concentration of 0-5 mM/l were tested. Whereas a concentration of 0.2 mM/l increased spermatozoa motility, higher concentration values adversely affected reproductive parameters. Spermatozoa stored at 18 degrees C for 72-96 h did not have the capacity t...
متن کاملImpact of pig insemination technique and semen preparation on profitability.
Artificial insemination technique and semen preparation impact boar utilization efficiency, genetic dissemination, and biosecurity. Intrauterine (IUI) and deep intrauterine (DUI) AI techniques require lower number of spermatozoa per dose compared to conventional (CON) AI. Frozen semen (FRO) has been associated with lower reproductive performance compared to fresh semen (FRE) preparation. The co...
متن کاملChallenges in pig artificial insemination.
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...
