Effect of Feeding a DHA-Enriched Nutriceutical on Motion Characteristics of Cooled and Frozen Stallion Semen (21-Nov-2003)
نویسندگان
چکیده
Elevating the level of specific omega-3 fatty acids in equine semen by dietary modification can improve motion characteristics of cooled-stored and frozen-thawed sperm. Stallions, which produce semen that has poor tolerance to cooling and freezing, would benefit most from this dietary modification.

Pregnancy rates of mares inseminated with semen cooled for 18 hours and then frozen.
The ability to ship cooled stallion sperm for subsequent freezing at a facility specializing in cryopreservation would be beneficial to the equine industry. Stallion sperm has been centrifuged, cooled to 5 degrees C for 12 h, and frozen without a detrimental effect on motility in a previous study; however, no fertility data were available. Experiment 1 compared the post-thaw motility of sperm c...
متن کاملAn analysis of Selected Aspects of Sperm Quality in Fresh and Cooled-Storage Stallion Semen
This review summarises the most significant findings related to the issue of the quantitative and qualitative indicators of stallion ejaculates, its processing when producing chilled insemination doses and the possibility of influencing the individual steps of the entire process. Artificial insemination, with cooled-storage semen, is increasingly used in horse breeding because it offers many ad...
متن کاملSupplementing Fatty Acids to Improve Sperm Characteristics
Artificial insemination via cooled or frozen-shipped semen allows more mares to be bred to a single stallion, but not all stallions produce semen capable of withstanding the cooling and freezing procedures. Aurich et al. (1996) estimated that cooled or frozen-shipped semen achieves < 75% of the pregnancy rates achieved with fresh semen. Some factors affecting the fertility rates of thawed semen...
متن کاملDifferences in ability of jennies and mares to conceive with cooled and frozen semen containing glycerol or not.
A suitable method for the cryopreservation of donkey semen would be very valuable for the ex situ management of genetic diversity in this species. This report uses a variety of observation and trials to evaluate the effect of cryoprotectants in per-cycle pregnancy rates (PC) in equids females (jennies (donkey) and mares (horse)). This was explored by (1) comparing the results of insemination of...
متن کاملEffects of in vitro copper sulphate supplementation on the ejaculated sperm characteristics in water buffaloes (Bubalus bubalis)
This study was carried out to investigate effects of copper sulphate (CuSO4) additive to semen extenders on sperm parameters: progressive motility, viability, membrane integrity and DNA damage, after semen dilution and cryopreservation. Semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occasions during the autumn 2011. A total number of 25 samples were u...
