“…A significant difference (P<0.05) was determined between sires A and D and simultaneously among sires A, C, and D (P<0.01). Louda et al (2007), respectively Karoui et al (2011) reported sperm density in bull ejaculates from 0.8 to 2.0×10 6 mm -3 , respectively from 0.3 to 3.815×10 6 mm -3 . The minimum requirement for sperm density in relation to subsequent processing is 0.7×10 6 mm -3 (Hafez & Hafez 2000).…”

“…The volume of ejaculate ranged from 3.3 g in bull C to 6.9 g in bull D during the period observed, and differences among individual sires were determined to be significant (P<0.05-0.01). Ball & Peters (2004) reported range from 5 to 6 cm 3 , while Karoui et al (2011) assessed the overall mean volumes of bull ejaculates 5.49 cm 3 . Hafez & Hafez (2000) stated the minimum volume of bull ejaculate suitable for long-term preservation 3 cm 3 in adult bulls and 2 cm 3 in young bulls.…”

“…Collection of ejaculate and its subsequent processing present further potential risk factors. The conventional procedure for evaluating ejaculate which is performed before and after cryopreservation includes determining the volume, density, activity, and sperm morphology (Bhoite et al 2008, Karoui et al 2011. These parameters mostly detect cases of significantly inadequate reproduction or infertility in bulls (Rodriguez-Martinez 1998).…”

“…Every part of an ejaculate processing from its collection to production AI doses is very important and affects the final quality. Sperm quality is influenced by many factors, e.g., by breed, variation between individuals, and age of the sire , Štolc et al 2009, Bezdíček et al 2010, Strapák et al 2010, Hanuš et al 2011, by feeding ration composition, content of specialised feeding supplements (Čeřovský et al 2009(Čeřovský et al , Jacyno et al 2009), environmental conditions, frequency of ejaculate collection (Wolf & Smital 2009, Karoui et al 2011, and by season of the year (Hajirezaee et al 2010) or even calendar month, especially in animal species with seasonal sexual activity (Alavi et al 2010, Król et al 2011. Collection of ejaculate and its subsequent processing present further potential risk factors.…”

Effect of sire and extender on sperm motility and share of live or dead sperm in bulls’ fresh ejaculate and in AI doses after thawing

et al. 2012

The objectives were to evaluate the effects of sire and content of fresh or ionised egg yolk in extenders on sperm motility and share of live and dead sperm in collected ejaculate, in thawed artificial insemination (AI) doses, and during thermodynamic testing compared to extenders not containing egg yolk. Ejaculates were collected once a week from 4 Holstein bulls. Each of the 20 ejaculate samples from each bull was diluted with 4 different extenders. AndroMed and Bioxcell (no egg yolk) and Triladyl and Optidyl (fresh, ionised egg yolk) were used. A total of 640 AI doses were analysed. The volume of samples, sperm concentration, and percentage of motile spermatozoa were evaluated after collection, as was sperm motility after thawing of AI doses and during thermodynamic testing. Percentages of live and dead sperm were also evaluated. The data set was analysed using SAS/STAT 9.1 (SAS Institute Inc., Cary, NC, USA). The results confirmed significant (P<0.05-0.01) between-sire differences in the volume, density, and activity of sperm as well as in share of live and dead sperm after collection; in decline of sperm motility in the fresh ejaculate, after thawing, and during the entire thermodynamic test, as well as in the share of live and dead sperm after thawing. The extenders ranked by sperm motility are: Optidyl, Triladyl, AndroMed, and Bioxcell, demonstrating the higher quality of AI doses produced using egg yolk extenders. Differences in sperm motility were significant (P<0.05-0.01) during the entirety of thermodynamic testing. Egg yolk extenders had a significantly (P<0.05-0.01) higher percentages of live sperm after thawing.

Influence of selected factors on bovine spermatozoa cold shock resistance

et al. 2015

The objectives of this study were to determine the effects of sire, extender, and addition of Low Density Lipoprotein (LDL) to extenders used on the percentage rate of spermatozoa survival after cold shock. Two groups of extenders were compared: without LDL addition (control variants) and LDL enriched (experimental variants). Three extenders were used: AndroMed ® extenders, and 6-10% LDL addition into the Triladyl ® extender. In total, 12 samples of fresh semen were collected from 4 bulls during a period of 8 weeks. Bovine spermatozoa cold shock resistance (1 ± 1 °C, 10 min) was evaluated by the percentage rate of live sperm using eosin-nigrosine staining immediately and after heat incubation (37 ± 1 °C, 120 min). The results showed the effect of sire as important and individual differences between selected sires in their sperm resistance against cold shock were confirmed. AndroMed ® and Bioxcell ® were found to be providing better protection of bull semen to cold shock compared to Triladyl ® due to lower decline of live sperm proportion. Our results detected a positive effect of LDL addition on sperm resistance against cold shock, especially on lower decrease of live sperm percentage rate after 120 min of the heat test (P < 0.05). Further studies are needed to assess the optimal concentration of LDL in various kinds of extenders as well to state ideal time and temperature conditions for ensuring LDL reaction with sperm. , bull sperm, extender, LDL cholesterol, sperm survival, cold shock, eosin-nigrosine staining Reproduction
