Quality of frozen semen from crossbred boars (Ibérico × Landrace) related to centrifugation methodology
نویسندگان
چکیده
Results: There were no significant differences in semen quality associated with the shape of the centrifugation tube either for refrigerated (5 ̊C) or thawed semen. The g-force of centrifugation did affect semen quality. In refrigerated samples centrifuged at 250g, the percentage of sperm with normal apical ridges (NAR) was lower (P <.01) and the percentage of damaged acrosomes was higher (P <.01); however, motility was unaffected. Total motility was higher (P <.01) in refrigerated semen (approximately 53%) compared to thawed semen (approximately 36%), and percentage of sperm with NAR was higher (P <.01) in refrigerated semen (approximately 67%) compared to thawed semen (approximately 31%). The influence of individual boars was not detected (P >.05).

A field trial was conducted on 36 farms in the Netherlands to compare the fertilizing capacity of fresh and frozen-thawed boar spermatozoa. Four-hundred and fifty-one sows were artificially inseminated with semen that had been frozen and thawed according to the Beltsville Method or diluted in Kiev extender and inseminated on the day of collection. Twelve boars of the Dutch Landrace and Dutch La...

An experimental design aiming at analysing the consequences of genetic selection from 1977 to 1998-2000 on the evolution of stress-responsive systems in the French Large White (LW) and Landrace (LR) pig populations was conducted by INRA and IFIP-Institut du Porc. Large White sows were inseminated with semen from LW boars born in 1977 (frozen semen) or in 1998 and their second-generation offspri...
متن کاملAssociation of heat shock protein 70 with semen quality in boars.
This study attempted to clarify the relationship between the levels of 70kDa heat shock protein (HSP70) and semen quality in boars. Semen samples from 29 (13 Duroc, 9 Landrace, and 7 Yorkshire) boars (mean age=25.2+/-2.2 months) were examined. Three to four ejaculates per boar, collected during cool and hot seasons, were evaluated in terms of the sperm concentration, sperm motility, percentage ...

A total of 30 ejaculates from three Hampshire crossbred boars were used to study the effect of freezing rates and thawing methods on quality of frozen boar semen. Semen was frozen using three freezing rates-30 0 c/min, 50 0 c/min and 70 0 c/min in a programmable biological semen freezer. The semen characteristics viz., sperm motility, live sperm, HOST reacted spermatozoa and intact acrosome wer...
متن کاملDetection and duration of porcine reproductive and respiratory syndrome virus in semen, serum, peripheral blood mononuclear cells, and tissues from Yorkshire, Hampshire, and Landrace boars.
Because transmission of porcine reproductive and respiratory syndrome virus (PRRSV) can occur through boar semen, it is important to identify persistently infected boars. However, even for boars given the same PRRSV strain and dose, variability in the duration of viral shedding in semen has been observed, suggesting that host factors are involved in PRRSV persistence. To determine whether there...
