Association between sperm morphology and sperm count of boar semen

Polish Journal of Veterinary Sciences, 2023
The number of spermatozoa in the ejaculate is important for its quality and that of the sperm contained in it. The number of ejaculated spermatozoa is also associated with sperm dimensions. The aim of this study was to assess the morphological structure of sperm and the frequency of morphological abnormalities in sperm on the ejaculation performance of

Accessory sperm: a biomonitor of boar sperm fertilization capacity

Theriogenology, 2005
The number of accessory sperm found in the zona pellucida of porcine embryos was correlated to their individual quality and to the embryo quality range found within a single sow. Our goal was to determine whether accessory sperm counts provide semen evaluation with additional, useful information.

The thermal denaturation of nucleoprotein in boar sperm

Journal of Molecular Biology, 1965
The paper describes a study of the thermal denaturation of DNA in intact boar sperm. A recently designed microspectrophotometer was used to measure the integrated absorption at 260 m μ of sperm after they had been heated in several media. Denaturation was detected with heating media containing 70% glycerol and 30% of a sodium chloride-sodium citrate ...

New Aspects of Boar Sperm Encapsulation

Reproduction in Domestic Animals, 2011
ContentsThe study takes into account the main steps and techniques for boar semen encapsulation, to optimize the instrumental insemination interventions. The use of cheap, biocompatible polymers as alginate can assure a regular, constant release of spermatozoa in the sow reproductive system, avoiding the double/triple intervention of insemination and ...

Boar Sperm Encapsulation ReducesIn VitroPolyspermy

Reproduction in Domestic Animals, 2010
A boar sperm encapsulation technology in barium alginate has been developed to enhance reproductive performances and spermatozoa preservation time; aim of this work was to evaluate the effect of in vitro sperm encapsulation on polyspermy as a function of storage time at 18 degrees C.

ACROSOME REACTION IN FERTILE AND SUBFERTILE BOAR SPERM

Archives of Andrology, 2002
The main purpose of sperm evaluation is to predict its fertilizing ability. However, basic sperm test results show a low correlation with fertilizing ability. The purpose of this study was to determine whether there is an association between acrosome reaction (AR) and the incidence of subfertility of normal sperm boar.

Improvement of the motility of boar sperm after cryopreservation

Animal Reproduction Science, 2020
After the sperm cryopreservation process, there frequently is a marked decrease in sperm motility, however, this loss of motility could be avoided or reduced by modifying the thawing extender. The aim of conducting this study was to evaluate treatments resulting in differences in pH of the thawing extender on post-thawing sperm quality, especially ...

Effect of dietary selenium on boar sperm quality

Animal Reproduction Science, 2013
The primary objective of this research was to evaluate the effect of long-term dietary selenium supplementation of commercial swine diets on semen production and sperm quality. The dietary treatments were a non-supplemented basal diet or the basal diet supplemented with 0.3ppm selenium in either an organic or inorganic form.

Effects of boar sperm antioxidant supplementation on fertility

Animal Reproduction Science, 2022
Use of cooled stored boar semen for artificial insemination accounts for 99% of inseminations in pork production sectors worldwide. The aim of the present study was to examine use of GameteGuard®-CP, a natural plant derived blend of antioxidants, supplemented in one commercially available semen extender on sperm quality, conception rate, farrowing rate,
