The present work describes experiments undertaken to evaluate the usefulness of selected physicochemical indices of semen, cell membrane integrity and sperm chromatin structure for the assessment of b...
In an attempt to understand the biochemical mechanism for the synthesis of the anabolic steroid, 19-nortestosterone, produced by prepubertal boar testes and its physiological role, normalized compleme...
A series of experiments were conducted to determine the suitable freezing and thawing temperatures for the freezing of boar semen in 5 ml maxi-straws. The ultrastructure, in vitro fertilization (IVF) ...
This study was designed to develop a method of liquid storage of boar sperm at 4??C by using the modified Beltsville F5 (BF5) diluent with bovine serum albumin (BSA) and N-acetyl-D-glucosamine. Boar s...
The objective of this study was to investigate the effects of dehairing methods and sex on various traits of pork quality, as well as on tissue levels of the boar taint compounds androstenone and skat...
This study is based on the karyological analyses of 4 Sus scrofa specimens obtained from Kırıkkale province in 2003 and 2005. It is the first time that karyotypes of Turkish wild boar specim...
The objective of this study was to investigate the anti-oxidative effects of taurine on sperm characteristics for in vitro storage of boar semen. Semen was randomly divided into 10 groups in conical t...
In order to protect the spermatozoa against cold shock, hen egg yolk is widely used as a cryoprotective agent in semen freezing extenders for domestic animals. The protective action of yolk is largely...
Currently, boars selected for commercial use as AI sires are evaluated on grow-finish performance and carcass characteristics. If AI sires were also evaluated and selected on semen production, it may ...
The percentages of sperm motility and normal acrosome on the liquid boar semen diluted and preserved at 4 C with lactose hydrate, egg yolk and N-acetyl-D-glucosamine (LEN) diluent were significant dif...
This study was carried out to compare the semen characteristics, frozen-thawed sperm viability and testosterone concentration and in vitro fertilization (IVF) and development of in vitro matured pig o...
This study was carried out to investigate in vitro fertilization and development of in vitro matured pig oocytes inseminated with the Duroc boar sperm by different sperm washing media after thawing of...
