چکیده

The present study was conducted to evaluate the in vivo fertility of frozen thawed boar semen. Twenty ejaculates collected from six mature boars were frozen in a programmable freezer. After freezing the semen was evaluated for different sperm quality parameters. Twenty five sows were inseminated artificially utilizing frozen thawed semen. The percentage of sperm motility, live sperm, live intact acrosome, plasma membrane intact sperm, HOST-reacted sperm, live sperm with high mitochondrial membrane potential, lipid peroxidised sperm and DNA-damaged sperm of frozen semen utilised for AI were 56.25 ± 0.96, 63.75 ± 1.47, 59.88 ± 1.09, 41.08 ± 1.01, 40.31 ± 1.02, 86.23 ± 1.29, 9.28 ± 0.83 and 4.20 ± 0.29 respectively. The farrowing rate was 44.00 per cent and the mean litter size at birth was 5.91 ± 0.69. It could be concluded that the freezing and insemination protocol of boar semen used in the present study resulted in moderate fertility of frozen boar semen and it would help in further improvement and utilization of frozen boar semen for AI in India.

Analysis of in vitro fertilizing capacity to evaluate the freezing procedures of boar semen and to predict the subsequent fertility.

A porcine in vitro fertilization (IVF) system and seminal quality parameters of frozen-thawed boar semen were used to assess the effectiveness of two different thawing rates of frozen boar semen, and to address the question of whether differences between fertility of ejaculates could be predicted in a limited field trial. In the first experiment, two thawing procedures were analysed (37 degrees...

Implications of the pH and temperature of diluted, cooled boar semen on fresh and frozen-thawed sperm motility characteristics.

Boar semen is typically collected, diluted and cooled for AI use over numerous days, or frozen immediately after shipping to capable laboratories. The storage temperature and pH of the diluted, cooled boar semen could influence the fertility of boar sperm. Therefore, the purpose of this study was to determine the effects of pH and storage temperature on fresh and frozen-thawed boar sperm motili...

P-65: Low-Density Lipoproteins Extractions on Boar Spermatozoa Quality Following Freezing–Thawing

Background Low-density lipoproteins (LDL) is known to protect boar sperm during freezing–thawing, but little information is known about the effects of LDL extracted from different avian egg yolks on post-thaw boar semen quality. The purpose of this study was to compare and analyze the effects of LDL at various concentrations and different species on boar sperm quality after freezing–thawing. Ma...

Use of boar spermatozoa for artificial insemination. II. Fertilizing capacity of fresh and frozen spermatozoa in gilts inseminated either at a fixed time or according to Walsmeta readings.

A fertility trial was conducted comparing two methods of defining the optimum time to inseminate frozen boar semen. One hundred sixty-four gilts were inseminated, one-half at a fixed insemination time of 32 to 34 h after calculated onset of estrus and the remainder were inseminated on the basis of changes in the vaginal mucosal electrical resistance. Inseminations were made when the instrument ...
