Abstract

Sperm quality was assessed in normozoospermic human (n=10) and Spanish breed stallion (n=10) after sperm fractionation during ejaculation. The first ejaculated fraction was separated from the second. A third sample was reconstituted using equivalent proportion of both fractions (RAW). Fraction 1,...

Abstract

The Cantabrian brown bear survives as a small remnant population in northern Spain and semen cryopreservation for future artificial insemination is one of the measures being implemented for conservation of this species. As part of this program we investigated the value of adding heat shock protein...

AbstractFull Text

Sperm selection techniques have became an important tool to improve sub fertile ejaculates. The main aim of this study was to assess the dynamics of motile sperm subpopulations of ejaculates from subfertile stallions subjected to density gradient centrifugation (DGC) involving a double layer...

Abstract

Semen samples collected in 2012 from 1785 boars belonging to five different breeds were recruited from the quality control laboratory of Magapor SL, Spain. These samples came from 43 boar studs and resulted from diluting the ejaculates in commercial semen extenders. Evaluation of the semen sample...

Abstract

The present study investigated the effect of inbreeding depression on sperm quality using automated and objective methods and subsequent effects on beef bull field fertility. Individual inbreeding coefficient (F) values and field fertility data were determined using a dataset of AI bulls belonging...

AbstractFull Text

A group of boars from the same Duroc line breed was associated with a reduction of the fertility in commercial farms averaging from 90 to 75%. The sperm analysis at the artificial insemination centre only detected a moderate reduction of the motility and increased number of spermatozoa with...

Abstract

A collection of 180 chilled boar semen samples, randomly chosen from stocks currently used for routine characterization of standard seminal quality, were studied for DNA fragmentation status using the sperm chromatin dispersion test and the DNA fragmentation index (DFI: percent of abnormal cell...

Abstract

This study was carried out to assess the in vitro quality of canine semen frozen in an ultrafreezer at -152°C and to evaluate the male-to-male variation of frozen semen in five male dogs of the Canarian Mastiff breed. Four ejaculates of each dog were processed individually (5% glycerol and 0.5%...

Abstract

The quality of 32 281 refrigerated samples of boar semen from various artificial insemination centres in Spain was investigated. The parameters examined were: the percentage of normal acrosomes as shown by phase contrast microscopy; the percentage of motile spermatozoa with and without the addition ...

Abstract

Artificial insemination (AI) in rabbits is not extensive in the breeding programmes of the rabbit meat industry. A limiting factor is related to the semen preservation. In order to improve the use of AI, two experiments have been conducted to evaluate sperm viability and fertility of rabbit semen...
