Abstract

Artificial insemination (AI) is the single most important assisted reproductive technique devised to facilitate the genetic improvement of livestock. In the swine industry, it has broadly replaced natural service over the last number of decades which has been made possible by the high pregnancy...

AbstractFull Text

This study was designed to determine the degree and type of bacterial contamination in boar semen (79 ejaculates from Large White and Landrace boars) and its consequences for sperm quality during storage (27 extended semen samples, 16°C for five days) under practical conditions of artificial ...

Abstract

The purposes of this study were to evaluate the effect of both of boar and frozen boar semen concentration on the frozen-thaw sperm viability. The freeze boar semen were produced using boars from Changhua Animal Propagation Station and than thaw and insemination. The conception rate and litter size ...

Abstract

Boar stations raise only entire male pigs for selection as reproductive boars, but the majority of them will fail the selection process, ending at slaughter with a high risk of boar tainted meat. The aim of this study was to investigate whether a single dose of Improvac given to 16-week old boars...

Abstract

The economic impact of selection for semen traits on pig production systems and potential interaction with artificial insemination (AI) technique and semen dose remains partially understood. The objectives of this study were to compare the financial indicators (gross return, net profit, cost) in a...

Abstract

Background: Semen extenders are used to create multiple insemination doses from a single ejaculate and contain buffers and nutrients suitable for storage of spermatozoa. The purpose of this study was to evaluate the survivability of boar sperm stored under room temperature in different extenders...

Abstract

To investigate the effects of different diluents on the quality of the boar semen stored at 17°C, and assess the relationship between sperm motility and the relative levels of enzymes, three commercial diluents (Diluent I, Diluent II and Diluent III) and three boar breed semens (Yorkshire, Landrace ...

Abstract

In this article the factors affecting semen quality, fertilizing capability, semen assessment, spermatozoa concentration in boars are discussed highlighting the reasons why some boars with good semen quality have very low reproductive performance, fertility and/or prolificacy when used at the farm...
