Abstract

In pig production, Pietrain and Duroc lines are often used as terminal sire lines to produce crossbred slaughter pigs. The objective of this study was to identify the differences in paternal fertility and mortality during the suckling period of crossbred progeny from Pietrain and Duroc terminal...

Abstract

In the quest for predicting fertility of an individual, enhancing semen handling, dilution and storage protocols, and understanding the impact of environment and, andrologists have changed their approaches to semen analysis. The technologies used today are fast developing and readily implemented in ...

Abstract

Multiple trait selection indexes in pig breeding programmes should take into account the population structure and time delay between parent selection and expressions of traits in all production levels next to the trait impacts on economic efficiency of production systems. Gene flow procedures could ...

Abstract

Establishing breeding programmes for preserved autochthonous breeds might be a good way for their sustainable utilization. The goal of the genetic evaluation according to breeding programme is to select breeding animals which will be used by the larger number of farmers. Connectedness between...

Abstract

The objective of this study is to apply the bioeconomic model described in a companion study (see Wolfová et al., 2017) for the calculation of the economic weights of traits of pig breeds involved in the three-way crossing system of The Czech National Program for Pig Breeding. Dam breeds, Czech...

AbstractFull Text

The widespread use of artificial insemination in the pig industry has provided breeders with access to genetic material from superior boars from around the world. Selection of parent stock is based on estimated breeding values (EBVs), which are regularly computed in all countries performing genetic ...

Abstract

Antagonistic relationship between milk yield and reproduction is reported in several livestock species. This study aimed to investigate whether genetic merit for milk production in dairy sheep affects responses to superovulation, embryo yield and quality. A total of 21 cross-bred Sarda × Lacaune...

Abstract

Background: Structural chromosome abnormalities are well known as factors that reduce fertility rate in domestic pigs. According to large-scale national cytogenetic screening programs that are implemented in France, it is estimated that new chromosome abnormalities occur at a rate of 0.5% in...
