“…Although the RT has an estimated <2% prevalence among AI‐boars (Feitsma ; Rodríguez et al. ), this disorder should be taken into consideration because of its clearly negative effects on fertility, albeit not disclosed at the semen evaluation stage. Boars with RT usually demonstrate normal sexual behaviour and seminal parameters, but they show reductions in litter size of approximately 20% due to early embryo mortality (Mäkinen et al.…”

“…Genetic disorders not affecting the seminal parameters but ultimately impairing fertility are known (McLachlan and O'Bryan 2010), among which we find reciprocal translocations (RT), where two broken-off chromosome pieces of non-homologous chromosomes are exchanged. Although the RT has an estimated <2% prevalence among AI-boars (Feitsma 2009;Rodr ıguez et al 2010), this disorder should be taken into consideration because of its clearly negative effects on fertility, albeit not disclosed at the semen evaluation stage. Boars with RT usually demonstrate normal sexual behaviour and seminal parameters, but they show reductions in litter size of approximately 20% due to early embryo mortality (M€ akinen et al 1999;Rodr ıguez et al 2010).…”

Contents In Western countries, where pig breeding and production are intensive, there is a documented variability in fertility between farms with boar‐related parameters only accounting to 6% of this total variation of in vivo fertility. Such low boar effect could be a result of the rigorous control of sires and ejaculates yielding AI‐doses exerted by the highly specialized AI‐centres that monopolize the market. However, some subfertile boars pass through these rigorous controls and consequently reach the AI‐programmes. Here, we discuss why testing young boars for chromosomal defects, sperm nuclear chromatin integrity and in vitro fertilizing ability can be discriminative and economically sound for removing these less fertile boars. Alongside, we discuss why boars differ in the ability of their sperm to tolerate cryopreservation or sex sorting.

“…Most studies testing fertility of frozen-thawed boar sperm use frozen sperm numbers equivalent to 1 to 3.0 × 10 9 motile cells or 5 to 6 × 10 9 total sperm (Rodriguez et al, 2010;Ringwelski et al, 2013). Thus, we used 5 × 10 9 total sperm for artificial insemination in our study.…”

“…Peripheral blood samples of piglets were obtained from 2 months of age for the morphological analysis of chromosomes. The chromosome analysis was based on a classical cytogenetic examination following the standard protocols of lymphocyte cultures, Leishman staining and Giemsa‐Trypsin‐Leishman (GTL) banding techniques (Rodríguez et al. 2010).…”

In this study, the karyotypes of 14 piglets from four different litters produced by intracytoplasmic sperm injection (ICSI) and embryo transfer were analysed. The chromosome analysis was based on a classical cytogenetic examination following the standard protocols of lymphocyte cultures. Two cases of reciprocal translocation [(4; 7)(p+; q-) and (2; 8)(q-; q+)] were detected in two female transgenic piglets. These animals showed neither anatomical nor physiological alterations and had normal growth. To our knowledge, this is the first karyotype study of piglets produced by ICSI.
