“…The AA genotype proved the largest litter size. Our study indicates that the myogenin gene influences the reproduction traits such as service period and insemination interval; nevertheless we did not confirm the results of Horák et al (2004). Because of such a low number of sows with BB ge-notypes further study is necessary to say the last word about the usefulness of the MYOG gene in practical breeding.…”

“…Our study did not confirm these effects. The influence of the myogenin gene on reproductive traits was studied only by Horák et al (2004) in the population of Přeštice Black-Pied sows. They found significant differences between the numbers of piglets weaned in sows with AA and AB, BB genotype in the 1 st -6 th parities and in the 2 nd to 6 th parities.…”

“…The myogenin gene (MYOG) plays a role during the terminal transformation of myoblasts into myofibres (Te Pas and Visscher, 1994). The effect of MYOG gene on reproductive traits was reported only by Horák et al (2004). Te Pas et al (1999) concluded that the myogenin gene influenced the growth of pigs and muscle mass.…”

AbstrAct:The study was designed to determine the associations between the Estrogen Receptor Gene (ESR -PvuII), Follicle Stimulating Hormone Gene (FSHB -HaeIII) and Myogenin Gene (MYOG -MspI) with traits characterizing the sow efficiency comprehensively. Concretely, the age of the first conception (AFC), service period (SP), insemination interval (InI), total number of piglets born (TNB), number of piglets born alive (NBA), number of piglets weaned (NW), lean meat content (LMC), backfat thickness (BFT) and average daily gain (ADG) were included in the study. Significant effects of ESR and FSHB genes on litter size (particularly in the second parity) and on reproduction traits were found in the investigated population. The influence of MYOG gene on reproduction traits was observed but there was no effect of this gene on litter size. None of the included genes had an effect on growth traits. The results outline the possible application of the above-mentioned genes in selection of Large White sows.

“…It was recognized as a distinct breed in 1964, and since 1996 it has been bred in a closed population. Within that population, genetic markers in association with reproduction traits (Horák et al 2004, Horák et al 2005 and gene polymorphisms associated with meat performance traits (Zrůstová et al 2009) have been studied, but until recently semen quality had not been evaluated. Therefore, the objective of this study, conducted over a test period from 2001 to 2009, was to examine the semen quality parameters of the Přeštice black-pied breed while taking into account the potential effects of collection month and boar age.…”

The objective of this study was to examine semen quality parameters for the Přeštice black-pied breed over a test period of 8 years while considering the potential effects of collection month and boar age. Ninety-nine ejaculates were collected using the gloved-hand technique from healthy and fertile mature boars from selected farms. Ejaculate volumes were relatively low because the boars were accustomed to natural mating. Sperm motility, sperm concentration, percentage of morphologically abnormal spermatozoa (MAS), and sperm motility after 24 h of storage in Androhep extender (dilution rate 1:1.5) were assessed. Significant differences were found in sperm concentration and MAS rate in relation to collection months and boar age in the monitored years (P<0.05). A tendency for MAS to increase with monitored years was observed. Significant differences in sperm motility and motility after 24 h of storage were only observed in relation to collection months (P<0.05). Results of this study detected effects due to collection month and boar age on boar semen quality during the monitored years.Keywords: boar, sperm quality parameters, Přeštice black-pied pig Zusammmenfassung Qualität des Eberspermas des Prešticer Schwarzbunten Schweins (Kurzmitteilung)Ziel dieser Studie war es, die Spermaqualität von Ebern des Prešticer Schwarzbunten Schweins über einen Zeitraum von acht Jahren zu analysieren. Neunundneunzig Ejakulate wurden mittels Handschuhtechnik von gesunden und fruchtbaren Ebern gewonnen. Das Ejakulatvolumen war relativ gering, weil die Eber an natürliche Paarung gewohnt waren. Bewertet wurden die Beweglichkeit der Spermien, die Spermakonzentration und der Prozentsatz der morphologisch abnormalen Spermatozoen (MAS) sowie die Beweglichkeit der Spermien nach 24 Stunden im Spermaverdünner Androhep (Verdünnung 1:1.5). Im Beobachtungszeitraum wurden signifikante Unterschiede (P<0.05) in der Spermakonzentration und im MAS-Anteil in Beziehung zu den Entnahmemonaten und dem Eberalter festgestellt. In laufe der Jahre wurde eine steigende Zahl von MAS im Ebersperma des Prešticer Schwarzbunten Schweins beobachtet. Signifikante Unterschiede (P<0.05) bei der Beweglichkeit der Spermien und der Beweglichkeit der Spermien nach 24 Stunden wurden nur in Beziehung zu den Entnahmemonaten beobachtet. Die Studie zeigt, dass im Beobachtungszeitraum die Spermaqualität vom Entnahmemonat und dem Eberalter beeinflusst wurde. Archiv Tierzucht 54 (2011) 4, 374-380, ISSN 0003-9438

“…Muscle fibre formation takes place during embryonic development in mammals and is controlled by the MyoD gene family, which consists of four genes, MyoD1 (MYF3), myogenin (MYOG or MYF4), MYF5 and MYF6 (MRF4) (Horák et al, 2004;Zhang et al, 2007;Ujan et al, 2011). The expression of the MYF5 and MYOD1 (MYF3) genes plays a fundamental role during myoblast proliferation, while the expression of the MYOG (MYF4) and the MYF6 (MRF4) genes is linked to the differentiation and maturation of myofibres (Stupka et al, 2012).…”

SUMMARYThe aim of this study was to analyse the associations between polymorphism in porcine myogenin gene (MYF4) and economically important traits in relation to the carcass and meat quality of pigs. The genomic DNA samples were taken from in total 180 crossbreeds (Large White x Landrace). The detection of polymorphism in MYF4 gene were performed in order to evaluate its effect on back fat thickness, proportion of valuable meat parts, MLT area and proportion of thigh. The genotyping of analysed individuals was carried out by means PCR-RFLP method and restriction endonuclease MspI. The allele frequencies were as follows: A 0.75 and B 0.25. A prevalence of AA genotype (59%) compared to AB (33%) and BB genotypes (8%) were detected in analysed crossbreed population. The observed average value of heterozygosity (0.33) and positive value of the Wright's F IS index (0.12) similarly reflected the higher proportion of homozygous genotype in populations. The effect of MYF4 gene polymorphism on selected phenotypic traits has been tested using one-way ANOVA procedure. The statistical analysis showed only non-significant results. Due to the polygenic character of selected phenotypic traits the involvement of other candidate genes and increase of sample size could clarify the role of MYF4 gene in porcine carcass and meat quality regulation. The study, which is based on molecular variability of livestock genetic resources, is necessary for the genetic improvement and understanding of relations between markers and trait of interest.
