Genetic marker technologies, such as marker-assisted selection, parentage identification,
and gene introgression can be applied to livestock selection programs. Highly saturated …

The introduction of foreign DNA into the genome of livestock and its stable integration into
the germ line has been a major technical advance in agriculture. Production of transgenic …

We investigated the effect of the estrogen receptor (ESR) gene on growth and reproductive
traits in four Large White-based commercial pig lines. A total of 9,015 litter records from …

The efficiency of marker-assisted introgression in backcross populations derived from inbred
lines was investigated by simulation. Background genotypes were simulated assuming that …

To compare the effect of different genes on litter size, we used PCR-RFLP to test the
genotypic frequencies of 5 genes related to litter size, ie ESR, FSHβ, PRL, PRLR and …

Three populations of Hereford cattle differing in inbreeding levels and genetic potential for
growth were genotyped for seven DNA polymorphisms. The populations were compared to …

Recent studies report a surprisingly high degree of marker-to-marker linkage disequilibrium
(LD) in ruminant livestock populations. This has important implications for QTL mapping and …

Transgenic animals are produced by introduction of 'foreign'deoxyribonucleic acid (DNA)
into preimplantation embryos. The foreign DNA is inserted into the genetic material and may …

Seventy-seven Large White× Meishan F2 crossbred gilts with prolactin receptor (PRLR)
genotype AA (n= 26), AB (n= 36) and BB (n= 15) were compared for teat number (FTm), age …

Abstract Analysis of the genetic variation of an endangered population is an important
component for the success of conservation. Animals from two local Romanian pig breeds …
