Embryonic mortality rate in pigs, sheep and goats ranges around 30%. It occurs mainly
during the first month of pregnancy and mostly before implantation. In pigs, a second less …

In contrast to human embryos, there are very few studies published on the frequency of
chromosomal aneuploidy in farm animals. The objectives of this study were to apply a three …

Smaller litters and an increased rate of stillbirth were observed among the offspring of a boar
carrying a reciprocal translocation, rcp (14; 15)(q29; q24). The translocation appeared to be …
