Article Synopsis
- The study investigates differences in vitality between in vitro produced (IVP) and ex vivo derived bovine embryos, highlighting that IVP embryos tend to be less viable.
- Research focuses on how mitochondrial function relates to embryo development, which has not been extensively studied before.
- Findings reveal that embryo quality is influenced by environmental conditions and developmental timing, with higher-quality embryos showing distinct respiration patterns and optimal mitochondrial activity.
The widespread use of cryopreserved in vitro produced (IVP) bovine embryos is limited due to their low post-warming viability compared to their ex vivo derived counterparts. Therefore, the present study aimed to analyse in detail the consequences of cryopreservation (vitrification and slow freezing) on the bioenergetic profile of the embryo and its mitochondria. To accomplish that, day 7 IVP embryos were separated in a non-cryopreserved control group (fresh, n = 120, 12 replicates) or were either slow frozen (slow frozen, n = 60, 6 replicates) or vitrified (vitrified, n = 60, 6 replicates).

Medium to high heritabilities have been observed for some of the immune traits suggesting genetic variability of these phenotypes. Consideration of previously established genetic correlations between immune traits can be used to identify pleiotropic genetic markers.

However, the immune system is complex and the genetic foundation of the underlying components is not yet clarified. In the present study, we focused on 22 blood parameters of 1,144 Landrace (LR) and Large White (LW) piglets at the age of 6-7 weeks.
