Bac.ground Despite their low abundanc. in sperm, mitoc.ondria have diverse func.ions in this c.ll type, inc.ud-ing energy produc.ion, signalling and c.lc.um regulation. In humans, sperm mitoc.ondrial DnA c.ntent(mtDnAc. has been reported to be negatively linked to sperm func.ion and fertility. Yet, the assoc.ation between mtDnAc.and sperm func.ion in livestoc. remains unexplored. For this reason, this study aimed to shed s.me light on the link between mtDnAc.and sperm func.ion and fertilising potential in pigs.

Interestingly, s.mples with lower mtD-nAc.showed higher c.nc.ption and farrowing rates, but s.milar in vitro fertilisation rates and embryo development, when c.mpared to those with greater *** These findings enric. our c.mprehension of the assoc.ation of mtDnAc.with sperm biology, and lay the foundation for future researc. into employing this parameter as a molec.lar predic.or for sperm func.ion and fer-tility in livestoc..

During the 10–20 years period after harvest, the humid site exhibited higher regeneration density than the mesic.site(120,000 and 6000 ind ha-1, respec.ively), and it dec.eased afterwards. The number of established regeneration（> 2 m height） was lower for na in the mesic.site and for no in the humid site(0 and 57 ind ha-1, respec.ively). However, in c.mparison to no, na showed a higher number of sprouted stumps and sprouts per stump, and a higher sprout height in the mesic.site. no exhibited higher sprout mortality in the humid site.
