Degree of leukochimerism with calf age in Angus‐crossbred twin sets

Animal Genetics, 2023
AbstractTwinning in cattle is infrequent and usually undesired. It can result in an increased occurrence of abortion and dystocia, reduced calf survival and a high likelihood of freemartinism in mixed‐sex twins. Twin gestations are also commonly associated with the formation of placental vascular anastomoses (PVA) between twins.

Calf muscle-tendon properties and postural balance in old age [PDF]

Journal of Applied Physiology, 2006
We tested the hypothesis that compromised postural balance in older subjects is associated with changes in calf muscle-tendon physiological and mechanical properties. Trial duration and center of pressure (COP) displacements were measured in 24 younger (aged 24 ± 1 yr), 10 middle-aged (aged 46 ± 1 yr), and 36 older (aged 68 ± 1 yr) healthy subjects ...
