Extract

Alterations of foetal development in utero can affect the structure and physiology of the adult offspring, a process known as “foetal programming” (Barker, 1994). Results from the first phase of this study indicated that offspring from mature ewes offered a restricted energy intake in early pregnancy were heavier at birth and had improved survival rates to weaning (Muñoz et al., 2006). The aim of the second phase of the study was to determine the effects of plane of ewe nutrition in early and mid pregnancy on carcass characteristics of male offspring and on reproductive performance and concentrations of the adiposity indicator, leptin, in female offspring, post-weaning.
