Introduction: Large within-litter variation in pig foetal weight may be associated with placental efficiency. Integrin receptors, including AVB6, are present at the attachment site between the foetal and uterine epithelium and may affect the efficiency of attachment. It is hypothesised that the expression of integrin receptors would differ between tissues supplying small foetuses compared to normal-sized littermates. This study compared the distribution and quantity of integri...
