In lactating sows and piglets grouped during the suckling period, performance problems have been identified and associated with disruption of suckling (Wattanakul, 1995). Cross-suckling and an increase in number of piglets at the udder have been recognized (Hatet, 1994). The aim of the study was to investigate the effect of these factors on the suckling patterns by manipulating cross-suckling and addition of piglets in individually housed sows.
