Research Due to successful genetic selection, nutrition, and management practices, the number of pigs born per sow per year continues to increase. However, research suggests that the number of intrauterine growth retarded pigs, or those born < 1 kg BW, increases with increasing litter size. These ‘fall-back pigs’ have been shown to have decreased ADG and G:F throughout production compared to littermates heavier at birth, resulting in lighter slaughter weights and/or increased days to slaughter. My research project will focus on identifying how these pigs differ biologically and physiologically, and how to best manage them to maximize their contribution to the financial success of the pig farm in a welfare-friendly manner.
