A note on the growth of early-weaned Hampshire piglets

Abstract

SUMMARYThe appetite and growth of individually-fed, weaned Hampshire and Saddleback piglets and of Hampshire and Large White × Landrace piglets were compared in three experiments from 14 to 49, 28 to 55 and 21 to 45 days of age. There was a reduced rate of growth in the Hampshire piglets, which was not found to be related to any need of Hampshire piglets for a higher quality diet. Neither was there any reduction in the efficiency with which Hampshire piglets used ingested nutrients, nor a differential rate of deposition of any body component. Hampshire piglets ate less food than Saddleback or Large White × Landrace piglets and this reduced appetite was largely accounted for by the lower body size.
