|Abstract||Differences in growth performance of piglets during lactation might be related to differences in insulin sensitivity. Therefore glucose metabolism may be affected differently in low performing (LP) and high performing pigs (HP) at weaning when feeding either a slowly digestible starch (SDS) or rapidly digestible starch (RDS). In a 2×2 factorial block design 30 LP pigs and 30 HP pigs equal
in birth weight were housed in one of four respiration chambers and fed diets containing either RDS or SDS. In the first week feed was available ad libitum. In the second week feed supply was restricted to 65% of the observed feed intake in the first week. Energy and nitrogen balances were calculated for both weeks. Results were used to calculate incremental efficiencies of gross energy
(GE) and metabolised energy (ME) for growth. Incremental efficiency of GE for growth was higher when feeding RDS compared with SDS, particularly so in LP pigs (diet×pig type; P=0.05). The incremental efficiency of ME for growth tended to be lower with SDS compared with RDS (74.1 vs 75.6; P=0.05) but was not affected by growth retardation during lactation.
