Abstract

Milk production in 5 single-housed Yorkshire sows was measured using the isotope dilution technique with D2O as a marker. Sows were in their third parity and litter size was 7-13 piglets. Piglets were enriched twice, at 4-5 (period 1) and at 16-18 (period 2) days of age. During the measurement periods nursing behaviour of sows with litters were recorded using a time lapse video. Piglet teat order was recorded by direct observation. The individual milk intake was significantly correlated with piglet LW (+), piglet growth (+) and teat pair number (-). Teat pair number was also correlated with piglet LW and growth (both negatively), but not with piglet birth weight. No significant correlations between sow milk yield and nursing frequency or length of nursing bouts were found. Nursing frequency decreased from period 1 to period 2 (30.5 and 26.3 per day, P
