title: Effect of seven hours intermittent suckling and flavour recognition on piglet performance.
abstract: A low feed intake during the first days after weaning is predisposing for weaning diarrhoea and weight loss. In this experiment we tried to increase the feed intake of the piglets after weaning by stimulating the solid feed intake during the last two weeks before weaning by separating them from the sows for 7 h/d. In addition, the effect of flavour recognition and the interaction of flavour recognition with intermittent suckling were tested. In two consecutive weaning rounds, sows were divided over two compartments with 7 to 10 sows each. They were assigned to one of four treatments in a two factorial design: control housing/control feed (n = 7); control housing/ flavoured feed (n = 8); intermittent suckling/control feed (n = 7); intermittent suckling/ flavoured feed (n = 9). After weaning, for each round 3 pens of 6 pigs were selected per treatment group. All these piglets received the same feed with the same flavour at the same concentration. Contrary to the expectations, intermittent suckling decreased the solid feed intake during the last two weeks before weaning. Flavour addition to the creep feed did not increase feed intake or other performance parameters before and after weaning, nor did it interact with intermittent suckling. Although after intermittent suckling pigs ate less creep feed before weaning, they did not perform worse after weaning. However, to increase feed intake after weaning, longer periods of separation might be necessary.
