Extract

Achieving adequate feed intakes by sows, and particularly gilts, in lactation can often be a problem under intensive farrowing-house conditions. It has been shown that sow feed intake during lactation can significantly affect subsequent reproductive efficiency such as remating interval, pregnancy rate and embryo survival (Einarsson and Rojkittikhun, 1993). There are many nutritional, environmental and physiological factors that influence the sow’s appetite during lactation. The physical form of the diet (wet or dry) has also been shown to affect feed intake as sows ate 12 % more feed given as a wet mash compare with dry form (O’Grady and Lynch, 1978; Genest and Dallaire 1995). The growth of the piglets during the first 2 weeks of lactation depends entirely on the milk supply of the mother. As this has been shown to be influenced by the level of feed intake (Koketsu et al., 1996), factors controlling feed intake during lactation should determine the rate and efficiency of piglet growth. The aim of this study was to investigate the effect of three different forms of diet on lactation feed intake of gilts and growth performance of their piglets.
