Extract

Conjugated linoleic acid (CLA) is a mixture of geometrical and positional isomers of linoleic acid. Health-promoting properties of CLA, which include antioxidant, anti-obesity and anticarcinogenic activities, have been demonstrated in a wide range of animal models (Pariza et al., 2001). Recent studies indicated the CLA has a favorable effect on immune competence in nursery (Bassaganya-Riera et al., 2001) and weaned pigs (Corino et al., 2001). For this reason CLA may be useful in sow nutrition to increase CLA content in colostrum and milk (Bee, 2000). However CLA-fed animals displayed also significantly reduced body fat (Pariza et al., 2001) and this effect may be detrimental to reproductive efficiency in sows per se and for the effects on metabolic hormones as well. Moreover some CLA isomers has been reported to influence leptin gene expression (Houseknacht et al., 1998). The present study examined the effects of dietary supplement of CLA on serum leptin in lactating sows.
