Objective. To summarize the recent studies on effect of conjugated linoleic acid (CLA) on hepatic steatosis and hepatic and adipose lipid metabolism highlighting the potential regulatory mechanisms.Methods. Sixty-four published experiments were summarized in whichtrans-10,cis-12 CLA was fed either alone or in combination with other CLA isomers to mice, rats, hamsters, and humans were compared.Summary and Conclusions. Dietarytrans-10,cis-12 CLA induces a severe hepatic steatosis in mice with a more muted response in other species. Regardless of species, when hepatic steatosis was present, a concurrent decrease in body adiposity was observed, suggesting that hepatic lipid accumulation is a result of uptake of mobilized fatty acids (FA) from adipose tissue and the liver's inability to sufficiently increase FA oxidation and export of synthesized triglycerides. The potential role of liver FA composition, insulin secretion and sensitivity, adipokine, and inflammatory responses are discussed as potential mechanisms behind CLA-induced hepatic steatosis.

This study was conducted to evaluate feeding periods of dietary conjugated linoleic acid (CLA) supplementation on growth performance, nutrient digestibility, blood profiles, and meat quality in finishing pigs. A total of 150 finishing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 83.13 ± 1.91 kg were randomly allocated into one of three treatments (10 pens per treatment, five pigs per pen) based on their BW. Dietary treatments consisted of supplementing the basal diet with 1.0% CLA during 2, 3, and 4 wk prior to finishing. Pigs fed CLA diets 2 wk before finishing had a higher overall average daily gain (ADG) and gain-to-feed ratio (G/F) than those fed CLA diets 4 wk before finishing (P < 0.05). In the whole experiment, pigs fed CLA diets 2 wk before finishing had a higher serum low-density lipoprotein (LDL) than those fed CLA diets 3 and 4 wk before finishing. However, pigs that received CLA diets 4 wk before finishing had higher triglyceride levels (P < 0.05). Feeding 1% CLA diets 4 wk before finishing improved meat color and firmness. Taken together, feeding 1% CLA diet 4 wk before finishing increased ADG, G/F, and serum LDL, but reduced serum triglyceride.

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.
