The effect of designer fat as to changes in triacylglycerol structure in dietary fat on nutrient digestibility, nitrogen retention, and fatty acid profile of plasma, erythrocyte membranes, liver adipose tissue and skeletal muscle were examined in four groups of post-weaning piglets. The test fats added by 10 percent to diets were: R1 regiospecific structured fats with decanoic acid mainly located in the sn-1/3 positions and a long-chain fatty acid from rapeseed oil in the sn-2 position, R2 similar fat subjected to chemical randomization, R3 physical mixture of tridecanoin and rapeseed oil, and R4 rapeseed oil. The piglets were weaned at 28 days of age and after one week of adaptation faeces and urine were collected quantitavely during three periods each of 7 days, in which the piglets were kept in metabolism cages for measurement of nutrient and energy digestibility and protein retention
