This experiment was conducted at Naresuan University, Phitsanuloke, Thailand to evaluate the potential of using 5 mixtures of essential oil extracted from clove, peppermint and orange peel in weaner pig diets for nutrient digestibility evaluation using 35 days old crossbred Duroc x (landrace x Large White). Twenty four pigs consisting of 12 males and females were housed in individual cages and randomly distributed into 6 groups of 4 pigs each in a Completely Randomized Design. The pigs in each group were randomly fed with one of 6 diets as follows: diet 1 was a basal diet (control, diet) containing corn-soybean meal. Diet 2, 3, 4, 5 and 6 was a basal diet supplemented with a mixture of clove oil: peppermint oil:orange peel oil at the ratios 1:1:1, 1:2:1, 1:2:2, 2:1:1, 1:2:2, and 2:2:1, respectively at 5 ml/kg diet. Experimental period consisted of 3 days for diet adjustment followed by 3 days of total feces collection for nutrient analysis. The results showed that digestibility coefficient of dry matter, crude protein, gross energy, crude fiber, ether extract and ash of the pigs fed diets 1, 3, 4, 5 and 6 were not significantly different among treatments. However, the pigs fed diet supplemented with 5 ml/kg diet of mixture of clove oil: peppermint oil: orange peel oil at the ratio 1:2:1 had the highest nutrient digestibility coefficient. A mixture of essential oil extracted from clove, peppermint and orange peel at the ratio 1:2:1 has a potential for use as feed additive in weaner pig diets.
