The palatability of different cereals was studied in 2 two-way choice (preference) experiments using pigs of 56 d of age and 17 kg of BW. The diets containing extruded rice, extruded naked oats, or naked oats were preferred by pigs to the reference diet. However, the reference diet was preferred to the diets containing 150, 300, and 600 g·kg−1 of cooked long-grain rice, oats, or cooked oats, 300 and 600 g·kg−1 of extruded wheat, wheat, corn, sorghum, or unhulled short grain rice, and 600 g·kg−1 of thick rolled oats, extruded corn, rye, extruded barley, micronized naked oats, barley, cassava, or biscuit meal. Therefore, cereal type, inclusion rate, and diet form affect feed preference in pigs and using cereals with greater preference values may contribute to the formulation of more palatable feeds, which enhance feed intake of piglets at critical stages such as weaning time.
