The intragastric pH was recorded every four seconds for a period of 23 hours. The Warmblood horses were assigned randomly to receive hay ad libitum (H group); 1.5 kg hay/100 kg BW/day and 1 kg concentrate/100 kg BW/ day (C group) or protocol C plus 75 g pectin-lecithin supplement/100 kg BW/day (P group). The horses were adapted to each diet for 13 days. The 23-hour median pH value for protocol H (2.69) was significantly lower compared to protocol C (.5) and P (.33)(p  lt; 0.05). The horses in protocol P had a significant higher percentage (30.1 %) of 23-hour intragastric pH values ≥ 3 than in protocol C (6.2 %) or in protocol H (25. %) (p  lt; 0.05).  a0005-9366
