Relationship between phenols and in vitro digestibility of six legume feeding shrubs

Abstract

Abstract: Abstract: Several legume shrubs in Yunnan province were analyzed to understand the dynamic changes in phenol content during different growth stages. The results showed that TET content (42.9 g/kg)changed from the wilting stage of Leucaena glauca to the flowering stage of Indigofera galegoides DC(123.6 g/kg); SPH content changed from the nutritional stage of L. glauca (11.6 g/kg) to the seed set stage (58.7 g/kg). The TEPH content of each growth stage was followed by a change in the ranges of 109.1-173.3 g/kg, 104.1-169.2 g/kg, 103.7-153.0 g/kg, and 86.6-155.6 g/kg. The phenol contents of I. galegoides was the highest while those of D. triangulare and I. amblyantha were lower than the others. The relative contents of four phenols were TEPT>TECT>TET>SPH. There was a strong and positive correlation among TECT, TET, and TEPT(P<0.01), but there was no significant negative correlation with SPH(P>0.05). IVOMD and IVDMD had a strong and negative correlation with TEPT, TECT, and TET. The absolute correlation value was higher than 0.7.
