Abstract

Digestibility of Nutrient and Performance of Kacang Goats which are Given Fermented Oil Palm Fronds Extract

Highlights

Oil palm fronds contain high lignin, namely 30.18% (Febrina et al, 2016a, b) so that their use as feed is very limited but oil palm fronds can be used as antioxidants (Imsya et al, 2013); anti-microbial (Febrina et al, 2018, 2020); and feed (Suyitman et al, 2020)
One part of plant polyphenols are tannins, which can precipitate protein (Hagerman, 2012), bind minerals and reduce the bioavailability of minerals (Naumann et al, 2017).Tannins are grouped into 2 groups,namely condensed tannins (CT) and hydrolyzable tannins (HT) (Patra and Saxena, 2010)
The addition of Quercus pyrenaica leaves which contain hydrolyzed tannins inhibits the digestion of cattle (Doce et al, 2013), this is because more protein is bound to hydrolyzed tannins than condensed tannins ( Jayanegara et al, 2015)

Summary

Introduction

Oil palm fronds contain high lignin, namely 30.18% (Febrina et al, 2016a, b) so that their use as feed is very limited but oil palm fronds can be used as antioxidants (Imsya et al, 2013); anti-microbial (Febrina et al, 2018, 2020); and feed (Suyitman et al, 2020). The lignin content in oil palm fronds can be lowered through processing biologically, physically, chemically and by a combination. Febrina et al (2020) reported that fermented oil palm fronds with 10% of poultry manure reduced the lignin content by 33.93% (decreased from 30.18% to 19.94%). One part of plant polyphenols are tannins, which can precipitate protein (Hagerman, 2012), bind minerals and reduce the bioavailability of minerals (Naumann et al, 2017).Tannins are grouped into 2 groups,namely condensed tannins (CT) and hydrolyzable tannins (HT) (Patra and Saxena, 2010). The addition of Quercus pyrenaica leaves which contain hydrolyzed tannins inhibits the digestion of cattle (Doce et al, 2013), this is because more protein is bound to hydrolyzed tannins than condensed tannins ( Jayanegara et al, 2015).
