Potency of Green Cincau Leaves (Premna oblogifolia merr) Juice as Prebiotics and its Effect on Laying Hen Performances

Abstract

This study investigated the potency of green cincau leaves (Premna oblongifolia merr) juice as prebiotics end its effect on laying performances (feed intake, egg weight, feed conversion and hen day production) based on pH and digestive viscosity. The potency of green cincau leaves juice as prebiotic was tested. The result showed that green cincau leaves juice was effectively support growth of Lactic Acid Bacteria (LAB) with 4.3 x 10 2 CFU.g-1 samples but did not support the growth of Escherichia coli. The effect of green cincau leaves juice on laying performances was examined. Two hundred fifty 56-wk-old Hisex Brown layers received different diets namely 0, 5, 7.5, 10 and 12.5 ml of green cincau leaves juice added in the basal feed. The method used in this study was experiment based on Completely Randomized Design and followed by Duncan's Multiple test if significant effect occurs. The result showed that increase level of P. oblongifolia merr in feed did not significantly affect (P>0.05) feed intake, egg weight, feed conversion and hen day production.

Evaluating the Prebiotic Potential of Lepidium Sativum Seed Mucilage as a Nutraceutical Ingredient

“…Prebiotics are naturally present in various fruits, and vegetables [12,13]. As earlier reported, dietary polyphenols and there by-products from microbial degradation can stimulate particular bacterial populations present in the human gut [14].…”

“…The estimation of total and reducing sugar was done at both 0 and 6 h [22]. The percentage hydrolysis of the mucilage was estimated as the reducing sugar released and the total sugar content of the sample as below: For enzymatic hydrolysis α-amylase, 2 units mL -1 was prepared in sodium phosphate buffer (20 mM) adjusted to pH 6.9 using 6.7 mM of sodium chloride [23]. The sample was made as 1% (w/v) of mucilage dissolved in the buffer.…”
