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 102 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.Keywords: feed additives, laying hens performance, prebiotic, Premna  oblongifolia merr juice.

Abstract

This research aimed to examine the effects of fish oil and tomato powder supplementation on egg quality of Mojosari ducks. A total of one hundred and forty Mojosari ducks (consisted of 20 male and 120 female ducks), aged at 40 weeks old, were randomly allotted into 20 flocks (each flock consisted of 1 male and 6 female ducks). Method used was experiment in a Completely Randomized Design with 5 treatments and 4 replications. Dietary treatments used were T0: basal diet (control), T1: basal diet + 1% FO, T2: basal diet + 2% FO, T3: basal diet + 1% FO + 1% TP; T4: basal diet + 2% FO + 1% TP. Data were analyzed using one-way analysis of variance (ANOVA). Result showed that supplementation of fish oil and tomato powder did not significantly affect (P>0.05) external egg quality (egg shape index, shell surface area, shell thickness and specific gravity). Dietary treatments also had no significant effect (P>0.05) on internal egg quality (albumen volume, yolk volume, albumen index, yolk index and Haugh unit). It is concluded that there was no detrimental effect of fish oil and tomato powder supplementation in Mojosari ducks diet on external and internal egg quality.Keywords: antioxidant, Haugh unit, laying duck, omega-3 fatty acids, poultry.
