Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh level energi dalam pakan terhadap produktivitas pejantan buras. Penelitian ini merupakan penelitian lapang menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan diulang sebanyak 4 kali. Pejantan buras yang digunakan sebanyak 16 ekor umur 80 minggu. Analisis statisik menunjukkan tingkat energi memberikan pengaruh sangat nyata (p<0.01) terhadap konsumsi pakan, konsumsi energi, pertambahan bobot badan; nyata (p<0.05) terhadap produksi semen dan tidak nyata (p>0.05) terhadap mortalitas. Rataan konsumsi pakan yang didapatkan pada penelitian ini berkisar antara 86-96g/ekor, konsumsi energi 255.1-263.9kcal/ekor, PBB 70-105g/ekor dan produksi semen 0.55-1.08ml. Produktivitas terbaik didapatkan pada pakan perlakuan dengan energi metabolis 2850kcal/kg.

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.
