Pengaruh pemberian suplemen probiotik yeast dengan level berbeda terhadap pertambahan bobot badan dan konversi pakan domba jantan

Abstract

This study aimed to determine the effect of yeast probiotics on body weight gain and feed conversion in rams. The research was carried out at the PT.. Pandu Bina Sejahtera located in Bojong Koneng, Babakan Madang District, Bogor Regency. The research used 12 Priangan rams, with an average age of 6-8 months and initially weight 11 – 14 kg. This research design used a Completely Randomized Design (CRD) using 3 feed treatments and 4 replications. The treatments applied were as follows: P0=Control (forage + concentrate with a ratio of 70:30% in dry matter), P1=Control + 1 yeast supplementation/head/day (1 gram of yeast), and P2=Control + 2 yeast supplementation / head / day (2 gram of yeast). The research parameters observed included body weight gain, feed consumption and feed conversion. Sheep weighing is carried out once a week. The data was analyzed using ANOVA and if the results were significant then the DMRT (Duncan's Multiple Range Test) test was carried out. Giving yeast supplements generally had an effect on body weight gain (P<.05) but had no effect on consumption value and feed conversion. The highest average body weight gain results were in treatment P3, followed by treatment P2 and the lowest was treatment P0. The conclusion of this research is yeast supplements of 2 g/day provides the most optimal body weight gain results.
