Kajian Penambahan Ragi Tape pada Pakan terhadap Konsumsi, Pertambahan Bobot Badan, Rasio Konversi Pakan, dan Mortalitas Tikus (Rattus norvegicus)
Abstract: An experiment was
conducted to examine the effect of different levels of tape yeast addition into
rations on Rattus norvegicus performance, such as feed consumption, body weight
gain, feed conversion ratio and mortality. The experimental design used was a factorial
completely randomized design 2 x 4, the first factor was sex (male and female
rats), and the second factor was different levels of tape yeast added into
rations (0% as R1, 0.5% as R2, 1% as R3 and 1.5% as R4). The results showed
that the interaction between sex and yeast addition had significant effect on
feed consumption and body weight gain (P < 0.05), but the effect was not
significant on feed conversion ratio and mortality. Yeast addition in male-rat
rations significantly reduced feed consumption, but did not affect body weight
gain. In female rats, the addition of yeast in the rations increased body
weight gain. Increasing levels of tape yeast in the rations improved the body
weight gain and feed conversion ratio, especially for female rats (P <
0.05). There was no single rat died during the experimental period. Rats fed
ration containing 1.5% yeast showed better feed consumption, weight gain, and
feed conversion ratio compared to rats given other rations.
