Abstract :
This study aims to determine the effect of giving rubber seed flour fermented
using tempeh yeast on the production performance of male quail. The research
method used a Completely Randomized Design (CRD) experimental method
using about 260 male quail aged 0-5 weeks. Divided into 4 treatment groups with
the level of giving fermented rubber seed flour using different tempeh yeast,
namely P0 = feed with the addition of 0% fermented rubber seed flour, P1 = feed
with the addition of 4% fermented rubber seed flour, P2 = feed with the addition
of fermented rubber seed flour as much as 8%, and P3 = feed with the addition of
12% fermented rubber seed flour. Each treatment was repeated 5 times so that 20
units were obtained with a total of 13 male quails per unit. Parameters observed
were feed consumption, body weight gain, feed conversion. The results of the
study concluded that the addition of fermented rubber seed flour to the ration had
a significant effect on feed conversion but had no significant effect on feed
consumption and body weight gain. Provision of fermented rubber seeds at the
8% level had the best number with feed consumption, body weight gain and feed
conversion, respectively, namely 496.47g/head, 144.71 g/head and 3.41.
