KEBERADAAN BAKTERI DAN PERKEMBANGAN CAECUM AKIBAT PENAMBAHAN INULIN DARI UMBI DAHLIA (DAHLIA VARIABILIS) PADA AYAM KAMPUNG PERSILANGAN PERIODE STARTER
ABSTRACT: The purpose of the
research was to study the effects of feeding inulin derived from dahlia tuber
powder and extract on the existence of bacteria and growth of caecum in
crossbred native chicken starter period. Experimental animals were 280 birds of
unsex crossbred native chicken and source of inulin derived from dahlia tuber
in the form of powders and extract which were started to be fed on day 22. The
present experiment was assigned in completely randomized design with 7
treatments and 4 replications (10 birds each). Feeding treatments were as
follows: T0 (basal diet/BD), T1 (BD +0.4% powder of dahlia tuber), T2 (BD +0.8%
powder of dahlia tuber), T3 (BD +1.2% powder of dahlia tuber), T4 (BD +0.39%
extract of dahlia tuber), T5 (BD +0.78% extract of dahlia tuber) and T6 (BD
+1.17% extract of dahlia tuber). Parameter measured were lactic acid bacteria
(LAB), Escherichia coli, pH of caecum, height dan weight of caecum. Data were
subjected to ANOVA and followed by Duncan. The results indicated that feeding
inulin derived from dahlia tuber powder form at 0.8% (T2) and extract form at
1.17% (T6) could increase lactic acid bacteria population, low pH and
Escherichia coli, increased height and weight of caecum. In conclusion, feeding
inulin derived from dahlia tuber powder at 0.8% (T2) and extract formed at
1.17% (T6) could increase lactic acid bacteria, but on the contrary, it
decreased intestinal pH and Escherichia coli population as well as increased
height and weight of caecum.
