Efektivitas Daun Jarak (Jatropha curcass Linn) Sebagai Anticacing Ascaridia galli dan Pengaruhnya terhadap Performa Ayam Lokal
Abstract: The present
experiment was aimed to identify the phytochemical of Jatropha curcas leave
extracted with water and methanol as an anthelmintic agent for Ascaridia galli,
and its effect on native chicken performance. In vitro study of anthelmintic
activity was conducted by counting the number of paralyzed worm dead-body of A.
galli during 18 hours in petri dish containing different levels of extract,
namely 0%, 1%, 2%, 3%, and 4% (w/v) and compared to the piperazine 0.5% (w/v).
Eightteen birds of naturally A. galli-infected native chicken were used for the
in vivo study. The treatments were 0%, 2%, 4%, 8%, and 16% of J. curcass leave
extract, and 10% of piperazine using a completely randomized block design with
6 treatments and 3 replications. Parameters observed were fecal worm egg count,
feed consumption, body weight gain, feed conversion ratio, and mortality. The
results showed that water- and methanol-extracted J. curcas leave had similar
composition of secondary metabolite compounds which is high in triterpenoid and
steroid contents, respectively. Percentage of paralyzed A. galli was higher (P
< 0.01) in water-extracted jatropha leaves. On the contrary, the dead-body
percentage was higher (P < 0.05) in the methanol-extracted than that in the
control group. In vivo study showed that leave meal significantly decreased (P
< 0.05) fecal worm egg count. The leaf meal at the level 16% tended to
increase feed consumption, body weight gain, and significantly decreased feed
conversion ratio. In conclusion, J. curcas leave meal have anthelmintic
activity to A. galli and could improve nutrient utilization of naturally A.
galli-infected native chicken by decreasing feed conversion ratio.
