LAJU PERTUMBUHAN POPULASI Brachionus plicatilis O. F. Muller DENGAN PEMBERIAN KOTORAN AYAM KAMPUNG (Gallus varius L.) DAN AYAM BROILER (Gallus demostica L.) PADA MEDIA KOMBINASI PUPUK UREA DAN TSP
Abstract: The relationship between
growth rate of Brachionus plicatilis O. F. Muller population and feeding that contain
addition of local
chicken manure (Gallus
varius L.) and
broiler chicken’s (Gallus domestica L.) in urea and triple
superphosphat (TSP) was conducted on September 2012 in Animal Systematic Laboratory,
Biology Department, Mathematics
and Sains Faculty,
Sumatera Utara University. This
research used complete randomized design (CRD) with 4 treatments chicken
manure, that is M1 (300 mg/2 L local), M2 (400 mg/2 L local), M3 (300 mg/2 L
broiler) and M4 (400/2 L broiler), with 6 times repeated and 8 times
observation during 16 days. The result showed
that the growth rate of B. plicatilis the highest on medium M4 is 8.492 indx2x10-3xday-1
and have the lowest on
the medium M1 is 8.386 indx2x10-3xday-1. These
showed that using broiler chicken’s manure is better than local chicken’s
manure.
