This study compared the effects of giving three different types of feed (Yeast, palm
kernel cake, chicken manure) with different levels of concentrations (0.004g/L,
0.008g/L and 0.012g/L) on the growth survival and reproductive performance
(offspring production, life span, pre oviposition, oviposition, post ovipostion, egg
produced per female and production time of egg) of rotifer Brachionus plicatilis. Each
feeding treatment were tested on triplicates and was carried out for 10 days, the
growth, survival and reproduction performance (e.g offspring production) were
evaluated to assess the responses of Brachionus plicatilis to different types of feed
with different levels of concentrations. Rotifer had shown highest growth and survival
when fed with 0.0012g/L yeast (126.45 ± 84.53 ind mL-1) and (5.99 ± 7.053 ind mL-
1) were not significantly affected by diet used (P > 0.05). While highest offspring
production recorded when fed with 0.008g/L chicken manure (1.844 ± 0.01
egg/female) showed significantly different among all the treatment (P < 0.05). Rotifer
had produced comparable growth, survival and reproduction when fed with yeast,
palm kernel cake and chicken manure as single diet with different level of
concentrations. This indicates that, different types of feed and manipulations of
concentration is effective strategy to replace microalgae in rotifer culture.
