SAPU-SAPU FISH (Hyposarcus pardalis) AS A SINGLE PROTEIN SOURCE FOR LAYING MOJOSARI DUCKS
Abstract: The present study
was conducted to evaluate the optimum level of dietary inclusion and the form
of feeding sapu-sapu fish (SSF) as a single protein source for feed components
of small holder Mojosari duck farming. A total of 180 twenty four wk-old laying
ducks were fed with two forms (sun-dried and ground-fresh) and three levels of
SSF (10, 20 and 30%) from 24 to 32 wk of age. Experimental diets were
formulated containing 105.1; 141.5 and 177.9 g/kg crude protein and 3078; 3065
and 3052 kcal metabolizable energy (ME) /kg diet. Production performance and
egg quality were measured. The form of SSF had a significant effect
(P<0.0001) on feed intake, egg production, feed conversion, egg mass and egg
number except final body weight. No significant effects (P>0.05) were found
on all of the performance parameters measured due to feeding levels of SSF
except feed intake and final body weight. The interaction of form and feeding
level was significant (P<0.05) on egg and body weights. Low performance and
egg quality were observed in the birds fed a diet containing the dried SSF. It
can be suggested that local ducks required 20% SSF as a single protein source
for maximum egg production (41.2%) and total egg number per wk (3.1
eggs/bird/wk) during 8 wk of rearing period. Egg quality can be improved by
feeding the fresh SSF. However, due to be sufficiently better processing
technique, the dried SSF would be potential to replace the common fish for
laying ducks.
