Abstract:
Even though, there is a high potential of rice bran as a feed ingredient in broiler
feeds, low digestibility is setback the use of it. Thus, this study was carried out to
investigate the effect of Protease and Lipase enzymes on digestibility of fat and
protein of rice bran based broiler feeds. A total of 320, day-old-broiler chicks were
selected and fed with experimental diets. Excreta and feed samples were analyzed
and performances of bird were evaluated. The ether extraction method was used to
analyze the amount of fat in feeds and excreta. Amount of protein analyzed by using
Kjeldahl method. Data were analyzed using two way ANOVA procedure with
Genstat software. Results revealed that, enzymes were not much effective in
improving the performance in digesting fat and protein of broilers fed with rice bran
based feed. Overall result of digestibility had a significant difference (P<0.05) with
rice bran levels. Also digestibility of fat increased gradually with the level of rice
bran. However, there was no significant difference (p>0.05) of digestibility in fat
and protein with the enzymes. It can be concluded that, there is no effect on
digestibility of crude fat and crude protein with use of the particular enzymes with
rice bran based feeds in broiler. Digestibility of crude protein is higher in 20% rice
bran based broiler feeds and digestibility of crude fat gradually increased with the
levels of rice bran.
