This experiment was conducted to evaluate the nutritional value of
rosella seed, as a protein source, with and without enzyme (xylam 500)
on the performance, carcass yields and blood serum chemistry. One
hundred and ninety six, seven day old unsexed broiler chicks, chobb
strain, were used. Chicks were divided into seven groups of 28 chicks in
each and randomly assigned to treatment diets (A, B, C, D, E, F and H),
each treatment has 4 replicates. The first group A, fed on the control diet
used, groups B, C, and D fed on diets containing 5.0, 10.0 and 15.0%
rosella seed respectively, diet E, F and H fed on diet containing 5, 10,
15% rosella seed supplemented with enzyme respectively. Diets were
formulated to meet the requirements of broiler chicks according to NRC
(1994). Experimental diets were fed for 6 weeks. Experimental
parameters covered growth performance, slaughter and carcass values,
.serum metabolite, serum electrolyte and economical appraisal
Results showed no significant differences on the performance (weight
gain, feed intake, and feed conversion ratio and mortality rate) of chicks
fed on diets containing graded levels of rosella seeds with or without
enzyme. Although the supplementation of diets with enzyme improved
the performance of chicks. Result also showed no significant different
due to the inclusion of rosella seed or enzyme supplementation on
8
dressing percent, non carcass components commercial cuts and their
.separable meat quality
Result for serum metabolite, electrolyte and enzyme activities showed
significant difference in serum cholesterol and level of AST and enzyme
activity for chicks fed on control group while other values (total protein,
uric acid, Ca and ALT) observed no significant difference on among all
.tested groups
Economically rosella seeds can be included in broiler diets as plant
.(protein source up to 15%, supplemented with enzyme (xylam 500 |
