This experiment was conducted
to investigate the effect of form of diets with different levels of
biozyme enzyme on broilers performance. 800 Arbor Acres strain chickens
were used in a factorial arrangement 2×3 with 2 form of diets (pellet
and mash) and 3 levels of biozyme (0, 0.75 and 1.5 kg/ton) in a randomized
completely design with 6 treatments and 3 replicates in each treatment
and 45 birds/replicates. The weight gain (WG), feed intake (FI) and
feed conversion ratio (FCR) were measured weekly from week 1-6. Carcass
components were recorded at the end of trial (day 42). The WG were significantly
(P< 0.05) greater in broiler fed pellet diets than comparable groups.
The birds fed diet containing 0.75 kg/ton biozyme had greater WG (56.31
vs. 54.77 and 54.57 gram) and better FCR (1.7 vs. 1.79 and 1.84) than
birds fed diets containing the two others levels. The weight of breast,
thigh, abdominal fat and liver were significantly (P< 0.05) greater in
broilers fed 0.75 kg/ton Biozyme and pellet diet. Heart weight in broilers
fed pellet diets were significantly (P< 0.05) heavier than the broilers
fed mash diets (9.56 vs. 8.056 gram). On, the other hand, Right ventricle
to Total ventricle ratio was not affected by form of diet. It is concluded
that the performance and carcass characteristics were improved in pellet
diets.]]>
