|
An
experiment on ROSS 308 male broilers was conducted to
evaluate probiotic (Primalac), prebiotic (Fermacto) and
butyric acid glycerides (Baby C4) on broiler
performance and serum composition. Seven hundred and four
day-old broilers were randomly distributed in a 2×2×2
factorial arrangement with two levels of probiotic,
prebiotic and butyric acid glycerides. Eight treatments with
four replicates each with 22 birds per pen were used.
Three-way interaction between dietary treatments were
observed for final body weight (P<0.05), feed intake
(P<0.01) and feed conversion ratio (P<0.01) in the
experiment. Body weight, feed intake and feed conversion
ratio between supplementary treatments and control group
were significantly different (P<0.01).
Three-way interaction
between dietary treatments were observed for total
cholesterol (P<0.05), LDL (P<0.01), cholesterol/HDL ratio
and HDL/LDL ratio (P<0.01) in the experiment. Total
cholesterol concentration, LDL, HDL/LDL ratio and
cholesterol/HDL ratio between supplementary treatments and
control group were significantly different (P<0.05 and
P<0.01). Serum
triglyceride, HDL and VLDL cholesterol concentrations
were not significantly
different among dietary
treatment when compared to control group (P>0.05). In
conclusion, dietary supplementation improved the body
weight, feed conversion ratio, HDL/LDL ratio and decreased
feed intake, total cholesterol, LDL cholesterol and
cholesterol/HDL ratio in the serum of broiler chickens.
Key
words: Probiotic, prebiotic, butyric acid glycerides,
