of antibiotic (flavomycin), probiotic (primalac), prebiotic (Biolex-MB)
and mixture of probiotic and prebiotic (primalac plus Biolex-MB) as dietary
growth promoter on growth performance, carcasscharacteristics and hematological
indices of broiler chickens. Three hundred day old Ross 308 broilers were
equally distributed into 30 floor pens and reared for 42 day. A basal
diet was formulated covering the recommendations of NRC (1994) for starter
(0-21 days) and grower (22-42 days) periods and considered as control
diet. Four tested diets were formulated by supplemented the basal control
diet with antibiotic (flavomycin), probiotic (primalac), prebiotic (Biolex-MB)
and mixture of primalac plus Biolex-MB, respectively. Six replicates were
used for each treatment. The results of present study showed that all
growth promoters used was improved growth indices of Ross 308 broilers.
The highest significant (p<0.05) values of carcass and thigh were recorded
for broilers fed diet supplemented with flavomycin. The highest (p>0.05)
value of breast was recorded for broilers fed the diet supplemented with
primalac, meanwhile the lower value were showed for birds fed either diet
or diet supplemented with Biolex-MB. The percent of carcass and cuts followed
the same trend. Hematological parameter including cholesterol was recorded
the highest (p>0.05) values groups fed the diets either control or
supplemented with flavomycin, meanwhile the lower value was showed for
bird fed diet supplemented primalac plus Biolex-MB. Triglycerides and
very low density lipoprotein cholesterol (VLDL) were recorded the highest
concentration for bird fed both control and diet supplemented with flavomycin
groups while least concentration was found for bird fed diet supplemented
with primalac. The results of present study revealed that probiotic and
prebiotic as growth promoters can use as alternatives non-antibiotic feed
additives to their free harmful side effects on the consumers and to improve
broiler chickens growth indices.]]>Ammerman, E., C. Quarles and P.V. Twining,198968167167Anderson, D.B., V.J. McCracken, R.I. Aminov, J.M. Simpson, R.I. Mackie, M.W.A. Verstegen and H.R.
