Bioappraisal Of Different Non-Antibiotic Growth Enhancers Using Broilers

ABSTRACT

A sixty three (63) day experiment was carried out to bio-appraise different non-antibiotic growth

enhancers using one hundred and twenty day-old broiler chicks (DOC). The DOC were

randomly assigned to four treatments of 30 birds per group, each with three replications (10 birds

per replicate), in a completely randomized design (CRD). T1 served as the control (CT), whereas

T2, T3 and T4 had commercially procured ElRox (EX), PolaMix (PX) and MaxiGrowth (MX)

growth promoters incorporated at 400g/100kg, 500g/100kg and 600g/100kg respectively. Data

were collected weekly on body weight, body weight gain, daily

feed intake, feed conversion ratio, protein efficiency ratio and feed cost per Kg gain. Carcass

yields of the experimental groups were also evaluated at the end of the experiment. Biochemical

parameters of the bird were also determined at the end of the experiment. These were protein

profile, liver enzymes, bilirubin, lipid profile and serum arsenics. Results of this study showed

that the non-antibiotic growth enhancers used in the study had a significant (P
