Effect of feeding diets containing an antibiotic, or a probiotic on growth and pathogenic intestinal bacteria in domestic fowls
Abstract: A4-wks study was conducted to determine the effect of diets containing an antibiotic (Zinc bactracin), or aprobiotic (Effective Microorganisms ), on performance and urease Pathogenic Intestinal Bacteria of Inshas chicks a (local Egyptian chicken strain) .The experimental design consisted of six experimental groups: control and 5 dietary treatments as follows; (T1) Basal diet ( control ), (T2) basal diet + EM (2.5 ml/kg diet ), (T3) Basal diet + EM 5.0ml/kg diet ), (T4) Basal diet + EM (7.5 ml/kg diet ), (T5) Basal diet + EM (10.0 ml/kg diet) and (T6) Basal diet + Zinc bactracin (500 mg/kg). Feeding treatment was started at 4 wks of age and lasted at 41 wks of age. Characteristic investigations were including: Live body weight; Body weight gain; feed consumption; efficiency of feed utilization and Bacteria Enumeration (Aerobic plate count (x106/g), E coli, Salmonella, Staphylococci and Coccidia ovum). Feeding diets containing the probiotic were significantly (P < 0.01) increasing the average daily gain during the experimental period compared to the control. This increase was partially accounted with increased feed intake. During the experimental period, feeding the diet containing probiotic significantly reduce the counts of total viable bacteria (P < 0.01) E coli, salmonella, staphylococci and Coccidia ovum in caecum compared with untreated control diets. Our study indicating that, dietary probiotic decreases pathogenic intestinal bacteria of chicks and this may be beneficial for improving animal health and growth performance.
