Supplementation of probiotics play an important role on the growth performance of native chicken to achieve early market weight. It has been observed that there was a development of resistance by pathogenic bacteria against antibiotic mixtures used in the feed as growth promoters. The major concern in using antibiotics is presence of residues in the egg and meat. Probiotics are found to be an alternative to antibiotics to reduce the disease incidences and to improve feed efficiency.
Totally 100 numbers of day old Aseel cross chicks were selected and randomly divided into two groups of 50 chicks each. Chicks in control group (T1) were fed with commercially available feed without probiotic supplementation and chicks in treatment group (T2) were fed with probiotic supplemented commercial feed. Trial period was upto 10 weeks of age.
Fortnightly body weight and body weight gain were significantly (P<0.01) higher in treatment group (T2) compared to control group. Average daily weight gain and feed conversion ratio also highly (P<0.01) significant in treatment group.
