Alquremold Natural (AMN) for Growth Performance, Carcass Characteristics and Bacterial Growth Inhibition of Commercial Broilers

Abstract

An experiment was conducted with 648-day-old Cobb 500 broiler chicks to evaluate the effects of Alquermold natural (AMN) on overall growth performance, carcass characteristics and inhibition of enteric bacterial growth of commercial broilers. The birds were randomly assigned to four different treatments: T0 (Control), T1 (0.5 g/kg AMN), T2 (1.0 g/kg AMN) and T3 (1.0 g/kg Mold Inhibitor (MI)), respectively. They were reared for up to 28 days. At the end of experiment, the birds’ growth performances in terms of body weight (BW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), survival, and meat production characteristics were recorded and calculated. Weekly fecal sample collection and microbiological count were performed to determine the bacterial load, specifically Escherichia coli and anaerobic bacteria in the broiler feces. The results showed that birds receiving 1.0 g/kg AMN had significantly higher BW and BWG (p0.01) than the control, 0.5 g/kg AMN, and MI groups. The FI and FCR of broilers were comparable in all treatment groups. There were no significant (p > 0.05) changes in meat yield parameters such as dressing percentage, neck, shank, drumstick, breast meat, thigh meat, and wing meat. However, when compared to the other dietary treatments, the bacterial load (E. coli and anaerobic bacteria) was significantly lower in the birds fed 1.0 g/kg AMN. Based on the findings, it can be concluded that feeding AMN at a rate of 1.0 g/kg may be considered for improving growth performance, maximizing feed utilization, and inhibiting bacterial load in the intestine of commercial broiler chickens.
