Influence of liquid probiotic inclusion as feed additives on lipid profiles and meat cholesterol content of commercial broiler chickens

Abstract

Abstract Due to consumer’s concern for food safety and the pathogenic bacterial resistance of antibiotics in humans, the usage of antibiotics as animal feed has been banned. The aims of this study was to investigate inclusion of liquid probiotic in drinking water on lipid profiles and meat cholesterol content of commercial chickens. Totally 100 chickens at the age of 28 d from growth study were selected for 20 chickens (5 birds per treatment) for further lipid profiles and meat cholesterol content study. Four treatment in this study was inclusion of liquid probiotics in the drinking water with different concentration (P1=control, P2= 1.0 %, P3= 1.5 % and P4= 2.0 % of probiotic in drinking water). The result of the study indicated that inclusion of liquid probiotic up to 2% did not significantly reduce the weight and percentage of abdominal fat and cholesterol in the breast meat broiler. However, inclusion of probiotics at the level of 1.5% was the best level indicated low cholesterol concentration and high value of iodine concentration in meat broilers. Based on the study, it was concluded that probiotics can be used as alternative feed additive to replace antibiotics as growth promoters up to 1.5% at the best.
