Many feed additives are designed to secure animal’s health status and to optimize growth performance. Among others, antibiotics have been used as growth promoters for a number of years in intensive animal production systems. However, the increasing public concern over the production of food from animals has led to worries about the routine use of antibiotics in animal production. It is now feared that antibiotic residues could get into food for human consumption. The use of antibiotics as promoters of animal performance in the EU was banned by January 2006 (Øverland et al., 2003). Inborr (2000) has reported that with the aid of number of alternatives including probiotics, prebiotics (mainly oligosaccharides) and feed enzymes not only has the general health status of the poultry been maintained, but also the growth performance and feed efficiency improved.
The aim of our research project was to determine the effect of different prebiotics - mannanooligosccharides, fructooligosaccharides and enzymes on broiler chickens growth performance and meat sensory attributes. To realize this aim, we conducted two experiments: 1. Effects of enzymes RovabioTMExcel AP and prebiotics mannanoligosaccharides Agrimoss on broiler chickens body weight, feed conversion (kg feed/kg weight gain), mortality, breast and leg meat pH, breast fatty acids concentration and breast and leg meat sensory attributes. 400 broiler chickens were allocated to two groups and for 35 days were fed basal diet...
