| Özet |
| Antibiotics have been added to poultry feed to improve growth performance, to stabilize intestinal microflora and to prevent infection by specific pathogenic microorganisms. However, concerns about antimicrobial resistance have existed for nearly as long, and recent concerns regarding the prevalence of antibiotic-resistant infections in humans have raised the controversy to new heights (REVINGTON, 2002). For these reasons antibiotic growth promoters for poultry diets have been banned for use in the European Union and pressure from consumer groups and major poultry buyers has threatened their removal from diets in the US. Therefore, studies on alternate products that can result in promotion of growth, improved feed utilization, and maintenance of gut health are taking place (ZHANG et al., 2005). For this reason, the natural material propolis is being investigated. Propolis (bee glue) is a natural resinous hive product collected by bees from plants, particularly from flowers and leaf buds. Bees use propolis to cover the inside of the hive and mix it with bees' wax when building combs to protect the colony and larvae from pathogenic microorganisms (KRELL, 1996). Propolis contains a variety of chemical compounds such as polyphenols (flavonoid aglycones, phenolic acids and their esters, phenolic aldehydes, alcohols, and ketones), terpenoids, steroids, amino acids and inorganic compounds (DIMOV et al., 1991; MORENO et al., 2000). |
