1 st WorkshopXIII International Feed Technology Symposium318EFFECT OF A COMMERCIAL ESSENTIAL OIL ANDPROBIOTIC ON GROWTH PROMOTION IN BROILERCHICKENSTatjana Savković 1 , Marija Jokanović 21 Institute for Food Technology, University of Novi Sad, Bulevar cara Lazara 1, 21000Novi Sad, Serbia2 Faculty of Technology, University of Novi Sad, Bulevar cara Lazara 1, 21000 NoviSad, SerbiaABSTRACTThe concern about possible antibiotic residues and disease resistance has led toinvestigation of alternative feed additives in animal production. Today, among otheralternative for antibiotics, as growth promoters, in animal feed are both essential oils,and probiotics.An experiment was conducted to determine the responses of broiler chickens tocommercial blend of essential oils, or probiotics in feed. Trial involved day-old chickensof Ross 308 hybrid line assigned to 3 groups, namely, C- control, O- trial group (feddiets supplemented with essential oil extracts) and P- trial group (fed diet supplementedwith probiotics). The following production and performance parameters of broilers werestudied: daily gain, feed intake and feed conversion efficiency.Daily bodyweight gain was lowest for the control group. At the end of the trail the bodyweight of chickens fed supplemented diets was improved for 13% and 9% for theexperimental group O and P, respectively. Birds from the experimental group O and Phad lower feed intake for a kilo of weight gain in relation to control group.Key words: broiler meat, essential oil, probiotics, growth performancesINTRODUCTIONFeeding strategy is the management factor which is most actively used as a qualitycontrol tool in the production of meat and in relation to improvement and/or control ofperformance, animal welfare, safety, nutritional value, and eating and technologicalquality 1 . A number of feed additives have been widely used in the poultry industry forseveral decades. The manipulation of gut functions and microbial habitat of domesticanimals with feed additives has been recognized as an important tool for improvinggrowth performance and feed efficiency 3 .Modern trend in poultry production are going toward expelling synthetic medicines frombreeding. The ban on use of antibiotics as feed additives has led to investigation ofalternative feed additives in animal production. The effective replacement for theantibiotics should have a significant and sustainable beneficial impact on animalproduction and health, be proven safe for both animal and human population, be easy toapply and store and provide a substantial return on investment 13 . Aromatic plants andtheir extracts have received increasing attention as potential alternatives to growth
