Honey is a thick, sweet, syrupy substance, the product of the honey-bee, Apis mellifera L., obtained from the collected fruit juices and other, processed in the stomach of bees and is a pure product with no additives of any other substance. The paper present physical-chemical analysis for the following parameters, performed on 20 honey samples: sugar content, sucrose content, moisture content, free acidity, electrical conductivity, mineral content, the content of HMF and content of matter insoluble in water. As important indicators of the environment, this paper emphasises the analyses on the presents of antibiotic residues in two types of honey. The importance of establishing these indicators is to protect nature, which is the basis of agricultural development in the Republic of Srpska. The work suggests that the described bee region presents qualitative honey produced by using the natural resources of a designated area as an economic sector for the survival and development of those parts of the Republic of Srpska.

Background: This study was conducted to analyse the effect of different enzymes and selenium on production performance and slaughter parameters of Ross (308) broilers production. Method: There were four groups in this experiment, two of them were control and the two test groups. All groups had the same number of one-day-old chickens (20250), moved in the same day. 100 chickens were selected randomly for future analyses. The chickens in the control group were fed with the standard commercial diet which contained crude protein (22.04%, 18.55%, 17.89%) and metabolic energy including selenium (11.99 MJ/kg, 12.64 MJ/kg, 12.79 MJ/kg) for starter, grower and finisher phases respectively. The basal diet was supplemented with: HiPhos - 6 phytase, WX - endo-1,4- betaxylanase, VP-endo-1,3(4)- beta-glucanase and ProAct - serine protease. The experimental group also used organic selenium. Results: Production performance and carcass parameters were not statistically different among treatment groups. Only mortality was decreased in one of the experimental groups (p less than 0.004). Whereas, the use of enzymes and selenium did no effect on the production performance and carcass parameters. The results indicate reduced feed cost of broilers diet with the use of enzymes as feed components. Result from presented work can be considered as complementary contribution in in broiler production.
