Current Trends with Enzymes Applications in Industrial Broilers Production

Abstract

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.
