PROBIOTICS INFLUENCE UPON THE MAIN TECHNICOECONOMIC PARAMETERS IN BROILER BREEDING

Abstract

The purpose of this research was to establish the effect of Biomin IMBO probiotic upon broilers chicken vaccinated against Newcastle disease. Probiotic effect was assessed by emphasis of the most important zoo-economic changes induced by these bioadditive. Group C (control) and E2 (experimental 2) were fed with standard combined diet; group E1 and E3 were fed with standard combined diet and Biomin IMBO added to the starter diet at 1 kg/tonne, and in grower diet at 0.5 kg/tonne. Birds from group E2 and E3 were vaccinated against Newcastle disease. All broilers were periodically weighted and at the control slaughtering the carcasses were cut in commercial pieces and: average daily gain, specific feed intake and slaughtering efficiency were quantified. Results analysis suggest that the highest values of weig-ht were registered in experimental group E3 (probiotic + vaccination), while C, E1 and E2 have variability two and half fold higher. Also, the obtained results proved that positive effect of Biomin IMBO on summation of average daily gain and specific intake was 13.49%.
