PROBIOTICS INFLUENCE UPON THE MAIN TECHNICOECONOMIC PARAMETERS IN BROILER BREEDING
Keywords:
broiler chicken, probiotic, average daily gain, specific feed intakeAbstract
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%.
