ANALYSIS OF THE INFLUENCE OF A NUTRACEUTICAL SUPPLEMENT WITH PROBIOTIC EFFECTS ON HEALTH INDEX AND PRODUCTIVE PERFORMANCE IN BROILER CHICKEN

摘要

This study was motivated by the fact that the available data on the effects of probiotics and nutraceuticals concerning the health and the productive performance indices in avian species are still controversial. The research consisted in evaluating the influence of BioLactorom nutraceutical product on the main haematological, clinical and biometric indices in Broiler chickens (Ross 308), divided in a control group (n=20) and an experimental group (n=20). According to the manufacturer's instructions, 1 ml of BioLactorom/l water was administered to the chickens in the experimental group in the first 3 days of life, respectively in days 17-19, to reduce the stress generated by manipulation and batching. The chicks were clinically monitored throughout the evaluation, and haematological and microbiological examinations (cultural, on simple agar and McConkey agar, respectively bacterioscopic exam) were performed. All the data obtained emphasized the beneficial effects of BioLactorom, in improving the growth factor, the immunity and the balance of the intestinal flora, and also in reducing the costs of vaccines and other drug products.
