Influence of phytogenic feed additive aviance on the growth of chicken broilers

Abstract

In the year 2003-2004 reearch work was carried out in the Research Laboratory of Biological Diversity and Technologies of Vilnius Pedagogical University and on poultry farm "Vilniaus paukštynas", aiming to investigate an influence of Aviance, the feed additive of plant origin on the growth of Ross breed chicken broilers. The above-mentioned feed additive Aviance stimulated the growth of chicken broilers. It was observed that bodyweight of male chickens at the age of 42 days increased by 6.64 % and weight of female chickens increased 2.18 % in comparison with the control group. Average daily weight gain was improved in the trial group at all periods of growth and at 42 days was 4.48 % better compared with the control group. Feed conversion had also improved in the trial group and was 1.03 % better than in the control group. Parameters of blood were also improved in the trial group. Total amount of albumen and amount of nucleic acids in the blood of the chicken broilers in the trial group had increased. The researched phytogenic feed additive Aviance had a positive influence on the growth of chicken broilers
