Antiviral activity of trifuzol for the broiler at poultry farm

Abstract

The birds diseases in the modern poultry industry have a negative impact on economic development of poultry business, as it causes poor assimilation of food and consequently, slow weight gain in broilers and reduce the number and quality of eggs from hens. Thus the economic costs of this are usually much higher than from mortality [1,6,8,9].

The aim of research was to test the efficiency of the trifuzol vaccinations against viral diseases in growing broilers.

Methods and results. Production tests of trifuzol impact on the effectiveness of vaccination against viral diseases and broiler production indexes when growing broilers were performed on the experimental group, which did not receive trifuzol (20.000 heads) And a control group that received 1% trifuzol solution 0.5 ml per 10 kg body weight for 3 days in a row for 7–9 days birth poultry (19.000 heads).

The test systems of the BioShek company were used for the detection of antibodies to the ICC and ICC ELISA, and set for hemagglutination delay reaction (Russia) was used for the detection of antibodies to Newcastle virus.

Conclusions. It was established that the level of protective antibodies during vaccination IBD matches the basic norm, however, the vaccination index (VI) in the control group was 1.5 times higher. The average antibody titer to the NH virus when using trifuzol was 5 log₂, and group immunity was 87.5% which corresponds to the basic norms of vaccination in NH. The European efficiency factor in the experiment was 5% higher than in the control group.
