Effects of the remedy BioR drug on the Trypsin ‐ Antitrypsin system in broiler chicks

Abstract

This work presents the results of a scientific research carried out in poultry factory conditions with the purpose of delineating the impact of BioR on the trypsin‐ antitrypsin system in broiler chicks. The study involved 150 broilers divided into 5 grouprs with 30 broilers each. The young broilers from the experimental groups 1‐4 received intramuscular BioR injections twice as follows: on the 9th day ‐ 0,3‐ 0,6ml/head and on the 21st day – 0,4‐1,0ml/head. The broilers in the control group were injected physiological serum respectively 0,4 and 0,6 ml/head. The study showed that the BioR product obtained from Spirulina platensis through modern technologies and injected into broiler chicks starting with the 9th day of life is very well tolerated both generally and locally and improves the trypsin‐antitrypsin system in broilers.
