Effects of the Bior Remedy on the Trypsin-Antitrypsin System and the Productivity Indexes in Broilers

摘要

Today the increasingly spreading interdiction to use hormones, growth stimulators withantibiotics, and genetically modified products for maintaining the health and productivity of animals and poultrycompels forage and drug producers and owners of animals to search for other strategies for the optimization ofthe performance characteristics, protection of environment, improvement of product quality, and for ensuring thebest general condition of animals possible. Thus, this study aims at determining the influence of BioR remedyobtained from Spirulina platensis on broilers.The experiment involved 4 lots of 30 broilers each, from the 2nd day of life. 3 experimental lotsreceived intramuscular injections of BioR in different doses, 2 times in a row: on the 2nd and 21st day, and the3rd lot was injected for the 3rd time as well on the 34th day after eclosion, while the broilers from the controllot were injected 0,15 and, respectively, 0,5 ml serum. For the biochemical test blood was collected from 5broilers on the 2nd day before injecting BioR and on the 43rd day before slaughter from 5 broilers from each lot.The biochemical study carried out on young broilers treated with BioR before slaughter has revealed correctionproperties of the trypsin-antitrypsin system results which were also confirmed by higher bioproductive indexesin experimental lots
