Effects of the Bior Remedy on the Trypsin-Antitrypsin System and the Productivity Indexes in Broilers
Abstract
Today the increasingly spreading interdiction to use hormones, growth stimulators with antibiotics, and genetically modified products for maintaining the health and productivity of animals and poultry compels forage and drug producers and owners of animals to search for other strategies for the optimization of the performance characteristics, protection of environment, improvement of product quality, and for ensuring the best general condition of animals possible. Thus, this study aims at determining the influence of BioR remedy obtained from Spirulina platensis on broilers. The experiment involved 4 lots of 30 broilers each, from the 2nd day of life. 3 experimental lots received intramuscular injections of BioR in different doses, 2 times in a row: on the 2nd and 21st day, and the 3rd lot was injected for the 3rd time as well – on the 34th day after eclosion, while the broilers from the control lot were injected 0,15 and, respectively, 0,5 ml serum. For the biochemical test blood was collected from 5 broilers 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 correction properties of the trypsin-antitrypsin system – results which were also confirmed by higher bioproductive indexes in experimental lots
