The radical transformations that took place in agriculture, namely, in the livestock sector, led to enhancement in the poultry area. At the same time, informing the population on proper and natural nutrition boosted the level of breeding and consumption of broilers, rabbits, quails by all social categories. Currently, it is well known and accepted that natural remedies, namely of plant origin, are used for enhancing the adaptive properties, and reducing the negative consequences of stress in animals in different breeding conditions. According to scientific data, in birds under intensive growth, the most affected organ is liver. In this paper are presented the study results of the impact of a local biologically active remedy –BioR, obtained from Spirulina platensis, on health and especially on liver marker parameters - alkaline phosphatase and its fractions. Our research was conducted on 3 groups of quails, 80 birds each, at the end of their laying cycle, intended to be placed for recondition period. The drug was administered twice, intramuscular, to quails in the experimental group: at the beginning of the study and after approximately 10 days, in doses of 0,5 ml/head, and to the second experimental group, the drug was administered only once, at the beginning of the study, using the same dose of 0,5 ml/head. Birds from the control group were administered saline at a dose of 0,5 ml/head. Quails were monitored and examined during the whole study. For laboratory investigation, blood was collected from five birds each group, at the beginning, and at the end of the study. We would like to mention that the cyanobacterial remedy didn`t cause side effects or deviations in adult quails health. The tested remedy showed anti-stress and adaptive capacities, confirmed by lower body temperature and respiration values during the study. It has been shown that total alkaline phosphatase in the control group maintained the same level, while in the experimental groups, increased by 1,3 times compared to the control group. The liver thermostable fraction of alkaline phosphatase in the groups treated with BioR increased by 22,6-25,8% compared to the control group. In this context, the thermolabile fraction of the investigated index increased by 1,5-1,7 times compared to the control group. These are good results, showing the improvement of liver function, confirmed as well through the bio productive indices: body weight at the end of the study, numerical evolution of eggs, and quail meat quality.
