The article investigates the effect of Spirulina platensis on key aspects of the immune system and the level of morbidity in service dogs undergoing chronic stress. The aim of the work was a comprehensive assessment of the potential of this microalgae as a natural immunomodulator for optimizing the immune response and increasing resistance to diseases in animals whose work is associated with high physical and psychological stress. The study was conducted on 20 service dogs of the German Shepherd breed (aged 3-5 years), which were regularly exposed to stressful influences. The animals were divided into two groups: control and experimental. During the experiment, the indicators of humoral (IgA, IgM, IgG), cellular (number of T-, B-, O-lymphocytes, FAN) immunity and nonspecific resistance (lysozyme activity of blood serum) were monitored. The frequency and duration of acute respiratory diseases and gastrointestinal disorders were recorded separately. The results of the study demonstrated an increase in the experimental group of IgA (by 34.4%), IgM (by 26.47%) and IgG (by 25.55%) compared to the control group. Analysis of lymphocyte subpopulations revealed a significant increase in the absolute number of T-, B- and O-lymphocytes (by 25%, 25% and 25.58%, respectively). FAN was higher in the experimental group by 37.1%, and lysozyme activity of blood serum increased by 44.0%. Clinically, this was accompanied by a decrease in the frequency (by 66.7% for ARI and by 80% for SCI) and average duration (by 51.2% for ARI and by 61.5% for SCI) of diseases in the experimental group. The results obtained indicate a pronounced positive effect of Spirulina platensis on various components of the immune system of service dogs undergoing chronic stress. This justifies the prospect of using Spirulina platensis as an effective and safe functional feed additive to maintain health and increase resistance to diseases in service dogs, which is an important aspect of their professional activity.
