The aim at resealed was to study the influence of Chlorella suspension, sodium sulfate, chromium chloride and citrate on the physiological blood indices and nonspecific resistance of female rabbits during the period from copulation to the lactation peak. The number of erythrocytes, hemoglobin concentration, the aminotransferases activity, phagocytic activity of neutrophils, lysozyme and bactericidal activity of rabbitdams’ blood serum at introduction of Chlorella suspension, sodium sulfate, citrate and chromium chloride into the ration were determined. Researches were conducted on silver breed rabbits’ females, 110–114 days age, weighing 3.7–3.9 kg divided into five groups (one control and four experimental) 12 females each, selected on the basis of analogues principle. Control group rabbits were fed enough balanced granulated mixed fodder with free access to water. The 1st experimental group, except for mixed fodder, starting from the first research day received 90–110 ml of Chlorella suspension with water. The second experimental group’s animals were fed mixed fodder similarly to I experimental group’s schemes and drink, except for Chlorella, sodium sulfate in an amount of 40.0 mg/kg body weight or 0.15–0.17 g S per day. Females of the third experimental group received mixed fodder and water according to II group’s scheme with extra drinking Chromium as CrCl₃ х 6Н₂О, in the amount of 28–32 mg Cr per day at the rate of 7.6 mg/kg of body weight. Animals of the fourth experimental group received mixed fodder and water according to the II group’s schemes with additional introduction into the water of Chromium citrate obtained by using nanotechnology at the rate of 2.2 mg Cr/kg body weight or 8–12 mg Cr per day. Researched established that in the blood of II, III and IV research groups’ rabbits that additionally consumed sodium sulphate, chloride and chromium citrate, the number of erythrocytes, hemoglobin and total protein concentration, and activity of alanine aminotransferase were credibly higher on the 67 day of the study compared to the control group. Introduction to the diet of II, III and IV groups’ rabbits of mineral supplementation resulted in high immunological reactivity of organism with the increase of phagocytic activity of neutrophils, lysozyme and bactericidal activity level in the blood compared with animals of the control group.
