The research objective was studying the influ-ence of probiotic preparations "Vetom 1.1", "Vetom 3" and "Velez 6.59" on the organism of small cattle. Operating beginning in specified probiotics were "Vit 1.1" - Bacillus subtlis a strain of VKPM V 7092, "Vetom 3" - Bacillus licheniformis a strain of VKPM V 7048 and "Velez 6,59" - Lactobacillus plantarum a strain of VKPM V-2347 and Propionibacterium freudenreichii a strain of VKPM V-6561. The re-search was conducted in Novouzensky district of Saratov Region on the lambs of tsigaysky breed aged 1-3 months. The groups, 5 heads in each were created by the principle of analogs: 3 experi-mental and 1 control. The preparations applied to lambs orally 2 times a day in a dose 50 mg/kg, were previously dissolved in milk. During the re-search the account of clinical signs, conducted blood tests of lambs and the accounting of their gain was kept. The blood was taken from a jugular vein in pure test tubes with addition of 3-- 4 drops of 1 % of heparin solution. During the researches identical conditions of keeping and feeding of ani-mals were supported. It was established that probi-otics "Vetom 1.1", "Vetom 3" and "Velez 6.59" had positive effect on morphological composition of blood of small cattle of all experimental groups, making active protective properties of the organism. Also it is necessary to specify that average daily gain in the first experimental group (probiotic "Ve-tom 1.1") and the third experimental group (probi-otic "Velez 6.59") increased by 25 %, in the second (probiotic "Vetom 3") - for 37 % in comparison with animals of control, it testifies to positive influence of probiotics both on growth and on the development of lambs.
