This research is important in order to establish the true beneficial effect of probiotics directly on microbiomе and indirectly on the traits associated with the intensity of growth, as well as the welfare of the animal's organism. The aim of the study is to evaluate the Influences of the probiotic ZOOVIT on grow intensity performances and blood composition in lambs. The study was conducted in the sheep farm of the Agricultural Institute - Stara Zagora. 60 lambs were included, weaned from their mothers on the 5th day of their birth, and divided equally into 2 groups: experimental and control. The animals from the experimental group taken 4 g of ZOOVIT probiotic per day with milk replacer. Blood analyses are derived on automated haematology instrument Mindray Auto Hematology Analyzer BC-2800 Vet and automated biochemical analyzer MNCHIP Chemistry Analyzer Celercare® cV5. The consummated feed and residual were weighted every day and the lambs every 3 days by mechanical scales. Descriptive statistics and t-tests for comparison the values of some biochemical and intensity of growth parameters was obtained by using software product SPSS 13.0. Lambs in experimental group had larger average body weights, greater daily weight gain, increased average daily intake and a better feed efficiency, compared to control group. Animals in experimental group had average body weight of 21.42 kg and daily average gain 0.357 gr, control group had average body weight of 19.68 kg and daily average gain 0.328 gr. Differences between groups on grow intensity performances is statistically significant (P < 0.05). Total protein in the blood in the experimental group is higher than in control 64.18 g/L and 58.60 g/L respectively, from here comes and statistically significant (P < 0.05) higher concentration of albumin and globulin in blood in the experimental group. It is noticeable higher levels of red blood cells and the hemoglobin in the experimental group RBC - 10.93 x 1012/L, HGB - 93.85 g/L compared to RBC - 10.09 x 1012/L, HGB - 90.57 g/L with the control group, differences between groups are statistically significant (P < 0.05). We established higher mortality rate of 3.33% in the control group than the experimental. There are positive overall benefits from using probiotic ZOOVIT as supplement for the development of lamb organism. [ABSTRACT FROM AUTHOR] |
