Physiological status of newborn calves of Holstein breed

The study of blood and intestinal microbiocenosis of neonatal calves allows assessing the viability and planning a set of preventive measures aimed at maintaining their health. For this purpose, morphological and biochemical parameters of blood and the composition of intestinal microflora of twenty new-born calves of Holstein breed from the farm located in Vladimir Region were studied. Before the feeding with colostrum, erythrocyte content in calves was 6.62 ± 0.49 × 1012 / L, hemoglobin 94.9 ± 7.4g / L, hematocrit 28.5 ± 2.5 %, MCV 43.2 ± 3.7 fL , MCH 13.3 ± 1.0pg, MCHC 332.4 ± 10.8 g / L. The concentration of leukocytes reached 13.84 ± 4.51 × 109 / L, of which 11.35% of monocytes, 43.0 % of lymphocytes,45.65 % of granulocytes. The range of platelet content (150-288) × 109 / L, thrombokrit 0.783 ±0.058. The total protein level was 62.5 ± 2.4 g / L and the relative hyperalbuminemia and bilirubinemia were typical for newborns. The glucose content is 3.54 ± 0.26 mM / L, the urea was2...
