The prevalence and factors contributing to the incidence of neonatal gastroenteritis in newborn calves

Abstract

The results of monitoring the situation of neonatal gastroenteritis of calves are presented for four farms in the north-western districts of the Saratov region, during the period of mass calving. The incidence of neonatal gastroenteritis of calves was 11.92 - 16.36%. Factors contributing to the morbidity of newborn calves with neonatal gastroenteritis - complications of pregnancy, depending on the gestational period, subclinical ketosis (27.65%), osteodystrophy (15.71%), liver and kidney diseases (10.59%) have been established. In 30.23% of calves with NG, a large number of under-oxidized metabolic products and impaired liver and kidney function were observed. In patients with severe neonatal gastroenteritis, the following indicators were at a low level: alkaline reserve (40.8 ± 1.3 vol% CO2), glucose content (2.86± 0.12 mmol/L). In the central part of the liver, large-drop granular dystrophy is observed with the preservation of the structure of hepatocytes.
