Diseases of the Veterinary Academy of the Lithuanian University of Health Sciences,

The aim of the research is to evaluate the postsurgical health condition of cows with left abomasal displacement (LDA) based on the blood serum biochemical indices. The research has been performed at a Lithuanian cattle farm having 600 dairy cows in 2007–2014. The research included in total 30 cows diagnosed with LDA during the clinical trial. For the purpose of control, 25 clinically healthy cows were selected based on the analogy principle. All the cows with LDA have un-dergone surgical treatment according to omentopexia. For the ketosis prevention, cows were given 0.300 kg of monopropylenglycol for 14 days after surgical correc-tion. For the purpose of biochemical testing, blood samples were collected from v. coccigea right before the surgery (Day 0), and subsequently seven days (Day 7), fourteen days (Day 14), and twenty-one days (Day 21) after the surgery. Blood serum was tested for the following parameters: calcium (Ca), phosphorus (P), magnesium (Mg), aspartataminotranspherase (AST), albumines (Alb), beta-hy-droxybutyrates (BHB), glucose concentration. Cows with LDA were observed to develop ketosis and hepatic lesions after surgical correction. Cows with LDA dem
