Choline chloride possible effect on the blood serum of cows

Abstract

In order to know choline chloride effect on blood serum‘s hydroxybutyrate (BHBA), glucose (GLU), insulin (INSUL), triglycerides (TG), cholesterol (T-CHO) concentration of dairy cows, we did research in one of Lithuania's milk farm. The research took place in the „X“ farm and Cathedral of non-infectious disease of LUHS in 2015. 40 cows were selected using analogical reasoning in their 3 or 4 lactation period. All cows 3 weeks before calving were divided into two groups – experimental (n=20) and control (n=20). Calving feeds of experimental cows were added with cholin supplement (dose – 100g/d) before 30 days. Control group cows were given its usual feeds according to the balanced diet ratio. The research results were assesed 21 d.p.p of following parametres: urea (BUN), triglycerides (TG) cholesterol (THO), insulin (INSUL) of cows who were fed with cholin supplement (100g/d). It was determined that urea’s concentration after 21 days from the beginning of the research increased from 2,92±0,04 mmol/l to 5,47±0,06 mmol/L of experimental group, while control group‘s were increased from 2,74± mmol/l to 6,02±0,1 mmol/L. Triglyceride level in the control group from the beginning to the end decreased by 0.036 ± 0.002 mmol /L, compared with the experimental group triglyceride level decreased from 0,306 ± 0,023 mmol/L to 0.281 ± 0,016 mmol/L. Insulin level in the experimental group from the beginning increased from 1.748 ± 0.023 μU/ml to 2,435 μU/ml, in the control group decreased from 3.245 ± 0.016 μU/ml to 2,993 ± 0.01 μU/ml. Beta-hydroxybutyrate in the experimental and control groups from the beginning increased equally by 0.87 mmol/L.
