Influence of pregnancy stage on blood biochemical parameters in Alpine goats

The aim of this paper was to determine the influence of pregnancy stage on biochemical parameters in the blood of Alpine goats. The research included 21 French Alpine goats who were divided per 7 in the group according stage of pregnancy (up to 3 months, from 3 to 4 months, and more than 4 months). Feeding of goats was with a mixture of grains and meadow hay. In the blood of goats were determined concentrations of the biochemical parameters (urea, glucose, total proteins, albumins, globulins, cholesterol, HDL-cholesterol, LDL- cholesterol, triglycerides, NEFA- non esterified fatty acids and creatinine as well as enzyme activity: CK-creatine kinase, GGT-γ- glutamyl transferase and ALP- alkaline phosphatase). As pregnancy progressed a significant decrease in the content of total protein (from 77.73 to 65.87 g/L), albumin (from 31.70 to 28.18 g/L) and globulin (from 46.03 to 37.69 g/L) as well as activity of GGT (from 41.12 to 29.04 U/L) and an increase concentrations of urea (from 2.29 to 3.11 mmol/L), triglycerides (from 0.27 to 0.50 mmol/L) and NEFA (from 0.03 to 0.06 mmol/L) were determined. Comparing determined biochemical parameters with reference values in the blood of goats during various stages of pregnancy, significant differences were not evident, except concentration of urea and albumin, which were at the lower limit and concentration of globulin, which were at the upper limit of reference values for goats. Mentioned biochemical parameters changes in the blood of goat in late pregnancy (urea and albumin) indicate a lack of protein in the feed and the need to include stages of pregnancy and breed as important factors in quality monitoring of herd.
