The objective of the present study was to investigate nutritional and metabolic status in Simmental cows during early and mid-lactation. Fifteen early lactating cows and 15 mid lactating cows were chosen for the investigation. Blood samples were collected to measure beta-hydroxybutyrate (BHB), nonesterified fatty acids (NEFA), triglycerides (TG), glucose and the activity of aspartate transaminase (AST). Early lactation as compared to mid lactating cows were found to have significantly higher (P<0.05) blood serum concentrations of NEFA, BHB and AST and lower blood serum concentrations of glucose (P<0.05) and TG (P>0.05). Significantly negative correlations were observed between BHB and glucose (P<0.01), BHB and TG (P<0.05), NEFA and glucose (P<0.05). Significantly positive correlations were observed between NEFA and BHB (P<0.05), NEFA and AST (P<0.05), glucose and TG (P<0.01). The results suggest that these parameters can serve as useful indicators of the nutritional and metabolic status of dairy cows during lactation.

Parturient paresis and subclinical hypocalcemia are frequent metabolic disorders in dairy cows postpartum. The aim of this study was to determine the effect of postpartum partial milking in the first two milkings on blood serum calcium concentration in dairy cows. Twenty multiparous Holstein dairy cows were randomized into two groups. Cows of group 1 (n = 10) were partially milked at the first and second milking postpartum. Cows of group 2 (n = 10) were completely milked. Blood samples were collected from all animals 5&ndash;7 days before calving, within 30 min after calving, and 4, 8, 12, 16, 20, 24, 28, and 32 h after calving for determination of serum calcium (Ca), phosphorus (P), and magnesium (Mg) concentrations. Colostrum production was registered and sampled in the first and second milking. Concentration of Ca in colostrum was determined by atomic absorption spectrophotometry. Serum Ca and P concentrations decreased in both groups after parturition (P &lt; 0.05) and remained low during 32 h postpartum with no difference observed between groups (P &gt; 0.05). Serum concentrations of Mg were stable in all samples and no statistical difference was observed between groups (P &gt; 0.05). Colostrum production was higher in completely milked cows only in the first postpartum milking (P &lt; 0.05), but there was no difference between groups at the second milking. Total Ca secretion in colostrum was higher in the complete milking group at the first and second postpartum milking. Colostrum Ca secretion increased at the second milking with respect to the first one in both groups (P &lt; 0.05). There was no correlation between serum Ca and colostrum Ca (P &gt; 0.05). In this study, the partial milking of colostrum in the first and second milking postpartum did not prevent subclinical hypocalcemia in dairy cows. &nbsp;

An emission spectrometric method of analysis is described, in which trace quantities of copper, iron, aluminum, barium, manganese, nickel, cesium, tin, strontium, chromium, zinc, lead, molybdenum, and cadmium were determined in blood serum. The sample preparation, starting with 2.0 ml of blood serum, is discussed in detail. The source of excitation was a 10 A dc arc. Quantitation was achieved with a direct reading emission spectrometer. The metal concentration, in micrograms per 100 ml of blood serum, was calculated from the experimental data by means of a computer.
