Interaction of Se supplementation with sulphur and magnesium in blood plasma were studied in dairy cows. Cows were divided into three groups: (1) control, no treatment; (2) cows injected intramuscularly 21–10 d prior to parturition with 45 mg Se and 2040 IU of vitamin E; (3) cows intraruminally administered with two 30-g pellets containing 10% elemental Se 2 mo prior to expected calving. There were no significant effects of Se supplementation on the plasma levels of sulphur and magnesium. Key words: Selenium, sulphur, magnesium, blood, cattle

Holstein Cows

Eight Holstein cows were fed a diet supplemented with selenium at a subtoxic level (2.37 mg kg−1 dry matter), or the same diet without selenium supplementation (0.31 mg kg−1 dry matter), for 276 d of lactation. Copper-65, a stable isotope, was administered intravenously after 14 d of adaptation to the diets, and samples of milk, blood and liver were obtained at intervals throughout the trial. The effect of selenium supplementation on copper metabolism of the cows was evaluated by determining concentrations of copper in plasma, milk and liver, by determining the activities of ferroxidase in plasma and superoxide dismutase in erythrocytes and by determining the pattern of dilution of the copper-65 tracer in plasma, milk and liver. No effect of selenium supplementation on any of the parameters of copper metabolism was observed. It was concluded that an interaction between copper and selenium did not occur under the conditions imposed in this study. Key words: Copper, selenium, interaction, dairy cows, copper stable isotope

AbstractIntroduction: The transition period is the most challenging time for dairy cattle, which is characterised not only by negative energy balance but also by fatty tissue mobilisation.Material and Methods: The efficiency of energy pathways, β-oxidation in WBC and glycolysis in RBC (based on deoxyglucose transmembrane transport) were estimated. Insulin in blood plasma was determined using ELISA.Results: After calving and up to one month after delivery, a significant drop in blood plasma level was noticed, simultaneously with a rise in β-oxidation from 18.93 ±3.64 to 30.32 ±5.28 pmol/min/mg protein in WBC. A strong negative correlation between these two indices (r = −0.68) was found. During the period of transition to lactation an increase in glucose cross-membrane transportation from 41.44 ±4.92 to 50.49 ±6.41 μmol/h/g Hb was observed. A strong positive correlation between glucose transportation in RBC and β-oxidation in WBC (r = 0.71) was noticed. These data are in agreement with results of studies on dairy cows using liver slices from dairy cows in late pregnancy and different stages of lactation, in which changes in gene expression were analysed.Conclusion: It seems that measuring fatty acids oxidation and glycolysis using isolated blood cells may be an adequate and relatively simple method for energy state analysis to estimate the state of dairy cow metabolism and animal health.

Premature rupture of membranes is the most common complication of pregnancy. The incidence of premature rupture of membranes in pregnancy ranged from 6% to 10%, and 20% of these cases occur before 37 weeks gestation. The incidence of premature rupture of membranes in Indonesia ranges from 4.5% to 7.6% of all pregnancies. This research was conducted to determine the cross-sectional differences in the blood plasma levels of vitamin C in term pregnancy premature rupture of membranes with blood plasma levels of vitamin C in term pregnancy without premature rupture of membranes in M. Jam- il Padang hospital, Achmad Muchtar Bukittinggi hospital, and Pariaman Hospital. There are significant differences in vitamin C blood plasma levels in term pregnancy with premature rupture of membranes and term pregnancy without premature rupture of membranes ( P < 0.05). Mean levels of vitamin C in blood plasma at term pregnancy with premature rupture of membranes lower than in the blood plasma levels of vitamin C in term pregnancy without premature rupture of membranes.Keywords: Premature rupture of membrane in aterm, blood plasma levels of vitamin C
