The main aim of the current investigation was to evaluate the relationships between metabolic parameters, acute-phase proteins, and the outcome of treatment of Staphylococcus aureus subclinical mastitis in dairy cows. Serum metabolic parameters and milk haptoglobin were measured in two groups: S....

The aim of present study was to evaluate the precision of plasma haptoglobin (HPT), serum iron (Fe) and plasma transferrin (Tf) concentrations as biomarkers of the severity of acute mastitis (AM) in cows. Fourteen Holstein Friesian cows with AM were divided into severe (n=8) and mild groups (n=6)...

The aim of this study was to evaluate the effects of dietary vitamin C supplementation on blood parameters of pre-parturient (PP) dairy cows and growth performance and immune system of their newborn calves. Forty PP cows (at approximately 21 days before calving and an average weight 791 ± 50 kg)...

Antioxidant components of colostrum prevent oxidative cell damage caused by free radicals that could harm the calf's development. The relationship of antioxidant potential of colostrum with parity is not well defined and could enlighten the importance of these components for the neonate and for the ...

Autonomic nervous function evaluated by heart rate variability (HRV) and blood characteristics were compared between Holstein Friesian cows that developed postpartum fever (PF; n = 5) and clinically healthy (CH; n = 6) puerperal cows in this case-control study. A cow was defined as having PF when...

Iron metabolism was examined in 15 bovine leukemia virus (BLV)-infected dairy cows (2.6-7.8 years old). BLV infection was detected by measuring serum antibody titer against BLV virus antigen (gp51). The anti-BLV antibody titers of the BLV-infected cows were significantly higher in serum than in...

Ceruloplasmin (Cp) plays an important role in copper transport and iron metabolism, as well as Cp is also an indicator for the health status of dairy cows. The present study reports the validation of an automated assay to assess the plasma Cp in dairy cows. Plasma Cp levels were determined in 40...

The late pregnancy (3^rd trimester) and the postpartum period (PPP) (calving date or day zero to day 45) are very critical periods for the fertility and production in dairy cows. This study was designed to investigate blood glucose, total protein (TP), calcium (Ca), phosphorus (P), magnesium (Mg), ...

Objective: The experiment was designed to establish suitable management strategies through the different feeding and breeding approaches on fertility improvement in the experimental repeat breeding (RB) cows. Materials and Methods: 80 RB cows were selected for this experiment. Before grouping, all ...

A total of 166 cross bred cows during their advanced gestation period were evaluated to study the deficiency of various macro and micro minerals. Blood sample was collected from all of them for evaluating the haemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), calcium (Ca),...
