The aim of the study was to assess values and correlations between selected markers acid-base balance electrolytes in blood late lactation cows, such as pH, pCO2, pO2, HCO3 –, BE, BE(B), Na+, K+, Cl–, well parameters milk, number somatic cells (SCC), colony forming units (CFU), milk fat (MF), protein (MP), lactose (ML), solids, solids non-fat (SNF), current production. Blood samples were collec...

The aim of this study was to evaluate the effect of the season (ambient temperature and relative humidity) on some blood metabolites in dairy cows during postpartum period. Blood samples were collected from 195 clinically healthy dairy cows of 8 Italian dairy herds in spring (April-May 15.5±4 °C and 69.5±0.7 %), summer (June-July 23±1.5 °C and 69±1.3 %) and autumn (September-October 17±2 °C and...

To establish a method to predict postpartum diseases using prepartum back fat thickness (BFT), the peripartum BFTs of 54 healthy multiparous cows before calving, which were diagnosed with postpartum displacement of the abomasum (DA), clinical ketosis or subclinical ketosis were compared with those of healthy cows from 8 weeks before the expected calving date to 8 weeks after calving. The peripa...

This study was designed to determine a reference range of haptoglobin (Hp) in Iranian Holstein cattle of different ages and of both sexes, and to evaluate Hp as marker in some inflammatory diseases in Shiraz, a tropical area in southern Iran. Blood samples were collected from the coccygeal vein of 50 clinically healthy cattle and 36 cows with various inflammatory diseases (acute diffuse traumat...

INTRODUCTION AND OBJECTIVE The aim of study was to test the sera of healthy dairy cows by ELISAs, the methods also used in other groups of animals in the Czech Republic, and thus to obtain actual data about N. caninum and T. gondii seroprevalence in cattle. MATERIAL AND METHODS In the Czech Republic, sera from 546 clinically healthy dairy cows (Bos primigenius f. taurus) aged > 2 years from 4...

Background: There are accumulating evidences showing the role of adiponectin, a newly discovered adipocytokine secreted from adipose tissue, in the regulation of the ovarian function in dairy cows. The objective of the present study was to evaluate the pattern of serum adiponectin concentration during a normal estrous cycle in the postpartum dairy cows. Materials and Methods: Coccygeal vein blo...

An unexplained haemorrhagic disorder of young calves, Bovine Neonatal Pancytopaenia (BNP), has appeared in Europe since 2007. BNP affected 14 beef calves born between March 2009 and April 2010 in 210-cow Scottish beef herd; only one calf survived. During both calving seasons the cows appeared clinically well and calved normally, giving birth to apparently healthy calves of a good birth weight. ...

Mastitis is one of the most important diseases of dairy cattle in the world. The identification and characterization of the constituent proteins in milk can be useful for studying the biochemistry and pathogenesis of mastitis. In this study, the electrophoretic patterns of milk from 10 healthy and 30 mastitic cows were studied. All of the latter milk samples were California Mastitis Test (CMT) ...
