The objective of the study was to assess ratio of oxidation to antioxidation in the blood of horses in selected equine diseases. The study was conducted on 47 Polish half-breed horses (36 mares, six stallions, and five geldings) aged 2 to 16 years. Nineteen mares were diagnosed with endometritis, seven horses with symptoms of colic, and six with upper respiratory tract infection. The remaining clinically...
The aim of the study was to evaluate the influence of immunomodulators (Propionobacterium granulosum + LPS vs lysozyme dimer) administered together with chosen antioxidants (vitamin C, β-carotene) on cellular immune response of high yielding cows in periparturient period. The study was conducted in a commercial dairy farm. Two weeks before the expected parturition and on the day of calving, 20 cows...
The objeclive of this study was to determine whether changes of biochemical indicators and T lymphocyte subpopulations during the prepartum period would differ between primiparous dairy cows that developed clinical metritis after calving and those that remained healthy. Cows that developed clinical metritis (53.3%) showed significant differences in age of the first calving and yield of milk during...
The aim of the study was to evaluate the incidence of the abnormal blood values of nonestrified fatty acids (NEFA), glucose, and aspartate aminotransferase (AspAT) in cows after parturition, as well as a retrospective analysis of the culling and fertility in groups of cows characterised by increased values of NEFA and/or AspAT. The study involved 164 dairy cows (primiparas and multiparas) with a milk...
The investigations were carried out on 35 dairy cows: 18 experimental cows receiving Inmodulen and 17 controls. Inmodulen, a bacterial immunostimulator was administered to experimental cows on the day of calving and on day 14 thereafter. The blood was sampled once a week during the first five weeks of lactation. The level of chemiluminescence (CL) was determined by a luminometer BioOrbit 1251. The...
The investigation was performed on 90 multiparous cows in four farms. Animals were almost identically fed and had similar milk yield during last year (6000 kg milk). Blood samples were taken 3 times (-3, -2, -1 week) before and 2 times (+1, +3 week) after parturition. Some biochemical parameters were determined. In all farms the increase of free fatty acids level was observed after parturition. The...
The investigations were carried out on 75 infertile cows with cystic ovarian disease, and 25 control cows with corpus luteum. The blood concentrations of ketone bodies, free fatty acids, glucose, total cholesterol and progesterone were determined before cyst treatment with GnRH. Levels of ketone bodies and free fatty acids were higher and progesterone level was lower in cystic cows than in control...
