    Opis:
    A total of 60 dairy cows met the requirements of the study (50 disease cases and 10 as the control group), located on 10 farms in the central Lublin region. The cows were aged 3 to 8 years, with good or very good milk production and about a week after parturition. They were first divided into two groups based on their clinical symptoms of milk fever. During the experiment, two subgroups were distinguished from the groups, based on the condition of the animals during the observation period. At 24, 48 and 72 hour,s blood was taken from the animals after no clinical symptoms were detected and at least 36 hours after the last administration of medicines. In the first days of the analysis, low levels of minerals (calcium – Ca and inorganic phosphorus – Pi) and low concentrations of glucose and cholesterol with simultaneously higher amounts of free fatty acids (FFA) were observed in the serum. On the second day of the analysis, these levels had dropped and on the third day some of the cows were observed to have small problems with appetite or difficulty getting up; therefore, after taking material for evaluation and analysis, treatment was begun or prophylaxis increased. Based on the results, the authors can conclude that the major health threat to cows recovering from milk fever appears 2 to 3 day after the subsidence of any signs of acute hypocalcaemia, and 3 days after the last application of medicines. Cows which had been clinically healthy in this period showed significant differences in biochemistry results versus the control groups and needed to receive prophylactic preparations to resolve the mineral and energy insufficiencies. Our observations suggest the necessity for check-up blood tests in cows for 3 days after an episode of milk fever, as well as mineral and energy prophylactic supplementation during that time.

    Opis:
    Copper deficiency is a common homeostatic disorder in dairy cattle farms in Poland. A simultaneous decrease in blood copper and iron concentrations is very rarely diagnosed and described in dairy cows. Copper is necessary for the mobilization of iron from the liver and its transport to bone marrow, where it is used for erythropoiesis. The aim of the study was to observe changes in haematological parameters in cows, resulting from copper deficiency or simultaneous deficiency of copper and iron, in comparison with animals from the same herds in which no deficiencies of these micronutrients were found. The study was conducted on 56 cows of the HF breed, aged from 3 to 6 years, from 3 dairy farms. The animals selected for the study were divided into three groups, two deficiency groups and one control group – without deficiency. Group I comprised animals with reduced concentration of copper in the serum, while group II comprised animals with low copper and iron concentrations. Group III comprised healthy cows without clinical symptoms and mineral deficiency. In both deficiency groups, the one characterized by a low concentration of copper, as well as the one with low concentrations of copper and iron, a reduction in red blood cell parameters, which was statistically significant versus the control group, was observed. In the examined animals, normocytic normochromic anaemia was found in group I, while normocytic hypochromic anaemia was diagnosed in group II. Cows with simultaneous Cu and Fe deficiency have worse milk yield results and they are more often culled from the herd. It is not clear why only some animals in a herd develop simultaneous deficiency of these micronutrients.

    Opis:
    Mycotoxin contaminations pose a growing problem in animal production from the economic and toxicological point of view. Clinical symptoms of mycotoxicosis are relatively unspecific, making the disease difficult to diagnose. This study presents a clinical case of dairy cattle infected with natural mycotoxins produced by fungi of the genus Fusarium (zearalenone [ZEA] and deoxynivalenol [DON]) in eastern Poland. In dead and infected cows, the presence of ZEA and DON was determined in the blood serum, significant changes were observed in blood morphological and biochemical profiles, extravasations and bowel inflammations were also observed. The results reported testify to an acute autoimmune process in the intestines as well as immunosuppression.

    Opis:
    The current methods of preventing calcium deficiency during the periparturient period are based primarily on a diet low in calcium and acidifying the rumen content before parturition, as well as on oral administration of liquid preparations or boluses. The available literature does not provide information on whether these forms of prevention are effective only immediately after the parturition, or whether they also affect an organism throughout the initial lactation period. The aim of the study was to examine the effects of three methods for the prevention of postpartum hypocalcaemia on selected indicators of mineral and energy metabolism, as well as on functional parameters of the parenchymal organs during the two week period following parturition in dairy cows diagnosed with low calcium concentrations before parturition, induced by a lower dietary mineral content. The study was conducted in 60 HF cows, aged 3-6 years old, fed TMR. The animals were divided into three groups: the first group received only a mineral preparation contained in the feed, adjusted to the physiological stage and milk production level; the second group received three additional doses (directly before the parturition, then 24 hours and 48 hours after the delivery) of an oral fluid preparation containing 62.5 g of Ca; while the third group received an intraruminal bolus containing 43 g of pure calcium (immediately after parturition). This research showed that physiological hypocalcaemia occurred at the beginning of lactation in the groups which had received additional calcium preparations (groups II and III), whereas in group I blood collection one week and two weeks after the parturition demonstrated subclinical hypocalcaemia. A statistically significant increase in magnesium and a decrease in phosphorus concentrations were also observed in the latter group, as well as an excessive GGTP activity and high bilirubin concentrations. Using only one complex mineral supplement in high yielding milk cows after parturition does not ensure the expected prophylactic effects, especially in the long term.

    Opis:
    Habanero pepper fruits contain capsaicin (CAP) characterised by a spicy taste. Astrocytes express vanilloid receptor (TRPV1), which interacts with cannabinoids including CAP. Only a few studies revealed that CAP leads to alterations of the arcuate nucleus (ARC) structures. The aim of this study was to analyse the GFAP (GFAP-IR) and S100β (S100β-IR) immunoreactive astrocytes of ARC in adult rats after intragastric administration of habanero pepper fruits. Adult, Wistar rats received a peanut oil – control group (C) – and oil suspension of habanero pepper fruits at a dose of 0.08 g dm/kg b.w. for 7 days – E1 group – and 28 days – E2 group. After euthanasia, the brains were embedded in paraffin blocks using a routine histological technique. Frontal slices of ARC were immunohistochemically stained for GFAP and S100β using specific antibodies in the peroxidase-antiperoxidase method. Astrocytes of ARC were morphologically and morphometrically analysed under a light microscope. The results of the study did not reveal statistically significant changes in the density of GFAP-IR cells in E1 and E2 groups of rats in comparison with group C. A statistically significant increase in the density of S100β-IR astrocytes was observed in the E1 group and a decrease in the E2 group. Astrocytes with expression of both studied proteins were characterised by morphological alterations in ARC in the E2 group. The obtained results suggest an influence of CAP contained in habanero pepper fruits on the reactivity of astroglia, which may have an impact on the astrocyte-neuron interactions in order to maintain a proper activity of nervous cells in ARC.

    Opis:
    Copper deficiency is a mineral management disorder increasingly often diagnosed in dairy cattle herds in Poland. Diagnosis of this disorder in herds can be very difficult as subclinical deficiencies may occur over long periods of time without clear clinical symptoms. Subclinical or atypical deficiencies that long remain untreated cause major disturbances in homeostasis. Information is scarce in the literature about the changes that occur in biochemical blood parameters in the course of atypical long-term subclinical copper deficiency. This study was conducted on a group of 80 cows from farms in the central part of the Lublin region in Poland. The animals were divided into four groups: three groups with Cu deficiency (two of these groups did not receive preventive supplementation, and the third one had oral copper supplementation administered) and a control group (clinically healthy cows). Blood for the tests was collected in the same period, 6 and 12 weeks after calving and a year after the previous tests. The results obtained in the groups where no special preventive measures had been taken showed a negative influence of copper deficiency on the functional condition of organs, especially the liver and pancreas (in the final stage of the study), and on blood phosphorus concentration. Such findings were not observed in the group supplemented with a copper-rich feed additive. In this group, after only a month of being supplemented with a preparation containing copper, a 15% increase in milk yield was observed. Meanwhile, the milk yield decreased in the remaining groups.
