This service is more advanced with JavaScript available, learn more at http: December7: Sincecases of haemorrhagic diathesis in young calves have been observed with a much higher incidence than previously known. The syndrome, now uniformly called Bovine Neonatal Pancytopenia BNPis characterized by multiple external and internal haemorrhages, thrombocytopenia, leukocytopenia, and bone marrow depletion. Although various infectious and toxicological causes of bleeding disorders in calves have been ruled out, the aetiology of BNP remains unknown.

However, field observations have led to the hypothesis that the aetiological Klee von Thrombophlebitis may be transmitted to calves via colostrum.

The objective of the present study was to verify whether ingestion of colostrum from dams of known BNP calves can elicit signs of BNP and typical haematological findings in conveniently selected neonatal calves. Six such calves received one feeding of colostrum or a mixture of colostrum batches from dams of Klee von Thrombophlebitis BNP calves. As controls, another six conveniently selected calves from herds which had never had a BNP case received one feeding of colostrum from their own dams.

Haematological and clinical parameters were Thrombophlebitis cesarean. One of the six experimental calves never showed any haematological, clinical or pathological evidence of BNP.

In the other five calves, thrombocyte and leukocyte counts dropped within a few hours following ingestion of colostrum. Of those, three calves developed clinical signs of BNP, their post-mortem examination revealed bone marrow depletion. Of the remaining two calves, a pair of mixed twins, marked thrombocytopenia and recurrent leukocytopenia was evident in one, in which only slight changes in the bone marrow were detected, Klee von Thrombophlebitis, while in the other thrombocyte counts dropped, Klee von Thrombophlebitis, but rebounded later, and no bone marrow changes were noted.

Thrombocyte counts of the experimental calves were statistically significantly lower than those of the control calves at 2 hours post ingestion of colostrum and at every sampling point between 9 hours and 8 days postcolostral. Leucocyte counts of the experimental calves were statistically significantly lower than those of control calves at 2 hours post ingestion of colostrum and days postcolostral.

BNP can be induced in some calves by ingestion of colostrum from cows that have given birth to BNP calves. During the 20 years precedingsporadic cases of unexplained bleeding in cattle of various ages, including, Klee von Thrombophlebitis, in andtwo calves less than four weeks of age with panmyelophthisis, were admitted to our clinic.

Starting inthere has been a remarkable surge in cases of bleeding disorder in young calves. In December,the scientific name "Bovine Neonatal Pancytopenia" BNP was adopted for this syndrome because of the characteristic changes in haematological parameters, Klee von Thrombophlebitis.

Other names are "haemorrhagic diathesis", "bleeding calf syndrome" or "blood sweating". The disease is defined by multiple external and internal haemorrhages, thrombocytopenia, leukocytopenia, and bone marrow depletion in calves younger than four weeks [ Klee von ThrombophlebitisKlee von Thrombophlebitis, 23456789 ]. No consensus exists with regard to presence of BVDV as an exclusion criterion. While the increase in incidence was first noted in Bavaria, cases have also been recorded in other federal states of Germany, albeit with striking differences in incidence.

Other European countries e. Various known causes of bleeding disorders e. Denmark, Klee von Thrombophlebitis, Austria, and Switzerland. The age at first appearance of clinical signs mean 14 days and observations by farmers were compatible with an aetiological Klee von Thrombophlebitis of colostrum. Except for one unconfirmed report from Scotland Klee von Thrombophlebitis 15 ] we are not aware of any evidence of thrombocytopenia occurring before colostrum intake.

The objective of this study, therefore, was to investigate the effect of colostrum of cows that had given birth to at least one calf affected by BNP on neonatal calves from farms where the disease had never occurred. The trial was approved by the ethics committee of the government of Upper Bavaria, and was carried out in cooperation with the Bavarian Authority of Health and Food Safety.

The incidence of BNP among the cattle population an estimated 50 cases among 1 million calves per year Klee von Thrombophlebitis yield a probability of 0. Therefore the null hypothesis was that the disease could not be reproduced by the feeding of colostrum, but that the disease occurs with a sporadic incidence of 0.

At the time of the sample size determination, owners of farms with BNP reported that more than half of the cows that had given birth to a calf later affected by BNP had another affected calf in the subsequent year. Two additional animals were enrolled as reserves in case of unexpected losses.

Since no Klee von Thrombophlebitis on thrombocyte counts in calves during their first few hours of life were found in the literature, six healthy calves Klee von Thrombophlebitis sampled as Klee von Thrombophlebitis. The dams of the experimental calves three Holstein Friesians and two Brown Swiss stood in one of two large dairy farms where BNP had never occurred. The dams of the control calves were six healthy cows five Holstein Friesians and one Simmental that had been purchased by the clinic for a different study from farms where Klee von Thrombophlebitis also had never occurred.

Tests were performed according to the manufacturers' recommendations. The dams of all experimental calves Klee von Thrombophlebitis all control calves, except for calf 8, had detectable BVDV antibodies. BVDV antigen was not detected in any of the samples. Information on experimental and Krampfadern Behandlung von Hopfen calves and the batches of colostrum fed.

All colostrum batches used were from Cows from which the colostrum was used: A and B had calves with BNP in and.

Six calves born within a 30 hour interval July were purchased from two large dairy farms I and II where BNP has never occurred previously and has not occurred since.

Calves 5 and 6 were mixed twins born by an HF cow. All calves were transported together to a barn close to the clinic one day after birth calves 1 and 2 or on Klee von Thrombophlebitis day of birth calves 3 - 6. There, the calves were housed in individual boxes with slatted wooden floors and straw bedding.

The barn had not been used for housing cattle for several years. The calves were kept in the same way as the experimental calves, but in the clinic. All calvings occurred under supervision so that the calves could not drink colostrum directly from their dams. Colostrum was provided to all calves in nipple buckets.

The experimental calves were fed one meal of colostrum from cows that had had at least one affected BNP calf in the past. Since not all colostrum samples exceeded three litres, some calves received a mixture of colostrum batches from two different cows.

The matching of experimental calves and colostrum batches is listed in Table 1. The first colostrum intake was between 1. The twins were fed their first meal at the barn close to the clinic.

Calves 1 - 4 received three litres of colostrum, and the twins calves 5 and 6 received two litres of colostrum. The control calves received three litres colostrum each from their own dams, which was milked at the clinic and offered to the calves within Krampfadern-Behandlung in Charkow to 3 hours after birth Table 1, Klee von Thrombophlebitis.

The milk originated from healthy cows milked at the clinic and at a neighbouring farm and was pasteurised at the clinic before feeding, Klee von Thrombophlebitis. An exception was the second and third meal for calves 1 and 2 of Klee von Thrombophlebitis experimental group that received whole tank milk from their farm of origin.

Fresh water, hay, and calf starter were offered free choice daily. An intravenous cannula was placed in a jugular vein of the experimental calves, and precolostral blood samples were taken. The cannula was left in place as long as possible, which varied between 3 and 14 days. If it had to be removed, Klee von Thrombophlebitis, calves were sampled by venipuncture.

While the cannula was left in place, the cannula was flushed prior and post blood sampling with sodium-citrate solution, and the first 10 ml of blood sampled were discarded. If no cannula was left, an gauge 1. The intervals between sampling and testing varied between 15 minutes and 24 hours due to the fact that some samples were taken on the farm of origin. The control calves were bled by venipuncture at exactly the same time points as the experimental calves.

The intervals between sampling and testing also varied between 10 minutes and 20 hours due to the fact that some control calves were born during the weekend.

Times of blood sampling and analyses performed in the experimental and control calves. After day 14 every 2 nd to 3 rd day until euthanasia or day Determination of cell numbers was performed using the semi-automated haematology analyser Sysmex F The study was approved by the ethics committee of the government of Upper Bavaria ref-nr.

The calves were planned to be observed for four weeks, Klee von Thrombophlebitis. Each day the calves were examined clinically with special attention being paid to the skin, oral mucosa, and faeces.

Body temperature was measured daily, Klee von Thrombophlebitis. Euthanasia was carried out when obvious BNP or other severe diseases e. It was necessary to allow development of the full range of clinical signs, including haemorrhages, Klee von Thrombophlebitis, in order to demonstrate the role of colostrum in this disease and allow for refinement in future studies.

All calves were sent for post-mortem examination immediately after euthanasia to the Bavarian Authority of Klee von Thrombophlebitis and Food Safety Oberschleissheim. Bone marrow of the femur and sternum was used for histological examination.

The control calves were not euthanized due to ethical and economical considerations, Klee von Thrombophlebitis, but were sold after being observed for four weeks, Klee von Thrombophlebitis. Due to the fact that statistical analysis was performed with six animals only per group, non-parametric tests were chosen.

For comparison of blood values between the two groups Mann-Whitney-U tests were employed, Klee von Thrombophlebitis. For graphical display Klee von Thrombophlebitis medians and quartiles were used.

In five of the six experimental calves the thrombocyte and leukocyte values dropped within the first three hours after intake of colostrum. Afterwards the courses varied.
