The influence of different copper and zinc contents in rations on blood serum concentrations dependence feeding (Groups A B) lactation (Lactation 1 2) was tested a trial with 60 German Holstein cows. All animals received diet based maize grass silage ad libitum. 30 cows concentrate supplemented as recommended (Group A), whereas the other were offered roughly double amount B). Blood samples taken several times during to analyse zinc. Copper concentration influenced neither by (11.7 mumol/L...
Isolated syndactyly in cattle, also known as mulefoot, is inherited an autosomal recessive trait with variable penetrance different cattle breeds. Recently, two independent mutations the bovine LRP4 gene have been reported primary cause of Holstein and Angus We confirmed previously described exon 33 nucleotide substitution most affected calves revealed additional evidence for allelic heterogeneity by identification four new non-synonymous point co-segregating Holstein, German Simmental...
Babesia divergens, transmitted by the tick Ixodes ricinus, is most common cause of bovine babesiosis in northern Europe and plays a role as zoonotic pathogen. However, several studies have indicated decline B. divergens prevalence during last decades. Here, we investigate epidemiology on beef production farm Germany, which had not been affected until an initial outbreak 2018. In June 2018, 21 adult cattle died, showing classical symptoms babesiosis. merozoites were detected blood smears...

The essential trace element selenium is indispensable for male fertility in mammals. Until now, little data existed regarding the relationship between and sperm quality stallion. Selenium, or selenium-dependent glutathione peroxidase activity, was determined red blood cells, semen, seminal plasma spermatozoa, percentages of spermatozoa with progressive motility (PMS), intact membranes (PMI), altered (positive) acrosomal status (PAS) detectable DNA damage, by chromatin structure assay, were...
Summary The aim of this study was to determine the influence fumaric acid ( FA ) on ruminal fermentation and its effects acid‐base balance seven ruminally duodenally fistulated multiparous German Holstein cows. experiment conducted in a change‐over design with three periods which animals were randomly arranged one treatments: Control (C; without FA), 300 or 600 g per day. diets consisted 7.4 kg DM grass silage, 4.2 concentrate mixture 0, wheat starch as isocaloric compensation day cow....
The hard tick Ixodes ricinus transmits a variety of zoonotic pathogens, including Babesia divergens, the most common cause bovine babesiosis in northern Europe. In endemic areas, cattle are rarely clinically affected, as animals up to age nine months resistant against relevant clinical disease and develop protective premunity. However, outbreaks immunologically naïve herds may lead considerable losses. Such an outbreak with high mortality rate occurred 2018 on German beef production farm,...
Summary The present investigation was undertaken to study the effects of surgical stress on thiobarbituric acid reactive substances (TBARS) and ferric reducing ability plasma (FRAP) in dairy cows. Ten Holstein–Friesian cows, mean age 5.26 years, admitted for treatment left abomasal displacement (omentopexy), were used our study. Blood samples collected from jugular vein prior surgery, immediately then 15, 30, 60, 90 min, 2, 5, 10, 24 h after reposition abomasum. Surgical resulted a...
Human patients suffering from exocrine pancreatic insufficiency (EPI) are susceptible to deficiencies in fat-soluble vitamins. In children with cystic fibrosis, EPI is common and aspects of sufficient vitamin supply special interest. The aim this study was determine the best application form maintain A E levels physiological range growing pigs (induced by duct ligation) as a model for children. ligated (PL) twelve 8-wk-old pigs; 4 sham-operated served controls (Con). Pigs (n = 16) were...
The aim of the present study was to determine effects potential methane reducer fumaric acid on fattening performance and acid-base balance growing bulls fed two different silage types as roughage (maize grass silage). A total 62 (German Holstein breed, initial body weight: 266 +/- 42 kg), randomly assigned eight feeding groups, received four levels (0, 100, 200 or 300 g/d) at each type. daily feed water intake live weight were measured over whole testing period 280 days. In blood samples,...
In the present study we aimed to compare arterial and venous plasma ammonia in dairy cows with fa�y liver hepatic failure.75 Holstein-Friesian were used investigation.Clinical examinations revealed failure 14 (group LF).Diagnosis of was based on clinical signs encephalopathy, including anorexia, depressed consciousness, ataxia, somnolence, coma, >35 µmol/l.The other divided according their triglyceride content (wet tissue) into following groups: low triglycerides (LT) < 30 mg/g (n = 24),...
Bovine babesiosis, caused by Babesia divergens, is in general a rare disease Europe. Nonetheless, local outbreaks can cause severe economic damage, and postmortem identification represents diagnostic challenge. During recent outbreak May 2018 northern Germany, 21 animals of herd 150 cattle died within 40 days having had clinical signs fever hemoglobinuria. Gross examination 4 the deceased revealed tick infestation, jaundice, dark brown staining urine kidneys. Histologically, there were...
Zusammenfassung Gegenstand und Ziel: Thiaminmangel verursacht bei Katzen häufig zentralnervöse Ausfallerscheinungen, ist verbunden mit einer Dysfunktion des Vestibularsystems kann unbehandelt zum Tod führen. Ziel der Arbeit war, Thiamin direkt mittels High Pressure Liquid Chromatography (HPLC) zu bestimmen Werte gesunden kranken evaluieren. Material Methoden: In Blutproben von 193 wurden HPLC die Konzentrationen an Thiamindiphosphat Gesamtthiamin bestimmt. Zur Auswertung Daten erfolgte eine...
