The goal of the present study was to describe the clinical, haematological and ultrasonographic findings and treatment of 17 cattle with pyelonephritis. Fifteen cattle had an abnormal general condition, which varied in severity; five animals had signs of colic. The urine was brownish-red in 11 animals and cloudy in 13. Clumps of purulent material were seen in the urine of nine animals and clots...

Planned implementation of a nitrogen (N) “cap” on land in the Lake Taupo catchment has led to the need for a range of N mitigation options for pastoral farmers to increase profitability while farming within the N cap. A multi-disciplinary research programme has focused on the potential of targeting different parts of the N cycle to increase N efficiency and reduce N leaching losses. A range of ...

Losses in livestock production due to ectoparasite infestations exceed $2.26 billion annually. Over 50 species of ectoparasites infest cattle throughout the United States. The horn fly, Haematobia irritans (L.), is the most important and widespread of the five to six major pest species of pastured cattle in the southern region. Results from the examination of production traits from cattle under...

Determining a grazing animal's susceptibility to ergot alkaloids has been a research topic for decades. Our objective was to determine if the Promega™ P450-Glo assay could be used to indirectly detect ergot alkaloids or their metabolites in urine of steers. The first experiment validated the effects of ergot alkaloids [0, 20, and 40 μM of ergotamine (ET), dihydroergotamine (DHET), and ergonovin...

Reliable estimates of N excretion in the urine and feces of beef cattle are essential for developing cost-effective and environmentally sound nutrient management plans. A meta-analysis dataset was compiled that included data for starting live BW, DMI, N intake, dietary CP and RDP concentrations, urine N excretion, and feces N excretion. The data were taken from 12 individual feeding trials that...

Improvements to the efficiency of dietary nitrogen use by lactating dairy cattle can be made by altering the concentration and form of protein in the diet. This study collected urine and feces from dairy cows from selected crude protein (CP) treatments of 2 lactation studies. In the first trial, collections were made from cattle fed a diet with high (19.4%) or low (13.6%) CP content (HCP and LC...

BACKGROUND: Leptospirosis is a worldwide zoonosis causedby Leptospira interrogans. Leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. OBJECTIVES:The aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...

BACKGROUND There is a little or no data available on the natural Babesia bovis (B. bovis) infection in water buffaloes (Bubalus bubalis) comparing to the available one for cattle. This study was conducted to investigate the natural B. bovis infection in water buffaloes in comparison to crossbred cattle under field conditions in Egypt. METHODS A total of 35 buffaloes and cattle were clinically...
