In dairy cattle in Switzerland, the prevalence of infection with Fasciola hepatica is over 16 per cent. Previous studies have suggested that even subclinical infections liver fluke may induce significant reductions performance cattle. The financial losses attributable to F were estimated using a simple spreadsheet model sum individual been literature. Because there substantial variability these production losses, Monte Carlo sampling techniques used this variability. Each cost item and each...
ABSTRACT Bovine anaplasmosis is a vector-borne disease that results in substantial economic losses other parts of the world but so far not northern Europe. In August 2002, fatal outbreak was reported large dairy herd Swiss canton Grisons. Diseased animals experienced fever, anorexia, agalactia, and depression. Anemia, ectoparasite infestation, and, occasionally, hemoglobinuria were observed. To determine roles pathogens to characterize disease, blood samples collected from all 286 animals:...
ABSTRACT A TaqMan PCR was established for identification and quantitation of members the Ehrlichia phagocytophila group in experimentally infected cows Ixodes ricinus ticks. The identified a 106-bp section 16S rRNA gene by use specific fluorogenic probe two primers. This technique E. group, which include , equi agent human granulocytic ehrlichiosis. system 10 copies cloned . sensitivity specificity were similar to those conventional nested PCR. numbers ehrlichiae leukocytes with measured...
An automated technique for recording eating and rumination behaviour was evaluated in ten lactating Brown Swiss cows by comparing data obtained from a pressure sensor with via direct observation over 24-hour period. The device involved integrated the noseband of halter. analysed variables included number duration individual rumination, resting phases, total daily length these phases cuds chewed per day. Eating were readily differentiated based on characteristic profiles. Chewing movements...
The reticulum and adjacent organs were examined ultrasonographically in 51 cows by use of a 3.5-MHz linear transducer applied to the ventral aspect thorax over sixth seventh intercostal spaces. Examination included assessment contour reticulum, reticular contractions, reticulum. normal appeared as half-moon-shaped structure with smooth contour; it contracted at regular intervals was situated immediately diaphragm portion abdominal wall when relaxed. Contents could not normally be imaged...
SUMMARY The size of the liver, as well situation and diameter vessels in cattle were determined by use ultrasonography. Ultrasonographic examinations liver performed on 10 cows times within 2 weeks, using a 3.5-MHz linear transducer right side 12th, 11th, 10th intercostal spaces. Dorsal ventral margin localization caudal vena cava portal vein each space. Furthermore, angle area between visceral surface diaphragmatic surface, dorsal margin, circumference gall bladder determined....
ABSTRACT Concomitantly with an outbreak of fatal anaplasmosis in a cattle herd Switzerland 2002, we detected two bovine hemoplasma species diseased animals: Mycoplasma wenyonii (formerly Eperythrozoon ) and second, novel later designated “ Candidatus haemobos” (synonym, haemobovis”). The second was characterized by shorter 16S rRNA gene. aims the present study were to provide detailed molecular characterization this species, develop specific quantitative real-time PCR assays for apply these...
The study investigated the ultrasonographic appearance of reticulum, rumen, omasum and abomasum calves with ruminal drinking syndrome. In ten milk-fed syndrome were examined by ultrasonography using a 5-MHz linear transducer before, during after ingestion milk. reticulum could be imaged in eight before feeding. reticular wall appeared as an echoic line, similar to mature cattle, folds seen calves. content heterogeneous fluid. Reticular contractions biphasic 1.0 ± 0.38 per minute. rumen had...
Polyphenols, like flavonoids, have been investigated when present in intact plants or extracts as methane mitigating dietary supplements ruminants. The aim of the study was to examine pure compounds a short-term vitro experiment using Hohenheim Gas Test method. We focused on group flavonoids and tested which them had potential mitigate without negatively affecting ruminal fermentation. Eight were tested: epicatechin, luteolin-7-glucoside, quercetin, isoquercetin Experiment 1; catechin,...
The study evaluated the results of clinical examination and haematological serum biochemical analyses in 503 cattle with traumatic reticuloperitonitis (TRP).The most common findings were abnormal demeanour general condition (87%), decreased rumen motility (72%), poorly digested faeces (57%), fill (49%), fever (43%) tachycardia (26%). In 58% cattle, at least one three tests for reticular foreign bodies (pinching withers, pressure on xiphoid percussion abdominal wall) was positive, 42% all...
Eating and rumination variables were recorded in 300 healthy lactating dairy cows of 3 different breeds (100 Brown Swiss, 100 Holstein-Friesian, Swiss Fleckvieh cows). monitored during a 24-h period using an automated system that jaw movements via pressure sensor integrated into the noseband halter. Phases eating reliably identified recordings based on typical patterns seen previous studies. The analysed included duration rumination, number chewing cycles regurgitated cuds per cud. ate for...
Objective The methane mitigating potential of various plant-based polyphenol sources is known, but effects combinations have rarely been tested. aim the present study was to determine whether binary and 3-way such phenol affect ruminal fermentation less, similar or more intensively than separate applications. Methods extracts used were from Acacia mearnsii bark (acacia), Vitis vinifera (grape) seed, Camellia sinensis leaves (green tea), Uncaria gambir (gambier), Vaccinium macrocarpon berries...
The clinical findings in 37 sheep and goats with acute ruminal lactic acidosis included a disturbed general condition characterised by anorexia, apathy, teeth grinding muscle twitching, stasis, the excretion of soupy or watery faeces. fluid affected animals was milky, had sour odour low pH. There predominance Gram-positive bacteria smears fluid. In comparison 10 control animals, rumen 23 higher acid lower volatile fatty concentrations. addition, often haemoconcentration metabolic acidosis....
