the pharmacokinetics of cefpirome after a single intravenous injection of 10 mg.kg -1 was studied in febrile cross-bred calves. e. coli endotoxin was administered intravenously to induce fever in calves. blood samples were collected at different time intervals and cefpirome levels were estimated by using microbiological assay technique. based on the plasma drug levels, the pharmacokinetic param...
the present study was conducted on five healthy male cross bred calves to study the kinetic dispositionand urinary excretion of levofloxacin following its single subcutaneous administration at the dose of4 mg.kg-1. the concentration of levofloxacin in plasma and urine samples was estimated by microbiologicalassay. peak plasma level of levofloxacin (2.8 ± 0.3 μg.ml-1) was observed at 45 min and ...
BACKGROUND This study aimed to identify risk factors for active porcine reproductive and respiratory syndrome virus (PRRSV) infection at farm level and to assess the probability of an infected farm being detected through passive disease surveillance in England. Data were obtained from a cross-sectional study on 147 farrow-to-finish farms conducted from April 2008-April 2009. The risk factors fo...
The continued spread of highly pathogenic avian influenza (HPAI) viruses of H5 and H7 subtypes and low pathogenic avian influenza (LPAI) viruses of H5, H7 and H9 subtypes in birds and the subsequent infections in humans pose an ongoing pandemic threat. It has been proposed that poultry workers are at higher risk of exposure to HPAI or LPAI viruses and subsequently infection due to their repeate...
quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. this study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in gorgan city. cross-section survey data were gathered...

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...
