Bioavailability and pharmacokinetics of cefotaxime in Muscovy ducks
The pharmacokinetic profile of cefotaxime following a single intravenous (IV) and intramuscular (IM) injection was studied in Muscovy ducks. Cefotaxime was given at a dose rate of 25 mg/kg b.wt. for both routes. After IV injection, the plasma levels of cefotaxime estimated at 0.08 h was 70.87 μg/ml, which declined gradually and cefotaxime was detected up to 10 h (0.59 μg/ml). The mean values of...
متن کاملEffect of sex on muscular development of Muscovy ducks.
Muscovy ducks display marked sexual dimorphism. The aim of our study was to analyse the consequences of dimorphism on muscular growth and, particularly, on the myofibrillar typology of the Pectoralis major and Sartorius muscles. In the Pectoralis muscle, we only found two fibre types: red fast-twitch oxido-glycolytic fibres (about 90%) and white fast-twitch glycolytic fibres. In the Sartorius, ...
متن کاملMethane Generation from the Intestine of Muscovy Ducks, Mule Ducks and White
Livestock are one of the largest single sources of methane emissions, which is a greenhouse gas. In this study, alfalfa meal was tested as a feed additive to lower the methane generation in the three species of waterfowl. Four experiments were conducted to determine methane generation in the intestines of Muscovy ducks, mule ducks and White Roman geese of the same age and with the same diet. In...
متن کاملIsolation and characterization of a subtype C avian metapneumovirus circulating in Muscovy ducks in China
Subtype C avian metapneumovirus (aMPV-C), is an important pathogen that can cause egg-drop and acute respiratory diseases in poultry. To date, aMPV-C infection has not been documented in Muscovy ducks in China. Here, we isolated and characterized an aMPV-C, designated S-01, which has caused severe respiratory disease and noticeable egg drop in Muscovy duck flocks in south China since 2010. Elec...
متن کاملOccurrence of reovirus infection in Muscovy ducks (Cairina moschata) in south western Poland.
During the summer 2012 an incidence of high mortality, above 44 percent, in two flocks of Muscovy ducklings in Poland was noted. The clinical signs included considerable weight loss and inability to walk. During the post-mortem evaluations dehydration and enteritis, gouty kidneys as well as hemorrhagic liver and spleen lesions were found. The laboratory diagnosis included agar gel precipitation...
