Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...

The effect of host age on the outcome of duck tembusu virus (DTMUV) infection was studied in ducks. Three groups of Cherry Valley ducks at 1, 3, and 7 weeks of age were intramuscularly infected with DTMUV to systematically observe the clinical symptoms, pathological changes, tissue viral loads, and immune responses. Severe clinical symptoms and neurological dysfunction were observed in 1-week-o...

In order to evaluate geographical differences in the liver pathology of ducks infected with duck hepatitis B virus (DHBV), ducks in Chiba and Shimane, Japan, and Shanghai, China, were investigated. The numbers (DHBV positive/negative) and the maximum age of the ducks examined were 18/10 at 19 mo, 15/1 at 3 yr 4 mo, and 72/27 at 18 mo, respectively. DHBV infection was induced experimentally in d...

The pathogenicity of H5N1 highly pathogenic avian influenza (HPAI) viruses in domestic ducks varies between different viruses and is affected by the age of the ducks, with younger ducks presenting a more severe disease. In order to better understand the pathobiology of H5N1 HPAI in ducks including the role of host responses, 2 and 5-week-old Pekin ducks were infected with three different H5N1 H...

The pharmacokinetics aspects of levofloxacin were studied in healthy and experimentally renal damaged Muscovy ducks after single intravenous (IV) and oral (PO) dose of 10 mg kg(-1) bwt. Following IV administration, elimination half-life (t 1/2( β )) and mean residence time (MRT) were longer in renal damaged ducks than in healthy ones. Total clearance (Cltot) in renal damaged ducks (0.20 L kg(-1...

We conducted a study to evaluate the effects of intramuscular fat levels on the sensory characteristics of duck breast meat. Combining duck genotypes (Muscovy, Pekin, and their crossbreed hinny and mule ducks) and feeding levels (overfeeding between 12 and 14 wk of age vs. ad libitum feeding) enabled us to obtain a wide range of lipid levels in breast muscle. The average values were between 2.5...

West Sumatra has several breeds of germplasm ducks that have good potential for breeding, including Bayang Ducks, Kamang ducks, Pitalah and Sikumbang Janti ducks. This type duck develops in the origin area to produce eggs meat. The diversity performance these is still high. study aims determine various female during starter period. One hundred twenty heads local were used this study. an experim...

An experiment was conducted to study the effects of an emulsifier (glycerol polyethylene glycol ricinoleate: GPGR) and different sources of fat on the performance of Khaki Campbell ducks. Ducks were assigned into five groups with three replicates (10 ducks/replicate) in each group. Treatments were a control diet (C1: without added oil and emulsifier), control diet added with 2% soybean oil (C2)...
