GERZILOV, V. and P. PETROV. Relationship between some blood biochemical parameters and fatty liver weight in force feeding of mule ducks. Bulg. J. Agric. Sci., 21: 1039–1043 The purpose of this study was to determine the phenotype correlation between fatty liver weight (FLW) and some blood serum biochemical parameters in mule ducks – alanine aminotransferase (ALAT), aspartate aminotransferase (...

The purpose of the present survey was to review the important Non-pharmacologic treatments for fear of flying up to the present. This study is in the same way as some studies. Accordingly, some Non-pharmacologic treatments for fear of flying were assessed through this systematic review article. The general conclusion from the information provided by the  former studies, shows that a growing num...

Domestic ducks play an important role in the epidemiology of H5N1 highly pathogenic avian influenza (HPAI) viruses. Consequently, successful control of H5N1 HPAI in ducks is important for the eradication of the disease in poultry and in preventing infections in humans. Domestic ducks, however, include different species and breeds, and the susceptibility to infection, disease and response to vac...

The toxicity of maize containing known doses of fumonisin B1 (FB1) was investigated in mallard ducks during force-feeding. Seventy-five ducks at 12 wk of age were randomly divided into 3 groups of 25, and received control maize, naturally contaminated maize containing 20 mg/kg of FB1, or a mixture of control and contaminated maize (50/50, vol/vol). Force-feeding was performed during 12 d that c...

Immunofluorescence assays with fixed tissue sections were used to characterize antibody reactivity in sera obtained from duck hepatitis B virus-infected ducks. Under conditions of experimental infection, antibody to core antigen but not to surface antigen was detectable. A majority of the ducks infected at 8 days after hatching and a minority of those infected at 1 day after hatching showed a t...

A dose-response experiment with seven supplemental pyridoxine levels (0, 0.66, 1.32, 1.98, 2.64, 3.30, and 3.96 mg/kg) was conducted to investigate the effects of pyridoxine on growth performance and plasma aminotransferases and homocysteine of White Pekin ducks and to estimate pyridoxine requirement for these birds. A total of 336 one-day-old male White Pekin ducks were divided to 7 experiment...

Spending time in or around bodies of water ‘blue spaces’ can benefit human health and well-being. A growing body evidence suggests immersion blue space, e.g., participating ‘wild’ swimming, be particularly beneficial for both physical mental health. To date, wild swimming research has primarily focused on the experience individuals who swim sea. Empirical studies health-promoting potential fres...

Today, robots and unmanned aerial vehicles are being used extensively in modern societies. Due to a wide range of applications, it has attracted much attention among scientists over the past decades. This paper deals with the problem of the stability of a four-rotor flying robot called quadrotor, which is an under-actuated system, in the presence of operator or sensor failures. The dynamica...

This study was conducted to compare carcass characteristics and physico-chemical meat quality in two different genotype ducks raised under identical feeding and rearing conditions. A total of ninety 1-d-old Korean native ducks (KND, n = 45) and commercial meat-type ducks (Grimaud, n = 45) were fed same experimental diets during 56 d and 42 d, respectively to obtain similar slaughter weights. Th...
