AIM Mycoplasma gallisepticum (MG) is important avian pathogens responsible for chronic respiratory diseases of chicken and turkeys, which result in large economic loss for the poultry industry. The objectives of this study were determination of seroprevalence of MG antibody of commercial layer chicken at laying period in selected areas of Bangladesh. MATERIALS AND METHODS A total of 563 blood...

The glial cell line-derived neurotrophic factor (GDNF) is a well-known growth factor acting on many neuronal populations of central, peripheral and autonomous nervous system. This factor was also previously detected in the retina of developing rat and chicken while no data are available for the zebrafish. In this study transcripts of GDNF mRNA were observed in adult retina extracts by RT-PCR. T...

Chronic Respiratory disease is an economically important disease of chicken caused by Mycoplasma gallisepticum. The present study was carried out to study the incidence and factors affecting the incidence of CRD in poultry flocks under Indian conditions. Incidence during different seasons, among different types and breeds of chicken and among different age groups were studied. The overall incid...

The alimentary tract is incessantly invaded by foreign antigenic or harmful substances and their lumina are also sites for the proliferation of both beneficial and disadvantageous bacterial flora (Mead, 1989 and Kitagawa et al., 2000). Caecal tonsil, the immunodefence mechanism of the caecal environment regulates the proliferation of microflora in the caecum continuously and also prevents the i...

A procedure was developed to determine nosiheptide residues in marketed meat and egg. Acetonitrile was used for the extraction, and the extract was partitioned with hexane to remove fat. The lower layer was reconstructed and quantitated by liquid chromatography using fluorescence detection at 357 nm excitation and 500 nm emission. The mobile phase consisted of 0.025% phosphoric acid-acetonitril...

Spray application of Mycoplasma gallisepticum (MG) vaccines is a labor- and time-saving means of mass vaccination of layer chickens. Recent assessment of spray characteristics of nozzles commonly used to apply MG vaccine in layer chicken operations has shown that the amount of respirable droplets (< 5 microm) is negligible. Topical application of vaccine onto the eye surface has been suggested ...

Salmonellosis is a disease of human beings, cattle, sheep, goat, pigs and chicken including duck and is manifested clinically in all hosts by one of three major syndromes: a peracute systemic infection, acute enteritis or chronic enteritis. But the clinical signs may vary from species to species1. Human infections with Salmonella have been increasing worldwide since 1980 and have been shown to ...

Hen’s native chicken reproductive organ health status evaluation is important for raising Indonesian native chicken in order to support protein supply for people demand. This study aimed to discover the images of Indonesian hen’s native chicken reproductive organ using ultrasonography. There were 18 hens that used in this study and divided into two groups, 15 hens for brightnessmode ultrasonogr...

The present study was conducted to evaluate the effect of chilled drinking water on the productivity of laying hens under constant high ambient temperature. A total of seventy-two, 123-day-old Hy-line brown layers was divided into two equal groups. The first group (UDWG) was given unchilled water (23.0±2.5°C) as a control, and the second group (CDWG) was given chilled water (16.0±0.5°C). The la...

Solution-processed inverted bulk heterojunction (BHJ) solar cells have gained much more attention during the last decade, because of their significantly better environmental stability compared to the normal architecture BHJ solar cells. Transparent metal oxides (MeOx) play an important role as the dominant class for solution-processed interface materials in this development, due to their excell...
