Poultry meat is one of the most important sources protein for human consumption worldwide. Chicken and turkeys are considered as healthy because they have relatively low levels saturated fat compared with red meat. Kadaknath a native breed, found in tribal dominated Jhabua district Madhya Pradesh, India. But its priced three times more than that broiler chicken. Narmada Nidhi an improved locati...

An experiment was conducted to evaluate the feeding of four medicinal mushrooms via fungus myceliated grain (FMG) at three levels on production performance, blood parameters and natural coccidiosis oocyst excretion in floor reared broiler chickens. Three hundred day-old female broiler chickens were weighed and randomly assigned to nine different treatment groups. Each group was replicated three...

The vast majority of lymphocytes generated daily in the chicken bursa of Fabricius do not emigrate to the periphery but die in situ. Apoptotic cells in the bursa can be readily detected by the presence of fragmented DNA and by the large numbers of condensed cellular nuclei observed by electron microscopy. Consequently, most newly generated lymphocytes die by programmed cell death. We show that ...

The objective was to evaluate lymphoid organ size in chickens from a series of 13 recombinant congenic strains (RCS) and their highly inbred parental lines (6(3) and 7(2)). The parental line 6(3) was selected for resistance to tumors induced by Marek's disease virus and avian leukosis viruses, whereas line 7(2) was selected for susceptibility to these tumors. Each RCS on the average contains a ...

Infectious bursal disease (IBD) is characterized by immunosuppression due to the depletion of lymphocytes in the atrophied bursa of Fabricius (BF). We have sometimes encountered contradictory findings: chickens infected with the vaccine IBD virus (IBDV) strain have sometimes exhibited a highly atrophied BF, but not immunosuppression. In this study, chickens administered vaccine or wild-type str...

The distribution of the immune complex vaccine virus for infectious bursal disease (IBD) in tissue was examined and the viral loads of the organs were quantitatively compared. One-day-old specific pathogen free (SPF) and maternally immune broiler chickens were injected subcutaneously with the vaccine. Lymphoid and non-lymphoid tissues were collected at various time intervals during the experime...

In spite of the intensive and varied vaccination procedures to control Infectious Bursa Disease (IBD), the emergence of a very virulent (vv) IBD pathotype in Ghana has led to high economic losses in the poultry industry. The potencies of two live intermediate IBD vaccine strains (TAD and Nobilis D78) and an intermediate-plus (hot) vaccine strain (228E) used in Ghana were evaluated by challengin...

The aim of this work was to investigate developmental changes in cell proliferation and apoptosis in normal duck bursa of Fabricius using flow cytometry and immunohistochemistry. Studies were carried out on Tianfu ducks on days 24 and 27 of embryogenesis (E24 and E27) along with days 20, 70, and 200 of postnatal development (P20, P70, and P200). Results showed that the percentage of G0/G1 bursa...
