Clinical toxoplasmosis in chickens (Gallus domesticus) has been rarely reported in literature. Here we report that three chickens on a farm in Illinois developed neurological signs. One of these chickens was examined postmortem and it had non-suppurative encephalitis with numerous Toxoplasma gondii tachyzoites and tissue cysts. The identity of the protozoa was confirmed immunohistochemically by...

A galacto-oligosaccharide (GOS) prebiotic was prepared by reacting a high concentration of lactose (40% wt/vol) with a beta-galactosidase enzyme for 24 h at 37 degrees C. The enzyme was produced from recombinant Pichia pastoris X-33 cells. The study aimed at evaluating the effects of the prebiotic, a Bifidobacterium lactis-based probiotic, and the combination of these dietary additives on BW, f...

infected with cestodes through ingestion of their arthropod intermediate hosts. In the present study, Raillietina sp. was recovered in relatively small numbers compared to Nigerian indigenous chickens that were reported to harbour more tapeworms than ascarids. Similarly, indigenous chickens from southern Ethiopia were reportedly infected with various types of tapeworms. The presence of cestodes...

Thirteen oncogenic and necrotizing animal viruses were assayed in LIFE Sciences, Inc. (LSI)-specific pathogen-free Japanese quail and LSI-specific pathogen-free chicken embryo cell cultures. Nine viruses produced similar titers in the quail and chicken cell systems, whereas four viruses showed significantly higher titers in chickens. Young Japanese quail and chickens were inoculated with five s...

The study determined the effects of garlic, ginger and their mixtures on the growth, serum lipids, haematological indices, carcass and organs of broilers. Garlic and ginger were each added to broiler diets at 1, 1.5 and 2%. Four mixtures of garlic and ginger were also formulated. Control diet did not contain any test ingredient. The results showed that garlic, ginger and mixtures contained 7.41...

BACKGROUND Tibetan chickens living at high altitudes show specific adaptations to high-altitude conditions, but the epigenetic modifications associated with these adaptations have not been characterized. RESULTS We investigated the genome-wide DNA methylation patterns in Tibetan chicken blood by using whole genome bisulfite sequencing. Generally, Tibetan chickens exhibited analogous methylati...

Chicken and egg food traceability system based on NFC QR code technology was designed. The registers uploads the information of raised chickens through chicken foot ring embedded with tag. generates according to registered prints it eggs corresponding chickens. It is used for consumer users scan query relevant chickens, including breeding address, breeder record designed classic three-layer mod...

Marek's disease (MD) has been occurring with increasing frequency in chickens in recent years. To our knowledge, however, there has been no report of the very virulent plus (vv+) MD virus (MDV) field isolate in China. Studies have shown that dual infection with immunosuppressive viruses such as chicken infectious anemia virus (CIAV) occurs frequently in chickens developing MD. In this study, we...

Mycoplasma gallisepticum infection in chickens leads to tracheitis, airsacculitis, poor feed conversion and reduced egg production, resulting in considerable economic hardship on the poultry industry. The chemokines and cytokines responsible for recruitment, activation and proliferation of leukocytes in affected tissues have not been described. In the current study, chemokine and cytokine gene ...

Myosin heavy chain (MyHC), one of the major components in the contractile machinery of skeletal muscle fibers, is found in several isoforms during myogenesis. During chicken development, embryonic, neonatal, and adult MyHC isoforms are expressed. Broiler chickens have been selected for fast and large muscle growth, whereas Single Comb White Leghorn (SCWL) chickens have been selected for egg lay...
