Abstract:
The Newcastle disease virus (NDV) negative-strand RNA genome containssix genes. These genes encode nucleoprotein (NP), phosphoprotein (P),matrix protein (M), fusion protein (F), hemagglutinin-neuraminidase (HN),and RNA-dependent RNA polymerase (L) proteins. The six proteins affectthe virulence of NDV in different ways, but available information on thesix proteins is disparate and scattered across many databases and sources.A comprehensive...

Abstract:
Reports of avian malaria parasites in village chicken in Nigeria generally remain fragmentary and scarce. The study was conducted in Gombe Local Government Area of Gombe State, Nigeria to investigate avian malaria parasites in Village Chickens (Gallus gallus domesticus) and to determine the risk factors associated with the prevalence of the haemoparasites. A total of 530... More
ArticlesInvestigation of Two Precipitation Methods for Extracting Immunoglobulin Y (IgY) from Egg Yolks

Abstract:
Two groups of hens (control and immunization group) were arranged in an experimental design with an immunization schedule of 3 injections of BSA antigen. IgY antibodies were extracted from egg yolks by two precipitation processes (chloroform and polyethylene glycol precipitates) and quantified using a standard curve of protein concentration. The purification of IgY
was confirmed by... More

Abstract:
Studies have reported on the economic impacts of clinical and subclinical mastitis on dairy farms. Bovine mastitis is a disorder that affects dairy farms and has a major economic impact. Most of the economic losses are the result of mastitis. Mastitis is an invasive infection that is among the most numerous and highly complicated infections... More

Abstract:
The rapid weight gain and fast muscle growth due to intense genetic selection and improved nutrition for additional breast muscle in broiler commercial strains affect chickens health. In order to compare the main locomotive problems in broilers of Cobb and Ross strains, two pens from a commercial farm in Veracruz, Mexico were used. The first... More
