A Mini-Review on Immunosuppressive Viral Diseases and their Containment Methods at Commercial Poultry Farms
Abstract views: 101 / PDF downloads: 16
Poultry diseases are one of the major issues of poultry farmers which cause severe economic loss in farming sector all over the world. Many of these diseases are due to viruses which can cause immunosuppression in birds. Also, these agents make birds susceptible to secondary bacterial infection and diseases. Some of these viral agents like Marekâ€™s Disease Virus (MDV), Chicken infectious anemia virus (CIAV), Infectious Bursal Disease Virus (IBDV), Reticuloendotheliosis Virus, Lymphoid Leukosis (LL) are silent killers which can cause detrimental and sometimes negative effects on the profitability of poultry farming. All possible attempts should be made to avoid sudden fluctuations in micro-climate of the poultry shed during seasonal changes using improved ventilation strategies, anti-stress nutritional supplementation, optimum stocking densities and strict biosecurity measures. These measures can help in preventing immunosuppression, and maintaining health and welfare of birds.
