  The introduction of commercial poultry in Nigeria has rapidly revolutionarised the poultry industry over the years. This has increasingly raised concern in poultry waste disposal. About 932.5 metric tonnes of commercial poultry manure are annually produced in Nigeria. Ammonia gas is majorly a product of poultry manure and to some extent green house gases. Pathogenic microorganisms can thrive in poultry wastes. These constitute environmental and health hazards to livestock and the teeming population. The concern on how to manage poultry wastes under intensive production systems led to the discovery of suitable poultry droppings and moist absorbents referred to as litter materials. Caging birds may soon become unethical, wood shavings and saw dust are most popular but are increasingly used to manufacture other wood products, alternative litter materials are seasonally available, poultry litter is effectively utilized as nitrogen based fertilizer and livestock feed supplement, therefore, the demand and price for litter materials is magnified. Thus, farmers cannot secure enough good quality litter material for their birds. Economic losses due to poor litter are significantly high. In view of these therefore, careful selection, adequate management and proper storage and utilization of poultry litter are of paramount importance to reduce environmental pollution, disease spread and economic losses associated with poultry litter.

  A five year retrospective study (2004-2008) of the prevalence of Gumboro disease (infectious bursal disease, IBD) and other poultry disease diagnosed at the poultry unit of the Ahmadu Bello University Veterinary Teaching Hospital (ABUVTH), Zaria, Kaduna Nigeria was conducted. A prevalence of 7.26% (107 cases) was recorded out of 1473 cases of poultry disease. Gumboro disease occurred throughout the year in Zaria with a high incidence during the festival periods (July-September, October-December and January-March). The outbreaks of IBD were observed to be 1.3 times more likely to occur in pre-rainy season (April-June). Improved breeds of chickens were 5.8 times more likely to suffer from IBD than free range local chickens with broilers being 5.7 times more likely to suffer from the disease than other type of birds followed by layers kept together with cockerels. The prevalence of IBD is influenced by age of birds with an increase in the likelihood of IBD occurring within the age range of 3-5 week. Birds at 5 weeks old were at highest risk. Chickens with one vaccination history against IBD were 8.2 times more likely to suffer from the disease compared to non-vaccinated chickens. This study recommends that poultry farmers should be encourage to improve on farm biosecurity and ensure that their birds are vaccinated at least twice, before 3 and 5 weeks of age (at 1 and 3 or 2 and 4 weeks of age).
