  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 study on seroprevalence, seasonal occurrence and clinical manifestation of Newcastle Disease Virus (ND) among rural household chickens and Live Birds Markets (LBM) was conducted using haemagglutination Inhibition Test (HI) and questionnaires. A total of 1, 208 chickens reared under extensive management system in four Local Government Areas (LGAs) of Plateau State were used for the study. The seroprevalence of ND virus antibodies in rural chickens showed that there was no statistically significant (p > 0.05) difference among the four LGAs and of the 1,208 sera tested, 51.9% had detectable antibodies to NDV but only 14.1% of the chickens had HI antibody titre of > 4log2 which was considered as protective. About 86.2% of the chickens sampled were at risk of suffering from clinical ND. Newcastle disease outbreaks occurred year round in the villages sampled with the highest incidence of 86.6% observed from November to March (Dry season) and September to October, 8.31% (Pre-dry season). During outbreaks of ND, infected birds exhibit the following major clinical signs; nervous signs (32.4%), weakness (16.6%), whitish/greenish diarrhea (16.2%), coughing/sneezing 13.6%, anorexia 9.39% and others 11.8%. It was concluded that the prevalence of ND in the four LGAs of Plateau State is high. At the time of the study over 80% of rural chickens in Plateau State were at risk of dying from ND when exposed to a virulent NDV. It is therefore recommended that vaccination and improved management practices as a means of prevention against ND before the period of outbreaks should be instituted.

  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).

  Field outbreaks of coccidiosis all over the world were commonly reported in chickens over 3-weeks of age. Outbreak of coccidiosis in birds in the first few weeks of life is becoming increasing important but chickens less than 1-week of age appeared not to be susceptible. This case report describes the clinical signs and gross lesions of coccidiosis as well as its microscopic appearance in a five-day old intensively managed broiler breeder chicks. The outbreak occurred in December, 2009 and was characterized by early onset of an acute disease with high mortality. Other clinical features of the disease were: progressive increase and sudden decline of high chick mortality of up to 50%, ruffled feathers, blood stained whitish to brownish diarrhea, weakness and anorexia. Gross lesions seen were congested carcasses, distended caeca and intestinal segments with blood, mucus and tissue debris; retained yolk sac was also observed in some birds. Whole intestines were submitted to the Protozoology and retained yolk sac to Microbiology Laboratories for investigations. A farm visit revealed very poor housing ventilation and wet litter. Laboratory results confirmed coccidian schizonts and gametocytes from caeca and intestinal scrapings. Escherichia coli was isolated from the yolk sac. High hygienic standards must be maintained in hatcheries and poultry houses, damp and warm litter must be avoided and adequate ventilation should always be provided in poultry houses to prevent coccidiosis.

  Kogi state did not report Highly Pathogenic Avian Influenza (HPAI) during the 2006-2008 outbreaks in Nigeria despite the presence of favorable factors for the occurrence of the disease. A survey was conducted among stakeholders using structured questionnaires to determine the level of awareness, knowledge and readiness to report outbreak of HPAI and biosecurity practices in Kogi state, Nigeria. Awareness was 100% but knowledge of HPAI was low (9.1%). Readiness to report HPAI outbreak to relevant authorities was high (75.3%) but about 20% of respondents were not ready to report to any authority. Biosecurity practices evaluated by the presence of movement control was 38.8%; presence of footbath was rare (11.8%); handling of sick birds by isolation and treatment was 40%; improper disposal of dead birds in refuse dump was high (85.9%) and extensive management system was high (60.76%). The study revealed high level of awareness and readiness to report HPAI but poor knowledge and biosecurity practices towards it. The failures in biosecurity measures as seen in this study will greatly enhance introduction and spread of HPAI as well as other contagious poultry diseases in the state. Knowledge directly affects readiness to report hence efforts should be made to improve poultry stakeholders’ knowledge of HPAI and proper biosecurity practices.

  The rapid development of the poultry industry in Nigeria has resulted in an increase in the demand for poultry litter materials. Wood shaving is the most common and effective litter material used by the poultry industry in Nigeria though sawdust is also used to some extent by small poultry producers. The management of the deep litter in a poultry house is of the greatest importance and seems to be one of the most neglected aspects of poultry husbandry in Nigeria. It is frightening to see broilers, layers and breeders maintained throughout the winter months on accumulation of their own droppings. Parasitic and bacterial infection are highly likely and the most serious consequences of all are in breeder houses where wet litter can have a calamitous effect on the feet of the cocks causing accumulations of infected litter on the feet and subsequently leading to a fall in the level of fertility. Farmers here in Nigeria tend to pay little attention to litter management and concentrate on nutrition and disease control. The adoption of an appropriate strategy for litter management aiming at optimizing both bird performance and cost of production largely depends on the availability and good quality bedding material at affordable cost. The economic significance of good litter management practices are hereby highlighted in this study.
