Outbreak of Viscerotropic Velogenic form of Newcastle dis-ease in vaccinated six weeks old pullets
L Sa'idu, PA Abdu
Sokoto Journal of Veterinary Sciences , 2008,
Abstract: An outbreak of very virulent form of Newcastle disease in 6 week old pullets is reported. The flock was vac-cinated against Newcastle disease with Newcastle disease vaccine intra ocular at the hatchery and Newcastle disease vaccine Lasota at 4weeks of age at the farm. The signs noticed by the farm Manager were yellowish and greenish watery faeces, weakness and decrease in feed consumption. Response to treatment with Bioxin (oxy tetracycline) was poor. The sick birds never recovered. The gross lesions observed were: Necrosis of the gastrointestinal tract (Payers patches), caecal tonsils and bursa of fabricius. The disease lasted for 11 days and the mortality rate was 99.7%. The high mortality rate suggested that the vaccine had failed to immunize the birds against Newcastle disease and the birds were highly susceptible and had been infected with a very pathogenic stain of Newcastle disease virus.

L. Sa`idu,M. Bisalla,B. Moumini
Journal of Animal and Veterinary Advances , 2012,
Abstract: Three breeds of local chickens, Dwarf (DW), Frizzled Chicken (FZ) and Long Legged (LL) were purchased from the chicken market at Sabon Gari, Zaria and environs. Ten birds of each breed were bought making a total of 30 chickens. The birds were housed in the same pen to simulate local husbandry method. At three days after purchase the birds were bled to determine their Newcastle disease antibodies and then subsequently the birds were challenged with a local strain of Newcastle virus (Kudu 113). The birds were monitored for clinical signs and mortality. The mortality rates were: 60, 80 and 90% for DW, FZ and LL, respectively. The morbidity rate was 100% in all the breeds. The mean HI antibody titres before challenge were : 0.2, 1.4 and 2.0 for LL, DW and FZ, respectively. At 5 weeks post challenge the mean HI antibody titres were : 1024 for both DW and FZ and it was 32 for LL. The clinical signs seen in all the breeds were similar to those seen in the velogenic viscerotropic form of Newcastle Disease ( ND ). The post mortem lesions seen in all the breeds were similar to those seen in the velogenic viscerotropic form of ND. The study showed that all the breeds were equally susceptible to ND. Unlike the belief of the Hausas that the FZ is resistant to ND. It was concluded that there is no breed difference among the local chicken in susceptibility to ND and that there is the need for further studies on the claim that the local chicken is resistant to ND viral infection.
Knowledge of poultry diseases, biosecurity and husbandry practices among stakeholders in poultry production in Kogi State, Nigeria

Sokoto Journal of Veterinary Sciences , 2012,
Abstract: Commercial poultry production is low in Kogi State even before the advent of highly pathogenic avian influenza (HPAI H5N1) outbreak in Nigeria. The low level of poultry production has persisted long after the socio -economic impacts of HPAI had improved. A study was conducted among 94 poultry stakeholders in the state with the use of questionnaire to assess their knowledge of poultry diseases, biosecurity and poultry husbandry practices in six Local Government Areas of Kogi State. The findings showed that 60.0% of poultry production was rural while the rest were backyard (semi commercial) poultry. About 64.7% of poultry kept were under extensive management with the commonest diseases seen under this management system being Newcastle disease (62.9%), Coccidiosis (52.3%), Fowl pox (46.9%), Gumboro disease (39.1%) and Fowl typhoid (36.1%). Biosecurity was poor as 92.9% of respondents did not have footbath or hand wash disinfection; 70% would throw away poultry litter in the refuse dump; 12% would use the poultry litter as manure while 11% would sell out the litter. In addition, 64.7% of the poultry farmers obtained their rearing stock from the live bird market and other unknown sources while only 35.3% obtained theirs from the hatchery. The findings of this study showed that the low level of commercial poultry production in Kogi State might be due to the impacts of diseases and poor husbandry practices undertaken by the farmers. It is recommended that government should train poultry farmers on biosecurity, disease prevention and the adoption of modern husbandry practices suitable for the traditional poultry production system.
Retrospective studies on pullorum disease in chickens in Zaria, Nigeria
AM Wakawa, L Sa'idu, PA Abdu, PH Mamman
Sokoto Journal of Veterinary Sciences , 2008,
Abstract: A twelve-year study (January, 1995 - December, 2006) of case reports on Pullorum disease (PD) and other poultry diseases diagnosed at the Ahmadu Bello University Veterinary Teaching Hospital, Zaria, was conducted. A total of 3, 265 outbreaks were documented with 173 (5.3%) of the outbreaks diagnosed as PD. The annual increase in the number of PD outbreaks implied a decline in the hygienic standards of hatcheries where the first cycle of transmission should be broken. It was observed that chickens raised between June and August, layers and broilers, chicks under 4 weeks of age, and chickens raised under intensive system of management were at greatest risk of suffering from PD outbreaks. It is imperative that regular blood testing of parent stocks for S. Pullorum infections be conducted routinely to eliminate carriers. There is also the need for poultry farmers to institute and intensify biosecurity measures on their farms to minimize horizontal transmission of PD.

Review of highly pathogenic avian influenza outbreaks in poultry in Zaria, Nigeria
AM Wakawa, L Sa'idu, PA Abdu, TM Joannis
Sokoto Journal of Veterinary Sciences , 2008,
Abstract: All the confirmed highly pathogenic avian influenza cases that were diagnosed in Zaria at the Veterinary Teaching Hospital, Ahmadu Bello University, Zaria, Nigeria, were reviewed in this study. The outbreaks occurred between the months of December, 2006 and March, 2007. The clinical signs and postmortem lesions were similar to those observed in avian influenza outbreaks elsewhere. It was observed that the cold windy harmattan condition, the addition of new birds into an already existing flock, the low compensation rate paid to farmers; and poor biosecurity measures on the affected farms might have contributed to the spread of the disease in Zaria and environs.
Risk factors for the occurrence and spread of Highly Pathogenic Avian Influenza H5N1 in commercial poultry farms in Kano, Nigeria

Sokoto Journal of Veterinary Sciences , 2012,
Abstract: Outbreaks of Highly Pathogenic Avian Influenza (HPAI) subtype H5N1 occurred previously for three consecutive years, 2006, 2007 and 2008 in Kano State, Nigeria, causing heavy economic losses to farmers and the government. It was against this background that risk factors for the occurrence and spread of HPAI H5N1 among commercial poultry farms in the State were evaluated. A total of 64 farms comprising 32 affected (AF) and 32 non-affected (NAF) farms were enrolled for this study. Questionnaires were designed and administered to the selected farms through interviews with farm owners or farm managers during on-site visits. Information on flock profile including farm characteristics and environment, husbandry practices, biosecurity practices, farm trade practices and employee activities were obtained and analyzed. Pearson Chi square and Fisher’s exact tests were used to compare categorical variables. Values of p< 0.05 were considered significant. Odds ratios (OR) and 95% confidence intervals (CI) were calculated to measure the strength and statistical significance of associations between the variables and occurrence and spread of HPAI H5N1 in commercial poultry farms in the State. The most significant risk factors were the presence of untreated surface water on farms (OR 18.6, 95%CI 2.24 – 154.34, p = 0.001), exchange of egg crates between traders and farmers (OR 12.1, 95%CI 1.43 – 102.61, p = 0.006), allowing egg crates of traders into poultry pens (OR 11.67, 95%CI 2.37 – 57.86, p = 0.001) and allowing rodents/wild birds access to poultry feed (OR 3.65, 95%CI 0.23 – 1.87, p = 0.024). It was recommended that veterinary inspection to enforce and encourage best biosecurity practices for the poultry farms should be introduced and sustained.

Clinical Evaluation and Surgical Management of Some Important Reproductive Problems of Intensively Raised Chickens in Zaria, Nigeria  [PDF]
Waziri I. Musa, Saidu T. Muhammad
Open Journal of Animal Sciences (OJAS) , 2015, DOI: 10.4236/ojas.2015.53036
Abstract: Almost all healthy female chickens are expected to optimally produce eggs regularly. To maximize profits, nonproductive birds are often culled in commercial layer farms without due considerations to causes. Genetic and therapeutic manipulations to increase egg production per cycle often predispose birds to obstetric problems. Information on the detection and management techniques of reproductive abnormalities of the domestic chicken appear scarce. This study reports on clinical evaluation and surgical management of three major reproductive abnormalities of the commercial layer chickens. Egg yolk peritonitis, oviduct impaction and egg bound conditions were diagnosed and surgically managed following standard surgical procedures. Palpation and abdominocenthesis using flexible rubber catheter, abdomino-pelvic ultrasound scan and ventra-dorsal X-ray techniques were used to establish diagnosis. In all reported conditions herein, surgery was employed to correct them. The study showed values of diagnostic imaging and surgery to correcting obstetric conditions of domestic chickens.
Non-Associative Property of 123-Avoiding Class of Aunu Permutation Patterns  [PDF]
Aminu Alhaji Ibrahim, Saidu Isah Abubakar
Advances in Pure Mathematics (APM) , 2016, DOI: 10.4236/apm.2016.62006
Abstract: This paper presents the non-associative and non-commutative properties of the 123-avoiding patterns of Aunu permutation patterns. The generating function of the said patterns has been reported earlier by the author [1] [2]. The paper describes how these non-associative and non commutative properties can be established by using the Cayley table on which a binary operation is defined to act on the 123-avoiding and 132-avoiding patterns of Aunu permutations using a pairing scheme. Our results have generated larger matrices from permutations of points of the Aunu patterns of prime cardinality. It follows that the generated symbols can be used in further studies and analysis in cryptography and game theory thereby providing an interdisciplinary approach and applications of these important permutation patterns.
