ABSTRACT
Parasitism is of great concern to the wellbeing, productivity and reproductivity of animals and it causes great financial loss to the economy of any nation. This study was conducted to determine the prevalence and the economic loss from carcass and viscera condemnation due to parasitic diseases in slaughtered cattle in Kwara State, North-central Nigeria. A 16 year (2003-2018) record of parasitic diseases detected in cattle slaughtered at the major abattoirs in Ilorin city was retrieved from the Kwara State Veterinary department of the Ministry of Agriculture and Natural Resources. The total prevalence as well as the yearly, monthly and seasonal prevalence of each of the documented parasitic diseases was determined. The financial losses associated with each of the parasitic diseases were estimated in Nigerian Naira (â¦) and US Dollar (USD) considering the market price and weight of viscera condemned. Fasciolosis, hydatidosis, dicrocoeliosis, cysticercosis and oesophagostomiasis were the parasitic disease conditions with fasciolosis (6371/832,001) and cysticercosis (134/832,001) been the most and least prevalent disease conditions respectively. The yearly and monthly prevalence of each disease conditions showed an undefined pattern. There was a significantly difference in the prevalence of the detected parasitic conditions within seasons. The total financial loss associated with these disease conditions was 304,133.82 USD (46,161,433 Nigerian Naira). This study showed that parasitic diseases are of great financial drain to the livestock economy of Nigeria and this study will serve as baseline information on the economic losses associated with parasitic diseases of cattle at slaughter in Nigeria.
ABSTRACT
OBJECTIVE: The current study aimed to determine the prevalence, infection burden, and risk factors associated with the occurrence of gastrointestinal (GI) parasites in different avian species in Ilorin, Nigeria. MATERIALS AND METHODS: This study was conducted in Ilorin, involving 597 fecal samples and GI tracts from a variety of sold and slaughtered avian species. The study was conducted between September 2017 and February 2018. Fecal samples were examined using floatation technique, while the GI tracts were examined for gross helminths and its content were subjected to the direct wet mount examination. Data were analyzed using percentages (descriptive) and the Chi-square (१) test (inferential). p < 0.05 was considered significant for all analysis. RESULTS: Ten GI parasites were detected with Eimeria species (32.83%), Ascaridia galli (30.15%) and Heterakis gallinarum (24.79%) as the most prevalent ones. Multiple parasites co-infection was recorded in all the avian species: broilers (77.78%), layers (33.33%), cockerels (45.16%), indigenous chickens (17.91%), ducks (69.70%), pigeons (94.12%), turkeys (47.83%), and guinea fowls (77.36%). Pigeons (100.00%) and turkeys (95.65%) were the most infected avian species. Age, sex, and avian types were significantly (p < 0.05) associated with the occurrence of GI parasites infection. CONCLUSION: This study gives a reflection of the GI parasites fauna of avian species in Nigeria. The GI parasites are endemic among different avian species in Ilorin, North Central Nigeria. Knowledge on the epidemiology of these parasites is important in instituting a good preventive and control measures against GI parasites, so as to have maximum production and reproduction effects in the poultry industry.
ABSTRACT
AIM: Helminth infections inflict negatively on the production and well-being of animals including poultry. This study was carried out to determine the prevalence, species diversity, intensity, and risk factors associated with the gastrointestinal helminths of intensively raised poultry in Kwara Central senatorial district of Kwara State. MATERIALS AND METHODS: Fecal samples were collected from 502 poultry species from 15 farms. The samples were subjected to floatation and the formalin-ethyl acetate concentration techniques of examination. The intensity of infections was determined using McMaster counting technique. RESULTS: Seven helminth species were detected with Heterakis gallinarum (10.2%) and Ascaridia galli (6.0%) been the most prevalent, while Capillaria species was the least prevalent (0.8%). Physiological status, bird type, production purpose, farm age (years), presence of other animals in the farm, flock size (birds), farm size (acres), housing type, farm type, frequency of anthelmintic use, distance to waste area (meters), level of biosecurity, and frequency of cleaning the pen were the risk factors significantly (p<0.05) associated with the presence of helminth infections. CONCLUSION: This study shows that helminth infections are endemic in the study area, as 66.7% of the sampled farms were infected with one or more helminth species. Findings from this study provide information that will assist in improving the poultry sector in Kwara State, Nigeria in general, for better production and profitability.
ABSTRACT
Coccidiosis is one of the biggest challenges faced by the global poultry industry as the protozoan is found anywhere poultry are reared. Before now, there have been no documents on the intensity and diversity of Eimeria species of poultry in Kwara State. This study aimed to determine the prevalence and intensity of Eimeria species and its species diversity among poultry in Kwara Central, North-Central Nigeria. Five hundred and two fecal samples (from four hundred and seventy two chickens and thirty turkeys) were collected from chickens and turkeys from 15 farms from December 2017 to May 2018. The samples were subjected to floatation technique. Positive samples were further subjected to the McMaster counting technique for determining the intensity of infection. Sporulation of unsporulated oocysts was carried out using 2.5% potassium dichromate (K2Cr2O7), for the purpose of identifying the different Eimeria species. Ninety five (18.9%) of the sampled population, 10 (66.7%) of the 15 sampled farms were positive for Eimeria species. The total mean oocyst per gram was 6325.0. Eight Eimeria species were detected in the study: 7 in chickens and 1 in turkeys. Eimeria tenella was the most predominant among chickens, E. meleagrimitis was the only species detected in turkeys. Age, sex, bird type, physiological status, farm age, farm size (acres), management system, frequency of anthelmintic use, frequency of anticoccidial use, distance to dumping site (meters), level of biosecurity and frequency of cleaning the pen were significantly associated (P < 0.05) with the occurrence of Eimeria infection. It is envisaged that the information obtained in this study will contribute to a clearer understanding of the epidemiology of poultry coccidiosis, for better management protocol which will improve the productivity of the sector in Kwara State and Nigeria.
