Prevalence of ticks on indigenous breed of hunting dogs in Ogun State, Nigeria

Ticks are haematophagous arthropods that are important vectors of diseases of animals and humans, many of which are zoonotic, thus predisposing humans, including hunters to risk. The present study was conducted to assess the prevalence of tick infestation among hunting dogs with the aim of determining the danger which the presence of ticks portends, bearing in mind that hunting dogs are kept by the duo of rural and urban dwellers. A total of one hundred and nine (109) hunting dogs were sampled from nineteen (19) different locations in the State. The age, weight and sex of the dogs were noted and recorded as variables. The dogs were thoroughly examined for ticks and other ectoparasites which were collected into properly labelled plastic containers and were transported to the laboratory for identification. Chi-square test was used to compare the prevalence of tick infestation between recorded variables. Significance level was set at p = 0.05 or less. The overall prevalence of tick infestation in the 109 hunting dogs was 56%. The tick prevalence in the male dogs (66.7%) and that in the female dogs (51.9%) was not significantly (p> 0.05) different. Also, tick prevalence in young dogs (53.8%) and adult dogs (62.1%) was not significantly (p>0.05) different. There was a significant difference in the prevalence of tick infestation from urban and rural locations (p<0.05). Of the 352 ticks harvested from the hunting dogs, Rhipicepalus sanguineus constituted 68.2%, Haemaphysalis leachi leachi, 30.6%; and Ambylomma variegatum, 1.21%. The education of the hunters and other persons in close contact with dogs is required for the control of ectoparasites.Keywords: Hunting dogs, Indigenous, Nigeria, Prevalence, Tick

From cassava to gari: Mapping of quality characteristics and end-user preferences in Cameroon and Nigeria

User's preferences of cassava and cassava products along the value chain are supported by specific root quality characteristics that can be linked to root traits. Therefore, providing an evidence base of user preferred characteristics along the value chain, can help in the functional choice of cassava varieties. In this respect, the present paper presents the results from focus group discussions and individual interviews on user preferred quality characteristics of raw cassava roots and the derived product, gari, ‐ one of the major cassava products in Sub Saharan Africa ‐ in major production and consumption areas of Cameroon and Nigeria. Choice of cassava varieties for farming is mainly determined by the multiple end‐uses of the roots, their agricultural yield and the processing determinants of roots that support their major high‐quality characteristics: size, density, low water content, maturity, colour and safety. Processing of cassava roots into gari goes through different technological variants leading to a gari whose high‐quality characteristics are: dryness, colour, shiny/attractive appearance, uniform granules and taste. Eba, the major consumption form of gari in Cameroon and Nigeria is mainly characterized by its textural properties: smoothness, firmness, stickiness, elasticity, mouldability. Recommendations are made, suggesting that breeding will have to start evaluating cassava clones for brightness/shininess, as well as textural properties such as mouldability and elasticity of cassava food products, for the purpose of supporting decision‐making by breeders and the development of high‐throughput selection methods of cassava varieties. Women are identified as important beneficiaries of such initiatives giving their disadvantaged position and their prominent role in cassava processing and marketing of gari
