Profitability analysis of smallholder aquaculture farms: the case of Lagos State, Nigeria
(2022-04-06)

The domestic fish production is short of the consumption demand despite the vast potentials in the fishery sector. Harnessing these potentials rightly will help to increase employment and increase food fish production and availability. It is clear given the importance of aquaculture in fish production that efforts must be made to encourage entrepreneurs to go into the business. Many have cast doubts on the profitability ...

The ‘fine balance’ of West African savannah parklands: biomass generation versus firewood consumption
(2022-03-15)
In sub-Saharan Africa, the long-awaited fuelwood gap, resulting of the unbalance between a declining supply of firewood and the increasing demand of households, remains a latent social-ecological challenge. As its quantitative basis remains elusive, we have assessed agroforestry parklands, assumedly main providers of firewood, and firewood consumption in Dassari, Benin and Dano, Burkina Faso, both in the West African savannah. Data collected included botanical inventories, tree biomass estimations, householders’ ...

Effects of Petiveria alliacea (guinea hen weed) leaf extract on fermentation parameters, nutrient digestibility and faecal worm egg count in growing West African dwarf goats
(2022-03-21)
Medicinal plants are used in animal feeding as natural antimicrobial to improve nutrient utilisation and health status of animals. This study assessed the effects of varying concentration of Petiveria alliacea leaf extract (PLE) on fermentation parameters, nutrient digestibility, nitrogen utilisation and faecal worm egg count of growing West African dwarf goats. Twenty- four (24) growing West African dwarf bucks with average body weight of 8.50 ± 0.55 kg were divided into four treatment groups with six bucks each ...
