Minerals and vitamins are often ignored functional nutrients for grazing cattle especially in smallholder farming arears due to lack of technical know-how, convenient forms, availability or affordability.
It is reported that over 70% of farmers in Southern-Africa fail to realise the full value of their livestock due to poor nutrition, as a result animals suffer from chronic hunger, poor growth rate and fertility, low milk production and metabolic diseases.
Namibia, while a beautiful country with five distinct geographical areas, is also the driest country in sub-Saharan Africa. Water is scarce, and the dry climate contributes to limited vegetation, leading to a lack of firewood. As firewood is an important energy source in rural areas, it is a valued resource. Fire has many uses after all; it can, for example, be used for sterilization of mushroom substrates.
