The Poultry Association of Zambia has identified a significant increase in the cost of stock feed in the local market, which is being driven by a rise in the demand for soya beans, maize, and sunflower. The association has also pointed out that farmers from other countries are taking advantage of the depreciation of the kwacha to buy soya beans at cheaper prices in Zambia. The Association expected stability in the prices of soya cake and soya beans after a bumper harvest this year, but instead, the prices have surged by almost 173%.
