Liquid fertilisers, liquid animal feeds or components thereof are formulated using by-products from other production. One by-product is slaughterhouse blood. This may be incorporated into sprayable liquid fertiliser. Another by-product is a liquid plant extract obtained from crushing and pressing plant material such as grass. The liquid is utilised in liquid animal feed supplements or components or liquid fertilisers in each case in admixture with other nutrients. A liquid animal feed component may be mixed with an edible solid which absorbs it, giving a solid feed. |
