Insects in ruminant nutrition as an urgent measure in the light of the scarcity of raw feedstock

Abstract

Global population growth will lead to an increase in demand for animal-based foods, such as meat and milk from ruminants, which will require restructuring some of the components of the ration (Castillo et al., 2017; Van Huis, 2020). This need is controversial for several reasons: 1) contribution to the depletion of environmental resources; 2) competition of protein sources with human food or fuel increasing prices for farmers, minimising farm profitability
