Synopsis (short abstract) Livestock contribute to food security by supplying essential macro- and micro-nutrients, providing manure and draught power, and generating income. But they also consume food edible by humans and graze on pastures that could be used for crop production. Livestock, especially ruminants, are often seen as poor converters of feed into food products. This paper analyses global livestock feed rations and feed conversion ratios, with specific insight on the diversity in production systems and feed materials. Results estimate that livestock consume 6 billion tonnes of feed (dry matter) annually – including one third of global cereal production – of which 86% is made of materials that are currently not eaten by humans. In addition, soybean cakes, which production can be considered as main driver or land-use, represent 4% of the global livestock feed intake. Producing 1 kg of boneless meat requires an average of 2.8 kg human-edible feed in ruminant systems and 3.2 kg in monogastric systems. While livestock is estimated to use 2.5 billion ha of land, modest improvements in feed use efficiency can reduce further expansion.

    The world's population is expected to surpass 9 billion by 2050. FAO estimates that global food production will need to expand by an estimated 60 percent from current levels. Meeting this massive additional demand will require concerted action on a number of fronts, including efforts to increase the production and consumption of currently under-utilized and under-appreciated foods. Edible insects compromise one such category. Insects offer several advantages as human food. They are extremely ric h in proteins, vitamins and minerals, and at the same time are highly efficient in converting the food they eat into material that can be consumed by humans. This publication provides insight into the collection and farming, processing, marketing and trade of edible insects in Thailand - one of the few countries in the world to have developed a viable and thriving insect farming sector.
