Abstract
It is anticipated that a 50% to 70% increase in food productivity will be needed to feed 9 billion people by 2050. Livestock provide for about 33% of human protein consumption and 17% of total calories (FAO, 2018). The demand for livestock products is estimated to more than double in the next 20 yr, as a result of urbanization, economic growth, and a change in consumption patterns in low- and middle-income countries (LMICs).
