Livestock production efficiency and resilience
Livestock provide food and livelihoods for one billion of the world's poor, especially in dry and infertile areas where other agricultural practices are less practicable. They play an important multifunctional role in many developing regions providing food, income, draught power for ploughing and transport. They can also provide valuable asset functions, such as collateral for credit, and emergency cash flow when sold in times of crisis.
The livestock sector has expanded rapidly in recent decades and will continue to do so as demand for meat and dairy products continues to grow. An increase of up to 68 percent by 2030 from the 2000 base period has been estimated and this is mainly driven by population and income growth in developing countries (FAO, 2006. World Agriculture: towards 2030/2050). Livestock is also the world’s largest user of land resources, with grazing land occupying 26 percent of the earth’s ice-free land surface, and 33 percent of cropland dedicated to the production of feed (FAO, 2009. The State of Food and Agriculture: Livestock in the Balance). The quick expansion of the sector is a cause of overgrazing and land degradation and an important driver of deforestation. It is also responsible for methane and nitrous oxide emissions from ruminant digestion and manure management, and is the largest global source of methane emissions. However, the carbon footprint of livestock varies considerably among production systems, regions, and commodities, mainly due to variations in the quality of feed, the feed conversion efficiencies of different animal species and impacts on deforestation and land degradation (FAO, 2010. Green House gas emission from the Dairy Sector. A life Cycle Assessment).
Significant productivity improvements are needed for developing countries to meet growing food security and development requirements, while minimizing resource use and GHG emissions from production.

| Multinutrient blocks improve digestibility of fibrous feeds Livestock production in developing countries is largely dependent on fibrous feeds – mainly crop residues and low quality pasture – that are deficient in nitrogen, minerals and vitamins. However, these feedstuffs can be better used if the rumen diet is supplemented with nitrogen, carbohydrate, minerals and vitamins. One of the most suitable methods used to supply animals with the nutrients not found in fibrous feed (in tropical smallholder conditions) is to feed the animals urea and molasses in the form of urea-molasses mineral blocks. These mineral blocks increase productivity of meat and milk production and promote higher reproductive efficiency in ruminant animal species, such as cattle, buffalo, sheep, goats and yak. The success of the technique has resulted in its adoption in over 60 countries (FAO 2007a. The State of Food and Agriculture, Paying Farmers for Environmental Services). |
