Variations in components of feed materials for livestock production

The local and global demand for livestock products such as milk, beef, and cheese is recorded. This trend is projected to double by 2050 compared to the 2012 levels. Various factors could be attributed to this trend, such as the demand for foods that are rich in protein content. Up to 33% of the protein and 17% of the global kilocalorie intake is currently supplied by the livestock sector for the global human population, which is currently at 7.2 billion people. Improved standards of living and changes in social habits are other reasons. Feed, which accounts for 60 to 80% of the production cost, is a major expense in livestock production. Research has been focused on cost-effective and sustainable feed production over the years. A sustainable livestock industry would heavily rely on precision in feed production, which is vital. In this study, we examined the extent of variation in nutrient composition of feed materials by examining the materials for; a) variation within livestock feed factories; b) similar materials amongst different livestock feed factories; and c) finished livestock feed and the labeled content. Results showed a significant variation of up to 20% in the nutrient content of the livestock feed materials and the finished livestock feed. This variation could cause serious adverse effects on the productivity of the animals and the cost of breeding.
