Improved protein content in animal feed can positively impact productivity, such as the quality and quantity of meat and milk. With the increase in global demand for meat and dairy products, the increase of protein in livestock diets is extremely important. Key to the absorption of protein in livestock diets is the improved digestibility of protein. For protein to be utilised efficiently by livestock i.e. consumed and converted into body protein and resulting in bigger and better-quality meat, certain amino acids need to be present. Thus, to maximise protein deposition in livestock, the required amino acids must also be included in the feed. Amino acids have been added to livestock feed for over 40-years. The most common amino acids added to feeds are Methionine, Lysine, Threonine, and Tryptophan. With the expansion of inexpensive plant-based proteins (soybeans etc.) and increasing demands for meat, plant-based proteins offer an alternative or supplement to amino-acids, contributing to greater efficiency of conversion of proteins from feed to meat. Plant-based proteins also require less monitoring than synthetic additives, but amino acids are often needed to maintain digestibility. Improved livestock productivity and conversion is climate smart because there is more efficient conversion of food to weight gain and less livestock pressure on land, supporting a more efficient value chain.
To effectively implement Improved digestibility, Improved protein content:
- Step 1: Inform farmers of the possible benefits of increased dietary protein in their livestock in order to implement dietary supplements.
- Step 2: Identify a supplement contain the key amino acids - Methionine, Lysine, Threonine, and Tryptophan, in consultation with suppliers and veterinarians.
- Step 3: Added supplements to green plant residue (silage) as guided on packaging or by supplier to increase the efficiency of protein in livestock. Ensure that supplement amounts are suitable for animals and the type of feed being supplemented.
- Step 4: Ensure that supplements sourced will be consistently available from suppliers in the region. These supplements can be purchased at most agricultural shops, including rural areas.
- Step 5: As a low-cost option, farmers can formulate rations specific to their livestock. These rations are only for domestic use and not commercial.
