Saving feed costs with fat utilisation
There has recently been a slight decrease in the price of feed ingredients in China, but prices are still relatively high compared with the same period last year. Facing such high prices is a real challenge for feed producers. How can they reduce feed costs, while stabilising or enhancing feed production performance?

his article contains a list of cost-reduction solutions from the perspectives of ingredient selection and formula optimisation:
Ingredient alternatives • Maize alternative: energy materials Cereal wheat, barley, sorghum, broken rice, imported corn, cornflour (imported maize with a carrier) and cereal by-product polished powder, rice bran (oil bran), sugar residue, etc. After substitution, some nutritional indicators need to be balanced by adding functional additives (such as enzymes and bile acids). • Soybean oil alternatives: lipid-rich ingredients Lipid-rich ingredients such as rice bran, DDGS, molasses, phospholipids, rice bran oil, palm oil, food scraps, fat residue, meat and bone meal, etc., can significantly contribute to replacing oil. Advantage: make full use of locally available cheap grains, grain by-products and protein according to protein complementation for lower formula costs. Lower feed cost: make full use of locally available material and by-products. Disadvantage: increase risks such as anti-nutritional factors and mycotoxins, decreased palatability and quality of starch and protein sources, affecting feed digestion, absorption rate and intestinal health.
Low protein diet technology The protein level of the feed can be reduced by 2 – 5%. To

make up for this, synthetic amino acids and relatively low priced energy feed ingredients can be added to balance the amino acid level in the diet. Advantage: energy saving and emission reduction, reducing the use of soybean meal. Disadvantage: higher requirements for achieving an amino acid balance.
Protein-energy balance technology Currently, high protein but low energy is common in the feed formula. To get a more reasonable and scientific balance of protein and energy, the crude protein content in the formula will be appropriately reduced for a better protein absorption rate while the fat concentration should be increased. Advantage: reduce the decomposition of non-protein ni- trogen, increase protein deposition rate, as well as feed digestion and absorption utilisation. Disadvantage: the risk of fatty liver and lowere meat quality due to increased crude fat content.
Precise nutrition technology Precisely design nutrition and optimize the formula according to different breed, stage, mode and market needs. Advantage: Make feed nutrition more accurate to meet the needs of animal growth, reduce unnecessary waste, and reduce the cost of formula. Disadvantage: Formulators must carry out a great deal of research. They must be extremely familiar with the farm
