Effective ways to reduce the cost of feed under Covid-19 conditions


With the epidemic spreading around the world, many countries have reported the need to restrict the export of grains and feed industries are facing huge challenges. Reducing the cost of feed is a difficult problem that needs to be solved urgently.

1. Feed processing Feed mills should concentrate their production output to 2-3 days.


2. Raw material procurement Adopt best value procurement principles and rely on technol- ogy to analyse the value of various raw materials, and in- crease the procurement and use of valuable raw materials.


3. Feed formula The cost of feed ingredients accounts for about 95% of the cost of feed, so adjusting the feed formula has a large impact on cost. There are several options for cost saving with the broiler diet formula:


3.1 Accurate nutrition technology Make feed nutrition more accurate to meet animal mainte- nance and growth needs. However, it is necessary to have an

in-depth understanding of the nutritional requirements of the species to be bred and an accurate grasp of the actual nutritional indicators of the raw materials used.


3.2 Raw material substitution technology Use some miscellaneous meal to replace conventional animal and plant protein. For example, use sunflower meal, DDGS and/or peanut meal instead of meat and bone meal and soy- bean meal in the original formula. Make rational use of the complementarity between protein materials. However, the risk of adverse factors such as anti-nutritional factors and my- cotoxins is increased and protein quality and feed palatability may well be reduced.


3.3 Low-protein-diet technology Reduce the nutritional level of feed protein by 0.5-1.0, add appropriate amount of synthetic amino acids to make up for the lack of amino acids, and reduce the use of soybean meal, meat and bone meal and other raw materials.


3.4 Additive replacement technology Reduce the use of additives and optimise the effect of each additive. However, it is necessary to fully grasp the process and efficacy of each additive.

3.5 Technology to improve fat utilisation Add additives to improve fat utilisation and appropriately re- duce the metabolic energy level of the formula. Maximise the use of fat nutrition and increase the use and absorption of fat-soluble substances such as fat-soluble vitamins, and opti- mise the use of space to reduce costs.


4. Related case sharing Enterprises need to increase the use of unconventional pro- tein materials. Animal health specialists at Lachance Animal Nutrition adjusted the feed formula for the later nutritional needs of broilers and increased the use of cotton meal and peanut meal. Adding bile acids to ensure the same metabolisable energy can reduce costs by US$ 2.5 per tonne (Table 1).
