Nueve medidas para mejorar la calidad de los piensos y reducir sus costos(І)

In the production of livestock and poultry, the cost of feed accounts for more than 70% of the total cost. As the price of feed raw materials rises, only through scientific feed design, from raw material selection and quality control, selection and combination of antibiotic substitutes, processing technology optimization, feed finished product processing The purpose of reducing feeding costs and improving quality and efficiency can be achieved by systematically and comprehensively considering aspects such as feeding methods, feeding methods and precise nutrition.

  • Raw material price and raw material substitution

In the livestock and poultry compound feed raw materials, corn and soybean meal, as energy and protein feed, account for the largest proportion, of which the amount of corn is about 65%, and the amount of soybean meal is about 20%. As corn continues to rise, wheat, barley, sorghum and other raw materials can be replaced. The protein content of wheat is higher than that of corn, but the energy value is relatively low, and it also contains a lot of non-starch polysaccharides (NSP), so it is necessary to add NSP enzyme, and pay attention to the content of wheat lysine and threonine. Cotton meal, cottonseed protein, rapeseed meal, palm meal, sunflower meal, etc. can replace part of soybean meal according to the actual situation. The acid preparation can improve the solubility of vegetable protein and destroy the double helix structure of starch, which is conducive to the related functions of digestive enzymes. Therefore, special attention should be paid to the application of functional additives when reasonably configuring according to raw material composition, characteristics and price.

  • Configure low-protein diets

Reducing the crude protein level in compound feed by 1% can reduce soybean meal consumption by 2.3%, significantly reducing feed cost. The key point of low-protein technology is to improve the digestion and utilization rate of raw materials and to balance amino acids. After reducing the amount of soybean meal added, lysine, methionine, and threonine should be supplemented accordingly to prevent amino acid levels from decreasing. At the same time, attention should be paid to the optimal balance of essential amino acid ratios. The essential amino acid levels of the mixed meal-based diet should be corrected for ileal amino acid digestibility (pig) or amino acid true digestibility (chicken).

  • Reasonable application of unconventional raw materials

Unconventional raw materials come from agricultural by-products and food industry by-products, and are important feed raw materials. Unconventional feed ingredients have low nutritional value, unbalanced nutritional components, and large variability of nutritional components. In addition, there are poor palatability, most of them contain anti-nutritional factors and other characteristics. When using unconventional feed ingredients, the content of available nutrients should be determined first, and palatability and digestibility should be improved through appropriate processing and changes in physical properties. According to the characteristics of raw materials, the important limiting amino acids are balanced, and the dosage of vitamins and trace elements is adjusted. In addition, it is used in conjunction with special additives, such as the addition of acid preparations and enzyme preparations to improve the nutritional value of the diet and adjust the nutritional balance.
