Technology for using alternative unconventional feed ingredients in poultry production (I)

Research shows that different combinations of raw materials can strengthen the complementarity between raw materials, make up for the nutritional imbalance between raw materials, reduce the content of toxins or anti-nutritional factors, increase the level of nutrients, ensure or even improve the production performance of livestock and poultry, reduce costs and increase efficiency, It has good prospects for improving feed fermentation quality and fermentation efficiency.    

For example, Zhang Yanming et al. used cotton meal, DDGS, rapeseed meal and corn gluten meal as the main raw materials to prepare different compound protein feeds to replace soybean meal. They found that the feed palatability was good and the production performance of laying hens was not significantly affected. Calculated based on the feed price during the same period, the compound protein The raw material cost of feed is 12% -14. 1% lower than that of soybean meal.    

Research by Liang Haichao and others found that using compound mixed meal (cottonseed meal, rapeseed meal and peanut meal) to replace 20%-30% of soybean meal in the diet has a negative impact on the production performance, intestinal barrier function and intestinal flora of laying hens during the laying period. No adverse effects on the structure.

Cassava residues with high crude fiber content have been widely used as feed materials for ruminants. However, because they contain crude ash and have high crude fiber content, their palatability is poor, which limits the use of cassava residues in monogastric animals.    

Waterfowl have the advantages of strong stress resistance and tolerance to rough feeding, and have strong adaptability to cassava residue and other conditions.    

Research shows that a reasonable combination of corn, cassava and rice replaces part of the corn as feed raw materials, and has no significant impact on the nutrient digestion, slaughter performance, growth performance and blood indicators of geese, confirming the practical application of appropriate dietary mix in waterfowl production. feasibility.    

The recommended addition amounts of common alternative unconventional feed ingredients in poultry breeding are shown in Table 2, which can provide a reference for their reasonable combination.
