AI Technical Summary

Technical Problem

Existing soybean meal-free feeds have problems with anti-nutritional factors, feed physical properties, and electrolyte balance in laying hen farming, which affect the health of laying hens and egg quality.

Method used

Wheat flour, barley flour, cottonseed meal, and glutamic acid residue are mixed, granulated, and then crushed. Combined with corn, sunflower meal, corn gluten meal, chili residue, granular limestone, dicalcium phosphate, soybean oil, and compound enzymes, the cation-anion difference in the diet is regulated to prepare soybean meal-free feed for laying hens. The compound enzyme degrades gossypol, and the particle size and ion balance are controlled.

Benefits of technology

It effectively replaces soybean meal, increases eggshell thickness, reduces egg breakage rate, improves laying hen production performance, and ensures hen health and egg quality.

Abstract

The application belongs to the technical field of animal feed, and particularly relates to an egg-laying chicken feed without soybean meal, and a preparation method and application thereof. The method comprises the following steps: S1, mixing wheat flour, barley flour, cottonseed meal and glutamic acid residue, crushing the granules to obtain broken material; and S2, mixing the broken material with corn, sunflower meal, corn gluten meal, pepper residue, granular stone powder, calcium hydrogen phosphate, soybean oil, compound enzyme, sodium chloride, sodium bicarbonate, egg methionine, lysine sulfate and threonine to obtain the egg-laying chicken feed without soybean meal. The application provides comprehensive essential amino acids, especially limiting amino acids such as lysine, egg methionine and threonine, by the synergistic combination of cottonseed meal, sunflower meal, corn gluten meal and glutamic acid residue, so as to meet the nutritional requirements of egg-laying chickens. The application granulates at a temperature of 75-85 DEG C, effectively degrades free gossypol in the cottonseed meal, reduces the content of free gossypol to less than 30 mg / kg in the finished feed, and eliminates the adverse effects on the health of egg-laying chickens.
