Antibiotic-free and low-protein mulberry tree fermented feed for fattening pigs and preparation method thereof

Abstract

The invention discloses an antibiotic-free and low-protein mulberry fermented feed for fattening pigs, which is prepared from the following raw materials: corn, mulberry fermented material, buckwheat flour, soybean meal, cottonseed protein powder, grape seed meal, Corn germ meal, mulberry leaf powder, stone powder, 0.5% compound multidimensional and compound multimineral for fattening pigs, licorice powder, feed grade sodium chloride, Acremonium acremonium culture, calcium hydrogen phosphate, encapsulated cysteamine, picolinic acid Chromium, medical stone, expanded linseed, compound organic iron mixture, proteinase K, lactase, lysine, methionine, threonine, tryptophan, valine, sodium glutamate, and its preparation method is provided . The beneficial effects of the present invention are as follows: the present invention adopts mulberry fermented feed, which can improve the utilization rate of nutrient substances of feed raw materials, passivate anti-nutritional factors, multiply and enrich beneficial microorganisms in large quantities, and promote the improvement and improvement of pork quality, and its formula is reasonable , low cost, energy saving and environmental protection, obvious growth and fattening effect, healthy meat quality and good flavor.

Description

technical field [0001] The invention relates to the technical field of animal feed preparation, in particular to an antibiotic-free and low-protein mulberry fermented feed for fattening pigs and a preparation method thereof. Background technique [0002] Low-protein diet under amino acid balance mode is one of the effective means to increase nitrogen utilization and reduce nitrogen emission. The lack of protein resources and the appearance of crystalline amino acids make it necessary and feasible to study low-protein diets under the amino acid balance mode. Studies have shown that properly reducing the protein level of pig diets while balancing lysine, methionine, threonine and tryptophan can significantly reduce urinary nitrogen emissions and improve nitrogen use efficiency. Reduce the crude protein level of the diet by 2-3% according to the NRC recommended standard, and at the same time add suitable synthetic amino acids to meet the animal's demand for amino acids. The lo...

Problems solved by technology

Although adding antibiotics to pig feed can significantly improve pig production performance and utilization of nutrients, it will also bring problems such as antibiotic residues in pork products and environmental pollution.
