High-nutrition environment-friendly feed and preparation method thereof

Abstract

The invention discloses a high-nutrition environment-friendly feed, which comprises a basic nutrient and traditional Chinese medicine mixed powder, wherein the basic nutrient comprises potato residues, bran, apple residues, white distillers grains, beer distillers grains and bone meal; the traditional Chinese medicine mixed powder comprises radish seeds, pinellia tuber, polygonum multiflorum, Chinese violet, dried orange peel, medicated leaven, Poria, Semen Armeniacae Amarum, Fructus Crataegi, and Radix Astragali; the invention further discloses a preparation method of the high-nutrition environment-friendly feed, which comprises the following steps: 1) uniformly mixing the basic nutrient and the traditional Chinese medicine mixed powder to prepare the high-nutrition environment-friendly feed; 2) uniformly mixing candida utilis, aspergillus niger, xylinase, paecilomyces and bacillus subtilis to prepare mixed strain liquid; 3) adding ammonium sulfate and mixed bacterial liquid into thehigh-nutrition environment-friendly feed, and then adding the ammonium sulfate and the mixed bacterial liquid into the high-nutrition environment-friendly feed, and fermenting at the temperature of 23-29 DEG C for 2-4 days; 4) drying the fermentation product at the temperature of 50-55 DEG C; the high-nutrition environment-friendly feed can improve the utilization rate of feed, reduce the discharge amount of nutrient assemblys in excrement, improve the immunity of pigs and promote the growth of pigs.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a high-nutrition and environment-friendly feed and a preparation method thereof. Background technique [0002] At present, the pig industry has developed rapidly and has become an important part of my country's animal husbandry. The problem of environmental pollution caused by pig farming is becoming more and more serious. [0003] During the breeding process, certain drugs are usually added to the feed to promote the digestion and absorption of pigs or improve the immunity of pigs, and most of these additives are drugs or nutrients with high nutritional content, such as antibiotics and some additives, etc. The high copper, iron, zinc and other trace elements in the feed, as well as antibiotics and additives are not easy to digest, and most of the ingredients are excreted in the form of feces and urine, which makes the pig manure smell bad, and at the same time produces harmful gas...

Problems solved by technology

[0003] During the breeding process, certain drugs are usually added to the feed to promote the digestion and absorption of pigs or improve the immunity of pigs, and most of these additives are drugs or nutrients with high nutritional content, such as antibiotics and some additives, etc. The high copper, iron, zinc and other trace elements in the feed, as well as antibiotics and additives are not easy to digest, and most of the ingredients are excreted in the form of feces and urine, which makes the pig manure smell bad, and at the same time produces harmful gases such as ammonia and hydrogen sulfide , affecting air quality; secondly, manure, as an organic fertilizer, can play a role in changing soil fertility, but due to the increase in the residual proportion of trace elements and additives in pig manure, the soil composition also changes accordingly, resulting in damage to the soil structure
