Mixed-meal fermented concentrated feed for weaned pigs

Abstract

The invention aims to design a mixed-meal fermented concentrated feed for weaned pigs, which has the advantages as follows: mixed meal resources are used fully, the body immunity of weaned pigs is enhanced, the diarrhea rate is reduced, the production performance of weaned pigs is improved, and the feed does not contain antibiotics. The invention adopts the technical schemes as follows: the feed is composed the following raw materials: water, puffed dry sweet potato flour, peeled puffed full-fat soybeans, puffed peanut meal, broad bean gluten protein, fish meal, puffed blood meal,casein, lactose, glucose, fish oil, a fermentation bacteria preparation, choline chloride, lysine, tryptophan, threonine, sodium humate, fructo-oligo saccharide, calcium carbonate, calcium hydrophosphate, glycine betaine, vitamin premix, table salt, copper sulfate, zinc sulfate, manganese sulfate, potassium iodide, sodium selenite and the like. The feed provided by the invention is high in safety; the utilization ratio of mixed meal is high and digestive absorption is good; the body immunity of weaned pigs is improved obviously and diarrhea rate is increased; the production performance of weaned pigs is improved obviously.

Description

Technical field: [0001] The invention relates to a concentrated feed, in particular to a weaned piglet fermented concentrated feed. Background technique: [0002] Weaned piglets refer to piglets that are weaned at the age of 3-5 weeks to 10 weeks after birth. Weaning is another strong stress for piglets since birth. The first is the nutritional change, from eating warm liquid breast milk to eating solid raw and dry feed, which is prone to dyspepsia diarrhea; Life is changed to a completely independent life; the third is the change and migration of the living environment, from the delivery room to the breeding house, accompanied by regrouping; the fourth is that they are susceptible to infection by pathogenic microorganisms and disease. Weaned piglets are in the stage of rapid growth and development. On the one hand, they have a particularly large demand for nutrition, and on the other hand, the function of their digestive organs is not perfect. Therefore, enhancing the dige...

Problems solved by technology

Due to the shortage of high-quality protein feed resources such as soybean meal and fish meal, the price of traditional concentrated feed for weaned piglets is high, and the efficiency of pig breeding is low; antibiotics, chemically synthesized drugs and heavy metals have been used in weaned piglet feed for a long time, causing the drug resistance of pathogenic bacteria to continue. Enhanced, resulting in continuous increase in the effective addition of antibiotics, chemical synthetic drugs and heavy metals in feed, resulting in low autoimmunity of weaned piglets, seriously affecting the subsequent production performance of growing and finishing pigs, while antibiotics, chemical synthetic drugs and heavy metals and other feed The extensive use of additives also causes serious pollution to the environment and directly poses a threat to human health
