Application of Microorganisms in Aquaculture
First, the composition of biological feed
The biological feed is mainly composed of four bacterial strains and twenty-four beneficial microorganisms. It contains a variety of enzymes: amylase, protease, lipase, cellulase, lactase, maltase, urease, alcoholic enzymes, dozens of different types of enzymes. The fermentation broth used was soybean, corn, sorghum, rice bran, cotton aphid, rapeseed meal, phospholipid powder, whey powder, humic acid and more than twenty kinds of raw materials.
Second, the characteristics of biological feed:
1. Maintain the balance of intestinal flora to prevent gastrointestinal diseases.
As soon as biological feed enters the intestines of livestock and poultry, it rapidly reproduces and quickly assumes a dominant position, suppressing the reproduction of harmful bacteria and keeping livestock and poultry in a healthy state.
2. Biofeeds can produce organic acids, bacteriocins, and dipicolinic acid during metabolic processes in livestock and poultry, providing a conducive breeding environment for living organisms, and inhibiting the reproduction of pathogenic bacteria, improving the animal's ability to adapt to the environment, and biological feeds. In the process of digestion, a large amount of lactic acid, acetic acid, propionic acid, bacillus acid, pyridine dicarboxylic acid and other substances are produced, which can keep the animal's gastrointestinal environment acidic, inhibit the reproduction of pathogenic bacteria, activate various digestive enzymes, and increase the digestibility of feed. .
3. During the digestion process of biological feed, a large number of beneficial organisms can metabolize, transform, and restore ammonia, guanidine, nitrite, peroxides, free radicals, and various toxins in the gastrointestinal tract of animals. In order to reduce the accumulation of these substances in the body, beneficial microorganisms can also use the above substances to metabolize and synthesize the nutrients of the animal's body, turning waste into treasure.
4. During the decomposition of biological feed in animals, amylase, cellulase, phytate, glucoamylase, and protease can be produced by beneficial microorganisms, which can increase the utilization of feed.
5. Probiotics in biological feed produce some coenzymes and vitamins, which not only increase the absorption of various trace elements in animals, but also increase the leukocyte phagocytosis index and lymphocyte ratio in animals, thereby enhancing the animals' immunity and disease resistance. ability.
6. Livestock and poultry products raised by biological feed are delicious. The enzymes produced during the digestion process can effectively reduce the bad odors in the feed, so that the bad taste can not be deposited into the animal body, truly green organic natural animal products .
Third, the effectiveness of biological feed
1, disease prevention and disease, enhance the body's immune system.
Animals fed with biological feeds have a greatly reduced incidence of disease, the incidence rate can be reduced by more than 50%, the gastrointestinal diseases can be reduced by more than 85%, and the survival rate can be increased by more than 50%. This is particularly effective for the diarrhea of ​​chicks and piglets, and the efficiency can be improved. 95-99%.
2, accelerate the growth of animals, shorten the feeding cycle. Animals fed with biological feeds grow fast. Daily gains of broilers and pigs increase by 5-10%, egg production can increase by 5-10%, milk production can increase by 10-15%, and milk fat percentage increase by 0.1-0.3%. percentage point.
3, to improve the animal's digestion and absorption utilization of feed, reduce nutrient losses, reduce feed and meat ratio, increase feed remuneration 5-10%.
4. After adding biological feed to feed, no antibiotics and chemical drugs may be added. There is no drug residue in animal products, which is in line with organic food and export standards.
5. Reduce the generation of harmful gases and toxic substances, eliminate odor of animal faeces, purify the ecological environment, and feed livestock and poultry that “combine micro-organismsâ€. The odor and ammonia of the feces are significantly reduced, and the odor in the livestock house disappears. The ammonia in the air is eliminated. The gas concentration is reduced by more than 80%, and insect pests such as fly maggots are reduced, which greatly improves the feeding environment, is conducive to animal health, and promotes animal growth.
6, after the addition of biological feed, feed can not add antibiotics, promote growth enzyme preparations, probiotics, etc., directly reduce the cost of feed, at the same time because the increase in feed efficiency reduces the feed ratio, the ratio of eggs to feed, reduce feed wastage, save Feed 8-12%, so that the cost of farming is greatly reduced.
7. The use of biological feed can greatly improve the economic benefits of farmers, prevent various diseases such as disease prevention, disease resistance, growth promotion, and feed cost reduction, and can increase the profit of farmers by 25-50%. 1:2-5.
