In recent years, with the rising cost of feed, raw materials and artificial, management and transportation, the egg chicken farm bears a lot of cost pressure. In particular, feed costs account for 60% to 80% of the total cost of farming. Its successive years of price inflation, which has already been in the low - profit era of the egg chicken breeding industry is even worse, the farming profit is greatly reduced. In order to solve this problem, many egg chicken farms began to use fermented feed to reduce the cost of laying hens, improve the disease resistance and production performance of chickens, and achieved great economic benefits.
The microbial fermentation feed has the effect of improving feed quality, improving the digestibility of feed and reducing feed cost. Among them, probiotics have the function of promoting growth, anti-diarrhea and enhancing immune function. Here are some of the benefits of fermenting feed.
Benefit 1: easy to absorb.
After hydrolysis of probiotics, soybean meal of feed raw materials can produce a large number of active peptides. These active peptide in feed easy digest, absorb quickly, and can effectively stimulate proliferation to a beneficial bacteria in the intestines, adjust the structure of the microbial flora in the body, more conducive to the whole digestive tract to decomposition and nutrient of the feed utilization.
Benefit 2: inhibit harmful bacteria.
Maintain the balance of intestinal flora.
Beneficial bacteria in the body of fermented feed can inhibit the growth of harmful bacteria such as e. coli, salmonella and reproduce, maintain the balance of intestinal flora, micro ecological environment in the body in a stable, long-term equilibrium state and to avoid the occurrence of intestinal disease.
Advantage 3: supplement the insufficiency of endogenous enzyme.
Increase feed utilization.
Fermentation feed contains a variety of enzymes, which can supplement the insufficiency of endogenous enzyme, promote the digestion of various nutrients in the body, and improve the utilization rate of protein and energy of the egg.
Benefit 4: improved palatability.
Promote the growth and development of chickens.
Fermented feed with lactic acid, vitamins, amino acids and other nutrients, and promote the unknown growth factor, etc., and for generating special fragrance in the fermentation process, improve the palatability of chicken, add chicken feed intake, promote the growth of chicken.
Benefit 5: eliminate anti-nutrition factors.
Untreated soybean meal containing trypsin inhibitor, urease, saponins, goiter factor, gastric bowel to bilge gas factor, antivitamin factors, etc., these substances can hinder layers using the digestion of feed. However, after fermentation, the soybean meal can eliminate these anti-nutrition factors and improve the utilization rate of feed.
Benefit 6: improve egg quality.
Microbial fermentation feed contains lactic acid bacteria and other beneficial bacteria group of lactic acid, acetic acid and other organic acid secretion, can reduce intestinal pH, improving animal intestines of minerals, such as calcium, phosphorus, iron, zinc and the absorption of vitamin D, so as to improve the shell thickness and eggshell strength, eggshell quality is improved. Beneficial bacteria improve the intestinal environment and improve the absorption capacity of carotenoids such as protein and lutein. It was found that the color of HHS unit and egg yolk was significantly increased when microbial fermentation feed was added to the diet.
Calcium and phosphorus are the main minerals that make up the shell and have great influence on the quality of eggshell. Blood calcium is directly involved in the formation of eggshell, which mainly determines the brittleness of eggshell, which is an important factor affecting the quality of eggshell. After adding microbial fermentation feed, the intestinal pH can be reduced, which is beneficial to the absorption of calcium and phosphorus, and improve the concentration of blood calcium and blood phosphorus, thus improving the quality of eggshell.
Benefit 7: optimize the ecological environment.
Bacillus and other beneficial bacteria in the gut can be to utilize the nonprotein nitrogen synthetic amino acids, and produce h2s decomposition enzymes, reduce the waste of the concentration of harmful gases such as ammonia, hydrogen sulfide, reduce environmental pollution, improve the breeding environment.
In conclusion, the advantage of fermented feed is that it can regulate intestinal flora, reduce morbidity, improve feed utilization, improve the quality of egg shell, reduce feed cost, and increase egg production rate. As a result, fermented feed will become more and more popular with egg poultry farms.
