Chicken manure fermentation for high efficiency feed
Posted on
Chicken manure is a nutrient-rich material, containing approximately 18.7% crude protein, 2.5% fat, 13% ash, 11% carbohydrates, 7% fiber, 2.34% nitrogen, 2.32% phosphorus, and 0.83% potassium—values that are significantly higher than those found in pig manure. In fact, chicken manure has 4.1 times more nitrogen, 5.1 times more phosphorus, and 1.8 times more potassium compared to pig manure. This makes it an extremely valuable resource for both agriculture and animal feed production.
Using fermented chicken manure as a feed or fertilizer not only helps reduce waste but also provides a sustainable solution for farmers. The fermentation process breaks down the organic matter, making it safer and more digestible for animals. It also enhances the nutrient availability, which can improve livestock health and growth.
To turn chicken manure into usable feed, a simple fermentation method can be applied. First, collect fresh chicken droppings and remove any soil or debris. Then, crush the manure and mix it with green materials in a 3:1 ratio (manure to green matter). Add a microbial culture agent specifically designed for composting or fermentation, such as "Gold Bait" or similar products.
Next, add water until the mixture holds together when squeezed in your hand without dripping. The texture should be moist but not wet. Once the mixture is ready, compact it in a container or pit, then cover the top with a 2 cm layer of bran, rice husk, or grass powder. Finally, seal the whole setup with a plastic sheet to create an anaerobic environment.
Fermentation typically takes 3 to 5 days, depending on temperature and humidity. After this time, the manure will become soft, fragrant, and much more palatable. It can then be used as a supplement for pigs, fish, or even poultry, offering a cost-effective and environmentally friendly alternative to traditional feed sources.
By properly fermenting chicken manure, farmers can turn a waste product into a valuable asset, contributing to both economic and ecological sustainability.
Feed additive enzymes Simple classification of feed enzymes:
1.endogenous enzymes, refers to the animal body can secrete digestive enzymes, the main function is to digest the nutrients in the feed used to improve the digestibility of feed; The digestive system of young animals is not perfect, and the digestive enzymes secreted by the body are insufficient. In particular, a large amount of endogenous enzymes should be added to the feed based on plant raw materials to solve the digestive problems. Endogenous enzymes generally refer to protease, amylase, lipase and so on.
2. Exogenous enzymes refer to the enzyme preparations that animals cannot secrete autonomously and must be added. The main function is to degrade the anti-nutrient factors of plant raw materials, non-starch polysaccharides that hinder the release of nutrients and react with the contact of endogenous enzymes, such as cell walls, and non-starch polysaccharides that bring negative effects; Common are phytase, xylanase, glucanase, cellulase, mannanase, galactosidase, etc.
3.functional enzymes, mainly use its catalytic function to achieve the processes and products we need, such as glucose oxidase, a brief overview is the catalytic process with glucose to consume oxygen, produce gluconic acid and hydrogen peroxide, Reduce the PH value of the gut, and use its strong oxidation to alleviate mycotoxin poisoning and protect the health of the digestive system, improve immunity and other functions; In addition, there are catalase, lysozyme and other related products, the specific function is not this unnecessary
