The following is the body of a long article about the fermentation time of green storage feed for your reference:
Green storage feed is a kind of nutritious and palatable feed made by fermenting fresh plant straws, rhizomes, leaves and other raw materials through microbial fermentation technology. Among them, the fermentation time is an important factor, which affects the quality and nutrient composition of the green forage. So, how many days can you feed the green storage feed after fermentation?
First of all, we need to understand the basic principles of green forage fermentation. The fermentation process of green storage feed is to use the action of lactic acid bacteria, yeast and other microorganisms to convert cellulose and hemicellulose in plants into lactic acid, acetic acid and other organic acids, reduce the pH value, inhibit the growth of harmful bacteria, and retain the nutrients in the plant. During fermentation, factors such as temperature, humidity, oxygen, and nitrogen sources can all affect the timing and quality of fermentation.
Under normal circumstances, it takes about 20 to 40 days for green forage to ferment. The exact time depends on factors such as the type of raw material, humidity, temperature and fermentation conditions. In the early stage of fermentation, lactic acid bacteria multiply rapidly, producing a large amount of lactic acid, which lowers the pH value and inhibits the growth of harmful bacteria. As the fermentation time increases, the role of beneficial bacteria such as yeast gradually decreases, and the amount of lactic acid produced gradually decreases. When the amount of lactic acid produced peaks, the fermentation process stops.
During the fermentation process, we need to pay attention to the following:
1.Ensure the humidity and uniformity of raw materials. If the raw material is too dry or too moist, it will affect the effect of fermentation. At the same time, it is necessary to ensure the uniformity of raw materials and avoid the phenomenon of local hypoxia or peroxidation.
2.Control temperature and ventilation. Proper temperature and ventilation conditions can promote the growth of beneficial bacteria and inhibit the growth of harmful bacteria. In general, the suitable temperature range is between 25 and 35. During the fermentation process, the temperature and ventilation of the fermentation room should be checked regularly and adjusted in time.
3.Timely access. When the fermentation time reaches the requirements, the green storage feed should be taken in time. If it is not used for a long time, it will lead to the deterioration of the green forage or the loss of nutrients.
Finally, it should be noted that although green storage feed has the advantages of rich nutrition and good palatability, it is not a universal feed. In the process of use, it is necessary to make reasonable matching and feeding according to the type and growth stage of the animal. At the same time, it is necessary to avoid the use of expired and spoiled green storage feed, so as not to affect the health of animals.
In short, the length of fermentation time depends on the combination of many factors. In the production process, it is necessary to strictly control the humidity, temperature and fermentation conditions of the raw materials and other factors to ensure the quality and nutritional composition of the green storage feed. In the process of use, it is necessary to carry out reasonable matching and feeding according to the type and growth stage of the animal, and avoid the use of expired and deteriorated green storage feed. Only in this way can we better play the role of green storage feed and provide a strong guarantee for the growth and health of animals.
