The advantages of litter plus super-enriched broiler chickens is to clean the house air and reduce the odor compounds in chicken manure - hydrogen sulphide, skatole (methyl hydrazine), aliphatic aldehydes, thiols and amines. The hazards of chickens prevent the occurrence of upper respiratory tract disease in broilers. Second, it can inhibit the reproduction of harmful bacteria, eliminate parasites and eggs, prevent mildew of litter, reduce E. coli disease, coccidiosis rate; save disinfectant drugs, reduce feeding costs, and improve the survival rate of mountain broilers.
The processing and use of litter The litter for raising broilers should generally be cleaned, straw with no mildew, and crushed. When crushing, it should be generally coarse, and the sieve of the crusher should be 15-20mm. When used, the straw powder is first spread on the ground of the chicken house, and the thickness is generally 15-20 cm. Mix the super enzyme and bran in a ratio of 1:15-20. Then, sprinkle a mixture of 1-1.5 kg of super-enzyme and bran per square meter of grass powder and raise the chicken. After 5 weeks of age, if the chicken droppings form an agglomerate, you can use iron shovels to shake loose, or add a layer of lotus root flour on top, and sprinkle the super enzyme and bran mixture in proper amount.
After the chickens are all slaughtered, all the litter of chicken litter is cleared out and placed on the hardened ground. The larger agglomerates are crushed and mixed well with mash, immediately piled and fermented. Different stacking fermentation methods can be used depending on the amount of fermentation. When the volume is large, it can be stacked into a square and the height is preferably 1.2-1.5 meters. When the amount is small, it can be piled into a round heap shape.
Do not press too hard when stacked, and do not flatten the surface to ensure breathability of the fermented material. There are more than 100 kinds of beneficial bacteria in super-enzymes, including aerobic bacteria, anaerobic bacteria, and photosynthetic bacteria. Most of them grow from 16°C and are most active at 45-60°C. Therefore, the fermentation time is 45-60°C. To be relatively long. When the temperature reaches 65°C, spread the ammonia gas, increase the contact surface with oxygen and light, spread the thickness to 15-20cm, and store it again for about 10-12 hours. In principle, the surface layer will be piled and fermented. Flat and stacked. This repeated two or three times, when the rejuvenating beverage showed a deep red color and emitted an acid scent, it showed that it had been fermented well, and it could be tightly compacted with a plastic cloth for feeding.
Problems that may arise during fermentation
1. Piles of chicken manure mats are piled up during the fermentation process. The surface layer is the white peony which is produced by the large number of actinomycetes. The hyphae are not harmful to livestock and poultry and have high nutritional value. The disadvantage is that the palatability is slightly poor. Some can still be used for feed.
2, the fermentation is not good or does not ferment, refers to the smell, the color becomes black. This situation is caused by the following reasons: First, the temperature is too low and it is not suitable for the propagation of beneficial bacteria. It should be considered to increase the temperature in the room, or to increase the temperature with plastic sheeting and grasshoppers. The second is that there is no time to flip the surface oxygen, timely turn several times on it.
3, the humidity is too large or too small, you can consider adding water or add dry matter to adjust, so that the humidity is controlled between 35-55, that is, the hand into a group but not dripping.
The method of feeding the regenerated feed and the suitable amount of fermented chicken manure (ie, the regenerated feed) that is suitable for feeding, although having the acid and aroma of livestock and poultry, can stimulate the secretion of the digestive juice of the livestock and poultry, and improve the digestibility and palatability. However, there is an adaptation process for any feed to feed livestock and poultry, and it is necessary to pay attention to the gradual increase in the number of pigs fed on the basis of the original feed. Practice has proved that the adaptation period of pigs is generally 10-15 days. This means that 10-15 days of paddling must be carried out before adding "renewable feed" to the appropriate proportion. The appropriate proportion of pigs is 50%, and the appropriate proportion of empty sows and pregnant sows is 80-90%. The suitable proportion of pre-natal and lactating sows is 40-50%, and they are fed according to the above proportions. The fat pig skin is red and light, fast growing, and strong in disease resistance. The sows have normal estrus and high litter size. The piglets are well-balanced and robust and do not dilute.
Unlike fresh fruits, fruit powder is made by advanced technologies so to extend the shelf life and versatility. We have Freeze Dried Fruit Powder and spray dried fruit powder.
