The advantages of litter plus super-enzyme broiler chicken are that it can purify the air in the house and reduce the odor compounds in chicken manure - hydrogen sulfide, skatole (methyl hydrazine), aliphatic aldehydes, thiols and amines. The harm of chickens is to prevent the occurrence of upper respiratory tract disease in broilers. Second, it can inhibit the reproduction of harmful bacteria, eliminate parasites and eggs, prevent moldy of litter, reduce the incidence of colibacillosis and coccidiosis; save disinfection drugs and reduce feeding costs. Improve the survival rate of broiler chickens.
Treatment and use of litter The litter of flat broiler should generally be cleaned, mold-free straw, and crushed. Generally, the pulverization should be coarser, and the sieve hole of the pulverizer should be 15-20 mm. When using, the straw powder is first laid on the floor 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 1-1.5 kg of super-enzyme and bran mixture on the surface of the grass powder per square meter. After 5 weeks of age, if the chicken manure is too much to form agglomerates, you can use the iron shovel to loosen, or you can add a layer of glutinous powder on it, and sprinkle a mixture of super enzyme and bran.
Chicken manure "recycled feed" production method After the chickens are all out of the bar, the chicken manure litter is completely removed, placed on the hardened ground, and the larger agglomerates are shredded with shovel and mixed immediately, and the fermentation is immediately accumulated. Different stacked fermentation methods can be employed depending on the amount of fermentation. When the amount is large, it can be stacked into a square shape, and the height is preferably 1.2-1.5 meters. When the amount is small, it can be piled up in a round shape.
Do not over-extend when stacking, and do not flatten the surface to ensure the permeability of the ferment. There are more than 100 kinds of beneficial bacteria in super enzymes, such as aerobic bacteria, anaerobic bacteria, photosynthetic bacteria, etc. Most of them start from 16 °C, and the most active cells are 45-60 °C, so the fermentation time is 45-60 °C. It should be relatively long. When the temperature reaches 65 °C, spread the ammonia gas, increase the contact surface with oxygen and light, spread the thickness of 15-20 cm, and accumulate again for about 10-12 hours. In principle, the surface layer is piled up to the mash and fermented. Flat, stacked. This is repeated two or three times. When the reconstituted beverage is dark red and emits a sour scent, it indicates that it has been fermented and can be compacted with a plastic sheet for feeding.
Problems that may occur during fermentation 1. When the piles of chicken manure are piled up in the fermentation, the surface of the pile is long white peony. This is due to the hyphae produced by the proliferation of actinomycetes. These hyphae are not harmful to livestock and poultry, and have high nutritional value. The disadvantage is that the palatability is slightly worse and can still be used for feed. 2. Fermentation is not good or not fermented, which means smelly and black. There are several reasons for this: First, the temperature is too low, and it is not suitable for the breeding of beneficial bacteria. It should be considered to heat up indoors, or cover plastic sheets and grasshoppers to increase temperature. Second, there is no time to turn the surface of the lack of oxygen, and it can be turned over several times in time. Third, the humidity is too large or too small, you can consider adding water or adding dry matter to adjust, so that the humidity is controlled between 35-55, that is, the hand is pinched into a group but not dripping.
The feeding method of the regenerated feed and the suitable feeding and fermenting chicken feces litter (ie, the regenerated feed) have the acidity and aroma of the livestock and poultry, can stimulate the secretion of the digestive juice of the livestock and poultry, and improve the digestibility and palatability. However, any feed that feeds livestock and poultry has an adaptation process. It must be noted that on the basis of the original feed, from pigs to pigs, the pigs gradually adapt. Practice has proved that the adaptation period of pigs is generally 10-15 days. That is to say, it is necessary to carry out the cultivating for 10-15 days in order to add the "recycled feed" to the appropriate proportion. The appropriate proportion of adding pigs is 50%, and the suitable proportion of empty sows and pregnant sows is 80%-90%. The proportion of sows in the first month of lactation and lactation is 40%-50%, according to the above ratio. Feeding, fat pig skin red hair, fast growth, strong disease resistance. The sow has normal estrus, high litter rate, and the piglets are well-balanced and not diarrhea.
