The advantages of litter and super enzyme flat broiler
The first is to purify the air of the chicken house and reduce the harm to chickens caused by the odor compounds in chicken manure - hydrogen sulphide, skatole (methyl hydrazine), aliphatic aldehydes, thiols and amines, and prevent the upper respiratory tract disease in broilers. occur. The second is to inhibit the reproduction of harmful bacteria, eliminate parasites and eggs, prevent moldy bedding, reduce E. coli disease, coccidiosis rate; save disinfection drugs and reduce feeding costs. Improve the slaughter rate of broilers.
Disposal and use of litter
Brooders for raising broilers should generally be clean, 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.
Chicken manure "recycled feed" manufacturing method
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 piled up during the fermentation process to pay the material surface Changbai wolfberry, this is due to the proliferation of actinomycetes mycelium produced, the hyphae harmless to livestock and poultry, high nutritional value, the disadvantage is poor palatability Some can still be used for feed. 2. 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. Third, 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, hand into a group but not dripping.
Feeding method of recycled feed and suitable proportion of feed
Although fermented chicken manure litter (ie, regenerated feed) has the acid and aroma of livestock and poultry taste, it can stimulate the secretion of digestive juice of livestock and poultry, and improve the digestibility and palatability. However, any feed for livestock and poultry has an adaptation process. Must pay attention to the basis of the original feeding, from less to more, so that the pig gradually adapt. 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%, the proportion of suitable sows and pregnant sows is 80%-90%, and the appropriate proportion of prenatal and lactating sows is 40%-50%. Feeding, red pigskin pigskin, fast growth, strong resistance to disease. The sows have normal estrus and high litter size. The piglets are well-balanced and robust and do not dilute.
