More than 70% of the ammonia in chicken diets is excreted in the feces, so chicken manure has a large feed value. However, its palatability is poor, and it contains a large number of pathogenic bacteria. If it is directly fed, it will not only reduce the utilization rate of chicken manure, but also lead to adverse consequences. The author uses a multi-enzyme saccharification bacteria to produce chicken manure feed by two-stage fermentation method, which not only saves grain, but also has significant disease prevention effect. The brief introduction is as follows:
After removing the chicken manure, inoculate 0.5% of the activity according to 35% chicken manure, 40% grass straw powder (or tapioca flour, rice bran, etc.), 15% bran, 10% cornmeal, 2% salt. The preparation solution of the multi-enzyme saccharification bacteria is well mixed, so that the moisture content of the mixture is about 65%. The water is not seen in the finger gap, and the hand is loosely dispersed, loosely stacked on the cement floor, with sacks or plastic. The film covers the material temperature. At 28 ° C - 37 ° C; conditions; aerobic fermentation 12 hours after the stacking, and then aerobic fermentation for 24 hours. The aerobic fermentation raw material is put into the layer of the brick cement pool prepared in advance, and the two layers of the sand are sealed on the film to make it absolutely sealed (no air leakage, water immersion). After 10 days to 15 days of anaerobic fermentation, the chicken manure is converted into a nutrient-rich biological feed. The color of the feed is golden yellow and has the aroma of apple cider, wherein the crude protein content is 15%, the crude fat content is 1.8%, the nitrogen-free extract is 15%, the crude fiber is 14.9%, the calcium is 7.4%, and the phosphorus is 2.1%, which is not only good palatability. Moreover, it is rich in nutrients, and livestock, poultry and fish all like food, and can also improve the disease resistance of livestock and poultry. The chicken manure feed made by the two-stage fermentation method can be dried or dried naturally, and stored or made into pellet feed.
When feeding livestock, poultry and fish with chicken manure feed, you should pay attention to:
1 Chicken manure feed has a higher nutritional value, but it is not a full-price feed and should not be fed separately. According to the nutrient composition of chicken manure feed, it should be properly formulated into full-price feed with other feeds when feeding;
2 Chicken manure feed has a high non-protein nitrogen content, so the feed utilization rate is higher when feeding ruminants such as cattle and sheep.
3 When feeding livestock, poultry and fish with chicken manure feed, it is better to add antibiotic additives such as oxytetracycline and feeding additives such as salt, baking soda and plaster.
General Introduction
Bit Face Shape Selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The all-around application bit face specifically for medium hard and homogeneous rock formations.
Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce theload and wear on the gauge buttons, but poor hole deviation control.
4. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
Carbide Button Shape Selection:
1. Semi-Ballistic Buttons
2. Ballistic Button
3. Spherical Button
4. Two-step Button
Raw Material
Steel:
First class special alloy steel with high strength, heat resistance and wearable
Carbide
The best tungsten carbides from China are commonly applied.
Tungsten carbide from European is also available.
