1. Ground culture: Ground culture is the most commonly used method at present. Keeping the temperature of chicks growing and developing can be informal. But the way of litter varies. One is to loosen the litter, remove the chicken droppings, dry it before use, and replace the bedding if necessary; the other is not to remove the feces, nor change the litter, but according to the degree of contamination of the litter, Thicken and clear out when the chicks are sold. The latter is also called thick mat grass raising method. This method can save labor, and the heat generated by the fermentation of beryllium can increase the room temperature. In addition, vitamin B12 can be produced due to the action of microorganisms. Plane feeding methods can be used artificially for feeding water and feeding, and semi-mechanization can also be used. The advantages of flat feeding are less investment, simple equipment and less defective products. The disadvantage is that it has a lot of floor space, requires a lot of litter, and easily spreads the disease through feces.
2. On-line flat-raising: Online flat-raising is the cultivation of chickens on specially made net beds, net beds, bed frames, bottom nets and fences. Can be drawn on the spot, wood, bamboo, iron can be used. The size of the mesh is such that chicken feet do not enter and chicken droppings can be dropped. If a metal mesh bed is used, it can be made of 12-14 galvanized iron wire. The mesh size is 1.25x1.25 cm. The bottom net is 50 to 60 centimeters from the ground. The size of the net bed can be arranged according to the size of the house, but enough walkways should be left for operation. Adopting online raising, the number of chickens accommodated per square meter is 0.5 times more than that on the ground. It is easy to administer on the Internet, with low labor intensity and less contact between chickens and chicken droppings, which can greatly reduce the incidence of white feather disease and coccidiosis. In order to reduce the incidence of breast broilers in broilers, an additional layer of elastic square mesh or nylon net can be applied directly to the web.
3. Cage culture: It is actually a three-dimensional chicken. From the shell to the sale are kept in the cage. With age and weight gain, generally can adopt the method of transfer layer and cage. Although there are many advantages in raising broiler chicken cages, such as facilitating mechanization and self-management, the utilization rate of chicken houses, fuel, litter and labor can all be saved, and it can also effectively control the spread of coccidiosis and other diseases, but the cage Broiler chickens are not very common. The main reason is that due to the large initial investment, especially the incidence of breast cysts is high. If they are reared improperly, there will be more sternum flexion and soft leg disease, and therefore can not universal. However, from the perspective of future development, it is promising to raise chickens in cages. As long as the cage material structure is improved. Not to mention the fact that the flesh has produced a flexible plastic cage bottom, which will greatly reduce the incidence of breast cysts in broilers, and will allow cage-breeding chickens to develop better.
Hearing aid manufacturers strive to optimize their wireless hearing aid offerings both in terms of connection reliability as well as power efficiency. Variance across patients and listening conditions can make optimizing wireless hearing aid systems a complex process.
Factors such as connection distance, proximity of reflective surfaces, interference from other wireless devices, and energy loss through body absorption must all be factored into the hearing aid design. For example, indoor wireless performance may be very different from wireless performance experienced outdoors, where the only reflective surface may be the ground on which the hearing aid user is standing. Furthermore, individual differences in body geometry increase the variability that wireless engineers must account for when designing a system that provides each user with a consistent and reliable experience.
As awareness of wireless hearing technology grows, hearing healthcare professionals may notice an uptick in long-term safety concerns. Consumers should be confident knowing that wireless hearing aids are safe and strictly regulated medical devices that meet governmental wireless communication standards in addition to those set forth for medical devices.
