1. We must purchase high-quality full-price feed In the areas where meat duck production is concentrated, most of the duck farmers use the full-price pellet feed from famous brand manufacturers. However, there are also some duck farmers who are unwilling to purchase cheap, non-trademarked, non-approved documents, and feeds without inspection certificates at small feed processing plants or consignments. Because the quality of feed is not guaranteed, it will affect the growth and development of ducks and the economic benefits of ducks. For this reason, the author suggests that the duck farmers must buy the feed produced by the regular feed mills.
2. Be sure to buy high quality premixes. Some duck farmers have to buy soy bran, corn, bran and other ingredients to reduce feed costs. Then buy the premix and self-modulate the duck full price material. This method is okay, but it needs to remind the duck farmer that the premix is ​​nutritious and the structure is very complicated. There is no small-scale feed with certain technical expertise. It is difficult for a production unit to develop a high-standard, high-quality feed formulation. Therefore, the use of such pre-mixed feeds is difficult to achieve nutrient "full price", which will inevitably affect the growth and development of ducks and the economic benefits of duck farmers. Therefore, the duck farmers themselves must purchase the premix to select the manufacturers, select the brands, and pay attention to quality.
3, we must ensure that the feed nutrition comprehensive whether it is to buy feed or its own modulation feed must ensure that the nutritional composition of a comprehensive, in line with the growth and development needs of ducks, which is doing a good job of large-scale duck production, improve the key to economic efficiency. Because there are dozens of nutrients in the meat duck feed, it is difficult for the duck farmer to determine whether the nutrients in the feed are comprehensive. Duck farmers must pay attention to whether there is a feed product label when buying feed, and see if the above-mentioned nutritional standards meet the national standards.
On this basis, if the duck farmer wants to know more accurately whether the nutrient content in the feed has reached the meat duck requirement, he can ask the professional department to inspect it.
4, must buy high-quality feed raw materials If the duck farmers to prepare their own feed duck full-priced feed, it is necessary to buy feed ingredients according to local conditions, do not buy moldy raw materials, raw materials, impurities, water must be in the provisions Within range. The proportion of various feed ingredients should be reasonable.
5, we must pay attention to feed feeding methods according to different age and growth of ducks need to use different nutrient standard feed. Ducklings should be used during brooding. During the growth period, ducks or ducks should be used according to actual conditions. In addition, we must pay attention to the method of feeding feeds, and some ducks and adolescents can save time by adding too much feed to the feeding containers. One day or even several days, the ducks cannot eat the feed. The correct method should be based on the feeding situation of ducks less feeding Tim, it is best to regularly add feed. This will not only maintain the good appetite of the duck, but also save feed and facilitate the management of ducks. The basic requirement for regular feeding of feed for ducks is to feed the feed once every 3-4 hours during the brooding period, and gradually increase the interval between feeds as the age of the duck increases, and increase the amount of feed each time. Ducks are 25-30 days old and feed once every 6-8 hours. Feeding time is best arranged during the day to facilitate the nighttime rest of ducks, reduce physical exertion, and promote growth and development.

Material: It is made of HSSM35 material imported from Japan, high temperature quenching, hardness reaches HRC64-65, ultra-high temperature quenching, high hardness, copper key and iron key are available, good wear resistance
Production process: Using full CNC grinding machine, full grinding technology, with sharper tip and easier to cut the key. The cut key is smooth and burr-free;
Suit for machine: It is suitable for all kinds of single-head and double-head key machines. It can be used by any quality machine. It does not need to change the machine and also can process copper keys and iron keys on same key machine. No longer needs to change the cutter.
Before running the machine, it is necessary to accurately adjust the cutter to ensure the key blank and the parent key are matching, and to avoid the tool being broken due to the unstable key assembly.
The cutter is clamped on the machine and the key blank and the parent key are fixed on the clamps. Do not clamp the key blank too tight. The patent key is close to the tracer and the key blank is close to the cutter. If the key blank is not fastened, the key blank should be removed and reclamped.
When the machine is not running, clamp the cutter and cut from the left-to-right to check if the position of the parent key and the key blank are uniform. If not, re-clamp again.
