Green feed Green fodder includes banana stalks, grass rafts, various leafy vegetables, pastures, and the like. Green fodder is a commonly used vitamin supplement feed. If the pig diet lacks green fodder, the digestibility of the feed is low and the pigs grow very slowly. Green feed contains more inorganic salts, and the ratio of calcium, phosphorus and potassium is appropriate. There is enough green fodder in the diet, and pigs rarely suffer from diseases caused by the lack of inorganic salts. When feeding green pigs, pay attention to the following: If the green feed is not polluted, it is best not to wash it. Because of the fresh green feed, the more clean the water, the more water-soluble vitamins are lost. Boiled green feed is even worse. Because of the high temperature, most of the vitamins and proteins are destroyed. After heating, the formation of nitrite is accelerated, and pigs are easily poisoned after eating. Green feed is currently in use and should not be stacked. The green fodder is fresh and delicious, and the pig loves to eat. If it is piled up for too long, it is easy to heat and turn yellow. It not only destroys some vitamins, but also reduces palatability, and it also produces nitrite and causes pig poisoning. The amount of feed is moderate, calculated as dry matter, accounting for 20% to 25% of the diet, calculated as fresh, about 75%. Leaf type The commonly used leaf feeds for pigs include pine needle powder, eucalyptus powder, and amorpha powder. Inorganic salt feed Calcium and phosphorus are inorganic salt feeds that must be supplemented in large quantities. Lack of calcium and phosphorus reduces the appetite of the pigs, poor growth, and softening of the bones. In inorganic salt feed, pigs also need salt, which can be supplemented according to the feeding standards of various types of pigs. However, it is necessary to consider the salt content in fish meal and sauce residue to prevent salt poisoning. Silage Silage has many advantages, such as better preservation of nutrients; can be eaten all, reduce waste; with sweet and sour taste, good palatability, pigs love to eat; stimulate the secretion of digestive juice, enhance gastrointestinal motility, help digestion absorb. Silage method: In the season of green feed, a part of silage is used to solve the shortage of off-season green feed. After harvesting, the green fodder is sun-dried with 30% water and cut into 10 cm to 13 cm long. In the cement pool or in the pit, spread a layer of about 20 cm, sprinkle some salt, tighten with the feet, and laminate the layers tightly. Cover the plastic film, do not leak, and use a thin paste to feed the pig for half a month. When using the material, pay attention to take it from one side, take the back cover and prevent it from rot. Roots, tubers, melons and fruits Such as sweet potato, potato, cassava, pumpkin, beet, watermelon rind, zucchini, etc., they are characterized by high moisture content, good taste, and pigs love to eat. The disadvantage is that the protein content is low. Sweet potato (sweet potato) has a higher nutritional value. It is better to cook it. The sweet potato with black spot disease will poison the pig and cannot be used as feed. The potato is cooked well. The mature and germinated potato contains a toxic substance called solanine. It is easy to cause gastroenteritis when it is eaten. This substance is the most abundant in the green skin and bud. Before taking care, cooking can also reduce its toxicity, but the remaining water can not be fed to pigs. Cassava contains hydrocyanic acid, which can poison pigs. It can be attenuated by soaking, boiling, drying or heating to 70 °C ~ 80 °C. Green hay Green hay is made from fresh wild pasture or cultivated grass. The quality of the hay is green, fragrant, rich in protein, inorganic salts and carotene, good palatability and easy to digest. The nutritional value of hay is closely related to harvesting, modulation and storage methods. Leguminous forages start from flowering to full bloom, and grasses from heading to flowering are suitable harvesting periods. The grass is flattened before drying, and it is easy to dry. The hay made is bright green and tastes good.
Spade bits are used for rough boring in wood. They tend to cause splintering when they emerge from the workpiece. Woodworkers avoid splintering by finishing the hole from the opposite side of the work. Spade bits are flat, with a centering point and two cutters. The cutters are often equipped with spurs in an attempt to ensure a cleaner hole. With their small shank diameters relative to their boring diameters, spade bit shanks often have flats forged or ground into them to prevent slipping in drill chucks.

Some bits are equipped with long shanks and have a small hole drilled through the flat part, allowing them to be used much like a bell-hanger bit. Intended for high speed use, they are used with electric hand drills. Spade bits are also sometimes referred to as "paddle bits".
Spade drill bits are ordinarily available in diameters from 6 to 36 mm, or ¼ to 1½ inches.
