The suitable climate in autumn is the best season for feeding and fattening ducks. It is possible to quickly increase the weight of fattening ducks in the short term by artificially oversupplying heat and protein feeds. Fill fat ducks have good economic benefits because they have good subcutaneous fat deposition, well-balanced body shape, and fresh meat. They are most suitable for roast ducks, ducks, and ducks. 1, feeding time. When the duck grows to 50-60 days old and weighs about 1.5 kg, it can begin feeding. At this time, the filling weight gains quickly and the feed reward is high. Normally, it takes 12-14 days to feed the duck in the fall, which can increase the body weight of the duck to more than 2.5 kg. 2, fill feed. The quality and quantity of fillers have a great influence on the effect of fertilization. Feeding ducks should be dominated by high-energy, easily-digestible starch feeds and must maintain a certain protein level. The pre-feed is mainly bran-based, with a small amount of corn meal, flour, sorghum flour and Other starch feeds, and with an appropriate amount of protein feed such as beans and bean cake, the crude protein level is maintained at 15% or more. Gradually reduce bran feed and increase starch feed. In the last week, starch-based feeds were mainly used to reduce the feeds of beans and not feed bran to increase the fatness of the ducks and evenly distribute the deposited fats between the subcutaneous and muscle fibers to ensure their fresh quality. After the duck feed formula: corn or rice powder 55%, wheat flour 25%, corn flour 10%, bean cake powder 6.6%, bone meal 3%, salt 0.4%. 3, feeding method. Most families use it for hand-feeding. Mix the mixture with water and mix it to make it soft and hard. Then grow 4-6 cm thick and 1.5-2 cm thick blunt end “filling stripsâ€, each kilogram of material. About 60 pieces are produced. When filling, the operator sits on a small stool, fixes the duck between his legs, opens the duck's beak with his left thumb and forefinger, presses the duck's tongue with his middle finger, and fills the top of the chamber with the right hand and enters the cavity into the esophagus. Fill it out. Fill 3 times a day, fill 3-5 pieces each time in the initial stage, and then gradually increase. If there is no indigestion phenomenon, it can be increased to 8-10 pieces each time in the later period, and 0.4-0.5 kilograms of the mixture can be fed on a daily basis. After skilled in operation, 50-80 ducks can be fed per hour per person. 4, attention. During the feeding of fattening ducks, the meat ducks must digest the feed they feed in, quickly grow their flesh, deposit fats, and have a very special physiological function. It is extremely important to strengthen management. Special attention should be paid to the following issues: First, fill in the food regularly, fill it up three times a day and night and fill it every 8 hours. Before each filling, check the digestive condition. After about 7 hours of feeding, the feed is basically digested. If there is still food in the touched neck, indicating indigestion, it should be suspended or underfilled and 0.3% added to the drinking water. Baking soda; Second, timely feeding of clean drinking water should be provided in time for appropriate digestion and exercise to help digestion, enhance physical fitness, and prevent the appearance of stumpy ducks; third is to keep the duck house clean and hygienic, so that the environment is quiet and the light is dim. They must not be ruthlessly chased and loudly quarreled; the fourth is to maintain good ventilation, cool and comfortable, and promote fat deposition. China Agricultural Network Editor
