Autumn duck filling method

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: the duck grows to 50-60 days of age, weight about 1.5 kilograms can begin to feed, when filling fertilizer weight gain fast, high feed remuneration, but also less prone to duck fat phenomenon. 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 the filler have a great influence on the effect of the fill fertilizer. The feed duck should be dominated by high energy and easily digestible starch feed, and it must also 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: family used for hand-feeding, first mix and add water and mix well, make it soft and moderate, then grow 4-6 cm by hand, thick 1.5-2 cm at both ends of the obtuse Article "about 60 pieces of material per kilogram. 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. Note: During the feeding of fattening ducks, the meat ducks must digest the feeds they fill in, quickly grow meat, 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.
