Feeding fattening ducks in autumn ducks means that ducks can quickly gain weight and fatten in a short period of time by means of oversupply of heat and protein. When the duck grows to 50-60 days old and weighs about 1.5 kg, it can start feeding. Normally, it takes 12 to 14 days in the fall to increase body weight to more than 2.5 kg in the short term. The feed is mainly fed with bran in the early stage of the feed, with a small amount of corn flour, flour, sorghum flour and other starch feeds, and with appropriate amounts of beans and bean cake, the crude protein level is kept at about 15%. Gradually reduce bran feed and increase starch feed. In the last week, starchy feeds were mainly used to reduce beans and feed bran to increase the fatness of ducks and ensure fresh quality. Duck late formula can be used corn or rice 55%, wheat flour 25%, 10% of corn flour, soybean meal 6.6%, bone meal 3%, salt 0.44%. Feeding methods Family feeding uses hand-feeding. Mix the mixture with water first, make it soft and hard, then grow 4-6 cm by hand, 1.5-2 cm thick, and "filled bars" with blunt ends. When filling, the operator sits on a bench, 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 cavity with the right hand after filling with water and enters the esophagus. Fill it out. Fill 3 times a day, fill in 3 to 5 pieces at a time in the initial stage, and then gradually increase. If there is no phenomenon of indigestion, it can be increased to 8 to 10 pieces at a later stage and 0.4 to 0.5 kilograms of mixed concentrates can be fed on a daily basis. Precautions Feeding should be timed. Fill in three times a day and night, every 8 hours. Before each filling, check the digestive conditions. If there is still food in the neck, pause filling or less filling, and add 0.3% baking soda to the drinking water. After feeding, provide sufficient clean drinking water in time. Appropriate release of water and exercise; to keep the duck house clean, quiet environment, dim light, not harsh drive away and loud noise; pay attention to heatstroke cooling, keep good ventilation, cool and comfortable; playground should be scaffolding or planting trees.
