Duck Filling and Fattening Technology in Autumn and Winter Season

Ducks in autumn and winter are fed with fattening, which means that ducks can quickly gain weight and fatten in a short period of time by means of excessive supply of heat and protein.

Feeding can be started when the duck reaches 50-60 days of age and weighs about 1.5 kg. Generally, it takes 12-14 days to fill in the autumn, which can increase body weight to more than 2.5 kg in the short term.

First, fill feed. The pre-feed was mainly bran-based, with a small amount of corn meal, flour, sorghum flour, and other starch feeds. With the appropriate amount of beans and bean cakes, the crude protein level was kept at about 15%. Gradually reduce bran feed and increase starch feed. In the last week, starch-based 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%, 25% wheat flour, 10% of corn flour, soybean meal 6.6%, bone meal 3%, salt 0.4%.

Second, feeding method. Family feeding is more manual feeding. First mix the mixture with water and make it soft and hard. Then grow 4-6 cm by hand, 1.5-2 cm thick, and fill the strips with rounded ends. When filling, the operator sits on a stool and fixes the duck between his legs. He uses his left thumb and forefinger to open the duck's beak. The middle finger presses on the duck's tongue. The right hand will fill the cavity after filling with water and top into the esophagus. Fill it out. Fill 3 times a day, fill 3-5 pieces at a time in the initial stage, and gradually increase afterwards. If there is no indigestion phenomenon, it can be increased to 8-10 pieces at a later stage and 0.4-0.5 kilograms of mixed concentrates can be fed on a daily basis.

Third, pay attention to matters. Filling should be scheduled. Fill in three times a day and night, every 8 hours. Before each fill, check the digestive conditions. If there is still food in the neck, pause filling or less feeding, and add 0.3% baking soda to the drinking water. After feeding, provide enough clean drinking water. Drain and exercise properly; keep the duck house clean and hygienic, make the environment quiet, the light is dim, do not drive out harshly and loud noises; pay attention to the cooling of the heatstroke, keep the ventilation in the house good, cool and comfortable; the playground should be scaffolding or planting trees .
