First, free to feed fattening. During the fattening period, high-energy, low-protein compound feeds should be used. After feeding, ducks should be put into the water for bathing and water plants should be taken in order to facilitate digestion. One night food should be fed while feeding. Management attention should be paid to the darkness of duck housing, so that the ducks are less active and have more rest. Guan Ya site should be clean, avoid moisture, odor, or seriously affect the fattening effect. Reference feed formula: corn 40%, sorghum 15%, wheat bran 10%, wheat 23%, bean cake 7%, salt 0.5%, shell powder 2%, bone meal 2%, trace element additive 0.5%, poultry multivitamin 5 grams.
Second, artificial feeding fattening. Reference feed formulation: corn 45%, wheat 15%, wheat bran 10%, barley 25%, bean cake 5%, bone meal 1.5%, shell powder 2%, salt 0.5%, trace element additive 0.5%, poultry multivitamin 5 grams. Put 2/3 of the well-mixed mixture into the pot, add the same amount of boiled water, scald, stir into a paste, then add another 1/3 of the dry material. After fully stirring, the wolfberry grows 5-6 cm and weighs about 25 grams. Left and right sticks. When licking the emboli, keep your hands wet and keep the surface of the embolus smooth for filling. Winter can be done once every 2 days. To prevent the emboli from cracking, cover it with a damp cloth.
The specific operation method for artificially feeding ducks is as follows: A duckling sits on a low stool, spreads the wings of the duck, clamps it in the curve of the left leg, holds the duck's upper jaw with his left thumb and forefinger, and presses the front of the duck tongue with his middle finger. Use your right hand to hold the wet embolus, massage it down the esophagus and send the embolus down. Fill 3-4 plugs every day initially and gradually increase to 13-14 plugs. In order to make the ducks become accustomed to filling, the first 2-3 days of feeding and filling. Before each filling, check the digestive status of the ducks. If you find that the digestion is not good, you can fill it in less to prevent food accumulation. Weak ducks do not use manual feeding for fattening.
The management of artificially fed fattened ducks is mainly to keep quiet around the ducklings. Circle temperature is maintained at 15 °C -24 °C, winter is not less than 5 °C, avoid ring temperature is too high, so as not to affect the fattening effect. Feeding ducks has a large amount of food and needs a lot of drinking water to digest well. Therefore, a basin should be set up inside the circle so that the ducks can freely drink water. In addition, every day, it is necessary to go swimming for 2-3 times, each time for 10-20 minutes.
Food additives are compounds or natural substances added to food for the purpose of improving the color, aroma, and taste of food, as well as for the needs of anti-corrosion and processing technology. At present, there are 23 categories of food additives, with more than 2,000 varieties, including acidity regulators, anticaking agents, defoamers, antioxidants, bleaching agents, leavening agents, coloring agents, color retention agents, enzyme preparations, and flavor enhancers, nutritional fortifiers, preservatives, Sweeteners, thickeners, spices, etc.
