Eight Principles of Winter Duck Farming in Rural Areas
Eight Principles of Winter Duck Farming in Rural Areas
(A) adjust the duck group. Before the arrival of winter, ducks should be adjusted to eliminate the old, weak, sick, ducks, low-yielding ducks and discontinued ducks in time, leaving ducks with good production performance, strong physique, and normal egg production. Specific methods: A look: The main wing feathers fall off or the body plume falls off, the base of the cockroach turns yellow, the body is weak, or the feathers are good but the individual is very fat. Second touch: cloacal small and dry, abdominal volume is small, hard, pubic bone spacing, no eggs in the birth canal. The duck with the above characteristics is a productive duck or a low-producing duck.
(B) cold and warm. The suitable temperature for duck egg production is 13-20°C. If the temperature is too low or too high, egg production will decline. Therefore, maintaining the relative stability of the ambient temperature is the key to high and stable production of winter ducks. The main measures for keeping warm and cold are: (1) Close the doors and windows, hang the straw curtain, and guard against the thieves. (2) Spread straw or straw about 30 cm thick. (3) Increase the breeding density appropriately, 8-9 eggs per square meter, and use the body temperature of ducks to increase the temperature. (4) It should be properly warmed up at night when the cold arrives. (5) ventilation. If over-emphasis is placed on heat preservation, poor indoor ventilation and increased ammonia concentration can easily induce various diseases. Therefore, when the duck is released, doors and windows should be opened to increase ventilation and ventilation, and close the doors and windows immediately after returning.
(c) Change diets. Winter ducks need more calories to keep warm. Feed formulas should increase the proportion of corn, wheat, and other energy feeds, and add 1% to 2% of animal fats, so that the metabolic energy in feed can reach 12 kg/kg. - 12.5 MJ to meet the needs of the ducks for energy. The proportion of protein remains at 15%. Feed more green feed, supplement the fish liver oil regularly (refill it once every 8-10 days), and increase the feed intake of the duck (about 10%); due to the long night in winter, it should be properly fed at night to maintain High and stable production.
(d) Supplemental lighting. Light can stimulate the secretion of the pituitary and endocrine glands of ducks and promote the production of eggs in ducks. In winter, the time of natural light is short. To maintain high and stable production, light must be supplemented. In general, a 40-watt light bulb is hung for every 30 square meters, 2 meters away from the ground, and a lampshade is added. The time to light up the lights is generally 5-8 hours every night and 4-7 hours the following morning to ensure that the light hours are not less than 16 hours.
(e) induced estrus. Generally, 2% to 5% of the ducks are reserved in the duck population; the role of the male duck in sexual attraction and sexual stimulation on the female duck can promote the secretion and sexual reflex of the duck, and increase the egg production.
(f) Forced moulting. In the late autumn and early winter, the egg production of ducks gradually decreased and the shells became thin. At this time, artificial forced moulting could be adopted to enable the ducks to rapidly restore their production. Specific approach: separate the ducks to be moulted, stop the grazing, do not fill the light, unplug the wings of the ducks and the tail of the big hair, control the amount of feed - half the feed two days before, only two days after the water, do not feed After the feathers of the back and the chest of the duck are successively shed, they are fed gradually, and an animal protein feed rich in sulfur amino acids is supplied to facilitate the long hair of the duck. In 7-8 days, new feathers will grow in the wings of the ducks and their tails. After 20-40 days of feathers, they will resume production.
(7) Careful management. In today's fierce market competition, management benefits, and only careful management can improve economic efficiency. (1) timely release of water. Before releasing the water, let the ducks run on the dry land for half an hour before letting them in the water. This will prevent the ducks from cramping due to the cool water after they get into the water. Generally, the water is released 1-2 times a day. It is warm and sunny for about 1 hour, and rainy days are half an hour. When the water is released, it should be delayed in the morning and closed early in the afternoon. The place must be selected for leewardness. (2) insist on feeding warm food, drink warm water. The temperature of feed and drinking water can be in the range of 30-40°C to reduce cold stimulation of ducks and loss of body heat. (3) Reduce stress. Ducks and ducks are very sensitive and prone to stress. They should keep the environment quiet, prevent abnormal sounds, and prevent harassment from others and other animals.
(h) Prevention of diseases. Although the ducks have strong resistance and disease resistance, due to the influence of external environmental factors, ducks are also susceptible to disease, so they should be actively prevented. (1) Doing a good job of health: Pay attention to environmental sanitation in peacetime, keep the duck house dry and clean, have no mildew in the grass, remove the excrement in time. (2) Regular disinfection: The duck house should be sterilized regularly and generally be disinfected 7 to 15 days. (3) Disease prevention and disease prevention: While paying attention to the hygiene of feed and drinking water, antibiotics should be added in the feed and drinking water in a timely manner in order to prevent diseases.
