Scientific rearing duck technology
1, control the temperature. Breeding ducks need suitable temperature is 15-18 degrees Celsius, less than 5 degrees Celsius or higher than 35 degrees Celsius ducks will produce a stress response, affecting the production of eggs. Therefore, in the wind, snow, cold, cold winter and early spring, do duck house clean, dry and warm, ventilated sunny, cold and moisture. In summer and autumn, the season of high temperature is achieved: cooling by heatstroke, cooling and ventilation, moisture-proof and dehumidification, air circulation, and regular disinfection to keep duck houses cool in winter and cool in summer. In order to adapt to the habits of breeding ducks. 2, reasonable lighting. The lighting of the duck should be fully reasonable. It is necessary to keep the day and night light for 20 hours, of which the strong light is the best for 16 hours. It is necessary to artificially supplement the light in the morning and evening. 3--5 hours, gradually increase to the morning and evening after the "winter solstice". A 40-square-meter kindred duck house with three 15-watt electric lighting fixtures can satisfy the lack of illumination. If there is a power outage, the lighting must be supplemented with a power-off treasure, standby power supply, or candles. The lighting must not be affected by the blackout. Otherwise, After the drop in egg production rate, it will not be able to pick up. 3, feeding ingredients. Breeding ducks need to provide nutrient requirements according to the breeding standards of ducks, and scientifically formulate feeds to reduce waste. The special roller feed nutrient requirements during the laying period of ducks are high quality and stable. It requires the feed to contain 18%-20% of crude protein, 3%-3.5% of calcium, and 0.4%-0.5% of phosphorus. Ducks do not easily change any nutrient indicators during their egg production, and they can't change the feed at will. Otherwise, the egg production rate will drop drastically. At the same time, we must add nutrient-rich, fresh and fresh green materials, such as fine green ash, water lotus, water peanuts, cabbage leaves, vitamin deficiencies. 4, to prevent surprise. Ducks are most afraid of convulsions and stress, especially difficult to recover in the short term after a frightened group, because ducks mostly lay eggs at midnight from 1 to 4 o'clock, and fewer ducks lay eggs after laying ducks. Ducks with high egg production rate have stagnation When the egg rate is low, the female duck is most afraid of being frightened when it lays eggs. When it is frightened, the ducks become chaos, squeal each other, collide and hit and affect the production. As a result, soft shell eggs are increased, shell eggs are increased, and the egg production rate is decreased. Therefore, it is necessary to keep the ducklings in a quiet environment, keep the ducks quiet, prevent strangers and non-feeders from entering the duck shed, and prevent dogs, rats, snakes, and wild animals from disturbing the ducks. The egg-laying duck sheds use only 2 to 15 watts. Electric lighting. At the time of grazing, the ducks are allowed to walk freely. They can't chase after the rush. In case of thunderstorms, heavy rain, and windy weather, the ducks must be sent back to the ducks in advance to prevent the occurrence of panic and stress. 5, keep dry. Although a duck is a water bird, it loves to be dry and clean. It often cleans feathers after it is full, keeps feathers clean, and looks for mating in the water. Therefore, it is necessary to supply clean, fresh and slow running water to allow the duck to drink freely. Keep dry, clean, and hygienic in the kind of duck house and rest place, use grain sugar and mixed wood ash or cinder gray washers, prevent moisture and dehumidify, disinfect and sterilize, and stack a layer of dry straw or straw on the walls around the duck house. , With cold and dehumidification, anti-heating cooling effect. 6, a reasonable group. Breeding breeding ducks should not be too large, the group should be scientific and reasonable, each group of ducks is generally suitable for 200--250 feathers, more than 500 feathers must be reared in groups, every 16 female ducks breed 16-20 pigeons The breeding density is 6--8 feathers per square meter, but it is necessary to make adjustments according to the changes of the season. The winter and spring densities should be greater, and the density in summer and autumn should be smaller, which is beneficial to the robust growth of ducks. 7, do egg nest production. It is best for the female duck to lay eggs, and the female duck prefers to lay eggs in the nest. With the soft and suitable dry straw or dry grass made egg nests, ducks will enter the nest eggs, do not use artificial training, the mother ducks generally become habits in the nest eggs for 3 - 5 days, and fixed in their own Eggs are laid in nests. The nests are located in hidden areas near the wall. When the ducks lay eggs and leave the nests, the eggs will be carried away immediately. If they are not picked up in time, the mother ducks will have a love nest and affect the production of eggs. It will also increase the number of damaged eggs. Hatching hatching rate and economic benefits. 8. Disease prevention and control. The epidemic diseases of ducks are more and more complex. We must follow the principle of "prevention first, prevention and control combined with prevention and prevention of treatment," and strengthen scientific feeding and management to remove the excrement in time. Each year inoculated duck plague 1 times, poultry defeated 2 times, and usually also use oxytetracycline, compound diarrhea net and other drugs mixed feed, strict control of duck ducks viral and bacterial infectious diseases.
