Winter feeding tube technology for ducks
After the ducks have stopped production in winter, in order not to affect the laying rate of the leap year, feeding and a small amount of supplements should be appropriately limited, that is, the supply of ducks can ensure the nutrition needed to maintain life activities, and ducks cannot be overgrown. Ducks have a strong ability to keep up with the cold. In addition to snow and snow, ducks should be driven out of grazing. This stage of grazing usually starts at 8 to 9 am, and the ducks are driven back to the duck house before the sun goes down. When grazing, let the ducks move forward in the wind to prevent feathers from being caught in the wind and catching cold. When the ducks are together, they must work diligently to increase the activities of the ducks and promote appetite. When feeding, you can make food supplements according to your eating habits, but you should not feed them too well or too much. When grazing, you should drive several times a day in the duck house to increase activities. Before the Spring Festival, feeds should be gradually added and the number of feedings should be increased to promote the early opening of ducks. The winter in the north of the country is cold and cold. When feed in the pasture is reduced, it must be converted to captivity in time. There is a large temperature difference between day and night in winter. When breeding ducks, ducks should be prevented from catching cold. In order to maintain body heat, the ratio of energy feeds may be appropriately increased to increase egg production in conjunction with diets. At the same time, it is necessary to increase the level of nutrition in the diet and appropriately increase the content of soybean cake and fish meal. Conditions should be fed more green feed to ensure that the nutritional needs of duck breeding eggs, lack of green feed should be added industrial synthesis of multi-dimensional pigments. It should be noted that the need for inorganic salts is greater for laying ducks. Calcium is rapidly metabolized in ducks and stored in small amounts. It needs to be continuously extracted from the feed. Therefore, the calcium content of the small particles should be supplemented as much as possible in the compound feed, and it can be placed on the corner of the playing field or duck shed in the basin. The group eats freely. The commonly used calcium powders are stone powder and shell powder. In addition, trace elements in the feed for breeding ducks are also essential, especially manganese, which can increase the fertilization rate of the eggs. Egg-producing ducks were fed 4 times a day, 3 times during the day, and 1 at night. The amount of condiment feeding should be 200-250 grams per day so that each duck can eat well and play the biggest potential for egg production. The winter duck house must have heating equipment to increase the temperature. The suitable temperature for the housing is 10-20°C. Below 0°C, the egg production of breeders will drop significantly. Ducks must have rules of life during the laying of eggs and should not be changed at will, so as not to affect the formation of eggs and the fertilization rate. Illumination has a stimulating effect on the metabolism of ducks. Too much or too little light can lead to bad consequences. If the illumination time is too long and the light intensity is too strong, there will be problems of early maturation of the duck, premature egg weighting, lengthening of the time required to reach the standard egg, reduction of the qualified rate of the breeding eggs, and low fertilization rate. Reserve ducks before 4 weeks of age, light for 23 hours a day, 8 to 20 weeks of age, if only in the open ducks to natural light, low light at night lighting, 21 to 26 weeks of age gradually increase the light in the morning and evening, The natural light and artificial light can reach 17 hours per day, and the light time is fixed after 26 weeks of age. In the breeding process, we must master the ratio of breeding male and female ducks, the proportion of meat-type males and females is 1:5 to 8; the proportion of males and females that use dual-use ducks is 1:10 to 15; The duck ratio is 1:15-20. If there are too many ducks, feed will be wasted and the female ducks will be rested and eaten. If there are too few male ducks, the fertilization rate of the eggs will be reduced. Set egg nests as early as possible before laying eggs, which are often set at 24 weeks of age. The size of the nests is 35 to 45 centimeters (35 to 45 centimeters) (35 to 45 centimeters). , The bottom of the hollow put soft litter, every 4 mothers set up a nest box. When it is first produced, it is best to place a "picker" in the nest. The nest box should be located on the side where the duck is resting, away from the waterer and the feed bowl. Ducks are very sensitive to environmental changes, and they are susceptible to crowding, refusal, and screaming after being frightened, resulting in reduced egg production or production of soft shell eggs. In the event of a frightened group, keepers should immediately call the ducks to calm the ducks as soon as possible. Although the duck is a water bird, the duck house should be kept clean and dry throughout the year. In winter, under the premise of insulation, ventilation and ventilation should be taken to prevent excessive harmful gases and affect the health of ducks. Duck disease is an important factor influencing the egg production of female ducks. Therefore, prevention work should be done and injections such as duck plague and duck cholera should be prepared according to immunization procedures. Grazing ducks are susceptible to parasitic diseases, so they are regularly dewormed. For the long-term high-yielding duck populations, special attention should be paid to the occurrence of fowl cholera.
