Young ducks in captivity

Young ducks are medium-sized ducks that are 30-70 days old. At this stage, the duck grows fastest, requires more nutrients, has improved foraging, digestion and adaptability to the external environment, and generally uses captive breeding. First, the grouping and density of captive ducks The size of captive ducks may vary, but the composition of each duck group should not be too large, and 300-500 should be appropriate. Grouping should be consistent in size, age, species, and gender. The rearing density varies with the age, season and temperature of the duck. Generally 4 to 10 weeks of age 20 to 12 per square meter, 11 to 20 weeks of age 12 to 8 per square meter. In winter, the temperature is low and the density is appropriate. In summer, the temperature is high and the density should be smaller. The density of fast growth is appropriately smaller, and the density of slow growth is appropriately larger. Second, the young ducks in captive ducks' captive feeds shall not supply any green feed. They shall all supply mixed feeds to meet the growing needs. Feed should be diversified as much as possible to maintain the balance of energy and protein, so that sulphur-containing amino acids, vitamins, and minerals are all available. In the diet, grain, bran, pancake feed and green feed can be gradually increased. Animal protein (such as fish meal, lotus root, lotus root) and so on. Can choose 4 powder 40%, corn 20%, 15% bran, shell powder 5%, 10% rapeseed cake, fish meal 10% of the feed formulation. In addition, sand grains with a diameter of 0.2-0.4 cm should be placed in the duck house to enhance digestion and reduce mental consumption. During the breeding period, young ducks do not need too much protein in their diets, and their calcium content must also be suitable. Because ducks and ducks have not yet established a perfect breeding standard, the necessary nutrients will be increased or decreased according to the specific conditions of growth and development during feeding. Such as egg-type varieties, the normal opening date is 130-150 days, the standard opening weight is 1400-1500 grams, if the weight exceeds 1500 grams is considered too large, should be slightly restricted feeding, appropriate feeding more green feed And roughage. For poorly growing and light-weight ducks, the amount of feed should be appropriately increased. The average daily feed should be about 150 grams per day, plus a small amount of fresh animal feed. Feed 3-4 times a day. The interval between feedings should be as equal as possible to avoid hunger and inequality during feeding. Third, the management of young ducks in captivity 1. The duck houses should be cleaned and regularly sterilized. The duck house should be cool in winter, cool in summer, well ventilated and kept clean and dry. Drinking utensils and drinking water should be cleaned once a day. The duck house is regularly sterilized. 2, appropriate to strengthen exercise, promote bone and muscle development, prevent excessive fat. Every day, the ducks are rushed to exercise in their homes, each time for 5-8 minutes, 2-3 times a day. Conditional can be used for short-term grazing. 3, more contact with the duck group, improve the guts of ducks, to prevent surprise group. The young ducks have a small gall bladder and are particularly sensitive to breeder nerves. They should use feeding, water feeding, grass exchange, etc. to have more contact with ducks, and have the consciousness to develop duck guts so as not to be disturbed by strangers or environmental changes. Group, causing serious losses. 4. Strengthen the prevention of infectious diseases. There are two major infectious diseases of young ducks; cholera and duck plague. The general immunization procedure is: 60-70 days old injection of avian cholera vaccine, 100 days before the next injection of avian cholera vaccine. 70-80 days old injection of duck plague vaccine. For ducks that have been raised for only 1 year, they should be injected once a year for two or more years. 5, low-lighting lighting, overnight lighting. Usually young ducks are not used for strong lighting. The standard daylight hours should be stabilized at 8-10 hours per day and should not be increased before the start of production. Generally, 1 盏 15 watt bulbs are installed for every 30 square meters. When a blackout occurs, candles or kerosene lamps (with hoods) should be lit immediately to avoid causing panic and death. 6. Establish a stable system of work and rest. The living environment of the captive ducks is more stable than that of the stocking ducks, and it is necessary to make a regular schedule according to the habits of the ducks. After the formation of the rest and maintenance system, it should be as stable as possible, and no special circumstances should be changed.
