Efficient breeding techniques for Mallards
Mallards are also known as cannabis ducks, red-legged ducks and big ducks. They are introduced from the United States and other places. Breeding mallards have the characteristics of investment, quick results, and high returns, and are a shortcut for farmers to raise their wealth. At present, the cost of commercial meat mallard duck breeding does not exceed 15 yuan each, and the market price is between 22-25 yuan, each of which can make a profit of about 10 yuan, and the economic benefits are very significant. Here's a high-tech feeding technique for mallards. Let's take a look. First, the selection of venues Wild duck farms should be surrounded by farms, not only to consider the living habits of wild ducks and environmental requirements, but also consider the power, drinking water sources, roads and health and other conditions such as epidemic prevention should be built duck farms, ducks Beach, water surface and other supporting facilities. Wild ducks are afraid of wetness. Therefore, duck farms should choose high-dry terrain. They should face the south and ventilate southwards. They should be ventilated and conducive to heat preservation. They should stay away from factories with relatively noisy noise, residential areas, and major arterial roads. The duck farm should not be built in places with poorly ventilated dampness and surrounding tall buildings. Second, the selection of good young ducklings, good or bad, directly affecting the effect of brooding. Ducklings have the same hatching time, normal development, bright hair color, great eyes, good abdominal contraction, and struggle in the hands. Weak young duck hair dry, nail umbilical, large abdomen umbilical, soft, weak, too much weight or too light. Third, when transporting young ducks safely, each basket should be loaded with 80 to 100 eggs. It should be filled with straw, and cartons can also be used to contain ducklings. Cold weather should be covered with a thin cloth or a thick cover. Find out how the ducklings play, and unplug them in time. Avoid sun and rain during transportation. Fourth, the young room disinfection brooding room should be thoroughly cleaned before entering the chicks, the use of formaldehyde and potassium permanganate fumigation, close the doors and windows after about 30 minutes to open doors and windows, ventilation. After the 0.2% potassium permanganate aqueous solution was used to clean and sterilize the brooding space and utensils, the clean water was used to clean the brooding areas and utensils, and then the ducklings were put into the brooding room. V. Feeding compounding materials When young ducklings start eating, they must add a small amount of fishmeal in the feeding and feed the compound feed after a few days. At the same time, appropriate amounts of green feed, small fish, fresh meat, quail, and other live animals should be added. After one month of feeding, the protein content of the feed should be reduced to 10%, and the proportion of fishmeal and soybean meal should be appropriately reduced to gradually increase the proportion of roughage to 20%. Feeding 100 grams of green leafy fodder such as cabbage leaves, alfalfa and grass every day promotes the growth of the skeleton of the wild duck and postpones development. After 2 months, it is necessary to reduce roughage, increase the protein feed to 18%, and continue to increase the green feed. Six, open food drinking water in the pan or the drain pad on the plastic sheeting, put a little ducklings mixed with a little water full price pellets, so that ducklings free to feed. The ducklings used 0.1% potassium permanganate water for the first time to eliminate meconium. Insufficient drinking water will affect the growth and development, must provide adequate clean drinking water, and add the right amount of glucose and vitamin C. Seven, tune the water to clear the weather, outdoor ambient temperature (about 20 °C), ducklings should be given early to release water, so that ducks adapt to the domesticated ecological environment since childhood, enhance physical fitness. In summer, water can be released at 1 week of age, and it can be postponed to 2-3 weeks of age in spring and autumn. The release of water was done after eating. The first time of water release is slightly shorter, generally 15-20 minutes, after which the frequency of water release and the time of water release are gradually increased. After the water is drained, let the ducklings dry feathers on the grass and then return to the duck house after a short break. 8. Incubation and Controlling Humidity The ducklings should be controlled at 26-31°C within 1 week of age. After 1 week, the temperature can be reduced by 1°C per day. After 15 days, they should be maintained at about 21°C. After 3 weeks, they can be kept at room temperature. Observe the performance of ducklings at any time and adjust the indoor temperature in time. Humidity for brooding is generally 70% for 1 week, 60%-66% for 2-3 weeks, and 55% for later. Nine, light suitable for 1-3 day brooding room should be day and night light. Adequate light can increase the viability of the ducklings, stimulate appetite, help digestion, and keep the house warm and dry. If the lighting time is not enough during the day, artificial light can be used. Ten, disease prevention and cure disease The duck house should be kept dry, warm, clean and hygienic. Pay attention to disinfection at ordinary times, regularly disinfect the duck house with fungicide and other disinfectants, once every 3 days in spring and summer, and once a week in autumn and winter, infectious disease occurs. Daily disinfection should be adhered to. The ducklings were vaccinated with a viral hepatitis vaccine at 1 day of age, immunized duck quail vaccine at 20 days of age, and avian cholera vaccine at 30 days of age. Commonly used heart and lotus, honeysuckle and other soup mixed feeding, can reduce the incidence of ducks. Prone to aspergillosis in the spring, each duckling can be given 3-5 mg of nystatin, and with 0.1% copper sulfate solution as drinking water, has a good effect.
