Feeding and Management Techniques in Egg-duck Brooding Period
1. Feeding and Management Techniques for Ducks and Ducks during Brooding Period Duckling Brooders are raised from the hatching stage to the 28-day-old period. Ducklings at this stage are delicate and difficult to grow well. Therefore, the following aspects must be done. Pre-Nutrition Preparation 1. The duck house should be built on the terrain of Gaozao, where the leewards are sunny, and a sports paddling pool is built around it. Three days before raising, fill the ground in the duck house, plug the rat hole, fix the doors and windows, clean it and disinfect it with 20% lime. 2. Prepare and maintain brooding equipment and utensils, such as heating equipment, drinkers, feed troughs, duck baskets, etc., and disinfect with 2% caustic soda. 3. The access passages between the brooding room, playground, and reservoir should be leveled off and fill the pit. ? Choose a good variety for captive ducks, choose Shaoxing duck "red hair green wing tip" type. These ducks are mild in temperament, suitable for confinement, small in size, material-saving, early maturity, wide adaptability, and strong disease resistance. They produce 260 to 300 duck eggs each year and have an egg weight of about 60 grams. Into the good chicks, and identify the male and female? 1. Choose Jian Chuan: choose to hatch on time, the umbilical ring healed well, strong physique, lively and lively, eye drums God, no blood and fast, uniform ducklings. 2. Select the breeding of female ducklings: male and female identification, can use pinch anal method, this method will not damage the ducklings. The method is: Hold the duckling with your left hand, gently grip the duck neck with your thumb and forefinger, and then use your right thumb and index finger, gently squeeze the anus, rub it a little before and after. If a sesame-sized protrusion is a male duck, flat no projection is a female duckling. Scientific Feeding (1) Pay attention to water release 1. “Water release†is also called “test water†and “water pointâ€. Please note that you must eat before you start eating, otherwise it may cause death. The release time was before the second day of eating. ? 2. Water release method: sunny, the temperature above 14 °C, can be directly in the cold water. Choose the flat-bottomed duck basket and slowly dip the duck basket into the water, about half an inch deep, and it is advisable to submerge duck backs for 5 minutes. The ducklings are active when they are stimulated by cold water, eating water and activities. If it is raining, you can put water in the duck house and use pots to hold shallow water and soak in the instep. 3. The duck can be allowed to go into the water after 1 to 2 days. After the water is poured, the ducklings should be allowed to dry their feathers and then fed back to the duck. When the ducklings are released within 1 to 2 days, they should not be soaked in wet hair to avoid freezing. (2) Eating at the right time, opening the food, also known as "teaching mouth" is the first feeding. Note that do not feed within 24 hours in order to facilitate the absorption of intra-abdominal yolk. If the ducklings dry hair the next day and spin around, one-third of the ducklings will extend their heads and necks in a similar manner to food. They can then “drain†and “eat foodâ€. (3) feeding method, use rice when eating, must first wash with rice water, and mix in 10% chopped buckwheat. Teach your mouth to be patient and try to make ducklings learn to eat. Feeding times: 1 to 7 days, feeding 6 times a day, 4 times a day, 2 times a night; 7 to 21 days, 5 times a day; 21 to 28 days, can be reduced again. When feeding, groups should be divided into groups of 250 animals per group. The principle of feeding is from fine to coarse, from ripe to raw, from soft to hard, from less to more, so that quantitative, quantitative, qualitative, small meals and more feed, so as not to waste. (4) As soon as possible, “open upâ€, ie feeding animal feed as soon as possible. As the saying goes: “The goose should be green and the duck should be squeaky.†On the third day, the animal feed can be given at a rate of 10% to 20%. The snail, small fish, shrimp, cocoon, and river crab can be selected. Animal feed requires fresh, chopped and mash, and can also be fed with compound feed containing fish meal. (5) When formulating feeds, the required metabolic energy is 2 800 kcal/kg, crude protein 20%, methionine 0.4%, and lysine 11%. Vitamin a1 million units/kg, calcium 1%, phosphorus 0.7%. Reference recipe (%): 1. Corn 50, vegetable cake 20, broken rice 10, bran 10, fish meal 75, bone meal 1, shell powder 1, salt 0.5; 2. brown rice 40, corn 18, bran 3, cotton kernel Cake 5, vegetable cake 14, bean cake 10, fish meal 7, bone meal 25, salt 0.5. (6) Fill the green material. From the third day, 10% to 20% of green feed, such as buckwheat, duckweed, greens, and duckweed, were added. If you use green leaves, dandelion, comfrey, and dicot etc. as green feed, you can also prevent diseases. Strengthen management? (1) Insulation pressure prevention: temperature requirements, the first day of 32 °C, 2 ~ 7 days 31 ~ 28 °C, 8 ~ 14 days 28 ~ 25 °C, 15 days later maintained at 25 ~ 20 °C. The temperature must be maintained evenly, and the mental state of the ducklings should be observed in conjunction with changes in the outside air temperature. If the appetite is good, the feathers are smooth and tidy, evenly spread, walking high-pitched, walking freely, indicating that the temperature is appropriate; if shrinking neck, not lively, feathers erect, screaming piles, or even diarrhea, indicating that the temperature is too low, should be timely Adjustment, pay special attention to the rainy days and nights of insulation work, while paying attention to the air smooth, dry without thieves, to prevent boring death, frozen to death. (2) Appropriate density and proper illumination: 1. Density requirements 1 to 7 days 25 to 30/m, 7 to 14 days 20 to 25/m, 15 to 28 days 15 to 20/m. According to the above requirements, timely grouping and strengthening of group management. 2. Light conditions: 1 to 3 days 24 hours, 4 to 7 days 23 hours/day, and after 8 days, 1 hour per day until natural light. The degree of illumination can be lower, and it also has the effect of harming rats and animals. (3) Appropriate sports and playing water: After the ducklings have been drained, the ducklings shall be placed in shallow water for 3 to 5 minutes in batches and divided into batches, and then exercised in the windless sun. If you find ducklings trembling when you get into the water, stop immediately and dry your feathers. After the 7th day of age, when the temperature difference between the inside and outside of the duck house is less than 5°C, it takes 20 minutes to exercise. Put some sand in the stadium to allow the ducklings to feed freely. (4) Comprehensive Prevention of Diseases: Disease prevention and treatment should be prevented mainly, and do the following: 1. The entry and exit of non-essential personnel must be prohibited. Ultraviolet radiation must be used when entering, and the transportation tools can be disinfected with 100 toxins. 2. Every day, the site is cleaned, the equipment is cleaned daily, and it is regularly sterilized. The interval is 3 days in summer and 7 days in spring and autumn. 3. On the day of duckling hatching, ducklings were vaccinated with viral attenuated hepatitis virus. It can also be treated with Banlangen "three yellow" mixture. The method is to use 50 grams of Banlangen per 500 feathers, 100 grams of capillaris, rhubarb, yellow peony, and cork. 20 grams, 40 grams of honeysuckle, Jianshui Fu, a day for 3 days, also has a preventive effect against fowl cholera. Professional households adopt the above technical measures for brooding, which can train strong young ducklings, transfer them to the rearing period and the rearing of the egg production period in time, so that the breeding of ducks and ducks can achieve high yield and efficiency.
