In recent years, many duck farmers have summed up the “four sentences†in the long-term breeding practice, which has played a good role in saving feed and increasing egg production. The annual egg production of each duck is from 250 to more than 300 eggs. Each egg weighs 60 grams and saves more than 20% of the feed. The four-year-old ballads for breeding are: (1) The spring duck's skill has proven that early spring, early feeding of ducks, early, large, large and thin ducks lay eggs late Therefore, the spring must be carefully fed. The commonly used feed formula is: corn 30%, broken rice 20%, wheat 15%, bran 5%, rice bran 14%, rapeseed cake 8%, fish meal 8% Each day, each duck feeds 100 to 125 grams of compound feed, and then feeds 150 to 200 grams of green feed. This way, the female duck feeds on fat, and the eggs are numerous and large. (2) In summer, it is necessary to pull the hair into the summer, especially in summer. The female duck has poor appetite and body condition because of continuous egg production for several months. If it continues to lay eggs, it will inevitably affect autumn eggs, and it cannot withstand the blows of autumn rain. At this time, the mother duck was shut up, and several wing hairs (big hairs) on the wings and tail were pulled out. He only fed water for three consecutive days. He did not feed and forced to stop production. Then it took off the old hair and fed the concentrate. After about 20 days, the female ducks recovered quickly and replaced with new hair. After about 30 days, the female ducks continued to produce high yields. (3) Fall control of ducklings in autumn, all kinds of pastures and seeds, after rice harvest, more grain is plucked, and the grazing food is abundant. At this time, it is necessary to control the ducks. The drive can be adopted to drive the ducks to a weight of 1.5 to 1.5. 2 kg. Because of weight gain, the accumulation of fat is bound to increase, and egg production will decline. Keeping the mother duck on the upper side of the fat, the whole fall will be stable and high yield. Autumn is the best season for processing and changing eggs. it is good. (4) Noise in winter ducks are often cold in winter. Ducks often do not love activities, increase their fat, and reduce their egg production. In order to produce more eggs for female ducks, in addition to reducing fine material and increasing green and coarse materials, Drive ducks (ie, noisy ducks) and gently sip them so that the ducks stand up. Then slowly drive the ducks to make circle movements in the shed. Turn 5 to 10 laps at a time and duck at least 5 times a day. There is a pool or canal. Ponds and libraries can also be arranged for a launching event, but the ducks must be allowed to move under the front of the next time, so that the body of the ducks should be warmed up and their ability to keep out the cold should be improved. When the water is spent in the water for more than an hour, the ducks must be allowed to go ashore and enter the shed. After the ducks made a circle movement, most ducks could make a strong shout.
