The duck brooding can be divided into three types: the head duck, the summer duck, and the fall duck. In general, it is better to feed the first-row ducks, followed by the summer-water ducks, and the fall ducks. Spring brooding has practical problems such as unstable temperatures, frequent cold waves, excessive rainfall, and difficulty in raising ducklings. Practice has proved that incubating young ducklings in the spring requires only paying attention to warmth and moisture, strengthening feeding and management, and the feeding problem is not too great.
In general, ducks should be brooded during the period from clearing to trough, and they should be prepared with high-quality full-price feeds, brooding rooms and clean utensils. Use caustic soda lime chlorine preparations and other disinfection, ready for thermal insulation equipment. The ducklings should be given a suitable amount of glucose or vitamin C or one thousandth of potassium permanganate in drinking water 24 hours after hatching, and can be eaten after serving for 1-2 hours. Full-priced feed can meet the nutritional needs of ducklings, ducklings, digestive tract unsound less feeding to feed, feeding, feeding, six or seven percent full, feeding 6-8 times a week, plus feeding 1-2 times after dinner gradually reduce the number of meals.
Temperature is the main technical measure for brooding ducks. When the ducklings are at one-day age, the actual temperature under the warmer should be maintained at 30-32 degrees, and the room temperature should be maintained at 22-24 degrees. Afterwards, the ducklings will decrease by 1 degree every day until they increase by day, until Consistency with the ambient temperature no longer cools. The breeding density of ducklings is preferably 20 pigeons per square meter in one week, and no more than 10 plumes per square meter in the future. The density is too large to waste the space, and too small will affect the growth. It is advisable to group a group of 250-300 pigeons. The duck house should be kept clean and dry. The air is fresh and it should be changed 2-3 times a day for 10-20 minutes.
Ducklings are to carry out water-draining activities. Ducks are waterfowl and their living environment cannot be separated from water. Ducklings are usually released within 2-3 days after hatching. They release water 2-3 times a day for 10-15 minutes each time. Ducklings in summer and autumn and one week of age discharge water 4-6 times a day, 20-times each time. For 30 minutes, ducklings older than one week must not be allowed to drip in the hot sun and can grazing in the water all day long. The ducklings hatched, and after feeding for 78 days, they drove into the green manure fields, rape fields, broad bean fields, and green manure fields in the ploughing fields. They allowed them to grazing on the muddy, roach, yellow pecker, small fish, and shrimps in the fields. Insects and other natural animal feed.
By the time the early rice is harvested, egg-type female ducks begin to lay eggs and the ducks can be marketed. For ducks with both egg and meat use, it is possible to use the "double rush" and the golden opportunity for the harvest of rice and worms during the harvest of a single season of rice.
Coarse grain usually refers to rice, wheat, corn, soybean and potato five crops other than the grain and bean crops. The main are: sorghum, millet, buckwheat (sweet buckwheat, buckwheat), oats (naked oats), barley, millet, barley millet, barley millet, grain amaranth and beans (kidney beans), mung beans, adzuki beans (adzuki beans, adzuki beans), broad beans, peas, cowpea, lentils (soldier beans), black beans and so on. It is characterized by short growing period, small planting area, special planting area, low yield, and generally contain rich nutrients. The ancient Chinese medicine book "Huangdi Neijing" records that "five grains are for raising, five fruits are for helping, five livestock are for benefiting, and five vegetables are for filling". Some trace elements, such as iron, magnesium, zinc and selenium, are more abundant in coarse grains than in refined grains. The value of these trace elements to human health is considerable. Coarse grains are also richer in potassium, calcium, vitamin E, folic acid and bioflavonoids than refined grains.
Whole Grains are rich in nutrients. Oats, for example, are rich in protein; Millet is rich in tryptophan and carotene. Beans are high in quality protein; Sorghum is rich in fatty acids and iron; Tubers contain carotene and vitamin C. In addition, coarse grain still has the effect of reducing weight. Such as corn also contains a lot of magnesium, magnesium can strengthen intestinal wall peristalsis, promote the excretion of body waste, is very beneficial to weight loss.
