The temperature in autumn is suitable for forage grass, rich duck brooding and fattening matters.

After entering autumn, the temperature drops slowly, at the same time, after the rice field is harvested, it also frees up the site, which provides conditions for adult ducks to fattening. At the same time, autumn is also suitable for duck brooding, after autumn brooding, the incidence of disease is low, the survival rate is high, raised to about 60 days, can be out of the fence.

Duck

Filling and fattening

It is through the excessive supply of heat and protein to make ducks gain weight rapidly in a short period of time. When ducks grow to 50-60 days old and weigh about 1.5 kg, they can begin to be fed. The weight of ducks can be increased to more than 2.5 kg in a short time by feeding 12ml for 14 days in autumn.

Filling feed: the early feed is mainly rice bran and wheat bran, with the right amount of corn and bean cake, with appropriate vegetable leaves, and the crude protein level is about 15%. Then gradually reduced the bran feed and increased the protein and starch feed. The formula for the last seven days: 58% corn, 22% wheat flour, 7% wheat flour, 10% soybean cake powder, 2% bone meal, 0.44% salt and 0.54% trace elements.

Note: fill in and feed regularly. Fill it out three times a day and night, once every 8 hours. Before each feeding, the digestion of ducks should be checked. If there is still stagnant food in the neck, stop feeding or fill less, and add yellow soda tablets in drinking water. It is necessary to provide adequate clean drinking water in time and release water properly; keep the duck house hygienic, keep the environment quiet, dim light, not rough driving and loud noise, avoid causing stress reaction of ducks, reducing appetite and affecting fattening.

The temperature is repeated in autumn, when there is a high temperature, pay attention to heat prevention and cooling, keep the duck house ventilated, cool and comfortable; build a shed or plant trees in the playground.

Autumn brooding

First of all, the density of ducklings is less than 30 ducklings per square meter. The density is too high, and the ducklings lack of activity space, which leads to the decline of physique and disease resistance.

Secondly, install the ventilator and keep the air warm and ventilated reasonably. After 5 days old, the intake and drinking water of ducklings increased, and so did the excretion. During this period, in addition to excluding ammonia and other harmful gases, heat preservation is also very important, the use of feeding or when the noon temperature is high.

Ducklings

In addition, duckling feed is very important, and the quality of the feed depends on whether the energy-protein ratio is balanced. Because the initial physiological system, nervous system and digestive system of ducklings are not mature, the opening feed of ducklings must be nutritious, healthy and palatable to meet the growth needs of ducklings.

Autumn climate is changeable, hot and cold alternately, ducklings are susceptible to a variety of bacterial and viral diseases, and spread to each other. Usually avian cholera, duck serositis, duck plague, duck viral hepatitis will bring losses. Must be more important than prevention, prevention is more important than cure. In breeding, the environment should be strictly controlled, the temperature should be maintained, the ventilation should be unobstructed, harmful gases and pathogenic microorganisms should be prevented from gathering in the duck house, duck seedlings should be immunized with duck plague, duck hepatitis and duck serositis, and ducks should be provided with enough activity space to enhance their immunity. feed, drinking water and duck houses should all meet the hygiene standards.
