When the ducklings reach the age of 3 weeks, they enter the breeding period. During this period, the feathers of the duck have basically covered the whole body, and the cold-resistance is enhanced. In addition to the cold season, no additional heating equipment is generally required. During this period, the duck's bones and muscles thrived, the digestive function was healthy, the feed intake increased, and the body weight increased rapidly. In feeding management, we must seize this feature so that ducks quickly reach the market's weight. Transition period breeding 1. Temperature. The duck house is generally not warmed, but when the natural temperature differs from the room temperature at the end of the brooding period by more than 5°C, it can cause colds or other diseases. Therefore, in the cold season, the duck house should be appropriately warmed for several days. 2. Fasting transfer. 8 hours before group transfer, stop feeding, wait until the ducks are fasting before they can turn out, but do not stop the water when they stop eating. 3. Prevent stress. On the day before the transfer and three days after the transfer, a variety of vitamins or anti-stress electrolytes should be added to the feed to prevent the effects of stress caused by colony transformation until the ducks feed normally after the colony is transferred. Change feed 1. From the first 3 days to 5 days after transferring from the ducklings house to the breeding house, the feed for the ducklings should be gradually replaced with the breeding materials. The process of refueling should not be too abrupt, otherwise it will easily lead to maladaptation of the duck or cause digestive system disorders. , thereby affecting the normal growth rate of meat ducks. In order to allow the ducks to adapt to the new feed slowly, in the production, the general reloading method is: on the first day of refueling, 30% of the bred duck material is mixed in the ducklings, and the ducklings will be bred the next day. The proportion was increased to 60%, and the proportion of bred ducks was increased to 80% on the third day. All ducks were fed from the fourth day onwards. 2. During the growth period, the meat duck has a fast growth rate and a large feed intake. Generally, providing a feed with a relatively low nutrient concentration can meet the demand. Therefore, the protein content of the feed during the rearing period is generally about 16%. Adjust the breeding density 1. The growth rate of meat ducks is very fast, reaching more than 1,300 grams at 21 days. In order to adapt to the rapid growth characteristics of the duck, the breeding space in the rearing period should be rapidly increased, the breeding density per unit area should be reduced, the production efficiency should be increased, and the specific method of adjusting the rearing density should be determined according to the rearing method. If it is adopted in the whole breeding period, it will adopt the method of rearing on the ground. In the rearing period, the shield can be removed and the stocking density can be directly adjusted to the level at the time of slaughter, that is, 5 or 6 per square meter. In the same way, if the feeding method is adopted on the web during the entire rearing period, when the breeding density is adjusted during the rearing period, it is adjusted directly to 7 to 8 per square meter, and the rearing density may be adjusted at any time according to the age of the week. If it is bred during the brooding period and the rearing period adopts the ground raising method, when raising from the web to the ground level raising, due to the sudden increase of the breeding space and the change of the ground structure, the freshly-frozen duck will run everywhere. , often sprains and turning feet. Ducks that have sprained their legs and feet, if not treated in a timely manner, will be disfigured or killed by other ducks. Therefore, for the ducks who just went down to the ground, there must be a change process when adjusting the floor space, first small and large, let it adapt to the environment and then expand the feeding space. 2. If a sprained duck is found, isolate it in time and keep it alone. After the injury recovers, the ducks will be reared in groups. When adjusting the rearing density, the ducks should be divided into small groups according to their size and strength. The weak ducks with smaller body weight and slow growth should be grouped and fed to strengthen the management so that their growth and development can quickly catch up with the same age. Strong ducks do not extend the age of feeding, affecting the date of sale. Disease prevention and control 1. Do a good job of disinfection to prevent the spread of the disease. Care must be taken to keep the duck sheds and sports grounds well drained and the ground dry, and require daily cleaning, litter replacement should be frequent, food troughs, drinking fountains should be washed frequently; in the event of infectious diseases, we must quickly isolate sick ducks, dead ducks Do not litter everywhere. Contaminated areas should be disinfected immediately. Commonly used disinfectants include: quicklime, plant-wood ash, lavender, caustic soda, No. 5 disinfectant, potassium permanganate, and 100-toxic drugs. 2. Pay attention to the dynamics of the duck and find the condition early. In the morning, at midday, midday, late at night and between feedings, it is a good time to check the ducks. Healthy ducks are physically strong, full of energy, lively and lively, with compact and shiny feathers, bright eyes and eyes, clean eyelids, strong appetite, normal feces, and stable breathing.
