In the brooding ducklings, the first week old Schering temperature should reach 30°C or more, then decrease with the age, and then decrease day by day. By 15th birthday, the temperature can drop to about 20°C and be constant until slaughter.
Freshly hatched broiler ducks have a 5-7 g yolk sac in their abdomen. The smaller the yolk sac, the weaker the constitution, and vice versa. If the newborn broiler duck gets the proper temperature and can drink water in time, the remaining yolk absorbs quickly. In addition, the yolk sac can provide early nutrition to ducklings.
Meat ducks grow faster after 3 weeks of age, and breast meat and leg meat develop rapidly. Therefore, it is necessary to provide high-protein and high-energy full-priced feed in the early stage. Although the crude protein in the latter stage may be lower, the energy must be increased. After 3 weeks of age, due to rapid weight gain, body weight, leg development often fails to follow, and prone to leg problems, the duck group should be rushed to move around every 2-3h.
Duck duck must pay attention to less feeding. However, after entering the fattening period after 3 weeks of age, it is necessary to adopt free feeding and free drinking water.
Because the taste of ducks is undeveloped, it is necessary to pay attention to the hygiene of feedstuffs and litter, and prevent moldy deterioration and foreign matter from mixing. Meat ducks like to eat pellet feed, do not like to eat fine and sticky feed. Ducks have innate ability to identify colors and prefer yellow feed. Ducks like to drink water in a blue sink, like cold water, do not want to drink more than body temperature water.
Fast metabolism of meat ducks, food through the digestive tract about half of 4-5h excreted from the body, and the water is only half an hour. Because the feed passes through the digestive tract fast, the rate of defecation is high, and there are also more organics and nitrogenous substances that remain in the feces. Duck manure undergoes decomposition and decomposition, resulting in a large amount of harmful gases such as ammonia. Therefore, duck dung must be removed regularly.
Ducks prefer a dry habitat. A moist environment is not conducive to winter insulation and heat dissipation in the summer, and abdominal feathers are often rotted off due to moisture and fecal water pollution. Therefore, it is very important that the duck bedding be dry and hygienic.
Ducks eat more, drink more water, and have the habit of eating by the side while drinking. In order to avoid contamination of drinking water and waste of feed, the distance between the material basin and the water basin should be more than 1m, and the middle duck stage should be more than 5m; drinking water The area requires good drainage and away from litter. In order to prevent the ducks from splashing, a net cover should be added to the basin.
Ducks are frightened, noise, color, strangers, etc. often make meat ducks appear nervous, excitement, screaming and chaos phenomenon, resulting in reduced intake and weight loss, can also cause severe crushing and death. Therefore, it is necessary to keep the surroundings of the duck house quiet.
Ducks are gregarious and like to live in groups, regardless of age. However, in order to ensure the uniformity of growth and development of meat ducks, the stocking density should not be excessive.
