Breeding techniques of Mallard Duck

Mallard duck culture has four major characteristics: first, the disease resistance is very strong. Second, a wide range of eating habits, rice, corn, wheat, bran, withered cake, fish meal, silkworm pupa and green, roughage and fresh animals, are very fond of eating. Third, the growth is extremely fast, green-headed wild duck meat can be put on the market after it is generally raised to the age of 70 days, and its weight reaches 14 kg, which is 2-3 times larger than that of ordinary wild ducks. Fourth, it is extremely rich in nutrition, with low fat, high lean meat rate, fresh and tender meat and fragrant game, which is a first-class nourishing delicacy. Therefore, the prospect of raising mallard ducks is very broad.

Culture environment

The construction of wild duck farms must conform to the wild habits of wild ducks. Half of the sheds should be used as lounges and half for open-air activities, which should be ponds or artificial pools. Some trees and grasses can be planted on the activity field, and some algae can be planted in the pond. If the method of combination of cultivation and release is adopted, the farm must be built in places with open waters and lush vegetation, such as rivers and lakes. Purse seine and Skynet should be built at the same time. Skynet is about 2 meters high from the water surface or the ground, surrounded by a purse seine to the bottom, and connected with Skynet to form a closed body to prevent wild ducks from fleeing.

The hole of Skynet and purse seine is 3 × 3 cm, either with nylon net or rope net. Generally, the feeding area of every 100 wild ducks is 1: 30 days old, and the area of the house is 5-7 meters. The sports ground and the water field are 20 meters each. Over 70 days old, 15-20 meters in area, 20 meters in sports ground, 15 meters in water field.

Feed selection

The feed nutritional requirements of mallard ducks are basically the same as those of domestic ducks. Under normal circumstances, full-price pellet feed for domestic ducks can be fed. If prepared by ourselves, the feed reference formula is as follows: 130 days old. Corn 47.3%, wheat 15%, wheat bran 10%, bean cake 22%, fish meal 4%, shell meal 1.5%, salt 0.2%. At the age of 31-70 days, corn 40.8%, wheat 14.5%, rice bran 17.5%, rice 8%, bean cake 14%, fish meal 4%, bone meal 1%, salt 0.2%.

Feeding and management

1. Feeding and management of ducklings (1 ~ 30 days old)

The suitable temperature for raising ducklings should be 29 ℃ at the age of 3 days, 26 ℃ at the age of 6 days, 25 ℃ at the age of 10 days, and 19 ℃ after 10 days. Generally, brooding in flat ground, the ground should be covered with soft straw, and separate small columns, each column is about 2 meters, each column is equipped with a thermal insulation lamp, raising 50 ducklings per small column within 7 days. As the ducklings have the nature of sleeping in the heap, someone should be on duty day and night, gently fiddling with the pile every 1 hour to prevent crushing and suffocation. Adjust the density after a week.

When eating, drink water before feeding, and add an appropriate amount of compound vitamin B preparation to the drinking water. To prepare enough clean water to drink freely, do not cut off the water. The times of feeding are generally 7 times a day within 10 days of age, and 4-5 times a day after 10 days of age. Each time, green fodder such as tender grass, vegetable leaves, kelp fine powder and fresh animals such as small fish and shrimp, field snail meat, clam meat and earthworms should be properly added to facilitate the growth of ducklings.

2. Feeding and management of adult ducks (31 ~ 70 days old)

In order to make adult ducks gain weight rapidly, there is no limit to the supply of formula feed during the whole feeding period, allowing them to eat freely, as well as sufficient clean drinking water. After 50 days of age, adult ducks begin to learn to fly due to increased body fat and physiological changes, so they must strictly prevent escape. Breeders should wear plain clothes to prevent outsiders from entering the yard so as not to disturb the ducks.

3. Feeding and management of breeder ducks (after 70 days old)

Press 1 ∶ 4: 6 to select good male and female ducks. Male ducks should choose those with strong physique, lively action and quick response, while female ducks should choose those with small head, long neck, big eyes, wide back and wide chest. The feed can be fed with egg duck or breeder duck at full price, and 6%-8% kelp powder is added to the feed. The times of feeding during the peak laying period should be increased in order to achieve high and stable yield. During the whole laying period, some shallow nests can be built artificially on the ground and covered with some soft straw to facilitate the laying of female ducks.
