The main points of raising wild ducks in adolescence

Wild duck is a typical representative of waterfowl, which is the common name of mallard duck (mallard) in the northern hemisphere. Wild duck belongs to bird class, goose-shaped order, duck family; its number is very large, is the popular name of many kinds of wild ducks, there are more than ten species. Wild ducks can make long-distance migration flights, with a maximum speed of 110 kilometers per hour. In a narrow sense, the wild duck is the mallard duck, which can be eaten for more than three generations. Wild ducks in a broad sense also include many national first-level protected animals. There are many kinds of wild ducks, and there are about 10 species in China, each of which is quite different from the feathers of male ducks. at present, the main breeds of wild ducks raised at home and abroad are mallard ducks. So how to raise wild ducks in adolescence? What should I pay attention to?

Young wild duck refers to 31-70-day-old ducks, the breeding stage of wild ducks mainly grow feathers, muscles and bones, is the period of fastest growth and development, the average daily weight gain of each duck is the largest, and the feathers are basically completed at the age of 40 days, leaving only a little fluff behind the head. Under good nutrition and management level, 60-day-old can reach the peak of weight growth. Need more nutrients, this stage of the wild duck foraging ability, digestive ability and the ability to adapt to the external temperature are greatly enhanced, generally can live in the duck house at room temperature, in case of a sudden change in temperature can take appropriate measures to keep warm.

The main results are as follows: (1) before the wild ducks are divided into groups, wild ducks should be selected according to their physical strength and size, and severely disabled individuals should be eliminated before they are transferred from the brooding stage to the mature stage.

(2) the feeding density of wild ducks: 10-15 ducks per square meter.

3 prevent quarreling shed: noisy shed refers to 60-70-day-old wild ducks. Due to the increase of body fat and physiological changes, wild ducks occur in the wild and stimulate flight. The ducks are agitated and restless, neurotic and do not seem to feel hungry. Sharp reduction in food intake, resulting in weight loss, in case of stress, can also stimulate noise shed.

Preventive measures:

1) limit feeding and increase the amount of roughage

2) Breeders avoid wearing bright clothes in the fence

3) avoid disturbing ducks, especially from outsiders

4 put into feed

The main results are as follows: 1) feeding characteristics: the body weight of mallard duck increases the fastest in the breeding stage, and the requirement for feed also increases rapidly. at the same time, its appetite and digestive ability increase significantly, and it can resist rough feeding, which can reduce concentrate feed such as cereal feed and animal feed, and appropriately increase bran, wheat bran feed, aquatic plants and green feed, so as to adapt to its wild diet, but there can be no lack of minerals and vitamins. Especially at the age of 40-60 days, restricted feeding should be implemented, that is, properly reducing protein feed and energy feed, and increasing coarse fodder such as bran, bran, aquatic plants and green fodder, which can postpone and reduce the wild attack of wild ducks, which can not only reduce the resulting loss, but also save feed, otherwise, wild ducks accumulate fat rapidly, stimulate their flying wild, and lead to noise.

2) careful feeding: outdoor feeding, in order to keep the duck house clean and hygienic, using matching diet, regular ration, feeding 3-4 times a day, daily feeding amount is 5% of its body weight, the feeding amount must ensure that each duck can be late for food, and there is no leftover food. If grazing and feeding, it is necessary to extend the grazing time as far as possible to make it late for more and more complete food. after grazing, decide whether to supplement and feed according to the situation of feeding. If it is used as a backup breeding duck, it should be appropriate to increase the green succulent feed, the dosage accounts for about 15% of the feed, in order to properly control the weight, 30-40 days before delivery can be increased to 55%, 70%, and 20%, 30%, respectively. Concentrate accounts for 10%, 15%, control meat feed to prevent preterm delivery.

5Lighting control: at this stage, care hours should be reduced and combined with feed restriction to make controlled maturity more effective.

6 exercise and bathing: after 40 days of age, except for bad weather, it can not be locked up in the duck house at night, allowing it to stay free overnight, on the one hand, it can maintain its wildness, maintain the delicate game of meat, and on the other hand, it can also exercise its gregariousness. overcome the lack of nutrition in feed formula, improve physique and reuse value.

7 escape prevention: at the age of 50 days, the wild duck basically grows its wing feathers and begins to learn to fly. Skynet and purse seine must be set up around the playground and water surface, with a metal or nylon net at the top to prevent flight, and the fence or net should be deep to the bottom of the river to prevent absconding.

8 selection of wild ducks: 60-70 days old, breeding according to the ratio of male and female (4-6): 1, the female duck should have a small head, long neck, big eyes, and the male duck should be big, strong and flexible. The rest of the wild ducks are sold as meat ducks or after fattening.

Clean the house every day, change the bedding and ventilation frequently, keep the water clean and hygienic.

When the temperature is high, we should pay attention to preventing heat and cooling.

Make sure every wild duck has a feeding place.

Pay attention to prevention and control of diseases
