How to distinguish muscovy ducks?

Reproductive characteristics of muscovy ducks

1? . perform

Muscovy ducks with different feather colors have different reproductive performance. The reproductive performance of muscovy ducks with different coat colors is shown in Table 7? .

2? Seed selection

Selecting excellent breeding ducks is very important to improve the production performance and economic benefits of muscovy ducks. Under the same feeding and management conditions, the ducks are excellent, produce more meat and eggs, and have low feeding cost. Therefore, breeding is the first step in the process of raising ducks. Breeding ducks requires obvious breed characteristics, good development and strong physique. Appearance is an important feature of varieties. Male muscovy ducks should be big, dignified, well developed, strong males, straight and wide backs, and rectangular. The mother duck should be big, wide and round, with full chest, moderate fat and thin, short feet, deep abdomen and high egg laying rate.

In addition, comprehensive comparison should be made according to the economic characteristics such as egg laying rate, meat production rate, reproduction rate, birth length, meat-feed ratio, slaughter rate, liver-feed ratio, fertilization rate, hatching rate of breeding eggs and survival rate of ducklings.

3? . Mating age and proportion

The sexual maturity of muscovy ducks in China is 6? ~? 9? At the age of months, the sexual maturity of male muscovy ducks is later than that of female muscovy ducks. The sexual maturity of French muscovy ducks is late, about l? Last month. Natural mating, the mating ratio of male and female muscovy ducks is generally 1? ：

7? ~? 8? , but it varies according to the age of the month (Table 8? )。

4? Service life of breeding ducks

The use period of muscovy ducks is not long, and that of male ducks is generally 1? ~ 1.5 years. After breeding for one year, drakes are weak and their reproductive performance declines. Therefore, in order to reduce the feeding cost, it is best to use 1? It will be eliminated after the year, and Drake will be chosen every year. The service life of female duck is longer than that of male duck, and it can be used for 2? ~? 3? A few years. However, with the increase of age, the nesting ability of female muscovy ducks increases and the egg laying ability decreases. According to reports, foreign countries generally only use 2? An egg laying cycle, and then eliminated as a commercial duck for sale, at this time the meat value of the female muscovy duck is still good. The breeding density of breeding ducks is 250.

~? 300? Only one group is better. 60% female ducks in a flock 1 year? ~70%? ,? 2? Female ducks account for 20%? ~? 30? %。
