1. Identification of duck seedling suppliers
Duck farms should choose the corresponding seedling suppliers according to the varieties required by different duck farms. It is required that the seedling varieties are pure, the production performance is good, the disease resistance is strong, and there is no maternal carrier, especially there can be no recessive viruses (bacteria) such as Salmonella, reovirus, adenovirus, and parvovirus.
At the same time, it is also necessary to require suppliers to have a good reputation, with the "Breeding Livestock and Poultry Production and Operation License" and "Animal Epidemic Prevention Certificate".
2. The selection of duck seedlings
First, look at the source. Seedlings are required to come from reputable and qualified suppliers, with good seedling performance, in line with the characteristics and characteristics of the required variety, and with corresponding quarantine certificates.
Second, see the seedling time. Choose the seedlings that emerge on time, if the seedlings are hatched early or delayed, it means that the embryonic development is not normal, which has a great impact on the later growth and production of the seedlings.
Third, look at the navel. The umbilicus is required to be soft, the yolk is well absorbed, and the umbilicus and anus are clean. If there is a large belly button or an unclean anus, it indicates that the chick is not in good health.
Fourth, look at vitality. Healthy chicks are lively, running around and screaming loudly. When holding the neck with the hand, the feet can struggle quickly and forcefully. When a chick is flipped to the ground on its back, it can quickly roll over and stand up. In the basket, the head of the young seedling can be raised higher.
Fifth, look at the fluff. The fluff is required to be coarse, dry and shiny. If the villi are too fine, too thin, moist, or the hairs are sticky, it is an indication that the chick is underdeveloped or in poor health.
Sixth, look at posture. The seedlings should not have appearance problems such as blindness, crooked heads, lameness, etc., and should stand attentively, steadily, and have a moderate weight.
