Careful selection of good duck breeds When the duck neck is lifted, both feet are stretched downwards, and each toe is stretched, not dancing; the eyes are big and bulging, the mouth is long and wide, the upper eyelid is prominent, the neck is long, and the back is Large, neat and shiny feathers; Cloaca loose and moist; Late plume, short time, few and lively; Eggshell hard, oval and shiny, such ducks are high yield ducks. There are two bogey for young duck feeding Young ducks refer to bred ducks that have not been produced. Ducks at this stage during the feeding process have a high protein content in the diet, resulting in premature senescence and an unsustainable egg production period. Can be fed more roughage and green juicy feed to prevent premature sexual maturity. Second avoid feeding granular feed. Feed for young ducks is best done with mixed powders, as pelleted feeds can stimulate appetite and can easily cause overweight of young ducks, which is detrimental to their subsequent production. In the mother duck group, in addition to leaving enough male ducks, an additional 2% of male ducks are reserved. This enhances the libido stimulating effect of the male duck on the female duck, can promote the sexual function of the female duck, accelerate the development of the follicle, accelerate the ovulation and achieve the purpose of producing multiple eggs. When the mother duck begins to lay eggs, use 1 kg of honey to mix in 50 kg of feed. Feed it continuously for 3 days. After stopping for 2 weeks, feed the feed for 3 days. This method can not only prevent duck gizzards, but also increase the egg production rate. Enhancing stocking during the rearing of ducklings Let the ducklings eat aquatic animals such as small fish, shrimps and quails in the fields, canals, and ponds. When the stocking period is reduced, the ducks should be given some fishmeal and appropriate amount of Vitamins, so that the mother ducks can also produce more eggs. Timely calcium prolific egg Ducks should be calcium at the age of 15 weeks. The ratio of calcium source to lime and shell powder is 2:3, and 1% bone meal should be fed to increase the strength and smoothness of the eggshell. It is advisable to make up 2.5% of the dietary calcium, and gradually increase it later. When the egg production rate is below 65%, the calcium content in the diet is appropriate at 2.5%. When the egg production rate is between 65% and 80%, the calcium content is 3%. When the egg production rate is above 80%, the calcium content is To reach 3.5%. Should ensure that the dietary vitamin D supply, and control the ratio of calcium and phosphorus is 5-6.5:1, according to the level of egg production rate, to ensure that 14-17 hours of sunshine, in order to facilitate the formation of vitamin D in the body, is conducive to calcium Absorption and utilization, increase egg production rate.
Probiotics are a kind of active microorganisms that are beneficial to the host by colonizing in the human body and changing the composition of a certain part of the host's flora. By adjusting the host mucosa and system immune function or by adjusting the balance of the intestinal flora, promoting nutrient absorption and maintaining intestinal health, thereby producing single microorganisms or mixed microorganisms with a clear composition that are beneficial to health.

Probiotics participate in a variety of cyclic processes in the water body. Through their own metabolism, they consume organic substances in the water and reduce the concentration of nitrite nitrogen and ammonia nitrogen in the water body, thereby achieving the effect of improving and maintaining good water quality.
