How to do a good job selection of geese

The method of selecting seeds for breeding geese should be carried out in the following two periods: The first time the geese are selected from 70 to 80 days of age. For the geese that have fast growth, large body size, good health, and other appearance characteristics such as feather color, which meet the requirements of the species, the number of stays should be 10% to 20% more than the planned number of species. The second choice was made at the age of 180 to 200 days of breeding geese. At this time, the breed of geese has been fully developed, and the second sexual characteristics of the geese are obvious. The male goose is required to have a large head and a large neck. The body is robust. Each part of the body is well-balanced. The wings are close to the body. The frontal sarcoma is obvious. The eyes are big, the chest is deep and the back is wide, the body length is long, the legs are wide, and the legs are wide. It is sound, loud and loud, etc. At the same time, male goose with incomplete or ill-developed penis is eliminated. The female goose is required to have a clear head and a slender neck. The body is large, and the feathers are neat, compact and shiny. The forequarters are shallow, the hindquarters are wide and deep, and the abdomen is round, with strong, strong, and wide leg spacing.

Breeding at the right age in the breeding season can maximize the benefits of breeding geese. The early mating of goslings not only affects their own growth and development, but also has poor semen quality; premature mating of female geese will lead to low qualification rate of breeding eggs and poor quality of goslings. Generally, small and medium-sized goose species need about 7 months from hatching to sexual maturity. Large-scale goose species require 8 to 10 months. And the sexual maturity of the goose is later than that of the female goose. Chinese goose has sexual maturity earlier and the European goose is sexually mature. Later.

The appropriate proportion of male and female goose breeding rates directly affects the fertilization rate of eggs. The proportion of breeding geese varies according to the variety, age, breeding method, breeding season, length of geese geese and feeding and management of geese. Generally, the ratio of male to female of small-scale gooses is 1:6 to 1:7, the ratio of male to female of medium-sized goose species is 1:4 to 1:5, and the ratio of male to female of large-scale goose species is 1:3 to 1:4. The number of goslings should be appropriately reduced when young male goose and old-age goose are involved in mating, and the number of goslings may be appropriately increased when the age-appropriate goose is engaged in mating. Before the breeding season arrives, the gregarion can be appropriately advanced and the number of goslings at the beginning of the gregarion can be appropriately increased. Under good husbandry and management conditions, the number of goslings, especially when grazing, can be appropriately reduced.

The way of breeding breeding geese is divided into natural breeding and artificial breeding. Natural breeding refers to the placement of a certain number of male geese in the geese so that they can freely mate. When the male goose body size is larger and the goose body size is smaller, when natural breeding is difficult, manual assisted breeding is required. In the use of large-scale goose as male parent for crossbreeding, it is often necessary to adopt this breeding method. When implementing manual assisted breeding, the operator should first put the male and female geese together, familiarize them with each other and perform breeding training. After the conditioned reflexes of the mating are established, the female goose is pressed to the ground and the abdomen is touched by the ground. With the head facing the operator and the tail facing outward, the male goose will come forward to climb.

Useful life In general, the production of female geese increases from year to year, and starts to decrease in the fourth year. In other words, female breeding geese can generally use for 3 to 4 years. There are also some small early-growth goose species, such as Taihu Goose in our country and Kuban goose in the former Soviet Union, whose eggs production is highest in the first year. These geese can only be used for one year and they are all eliminated when they start moulting at the end of the laying season.

In order to ensure the high yield and stable production of geese, proper age structure should be maintained when selecting geese. The average age of the geese population is 1 year old female geese account for 30%, 2-year-old goslings account for 35%, 3-year-old goslings account for 25%, and 4-year-old goslings account for 10%.

Hyaluronic Acid Eye Drops Sodium Hyaluronate (HA), Pure Hyaluronic Acid could be used in eye surgery, such as Hyaluronic Acid Eye Drops, corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment.

Eye Drop Grade Hyaluronic Acid Powder is an important component of intercellular substance, eye vitreous body, joint fluid and other connective tissue. It acts the important physiologic roles in holding body's moisture, maintaining extracellular space, adjusting osmotic pressure, lubricating and promoting cells to repair in the body. Sodium Hyaluronate can be used as viscoelastic agent inintraocular lens implantation operation, as the filler in the osteoarthritis and rheumatoid arthritis and otherjoint surgery, as a medium widely used in eye drops, it also can be used to prevent postoperative adhesion and facilitate the wound heal. The compounds formed by the reaction of Sodium Hyaluronate with other drugs play a drug release effect role, thus achieve the purpose of drug targeted and time controlled release.

With the development of medical technology, Sodium Hyaluronate has been more and more widely used in medical applications. In 1976, Sodium Hyaluronate was first commercialized and used as ophthalmic viscoelastic agents, which is a significant progress in the ophthalmic industry. In 1987, Sodium Hyaluronate for intra-articular injection came in to the market. In 1990s, the large-scale production of Sodium Hyaluronate by fermentation made the cost lower, thus products containing Sodium Hyaluronate such as eye-drops, dermal fillers and other Sodium Hyaluronate preparations started to be used extensively.
