The Warmth Of Goose Feathers Is Very Good

Goose feathers are a big item of goose income. According to their use value, mainly divided into the following four categories: 1, wings big goose feathers (called the main wing feathers): ancient for dipping pen, but also the production of geese feathers the main raw material, Goose Feather white goose feathers dyed a variety of colors.

The body surface of the goose is close to the body of the goose feathers. Large goose goose feathers are loose. Medium and small goose goose feathers are tight. Goose goose feathers according to their different parts, down the different shapes and structures, the goose goose feathers are divided into positive feathers, feathers and fiber feathers, velvet feathers 4 species. Positive feathers are covered in the bulk of the body of the geese feathers. Goose is waterfowl, feather Feng cashmere, especially the plumage more developed, Goose Feather commonly known as goose down, this goose feathers in the feathers below. Fiber feathers mixed in the feathers, fiber feathers as fine as hair, it is also known as hairiness, feather axis hard, poor insulation performance. Cashmere feathers between the feathers and feathers, it is also known as half velvet feathers, the upper part of the pinnae, the lower part is the less rare feather feathers. Goose goose feathers vary depending on the variety of goose, there are two varieties of white and gray. White feathers more varieties, the north and south of China more white goose, the south to gray goose more common, less white goose. From the surface of the goose body was feathers, in fact, goose feathers born in a certain area of the body surface. There are geese feather area called feather area, no goose feathers area said bare area. At the same time, Goose Feather the proportion of different parts of the goose production of different parts, according to the relevant departments to determine the 12-year-old Wanxi white goose spring slaughter dry results: each goose average yield accounted for 6.34% of body weight, 285 grams, The weight of the belly, the back, the leg and the neck were 18.12%, 10.59%, 24.43%, 4.69% and 12.85% respectively, the weight was 51.63 g, 30.18 g, 69.63 g, 13.38 g and 36.63 g, Chest down production more, less legs.

Goose feathers are made of protein, which accounts for about 85% -90% of the keratin in the protein that constitutes the goose feathers. This protein was originally synthesized with the formation of keratin with hair follicle formation. Goose feathers are derived from the skin, the first to form hair follicles, resulting in feathers, feather root and dermis formation of geese feathers nipples, blood vessels into the feathers, feathers are rich in blood vessels and full of gelatin-like material, goose feathers in the growth process In the nutrition needed to supply through the feathers, Yu Lang accompanied by the growth of geese and feathers. Goose feathers mature, the blood vessels from the upper part of the feathers began to shrink, degeneration, and gradually moved back to the feathers. Goose feathers are not ripe, feathers filled with blood vessels in the feather market, was red, Goose Feather commonly known as vascular hair. Goose feathers mature due to vascular atrophy, feathers were white.

Goose feathers in the fertilized eggs hatch to the first 10 days can be seen with a magnifying glass geese feathers are distributed throughout the body part of the body, 14-15 days all torso villi, the first 17 days the body has fluff, in the next 13 days in the hair Growing mature, shelled goslings A golden fluff, with very thin feathers, only a few small feather branches at the top, the weight is very light, Goose Feather but the warmth is particularly good. The growth rule of goose feathers due to the different varieties of geese, the first day of hair change slightly different, such as Lai Chuan too hybrid goose, "wings" age between 55-60 days.

Goose feathers change the process of change, subject to genetic, environmental and nutritional conditions, the amount of protein in the feed, a direct impact on the growth and replacement of geese feathers. Especially the amount of sulfur-containing amino acids in the feed, a direct impact on the growth and development of geese feathers. Because synthetic keratin mainly rely on sulfur-containing amino acids, namely, leucine and methionine. Goose Feather Tartine is the main ingredient of keratin. Can be directly involved in the synthesis of keratin. Methionine can be involved in the synthesis of keratin by conversion to urethane. Swallow growth should account for about 54% of total amino acids during the growth of goose feathers. After the growth of the goose feathers, the demand for udolines can be reduced.

The growth and development of goose feathers is accompanied by the growth and metabolism of the whole body, so in the diet should not only consider the nutritional needs of goose feathers, but also consider the nutritional needs of the whole body, in the nutrient shortage when the feathers grow slowly , But priority over the growth of muscle just S fat, past the habit of raising the hanger in the past, the formation of the body of the goose goose Qi, but the body without meat, before the listing must be friends, this method is not desirable. Goose Feather Geese feathers growth process is normal, can be used to check the feeding and management measures are reasonable, so the masses are very seriously.
