The Growth Process Of Goose Feathers

Goose feathers are a unique derivative of goose skin, play a protective role. According to its structure is generally divided into three kinds: positive feathers, feathers, fiber feathers. The feathers are the most conspicuous feathers of the goose, and the mature feathers are divided into flying feathers - it includes wings - dead Ji Yu and aileron feathers, tail feathers on the tail; body feathers in the trunk, neck, legs and other parts. Is the middle of a feathers, the lower section of the feathers, buried in the skin of the feathers, Goose Feather the upper section of the stems, stems on both sides of the raw feathers, pinna by a number of parallel branches of the composition of the feathers And born with two rows of small feather branches, small feathers on a small fishing, intertwined with each other to form a pinna. There is no feather feathers, only a very short and thin feather stems, feathers longer, small feathers on the little hook, so like a velvet radiant shot fine velvet, was dome, also known as velvet The In the goose body close to each of the feathers are built with a thin soft feather feathers, it grows in the inner body of the goose body, close to the skin, from the thermal insulation effect. Fiber feathers are single branches of the feathers, characterized by soft and long, mainly born in the front of the plum layer of plumage feathers.

Goose feathers in the composition of protein accounted for 89% -97%, it can be said that goose feathers are composed of protein, in the composition of geese protein in the keratin protein accounted for about 85% -90%. This protein was originally synthesized with the formation of keratin with hair follicle formation. Goose feathers are derived from the skin, the first form of hair follicles, resulting in feathers, feather root and dermis formation of goose 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 nutrient needed to supply through the feathers, Goose Feather Yu Lang accompanied by the growth of the feathers and extension. Goose feathers mature, the blood vessels from the upper part of the feathers began to shrink, degeneration, and gradually shrinking to the feathers. Goose feathers are not ripe, feathers filled with blood vessels in the feathers, was red, 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 magnifying glass geese feathers are distributed throughout the body part of the body, 14-15 days all the trunk has fluff, the first 17 days the body has fluff, in the next 13 big The villi continue to grow mature, shells of the goslings a golden hair, a very thin feathers, only a few small feather branches at the top, the weight is very light, but the warmth is particularly good. The growth rule of goose feathers due to the different varieties of goose, 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, the direct impact of the growth and replacement of geese feathers. In particular, the amount of sulfur-containing amino acids in feed, a direct impact on the growth and development of geese feathers. Because synthetic keratin mainly rely on sulfur-containing amino acids, namely, Goose Feather leucine and methionine. 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 θ‚®aline can be reduced.

The growth and development of goose feathers is accompanied by the growth and metabolism of the whole body and the metabolism, so in the diet should not only consider the nutritional needs of goose feathers, but also consider the nutritional needs of the 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 of rural habitat, the formation of the geese for the whole body of wool, but the body without meat, before the market must teach friends, this method is not desirable. Geese feathers growth process is normal, can be used to check the feeding and management measures are reasonable, so the masses are very seriously.

Geese geese initial processing

The initial processing of goose feathers refers to the process of cleaning, sorting and packaging the goose feathers. First, the goose feathers into a 1-2% of the caustic soda solution filled with a dip, the next day stirring cleaning, with the wash with the water to remove the feathers on the grease, blood and dust. Marsh clean after drying or drying, and classification and packaging.

Geese goose feathers can be divided into large tail feathers, large wing feathers, chest, back, body side, tail, neck pieces of feathers and feathers and other four species. After the above-mentioned clean and dry goose feathers can be classified according to their classification. When packing, pay attention to "Flying Si" and "blackhead". "Flying silk" refers to the feathers and feathers from the fall off the broken feathers, the main house when the improper operation. "Blackhead" Wu refers to different color plush. Goose feathers to mouth regulations, "Flying Si" content of not more than 10%, "black" amount of not more than 2%. Therefore, the distribution of goose feathers should try to remove the "Flying Si" and "black".
