example 1

[0010] Example 1: First, place a healthy goose with full feathers in a dark, dry, hygienic and quiet environment, and control its nutritional intake, that is, cut off water and food; then, after the nutrition control, the weight of the goose has dropped by 25% , the body temperature dropped by 0.4°C and began to classify and collect flake feathers, down feathers and wing feathers; finally, after the feather harvesting was over, the geese gradually resumed their nutritional supply to conventional feeding management, that is, restored 30% of the daily ration supply on the first day after feather harvesting, Increase by 10% until 100%. Among them, the normal water supply is restored after adopting 0.9% salt water for free drinking in the first three days, and the geese can take a bath after 72 hours after plucking feathers.

[0011] Example 2: First, place a healthy goose with full feathers in a dark, dry, hygienic, and quiet environment, and control its nutritional intake, that is, cut off water and food; then, after the nutritional control of the goose, the body weight drops by 30%. The body temperature dropped by 0.8°C and began to sort and collect flake feathers, down feathers and wing feathers; finally, after the feather harvesting was over, the geese gradually resumed nutrient supply to conventional feeding management, and restored 30% of the daily ration supply on the first day, and then increased it by 15% every day until 100%, among which, 0.9% salt water was used for free drinking in the first three days, and the normal water supply was restored later, and the geese could take a bath after 72 hours after plucking feathers.

example 3

[0012] Example 3: First, place a healthy goose with full feathers in a dark, dry, hygienic, and quiet environment, and control its nutritional intake, that is, cut off water and food; then, after the nutritional control of the goose, the weight of the goose has dropped by 40%. When the body temperature dropped by 1.0°C, we began to sort and collect flake feathers, down feathers and wing feathers; finally, after the feather harvesting was over, the geese gradually resumed nutrient supply to the conventional feeding management. The daily ration supply was restored to 30% on the first day, and then increased by 20% every day until 100 %, wherein, among them, 0.9% salt water was used for free drinking in the first three days, and normal water supply was restored later on, and the geese could enter the water for bathing after 72 hours after picking feathers.

Abstract

The invention discloses a method for collecting goose feathers through artificial nutritional intervention. First, a healthy goose with complete feather growth is placed in a dark, dry, hygienic, and quiet environment, and the nutrient intake is controlled, that is, water and food are cut off; and then After nutrition control, the weight of the geese drops by 25-40%, and the body temperature drops by 0.4-1.2°C, and the classification of flake feathers, down feathers and wing feathers begins to be collected; Recover 30% of the daily ration supply on the first day after feathering, and increase 10-20% to 100% every day thereafter. Among them, 0.9% salt water is used for free drinking water in the first three days, and normal water supply is restored later. Then you can go into the water to take a bath. The invention adopts artificial nutritional intervention to cut off the nutrient supply of goose feathers, so that the feathers are dry and easy to pull out, which not only overcomes the shortcomings of scalding and picking feathers, live feather pulling, and drug feather removal, but also does not affect reproduction and rejuvenation.

Description

technical field [0001] The invention relates to a method for collecting goose feathers through artificial nutritional intervention. Background technique [0002] Goose feathers, especially down, are high-quality thermal insulation materials with high economic value. In order to obtain the feathers of geese, the method of slaughtering and scalding, live plucking or drug depilation is usually used for collection. In the slaughtering and scalding method, the feathers of geese can only be collected once in a lifetime. The protein properties and elasticity of the feathers scalded by high temperature and humidity will change to a certain extent, and the down feathers, flake feathers and wing feathers for different purposes cannot be collected separately. In live plucking, the feathers are manually plucked, resulting in pain in the goose body, damage to the hair follicles, damage to the skin, severe anal prolapse, and a reduction in the output of new feathers. Drug depilation, in...
