Second, living plucking is a new hair removal method that has emerged in recent years. The advantage is to obtain high quality down and increase down production. Most of the goose's opening months are late, or they are used to postponing the geese's egg laying months to 7 months of age, and some are delayed to 9 to 10 months of age. If live pull hairs begin at 75 days of age, at least 40 hair blisters (75 days, 117 days, 160 days or so) can be removed at least for each of the 40 days prior to opening. The geese can be matured at 6 weeks of age. If the goose body starts to plucking after being matured, each geese can pull 4 times before opening (approx. 45 days, 87 days, 120 days, 162 days). ). Such as an average of 120g live plucking each time, three plucking can get 360g down.
Third, when the goose body live plucking, there will be different degrees of stimulation such as broken skin bleeding, so that the goose body is subject to certain damage, at least a slight phenomenon of pore bleeding. Therefore, attention should be paid to the following aspects when live pulling hairs:
1, frail malnutrition or sick goose can not live pull hair, should be picked out without pulling hair. Such goose feathers are not good to pull but also affect the health of the goose body.
2. After the goose is plucked, it does not allow the goose to bathe to prevent wound infection, slow healing, and affect the health of the goose. According to the skin wound conditions can decide when it can be launched. It is generally within 4 to 7 days after the live plucked goose is not bathed. In addition, it is necessary to keep the inner litter (grass) clean, and there should be a pergola in the summer sports field to prevent the goose body from being affected by rain and direct sunlight.
3. If the appetite is poor within 3 to 4 days after the plucking of the goose, it is a normal phenomenon and there is no need to worry. Mainly because the live plucking hair stimulates the goose's skin to make the goose nervous and cause the body temperature to rise. It is only necessary to strengthen the feeding and management.
4, such as improper hair pulling process in Baoding or goose tension caused by anal excretion, use 2% potassium permanganate solution to wash off the prolapse of the anal area, back a few days like.
5, goose live plucking temperature requirements: as long as the temperature outside the home is not less than -15 °C, you can go live plucking. However, geese should be kept in the house for 2 to 3 days after plucking. The use of the goose growth stage and the moulting period to stop moulting will not affect the growth and development of the geese and laying performance. It will also prevent the fly feathers from flying off due to natural moulting and affect the environmental hygiene. Increase down production, reduce the breeding costs of breeding geese, and increase the economic benefits of geese.
Goose Down Collection and Attention Problems
First, the carcass is taken after the slaughter goose feather down once, all charged, and divided into: hot water, steaming and dry pulling three kinds of acquisition methods. Water scalding method is also called scalding method and scalding method. After the geese slaughtered, they collected the goose blood and tried to drain the blood of the goose as much as possible to ensure the quality of the goose's body and internal organs. The body had no blood, the body surface was white and beautiful, and the meat quality was good. It is advisable to remove the big scorpions on the wings (swift, knife, and socket) and store them separately before scalding. Otherwise, it will be mixed into the feathers, which will affect the down quality and will be wasted as waste. After slaughtering, use hot water of about 68°C to scald all hairs and collect all down. The steaming method is about to slaughter the goose body after draining the blood and place it on the steamer. Steaming for 1 to 2 minutes after the hair removal is a method adopted by people in recent years to improve the utilization value of down. According to the classification and use of down structure to collect down, you can first pull the big feathers of the two wings, then pull the body hair, and finally pull the feather. Then use hot water to remove the body's hair and excess feathers. When steaming, the goose body is placed flat in the steamer and cannot be placed on the side of the pan. The steam temperature and time must also be known. When the steamer is steamed for 1 minute or so, open the lid of the steamer and turn the goose body upside down and try on the big wings. Pull it out and pull it out, otherwise steam it again. Dry extraction is a way to increase down value. When there is still warmth in the goose after slaughter, the method of lively pulling out the feathers is used to separate and store the feather structure according to the classification and use. Then use water to remove the remaining feathers.
