The feather picking of duck causes a large amount of food consumptions owing to consuming compared with large energy, gives to produce and brings loss. The feather picking main manifestations of duck the feather of mutually pecking at, once occur, spread very soon, severe patient anus feather, tail feathers, back of the body plumage are all pecked light, and wing skin is exposed, further will cause and peck skin, peck meat, peck anus, the lighter causes carcass quality to decline, and severe one causes is caused injury by picker or lethal, and some is individual because gulp down into a large amount of feathers simultaneously, cause alimentary canal to stop up and death, directly affected the overall efficiency of foster duck industry.

The reason that causes duck feather picking is a lot, mainly causes because feeding and management is improper, as hypomotility, colony house improper ventilation, light is excessively strong, and feed is single, in potein deficiency or feed, lack sulfur-containing amino acid, or do not mend salt because feed is medium-term and long-term, fixing grade of feeding time and cause and peck addiction. Duck feather picking comparison the underlying cause is also often considered to due to the mineral element shortage and high-density rearing in feed, thereby conventional processing method is supplement the mineral element lacking and reduce stocking density in feed, some methods by land plaster treatment duck feather picking addiction are provided as announced in " Chinese animal doctor's science and technology " 03 phase in 1988 by the article of " the land plaster treatment duck feather picking addiction " of appointing an outstanding literary figure to deliver; In " Fujian animal and veterinary " supplementary issue in 2007, also announce in the article of " control of kind duck feather picking addiction " delivered by Wu Bixia and adopted balanced nutrients, added gravel, improved the methods such as environment and prevent a kind duck feather picking phenomenon.

Chinese patent literature application number is 201310465227.9 in addition, publication No. is to disclose a kind of mixed feed that prevents meat duck feather picking in the data of CN103583861A, this feed is obtained by the raw material proportioning of following percentage by weight: corn 60-80, dregs of beans 20-30, rice bran 15-25, peanut meal 12-15, barley 8-10, rice straw 15-18, green bristlegrass seed 5-6, black bean powder 4-5, cypress seed powder 3-4, oyster shell whiting 1-2, meat meal tankage 1-2, hydrolyzed feather meal 0.5-1, sunflower seed powder 2-3, skin of soya-bean milk 4-5, seawood meal 2-3, fish rice noodle roll 2-3, calcium monohydrogen phosphate 1-2, peanut seedling 4-5, beet tops 3-4, finelydivided phtheirospermum root 2-3, salt is appropriate, phagostimulant 0.2-0.5. the method that this technical scheme has been improved nutrition by sufficient mineral composition is provided, has effectively avoided meat duck to occur the phenomenon of feather picking, has ensured that it grows normally.

These are all some trials and innovation that the art is carried out on prevention and treatment duck feather picking above. These methods can reach the effect that reduces duck feather picking, find out on the basis that reason carries out again, and in practical application, effect are also desirable not enough but must be based upon.

Summary of the invention

The object of the present invention is to provide a kind of method of eliminating egg duck feather picking, to overcome the technical problem that is also difficult to effectively eliminate duck class feather picking phenomenon in prior art.

Technical scheme of the present invention is such: basic thinking is sprayed a kind of solution on duck group feather, contains and make animal produce the chemicals of feeling sick and feeling in the composition of this solution; In this chemicals, contain quinine. This solution is preferably quinine sulfate solution. This quinine sulfate solution is prepared as follows: get one of quinine sulfate powder or quinine sulfate, quinine sulfuric ester dihydrate, quinine sulfate dihydrate by mass fraction, with after appropriate distilled water dilution, add 70% sulfuric acid solution, fully stir and make its dissolving formulated. Quinine sulfate solution is 2%～4% by the concentration of mass fraction preparation, and preferred compound concentration is 4%.

On duck group feather, before spray solution, with plastic sheeting, egg duck head is wrapped up, spray number of times and be at least twice, spray according to 0.125mL/ sprinkling amount only for the first time, then make its feather be dried 5min; Spray according to 0.5mL/ sprinkling amount only for the second time. Observe duck feather picking situation only. Feather picking serious duck group spray according to 1mL/ concentration, after feather is dry, removes head plastic sheeting. Within 4 weeks before the egg-laying peak of egg duck, spray continuously, spray every day 1 time. Because quinine is containing virose alkaloid, after sprinkling, should note observing duck health status only, according to the order of severity control sprinkling amount of feather picking.

In addition, also can spray garlic extract and substitute quinine sulfuric acid solution, or the two is in conjunction with alternately spraying, wherein the compound method of garlic extract is such: get that fresh garlic is removed the peel, cleans, dried, after low temperature sterilization, be broken into mud 1min with tissue mashing machine, enzymolysis 30min, add phosphate buffer lixiviate 30min in 35 DEG C of waters bath with thermostatic control, and carry out centrifugal treating 25min according to the rotating speed of 3000r/min, get supernatant vacuum filtration twice, make 1g/mL garlic extract, be loaded in test tube, put in-20 DEG C of refrigerators stand-by; When use, add sterile distilled water and be diluted to 1% garlic extraction solution.
