Application of Chinese Herbal Medicine in Moulting Moulting of Chickens and Ducks

Since 1995, according to the needs of poultry production, the author has arbitrarily added Radix Isatidis, Reed Root, Alfalfa, Peppermint, Dandelion, Chine and other Chinese herbal medicines in the “Wu Cao Yin” as appropriate. After cooling, it can be used as a drinking agent or drug to dry crushed. , As a feed additive, after a trial of forced moulting chickens and ducks, there is a significant promotion of feather growth, consolidation of the evil, disease resistance and rousing effect.

1 prescription and usage?

1.1 prescription drug composition?

Motherwort 500 g, Houttuynia cordata 250 g, Gardenia grass 500 g, Shamrock 500 g, Plantain 250 g. After the medicine is decocted with water and cooled, it is served for 500 to 800 chickens and ducks within 1 day. In winter and spring, appropriate amount of Banlangen, reed rhizome, Artemisia leaves, switchgrass, etc. can be added; in the summer and autumn, Houttuynia cordata, clover, chrysanthemum, dandelion, wild land, alfalfa, etc. can be reused; when used for cuddling, Mint and habitat can be added flexibly. , borneol and other appropriate amount, pay attention to reuse Motherwort, peppermint, and use liquid medicine to drink with bath as well. ?

1.2 method?

Firstly eliminate the sick, low-yield, over-fat and over-skinned individuals, close the forced moulting chickens (duck), stop the water and fast according to conventional methods, and stop artificial light supplements (eg, the birds stop for 48 hours, fasting 72 h, 8 hours of light per day). At 48 h and 60 h, 100-150 ml of “Wujicao” was given, and after 72 hours, crude feed supplemented with 25% ZnSO4 was fed, and for the first time, half-fullness was used as the degree. Increase the amount of free drinking Wucao drink 7 days or feed added Wucao Yin feed 7 to 10 days; 10 days after the return of normal layer chicken feed, and daily increase in light (daily increase 30min, until daylight 17h only); At the same time, weekly supplemented with 0 1% potassium permanganate solution sterilized sand 1 to 2 times to restore free drinking water. ?

2 Application?

2.1 When the chicken (duck) group laying rate is less than 50% to 60% or about 10% of the chickens (duck) begin to moult, and the group of chickens (duck) is ready for retention, compulsory moulting should be considered. .

2.2 Some diseases are endemic in the local area and chicken (duck) breeding will take risks or difficulties. When groups need to be replaced, compulsory moulting may be carried out. ?

2.3 If the chicken (duck) group causes a sudden drop in the egg production of the group due to some reasons (such as feed replacement, illness, lack of light or regularity, various stresses, etc.) and cannot recover in a few days, the forced change can be considered. feather. ?

2.4 Based on local market conditions and poultry status, artificial forced moulting may also be considered when facing or anticipating a recent oversupply of eggs. ?

3 Application effect?

Example 1 In the Shenqiu County Bureau of Animal Husbandry, 4,500 chickens in three batches were forced to moult by the above methods. Generally, the hens began to lay eggs again about 3 weeks after the water stopped and fasted; eggs were laid at 4 to 5 weeks. Rate of 10% to 25%; 7 to 8 weeks egg production rate of 55% to 65%; 10 to 12 weeks egg production rate of 70% to 80%; 15 weeks, up to 85%. This method increases the egg production rate by 5% to 10% over the single hunger, water cut, and chemical methods. ?

Example 2 The drinking water of Wucao drinking at a duck farm in Guangshan County was 5 to 7 days. The bathing pool was used to feed 2800 ducks for artificial moulting. The ducklings had 4 to 5 natural moults during the whole moulting period. The month is shortened to 45-55 days. Four to five weeks after plucking, the duck begins to lay eggs. The overall production capacity reaches 86% of the first egg-laying year and lasts more than 10 months. ?

4 Cautions?

4.1 When formulating a forced moulting plan for chickens and ducks, one should first manually select chickens (duck) that are robust, disease-free, have good production performance, and have good body development. ?

4.2 Ten to fifteen days before compulsory moulting begins, immunizations are given and insects and lice are removed to ensure that chickens (duck) only adapt to the stimuli caused by forced moulting and the health of the next laying period.

4.3 When the chicken (duck) group is in a state of high hunger and stress, adaptability and digestive function are reduced. Therefore, when feeding is resumed after the forced moulting begins, care should be taken to reduce the number of times. , Evenly supply, to ensure that the chicken (duck) digestive system gradually adapt to feed replacement and liquid stimulation, to avoid intoxication due to hyperphagia and cause indigestion or death. ?

4.4 In the summer, chickens (duck) are forced to moult only. Care must be taken to ensure that the liquid is fresh and ready for use. It should not be overnight, and ventilation and shade should be strengthened to prevent heat stroke. In winter, forced moulting should be used. Increase energy feed, pay attention to cold insulation. ?

4.5 During forced moulting, the body weight of chickens (duck) will be significantly reduced, physical fitness will be weakened, and disease resistance will be reduced. At this time, we must steadily protect the safety of chickens and ducks. In addition to paying attention to keeping the pens clean and dry, the temperature should be appropriate, and we must also pay attention to drinking Chinese herbal medicine Banlangen, dandelion, leaves, mint, etc., and increase Motherwort. The amount of clover is used to increase its ability to support evils and eliminate pathogenic and anti-drug, and to reduce the death of chickens and ducks caused only by stress. ?

4.6 In order to ensure the effect of forced moulting, trace elements (iron, selenium, zinc, etc.) should be added to the diet, and the amount added should be 1 to 2 times the normal standard for 5 to 7 days; at the same time, attention should be paid to calcium. Quality and multivitamin supplements. Through the above comprehensive protective measures, the mortality rate of chicken (duck) group can be controlled within 3%. ?

4.7 Cooping chickens for forced moulting also requires attention to the issue of birds being coops. The main prevention measures are darkened chicken coops and reduced light hours. After the chickens are basically returned to normal, the black shading device is removed, normal lighting is restored, and normal feeding and management is performed. ?

4.8 For forced moulting of ducks, care should be taken to remove large and small feathers at the same time in order to shorten the entire moulting period. ?

4.8.1 The main wing feathers, aileron feathers, and tail wings of ducks are generally pulled out by hand. However, it is necessary to pay attention to grasp the appropriate time for artificial pullout. If it is too early or too late, it will affect the health of ducks and the growth of new feathers. ?

4.8.2 Generally, about three weeks after stopping the water, observe the "hulling" of the upper wing of the duck wing.

At this time, the nutrients stored in the duck's body are consumed by forced moulting, and the muscles in the body and both wings also become thinner and “shrink”; When the root of the airfoil is seen, a light colored tube root of about 3 to 4 mm in length appears. Traces, and when dry or contracted (ie, "shelling out"), this is the best time to pull the plume.

4.8.3 It is best to pull the plume manually. In the morning on a sunny day, the concentrating staff should quickly and unilaterally pull all the unpeeled wing feathers and tail feathers one by one in the direction of the tip of the feather (don't greet one more time, otherwise, it will easily damage the skin. , resulting in wounds or broken wings), after the big feathers are pulled out, the ducks can only be put into the Chinese herbal bath water, bathing, and strengthen the feeding and management to ensure the effect of forced moulting.
