Egg Brother’s purpose: focus on laying hen breeding, and strive to share the technical experience of high-yield chicken raising in the most simple language, help laying hen farmers and solve substantial problems.
Raising chickens will inevitably encounter chicken diseases. Using medicine in chickens is not a very simple thing, because there are many types of veterinary drugs, and chemical reactions may occur when mixed with different veterinary drugs, thereby increasing or decreasing the efficacy of the drug. In front-line chicken farms, chicken farmers often encounter chickens who use various medicines to treat chickens in order to treat them, and they wish they could use all the medicines that can cure the disease. They do not know what the consequences will be. This kind of casual use of medicine is irresponsible to the chickens you raise, and even more so to yourself.
To effectively treat diseases, you need to choose sensitive drugs, appropriate dosing methods, clear the coordination between drugs and antagonism of and medication attention, so as to achieve twice the result with half the effort.
. Methods of administration
. Drinking water administration
Drinking water administration is the most convenient and common method of administration, and is suitable for highly water-soluble drugs, that is, the drug should be easily soluble in water. In addition, drugs such as penicillin that have poor stability in water should be used and prepared immediately, and the dosing time should be controlled within 6 hours. In addition, for short-term or emergency use drugs such as live seedlings, water should be stopped for 2-3 hours before dispensing to ensure that every chicken can drink the medicine.
. Mixed feed dosage
Mixed feed dosage is one of the common drug dosage methods. Most of the mixed feed drugs are powders or liquids that are insoluble in water or have poor palatability, and are suitable for large groups of chicken farms. It should be noted that when mixing the feed, take a small amount of feed first, mix thoroughly, and then gradually mix the feed into all feed. When sick chickens do not eat ingredients or eat very little, it is not advisable to use mixing ingredients to give medication.
, Injection and administration
Injection and administration are mainly used for injection of antibiotic injections and oil seedlings. The advantage of this method is that the liquid is absorbed quickly and the dosage is high, but the operation is troublesome and the workload is large.
, aerosol administration
aerosol administration is administered through the respiratory tract of chickens, mainly used to prevent and treat respiratory diseases and aerosol immunity of live seedlings. This method absorbs quickly and acts quickly. It is a drug delivery method that can both act locally and absorb through the lungs, and has little stimulation to the respiratory tract.
. Drilling and administering
Oral administration is mostly used for chickens with more accurate dosage requirements. It is better for farmers with small breeding numbers to use this method.
2. Drugs for common bacterial diseases
. Drugs with better effect from chicken E. coliosis
: ① Gentamicin sulfate injection, calculated based on 3,000-5,000 units per kilogram of body weight, intramuscular injection, twice a day, for 3 consecutive days. ② Kanamycin sulfate injection, calculated at 1,500 units per kilogram of body weight, intramuscular injection, twice a day, for 3 consecutive days. ③ Add fluphenolate (norfloxacin) to water at a dose of 0.1%, and drink it for 3-5 days.
, Chicken Salmonella disease
Chicken White Diassodium and Avian Typhoid: ① Use sulfadimethacil and sulfonamide synergist (TMP), the ratio of TMP to sulfonamide is 1:5, mixed in feed, and the concentration is 0.02%; ② Add 200-500 mg oleracin to each kilogram of feed, which also has a certain effect on Salmonella dysentery and Salmonella typhoid. Avian paratyphoid: ① Gentamicin; ② Sulfare dimethicone.
, chicken infectious rhinitis
sulfonamides and oleracillin can inhibit and kill Haemophilus parachycin. ① Use sulfadimethacil and sulfonamide synergist (TMP). The ratio of TMP to sulfonamide is 1:5, mixed in feed, and the concentration is 0.02%. Use one course of treatment (5 days) and use another course of treatment one week apart to have a certain course of treatment for rhinitis. ②Secondly, oleracycin can also be fed with 0.1% mixture and used continuously for 3-5 days.
, Mycoplasma chew poison disease-slow-resuspension
Drugs have better effects: ① tylosin , tylosin , doxycycline, ② followed by rigomycin, grandimycin, lincomycin , oleracycin, ③ streptomycin and gentamicin also have certain therapeutic effects.The above drugs are put into water at a ratio of 500mg/L and drink them for 5 consecutive days, which will help treat and relieve the condition.
, Mycoplasma synovitis disease
drugs with better effect: tylosin, tylosin, rigomycin, doxycycline, grandimycin and quinolones drugs. During treatment, adding rigomycin, tylomycin (250-500mg/L) or enrofloxacin and ofloxacin (250-500mg/L) to drinking water for 1-2 consecutive courses (one course of 5 days) to control and relieve symptoms. However, due to long-term use of drug treatment, some strains may become resistant to streptomycin, gentamicin, tyloxin and quinolones. It is best to conduct drug sensitivity tests in the onset chicken farms and choose the most sensitive drugs.
6, Avian cholera-pasteurosis
Drugs with good effect: ① Otachomycin is fed with 0.1% mixture and used continuously for 3-5 days; ② 0.005% cefotaxime drink water for 3-4 days; ③ The population is small, penicillin and streptomycin are intramuscularly, 50,000 to 10,000 units per person, once a day, for 3 consecutive days. ④Sulfadimethacil and sulfonamide synergist (TMP) were used in combination. The ratio of TMP to sulfonamide is 1:5, mixed in feed, and the concentration is 0.02%. ⑤ Quinolones such as 0.008%-0.01% ciprofloxacin or ofloxacin, use them for 3-5 days and have good results.
3. Contraindications for combination medication and compatibility
, ampicillin , amoxicillin ,
① Can be combined with streptomycin, neomycin, polymyxin, quinolones, etc., and the efficacy is enhanced; ② Be cautious with timikacin , roh erythromycin , doxycycline hydrochloride, foxonico , and the efficacy is reduced. ③It cannot be combined with VC, erythromycin, and sulfonamides, otherwise it will be antagonistic and ineffective.
, Lincomycin hydrochloride
① can be combined with metronidazole, and the efficacy is enhanced; ②Sheng and rosomycin and temicocin will be combined with reduced efficacy. ③ It cannot be compatible with sulfonamides and antagonistic failure.
, neomycin sulfate, gentamicin
① can be combined with ampicillin, cefaladin, cefalexin, doxycycline hydrochloride, TMP, etc., and the efficacy is enhanced. ② Be careful to cooperate with Vc and foxoneco, and the efficacy will be weakened; ③ If it cannot be combined with similar drugs, the toxicity will increase.
, erythromycin, timicocin
① Can be combined with neomycin, gentamicin, frefenicol, etc., and the efficacy is enhanced; ② Be cautious with streptomycin and lincomycin hydrochloride, and the efficacy is reduced. ③It cannot be compatible with kanamycin and sulfonamides, and the toxicity is increased. ④ If it cannot be combined with sodium chloride and calcium chloride, it will precipitate and fail.
, Otachomycin, doxycycline
① can be compatible with similar drugs and TMP, and the efficacy is enhanced. ② If it cannot be combined with trivalent iron and trivalent chloride ions, it will form insoluble complexes.
6, frefenicol
① can be combined with neomycin, doxycycline hydrochloride, colistococcus sulfate, etc., and the efficacy is enhanced. ② Be cautious with ampicillin, cefaladin, cefalexin, etc., and the efficacy is reduced. ③ It cannot be compatible with kanamycin, streptomycin, sulfonamide, quinolones, and VB12, and the toxicity is increased.
7, norfloxacin, enrofloxacin, ciprofloxacin
① Can be combined with ampicillin, cefaladin, cefalexin, streptomycin, neomycin, gentamicin, sulfonamide, etc., and the efficacy is enhanced. ② Be cautious in combining with tetracycline , doxycycline hydrochloride, rosomycin, frefenicol, etc., and the efficacy is reduced.
8, sulfonamide
① can be combined with TMP, neomycin, gentamicin, and kanamycin, and its efficacy is enhanced. ② Safe to combine with ampicillin, cefalexin and cefaladin, and the efficacy is reduced. ③It cannot be combined with rosomycin and frefenicol, and the toxicity is increased.
4. Pay attention to the medication
1. When administering sulfonamide drugs, the first dose should be doubled. One dose should not exceed 5 days. Add sodium bicarbonate at the same time to reduce acetylated sulfonamide crystals and reduce kidney damage. When administering
2, tetracycline and iron drugs, stop feeding calcium-containing feed such as stone powder, bone powder, shell powder, egg shell powder, etc.
3. Sulfur-containing drugs such as calcium sulfate, sodium sulfate, and artificial salts cannot be used with sulfonamide drugs.
4. In most cases, acidic drugs cannot be used in combination with alkaline drugs. Acid drugs include sulfonamides and penicillin, while alkaline drugs include erythromycin, streptomycin, gentamicin, neomycin, tetracycline, and lincomycin. However, sulfonamides and penicillin have better efficacy in alkaline environments, while erythromycin and tetracycline have better efficacy in weak acid environments (pH 6-7).
5. The sodium chloride in the feed cannot exceed 0.5%, otherwise it will easily cause adverse reactions; if the chicks drink 0.9% saline, 100% of the chicks will die within 5 days.
6. Antibiotics and sulfonamide drugs are prohibited during the injection of antibacterial vaccines and the production of sufficient antibodies has not yet been produced; disinfectants and antiviral drugs are prohibited 3 days before and after the live vaccine are vaccinated.
5. Misconceptions about medication
1. Do not understand the causes, symptoms, and types of chickens to use medication blindly. The premise for the rational application of any drug is correct diagnosis. If you do not understand the disease process and use the drug blindly, it will not only not achieve results, but will delay treatment and aggravate the development of the disease.
2. Long-term use of the same drug for chickens will cause drug resistance and the drug will not work for the disease.
3. Once the chickens become ill, they do not use according to the instructions of the drug and increase the dose at will, which will increase the burden on the liver and kidneys, which is not conducive to the recovery of the disease.
4. The state uses veterinary drugs without authorization during the egg laying period, causing the drug-free eggs to flow into the market. Once discovered, they will be punished more severely.
In short, in the process of using chicken diseases, it is necessary to choose appropriate dosing methods based on the nature of the drug itself. For complex chicken diseases, use the drug in combination and synergistically to give full play to the efficacy of the drug, so as to achieve twice the result with half the effort.
