Cattle of all ages can suffer from this disease, but calves and pastured cattle are most common. The disease occurs mainly from May to June and reaches its peak from August to September. When the disease first appears, the affected eye is photosensitive, watery, the eyelids are swollen, the pupils are dilated and the conjunctiva is congested and swollen. After symptoms worsen, mucopurulent discharge will drain from the eyes and the corneas will become cloudy, affecting vision. In the later stage, secondary keratitis, iritis, cataracts, upper and lower eyelids cannot close, eye itching and restlessness, frequent head shaking and finally corneal ulcers or perforations, lesions lens and blindness in one or both eyes.
Treatment Methods
(1) Surgical Therapy: The fundamental method for treatmentTreating the eye worm involves using an eyelid dilator to open the conjunctiva and using tweezers to remove the worms. The method is as follows: baoding the sick cow, fixing the head and instilling the eyes with 2% procaine hydrochloride solution. The surgeon uses his left hand to open the eyelid, fix the eyeball and remove parasites from the conjunctival sac.
(2) Oral administration of levamisole phosphate. 7 to 9 mg per kilogram of body weight, taken for 2 days.
(3) Wash your eyes with 0.05% iodine water or 2% to 3% boric acid water. At the same time, insert a cotton ball into the corner of the eye socket and carefully wipe the worms. .
(4) Use 0.002% Haiqunsheng or 0.5% Lysol to vigorously rinse the conjunctival sac to kill or remove parasites.
(5) Drop 2% cocaine in the eyes. Once the worms are stimulated, they will crawlt from the corner of the eyes, then use tweezers to remove the worms.
(6) Use distilled water to prepare a 0.5% to 1% solution of levamisole hydrochloride and instill 3 to 5 drops into each eye each time, once in the morning and once in the evening. When the disease is severe, symptomatic treatment is necessary, but mercury should not be used to prevent permanent blindness.
(7) Soak 120 grams of dried tobacco leaves in 500 ml of lukewarm water at 60°C for 12 hours, then filter with 4 layers of gauze, rinse your eyes with the filtered liquid, rinse once a day, and you will be cured after 4 times.
(8) 35 grams of rhizome root and 35 grams of neem bark, decoction in water and wash the affected eyes with the decoction. Use 2 to 3 times a day for 3 days.
(9) Mix 1 part leek juice and 1 part vegetable oil and drop it in the eyes to kill thes insects or chase them away from your eyes.
(10) Dissolve an appropriate amount of table salt with warm water and prepare 1% to 3% saline solution. Spray it into the affected eye once a day, morning and evening, for 3 to 5 consecutive days. .

As the saying goes: “If dog meat rolls three times, the gods will not be able to sit still.” This shows the delicious taste of dog meat and the huge market demand. In this way, accelerating the weight gain of meat dogs means that more economic benefits can be obtained. Here are two effective ways to fatten meat dogs for farmers' reference.
1. Hypnotic fattening
So-called hypnotic fattening consists of using drugs to anesthetize and hypnotize meat dogs, so that they can eat andsleep as needed, and eat as needed. they wake up, allowing them to consume their physical energy. Keep it to a minimum to achieve the goal of rapid weight gain. The specific methods are as follows:
1. Depending on the size of meat dogs, mix 1-3 grams of Datura flowers into the diet at each meal, and anesthetize and hypnotize the dogs (Datura flowers mentioned here are not just that). is just the flower, but a mixture including Datura seeds, flowers, leaves, hulls, etc. which are dried and ground into powder). When feeding, it is best to knead a little sweet potato or cooked taro into a cake shape and wrap the medicinal powder, then feed it according to the dosage of each meat dog, and then feed it. other foods. If you add a small amount of sleeping pills to datura flowers, the anesthetic and hypnotic effect will be more stawheat. Each meat dog can receive 1-3 sleeping pills per meal depending on their size. At this time, the dosage of datura flower powder can be reduced by half and mixed. Generally, sleeping pills with better effects include cocobarbital and nebitol, followed by luminal diazepam tablets. You can use one of the above sleeping pills at a time.
2. Prevent and treat diseases. If the meat dog vomits after eating, you can take 10 grams each of pinellia, ginger, poria, tangerine peel, Shenqu and cloves, boil them in water to get the juice, add broth or bone soup and give it orally though; the meat dog suffers from food poisoning, you can use a preparation of 10 grams each of Pinellia ternata, Poria cocos, tangerine peel, Atractylodes, malt, Shenqu, Magnolia officinalis, Fructus aurantium and Acosta add an appropriate amounteed of honey and boil in water for oral administration; if a slaughter dog suffers from mange, 20 grams of sulfur can be used, and a piece of snake molt can be used to burn it, turn it into charcoal, grind it and mix it with rice (ingredient) and feed him. once ; for dog flies, you can use raw sesame oil or raw tea oil and apply it on the dog's body hair to get rid of them effectively.
3. Feed high-quality food to meat dogs regularly and quantitatively, such as rice, bone soup porridge, corn meal or soybean meal mixed with rice bran, wheat bran ( should be cooked and fed), etc., and add a small amount appropriately to promote growth. At the same time, positioning training should be carried out to enable meat dogs to develop thehabit of positioning the excretion.
In addition, the following prescriptions can be used for hypnotic drugs for meat dogs: Recipe 1: 500 grams each of datura and buddleia flowers (dry products), mix and grind into powder, one for each small meat. dog at a time Feed 1 gram, large meat dogs feed 1.5 grams, feed 3 times a day, mix the medicine evenly into the food, and let the meat dogs eat freely. Recipe 2: Take equal amounts of raw Chuanwu, raw Caowu, Yibululu and Zuixiantao and grind them together into powder. The dosage and method are the same as above. Recipe 3: Use chlorpromazine hydrochloride tablets, according to the dosage of 8-10 tablets for a 5 kg meat dog, feed it once, then feed it again every 1-2 days.
2. Castration and fattening
Just like a rooster whobecomes a capon and quickly gains weight after castration, the male dog becomes docile after castration, its growth accelerates and its weight gain is particularly obvious. Therefore, male dogs not used for breeding may be neutered and fattened at 2 months of age, which can result in significant fattening effects. Neutering generally uses the following three methods:
1. Use your left hand to press the testicle from the inguinal canal into the scrotum, pinch and fix it with your index finger and thumb, disinfect the incision with iodine, and then use a sterilized castration blade to cut the skin about 1 cm in the vertical direction of the testicle, wring out the testicle and twist. Cut the spermatic cord and disinfect it with iodine to stop the bleeding. There is no need to suture the incision, just let it heal on its own.
2. Ligation method. UseFirst use iodine to disinfect the skin of the scrotum, then pinch the testicles with two fingers of your left hand and tie the two testicles with the scrotum with a rubber band. Soon, the testicles will detach spontaneously. After shrinking, the male dog becomes docile, his appetite increases day by day and his weight gain accelerates.
3. Chemical method. First dissolve 10 grams of sodium chloride in 100 ml of distilled water, add 1 ml of formaldehyde solution, shake well, filter and bottle for further use. Once the male dog is stabilized, use iodine to disinfect the front of the long axis of the scrotum. Depending on the size of the dog, inject 2 to 3 ml of medicinal solution into each testicle to carry out castration.

Personally, I thinke that camel batteries are better.
Some issues that need to be paid attention to when using and maintaining batteries:
1. If the battery is not used for a long time, it will discharge slowly until it is discarded. Therefore, the car must be started at regular intervals to charge the battery. Another way is to disconnect both electrodes from the battery. It is important to disconnect the positive and negative electrode wires from the electrode terminals. You must first disconnect the negative electrode wire or remove the connection between the negative electrode and the car chassis.
Then unplug the other end with the positive (+) mark. The battery has a certain lifespan and must be replaced after a certain time. The above order should also be followed when replacing, but when connecting the electrode wire,the order is exactly the opposite, connect the positive electrode first, then connect the negative electrode.
2. When the ammeter pointer indicates that the battery capacity is insufficient, charge it in time. The battery charge level can be reflected on the dashboard. Sometimes you find that the battery is insufficient on the road and the engine stalls and cannot start. As a temporary measure, you can ask other vehicles for help and use their vehicles' batteries to start the vehicle. two batteries to the negative terminals and the positive terminals to the positive terminals.
3. The density of the electrolyte should be adjusted accordingly according to the standards of different regions and seasons.
4. When the electrolyte is depleted, distilled water or a special rehydration solution should be added. Do not use purified drinking water instead. Pure water containing various trace elements,it will have harmful effects on the batteries.
5. When starting a car, continued use of the starter can damage the battery due to over-discharge. The correct way to use it is to start the car each time for no more than 5 seconds, and the interval between restarts is not less than 15 seconds. If the car still does not start after several starts, the cause must be looked for in other aspects such as the circuit, ignition coil or oil circuit.
6. During daily driving, you should always check whether the small hole on the battery cover is ventilated. If the small hole in the battery cover is blocked, the hydrogen and oxygen generated cannot be discharged. When the electrolyte expands, it will cause the battery shell to burst and affect its service life.
7. Check the positive and negative stages of the battery for signs ofoxidation. You can frequently pour hot water over the battery wire connections, clean them with a copper wire brush, and apply butter.
8. Check for aging or short circuits in different parts of the circuit. Prevents the battery from prematurely discharging due to over-discharge.
9. It is prohibited to store the battery in case of power loss. If it is exhausted and left unused for a few days, recharge it., the plate is prone to sulfation and the capacity decreases.
10. Regular inspection: Measure the voltage of a single battery regularly if the voltage of one battery is lower than 10.5V, you need to go to a service station for inspection or repair to avoid damage to the other two batteries in good condition.
11. The designed load capacity of electric bikes is 75 kg. Avoid carrying overweight items. VeuilUse pedals to help you when starting and going uphill.
12. In winter, battery capacity decreases as the temperature decreases. This is a normal phenomenon, taking 20℃ as the standard, the capacity is generally 80% at -10℃.
13. Keep the battery surface clean for a long time. Do not expose the vehicle to direct sunlight when storing it. Park the vehicle in a cool, ventilated and dry place.
14. When the battery is to be left for a long time, it must first be fully charged and is usually replenished once a month.
15． Use the pedals to assist the vehicle when starting, going uphill, overloading or facing into wind to avoid significant current discharge.
16. When charging, use a special charger and place it in a cool, ventilated place away from high temperatures and humidity.
17. Do not use solvents oorganic to clean the battery case.
18. Do not short-circuit the positive and negative terminals of the battery to avoid danger.
19. Over-discharging is prohibited: When the red undervoltage indicator light on the dashboard lights up, it indicates that the battery has entered the starvation zone and needs to be charged in time.
20. Overcharging is prohibited: The recharge time must be different depending on the mileage, the longer the mileage, the longer the recharge time, and vice versa.
21. If the battery fails, please send it to the manufacturer's authorized office or relevant organization for proper handling. Please do not throw it away randomly to avoid environmental pollution.
