Research Progress on Detection Technologies for Porcine Circovirus
Porcine circovirus disease is a class of viral infectious diseases caused by porcine circovirus (PCV) infection and characterized by immunosuppression, with the main clinical manifestation being postweaning multisystemic wasting syndrome in piglets caused by PCV-2. This article reviews the research progress in recent years, both domestically and internationally, on detection technologies for this virus, including virus isolation, electron microscopy, polymerase chain reaction, indirect immunofluorescence assay, immunohistochemistry, enzyme-linked immunosorbent assay, and in situ nucleic acid hybridization.

How to Use the DRAMINSKI Pig Pregnancy Detector and Its Features
The DRAMINSKI Pig Pregnancy Detector is a portable, relatively high-performance ultrasonic testing instrument that can identify whether an animal is pregnant with maximum accuracy. This allows pregnant animals (sows and ewes) to be selected in a timely manner, reducing labor and feeding costs. The detector measures the amniotic fluid in the uterus to determine whether the female animal is pregnant. The test can be easily completed simply by pressing the ultrasonic probe against the animal's skin. Once pregnancy is detected, the indicator light flashes rapidly and a high-frequency sound signal is emitted. Operation can be completed with just one button press.

How to observe sick pigs? Master these methods to detect pig diseases early
Check the demeanor. Healthy pigs are spirited, with tails raised and swinging freely; sick pigs are listless, move slowly, prefer to lie still, and have drooping tails. Check the appetite. Healthy pigs have a strong appetite; sick pigs show a sudden loss of appetite, abnormal eating habits, or even stop eating. If a pig's appetite decreases and it drinks a lot of water, it is mostly a febrile disease. Check nasal discharge. Healthy pigs have no nasal discharge; if a pig has clear nasal discharge, it is mostly a wind-cold cold, thick and sticky nasal discharge indicates heat in the lungs, and nasal discharge containing foam indicates diseases such as pulmonary edema or chronic bronchitis. Check the feces. Heal

How to detect suspicious sick rabbits early? A must-read for rabbit keepers
Examine the ear color of a healthy rabbit: pink, with bright eyes. If the ears are red or light purple, it means the rabbit is overheated; placing it in a ventilated hutch to rest a while will relieve it. If the ears are pale and feel cool to the touch, it means the rabbit has drunk too much cold water or has caught a chill; on auscultation there will be a sloshing sound in the abdominal cavity, and placing the sick rabbit on a heated kang to warm its belly will suffice. If a young rabbit's ear tips bend forward or droop slightly, it means its body temperature is high; let it move about freely for a while to help bring the temperature down. If a rabbit's eyeballs look dull, it indicates the air in the hutch is foul, and ventilation should be carried out promptly. A rabbit running clear watery nasal discharge is a precursor of common cold,

How to detect illness in dogs? Practical methods for identifying when a dog is sick
When dogs suffer from different diseases, they will show corresponding abnormal manifestations (symptoms) in one or certain aspects. Using the following methods of examination, sick dogs can be detected. It is necessary for dog owners to master some of the most commonly used basic knowledge in this regard, so that sick dogs can be discovered in time and some simple treatment can be carried out. Never think that the diagnosis and treatment of dog diseases is only a matter for veterinarians and that "it is none of your business and you stay aloof." (1) Look. The content of looking has two major aspects: first, under quiet conditions, look at the dog's mental state, behavioral manifestations, and reactions to external stimuli; second, look at the dog's body surface condition (coat, skin, natural orifices, etc.) and the characteristics of its excrement, etc. (2) Listen. Directly listen to whether the dog's barking and breathing sounds are normal, and whether there is panting, coughing, or sneezing, etc. A stethoscope or short tube can also be used to listen to the heartbeat, breathing, and gastrointestinal peristaltic sounds. (3) Measure. Commonly use a veterinary thermometer to measure the temperature in the rectum (37.5-38.5°C for adult dogs, 38.2-39.3°C for puppies). A dog's body temperature changes regularly within a day, lowest in the early morning and slightly higher in the afternoon, and the difference between day and night generally does not exceed 1°C; if the temperature difference is too large or there is reversed fever (high in the morning, low in the evening), then it is abnormal. You can also hold the dog's ear with your hand to sense its body temperature. (4) Touch. Use the palm or back of the hand to touch a certain part of the body surface to determine the temperature and sensitivity of the skin there, muscle tension, and whether the adjacent internal organs are normal (position, size, texture, and whether there is pain). The heartbeat or pulse condition is also very easy to feel clearly with the hand. (5) Percuss. Tap the corresponding areas on the body surface (projection areas) of organs such as the dog's stomach or intestines with the fingers to judge whether they are normal.

How to treat lice in pigs? Early detection and early prevention and control are key
Pig lice (haematopinus, hog lice) are a type of wingless small insect that parasitizes the body surface of pigs, mostly parasitizing the armpits, inner thighs, lower jaw, lower neck, and the wrinkled areas of the skin on the lower side of the body, and are also numerous behind the ear flaps. Pig lice suck the blood of pigs, causing the pigs' skin to itch and their mood to become restless and agitated, and in severe cases they can also cause skin damage in pigs, emaciation and anemia, affecting the growth and development of pigs, and they can occur throughout all four seasons. Healthy pigs can be directly infected through contact with lice-carrying diseased pigs, and can also be indirectly infected through equipment, bedding straw, and the like. Pig lice reproduce quickly and are good at crawling, and once a pig is infected

The pig pregnancy detector is specialized equipment for detecting pregnancy in sows.
The reproductive performance of sows greatly affects the economic benefits of a pig farm. Estrus diagnosis of weaned sows, timely and effective mating, and return-to-estrus checks 21 days after mating are the only ways to improve sow fertility. However, pregnancy is only a physiological state, and there will always be many natural reasons that affect its continuation. An ultrasound pregnancy detector can diagnose sows that have failed early pregnancy as quickly as possible, allowing them to be re-mated early and thereby improving the production level of the breeding herd.
