  • The previous batch of pigs had blue ear disease (porcine reproductive and respiratory syndrome). How should the pen be disinfected?

    1. Cleaning and washing. Remove all contaminants and bedding from the pen, and sweep down the dust from the ceiling as well. Then pile it all together to ferment. Then rinse thoroughly with clean water. 2. Disinfection of the floor and walls. For the floor, use caustic soda or sodium hydroxide. For the walls, spray with iodine-based or chlorine-based preparations. 3. For metal equipment that is not afraid of heat but is afraid of corrosion: use a blowtorch (alcohol blowtorch, kerosene blowtorch). 4. For enclosed pens: fumigation. Peracetic acid, formaldehyde, or potassium permanganate can all be used. After sealing for 2 hours, ventilate for 7-10 days. Basically it takes half a month.

At the top, leaves grow in clusters; the leaf stalks are thick and long; the leaf blade is broadly ovate-triangular, with length and width almost equal, tripinnatifid, and the ultimate segments are falcate-lanceolate,

  • How to Prevent and Treat Porcine Unknown High Fever Syndrome? A Detailed Guide to Practical Methods

    "Porcine unknown high fever," also known as porcine high fever syndrome, is a disease with both high morbidity and high mortality, occurring mainly in growing-finishing pigs and some sows. The main clinical signs in affected pigs are elevated body temperature, listlessness, poor appetite or complete loss of appetite, difficulty breathing and panting; some pigs also show reddened to purplish skin, and a few have bleeding points at the hair follicles. The pathogens are mainly mixed infections and secondary infections involving multiple viruses, bacteria and parasites, including classical swine fever virus (HCV), porcine reproductive and respiratory syndrome virus (PRRSV), swine influenza virus (SI

  • Wet urine syndrome in foxes is a disease with a relatively low incidence rate

    Foxes also suffer from wet urine syndrome, but the incidence rate is usually relatively low, with the onset period mainly from July to September. The incidence rate is higher in male foxes than in female foxes, and growing foxes with fast growth rates as well as lactating female foxes are also susceptible to this disease. It is generally believed that the occurrence of this syndrome is related to oxidative deterioration of feed, excessively high fat content in feed, and deficiency of vitamin B1, E, A and choline chloride. When wet urine is found in foxes, first investigate whether there have been any problems with the feed recently. If the feed indeed has problems in quality and other aspects, immediately change or replace or adjust the feed composition, ensure freshness, and supplement vitamin B1,

  • Key Points for Preventing and Treating Chicken Intestinal Toxemia Syndrome in Late Autumn

    In late autumn, the climate changes abnormally, with large temperature differences between day and night. Broiler chickens and laying hens often develop intestinal toxemia syndrome, characterized by diarrhea, undigested feed in the droppings, a marked drop in feed intake, slow growth, weight loss, and dehydration. Necropsy of dead chickens reveals brain fluid in the head, reddened thymus in some birds, swelling of the duodenum, and thickening of the intestinal wall, which feels very hard to the touch. There is no feed in the intestinal tract, the intestinal mucosa has sloughed off in large amounts, and some intestinal segments contain frothy material and tomato-like droppings. The gallbladder becomes smaller and pale yellow,

  • Diagnostic Key Points and Treatment Methods for Chicken Intestinal Toxemia Syndrome

    Due to abnormal climate changes, the temperature difference between day and night varies greatly, and broiler and layer chickens often develop intestinal toxemia syndrome characterized by diarrhea, undigested feed in the feces, a significant drop in feed intake, slow growth, weight loss, dehydration and a decline in feed conversion efficiency. I. Clinical symptoms The flock is still in fairly good spirits, but grows slowly, and the combs are pale. Some diseased chickens pass white strip-like or mucus-like feces containing undigested feed, and the feces are slightly yellow. A few chickens show listlessness, head retraction, head tremor, running about restlessly and easy startling,

  • What exactly is dog hand fear syndrome

    When dealing with dogs, the handler should try to play only the role of showing affection and giving commands. And must never leave the dog with any impression of threat or intimidation.

  • Symptoms and Prevention Methods of Duck Arthritis Syndrome

    1. Main symptoms. Sick ducks mainly show joint swelling, most commonly in the hock joint, followed by the knee joint, hip joint and toe joints. The affected joints are swollen and purplish-red, feel hot on palpation, are relatively soft at the beginning and then gradually harden, with severe lameness or inability to walk, reduced feed intake, gradual weight loss and increased mortality. 2. Preventive measures. The disease is associated with a variety of bacterial infections, such as Staphylococcus, Salmonella, Riemerella anatipestifer, etc. In the feeding system, the "all-in

  • How to diagnose and prevent sudden death syndrome caused by Clostridium welchii in pigs?

    Sudden death syndrome caused by Clostridium welchii in pigs, also known as pig red intestine disease, is an enterotoxemia in pigs caused by Clostridium welchii types A, C and D. 1. Onset symptoms The disease generally has no premonitory symptoms and presents as sudden death. Some affected pigs may also be seen before death with mania and restlessness, ataxia, hoarse squealing, abdominal distension, difficulty breathing, sudden collapse, frothing at the mouth, muscle tremors, paddling of the limbs, pale skin, opisthotonus, and death within 1 to 3 hours. 2. Pathological changes Dead pigs are in good body condition, with complete rigor mortis

  • What are the causes and stress factors of swine high fever syndrome?

    Causes: Swine high fever syndrome is essentially a swine disease caused by mixed infection with multiple viruses, bacteria and protozoa triggered by immunosuppressive swine diseases. Biological factors: mixed infection with pathogens such as classical swine fever virus, circovirus, porcine reproductive and respiratory syndrome virus, pseudorabies virus, Eperythrozoon, Toxoplasma, Streptococcus, Salmonella paratyphi, Mycoplasma, Actinobacillus pleuropneumoniae, Haemophilus parasuis and Pasteurella. There can be more than 15 kinds of pathogens, among which classical swine fever virus has the highest infection rate and is the most typical; mixed infection with Toxoplasma, Eperythrozoon, porcine reproductive and respiratory syndrome virus, circovirus and classical swine fever virus is common, and there is also mixed infection of classical swine fever virus with piglet paratyphoid bacillus, often dominated by classical swine fever virus, together with one or more than two kinds of viruses, bacteria and protozoa, so the mortality rate is high, the cure rate is low, and it may even wipe out the whole herd.
