Misunderstanding of Clinical treatment and medication in Pig Farm

Dexamethasone sodium phosphate. The drug is used to treat inflammatory and allergic diseases. The daily dosage of pigs is 4 mg ~ 12 mg. It used to be used for simultaneous delivery of female animals. In recent years, it is common for farmers to abuse and overuse dexamethasone. For example, in a pig farm, due to the increase of body temperature of suckling and weaning piglets, the injection volume of each piglet reaches 10 mg ~ 20 mg, or even continuous medication, which not only can not solve the fundamental problem of the disease, but also affects the survival rate and growth and development of piglets.

Oxytocin injection. It is mainly used for sow midwifery and labor induction. At present, the drug is mainly used by farmers before delivery (after broken amniotic fluid), during delivery (after giving birth to 2 piglets) and after delivery, and it is necessary for each fetus to evolve from midwifery before delivery to delayed delivery and dystocia. Large doses of oxytocin also promote early lactation, which is not coordinated with the needs of lactating piglets, and even results in inhibition of lactation or no lactation syndrome. Therefore, we should pay attention to the abnormal fetal position of parturient sows and avoid using oxytocin when the birth canal is narrow. It is recommended that oxytocin should be used to promote the discharge of placenta after delivery.

Penicillin powder injection. There are two kinds of penicillin potassium and penicillin sodium on the market, which need to be diluted with sterilized injection water. Some farmers like to choose traditional Chinese medicine (Chinese herbal medicine) injection dilution, such as Ma Xing Shigan injection, when the temperature is low, it is easy to appear flocs, so that it can not be used during injection; some are diluted with lincomycin injection, resulting in turbidity, flocs or precipitation, which seriously affect the efficacy; some are diluted with sulfonamides, because sulfonamides injection is strongly alkaline, and mixed injection with this product can destroy the antibacterial properties of penicillin. Some farmers choose aminopyrine and analgin for a long time to dilute this product, which will cause granulocytopenia in sows and affect the immune effect.

Lincomycin injection. Clinically, it is used for the treatment of Gram-negative bacteria infection in livestock and poultry, especially penicillin-resistant bacteria that are sensitive to this product, and can also be used to prevent and cure porcine dysentery caused by Treponema pallidum and porcine asthma caused by mycoplasma. Some farmers use this product injection to give oral administration to piglets, some inject suckling piglets, and even cause adverse consequences by injecting pregnant sows. Oral administration of lincomycin can cause fatal diarrhea and intestinal edema in horses, rabbits and other herbivores. Inject this product into pigs and stimulate the pain.

Tilmicosin injection. Some farmers use this product to treat infected animals to cause death, some use this product with aminophylline injection, some use this product plus dexamethasone to treat piglet asthma (pleural effusion) and cause death. Tilmicosin injection mainly acts on the cardiovascular system, which can cause tachycardia and weakening of contractile force, and local reactions (edema, etc.) may occur after intramuscular and subcutaneous injection.

Chloramphenicol. Chloramphenicol has been banned in animal clinic, and there are thiamphenicol premixtures, florfenicol premixtures and florfenicol injection (10%, 20% and 30% specifications) on the market. Some farmers add high concentration of florfenicol premix to the feed of piglets. Some pigs will be injected with this injection as soon as their body temperature rises and respiratory symptoms appear. Although florfenicol does not inhibit bone marrow, it has embryotoxicity and is prohibited in pregnant sows and has a certain immunosuppressive effect. According to relevant data, florfenicol injection has the highest drug concentration in the uterus, followed by lung and intestinal tract, so attention should be paid to the compatible application.
