How to prevent and treat omphalitis in pigs? Pig farmers need to master these methods
1. Cause: During delivery, the umbilical cord is not strictly disinfected, or bacterial infection is caused by dirty sheds. 2. Symptoms: A few days after birth, the umbilical cord is moist and swollen, the base of the umbilical cord is red and swollen, sometimes there is an abscess around the umbilical opening, pus is discharged from the umbilical cord, ulceration occurs, the umbilical area is painful and the pig arches its back, and it is reluctant to move. Metastatic arthritis often occurs, and affected pigs have poor appetite, fever, diarrhea, and lameness. 3. Prevention and treatment: During delivery, the umbilical cord should be disinfected with iodine tincture. When the umbilical cord is inflamed, the Chinese patent medicine "Jiuyidan" can be applied externally, or penicillin can be injected around the umbilical opening; the umbilical area

Detailed Explanation of Post-weaning Multisystemic Wasting Syndrome in Pigs (Part Two)
4 Prevention and Control PCV2 is highly resistant to inactivation by many detergents and disinfectants, and the effect of medication is limited. Therefore, it is crucial for pig farms to take measures such as changing rearing techniques, improving hygiene conditions, and reducing stress at different stages, in order to lower the "infection pressure" (including PCV2 and any other pathogens). 4.1 Farrowing Period 4.1.1 All-in/all-out, with thorough cleaning and disinfection between two batches of pigs. 4.1.2 Wash sows and deworm them before farrowing;

What are the main aspects of the effects of airflow on pigs?
The movement of air molecules is called airflow, and airflow that moves horizontally is called wind. Atmospheric airflow is formed when uneven temperature distribution on the Earth's surface creates pressure differences, and air molecules flow from low-temperature high-pressure areas to high-temperature low-pressure areas. In meteorology, wind is commonly described by wind speed and wind direction. Wind speed is the distance the wind moves per unit time (m/s); wind direction is the direction from which the wind blows, expressed in 8 or 16 directions, and based on the probability of wind appearing in each direction, a wind direction frequency diagram (wind rose diagram) is drawn. Wind direction frequency diagram

How to prevent cross-infection in pigs? Key points for safe injection
(1) Sterilization of vaccination equipment. Syringes, needles and other equipment used for vaccination must be strictly sterilized and disinfected as required. (2) One pig, one needle. Strictly prevent the injection method of using one needle to the end. It is best to use one needle per pig, changing the needle for each pig injected. (3) Order of emergency vaccination. During emergency immunization, vaccination should be carried out in the order of relatively clean herds; assumed healthy herds; threatened herds; and affected herds. Within an affected herd, proceed in the order of asymptomatic; mildly symptomatic; and severely symptomatic. (4) Safe and scientific

What are the simple methods for identifying sick pigs?
1. Watch the movements. A healthy pig's tail keeps swinging, and it responds quickly and sensitively to external stimuli. A healthy adult pig is greedy for food and fond of sleep. If food is given, it will come at the call; after eating its fill, it lies down and dozes; when a stranger approaches, it stands up, raises its head, and keeps wagging its tail. If a pig is found to be listless, sluggish in movement, often lying down and unable to get up, refusing to eat, with a stiff back and unsteady walking, and with its head and tail drooping, then it is a sick pig. 2. Look at the skin. A healthy pig has smooth, round skin and full muscles; if the pig's skin is rough and hard and lacks elasticity, with swelling, ulcers, red spots, rotten patches, etc., these are signs of disease.

Prevent Allergic Reactions When Using Streptomycin in Pigs and Cattle
Some pigs and cattle develop allergic reactions after being given streptomycin. If rescue treatment is not timely or not appropriate, it can cause death, just like penicillin allergy. Therefore, streptomycin use in pigs and cattle must not be taken lightly; after administration, observe the animals carefully and be prepared for emergency treatment. Streptomycin allergy in pigs and cattle mostly occurs acutely. With the first dose, the allergic reaction develops somewhat slowly, with symptoms appearing in about 10-15 minutes; with the second dose, the allergic reaction develops more quickly, with symptoms appearing in about 5 minutes. The main symptoms are: pigs and cattle tremble all over

How to prevent and treat runt pigs? Pig farmers need to master these methods
Runt pigs, commonly known as "cushion-nest pigs", "little old man pigs", "iron pigs". During the growth and development stage, pigs suffer from the influence of certain adverse factors, their development is stunted and growth stops. Although such pigs are old in age, they are very small in size, with rough and messy bristles and extreme emaciation, forming a body shape that is pointed at both ends and large in the middle; they eat feed but do not gain meat, causing pig farmers to suffer great losses. 1 Manifestation characteristics Runt pigs mainly show a small, thin and weak body, stunted growth and development, abnormally excited spirit, restlessness, rough back hair, dull skin without luster, and decreased elasticity.

Correct Surgical Castration Methods for Pigs
Surgical castration of meat pigs is a traditional practice in our country, but the appropriate castration method should be adopted according to different circumstances to achieve the desired results. Based on many years of clinical experience, the author now introduces several common castration methods for the reference of fellow practitioners. Castration method for boars: The pig is restrained in dorsal recumbency, and the surgical site is routinely disinfected. The surgical site is selected 2cm from the last pair of teats along the midline, and the skin is incised backward, with the size of the incision depending on the size of the testicles. The subcutaneous tissue is bluntly dissected until one side of the tunica vaginalis is exposed, and the testicle is pressed with a finger to bring it close to the incision; at this point

How are affected pigs identified? The Ministry of Agriculture publishes the criteria
Recently, the Veterinary Bureau of the Ministry of Agriculture and the China Institute of Veterinary Drug Control jointly compiled and issued the "Safe Use Manual for Inactivated Vaccine against Highly Pathogenic Porcine Reproductive and Respiratory Syndrome," publishing the quality standards for the inactivated vaccine against porcine reproductive and respiratory syndrome, and also publishing the criteria for identifying affected pigs. The manual stipulates that the criteria for identifying affected pigs are: a body temperature above 41°C for at least 3 days; decreased spirit and appetite, conjunctivitis, and respiratory symptoms such as coughing and wheezing; and on gross necropsy, patchy consolidation appearing in the apical or cardiac lobe of the lungs. Meeting the above three criteria means

How to scientifically improve the nutritional level of pigs
1. Nutrition of gilts. The nutrition of gilts and the related nutritional reserves are important factors affecting the lifelong performance of sows, and their nutritional level should ensure the body's needs during the reproductive period after maturity. Starting from a body weight of 45 kg, the diet level should be 0.1% higher than the usual growing-finishing pig diet to enhance the skeletal development of gilts. After gilts reach about 150 days of age and enter the replacement gilt herd, their growth should be controlled, with restricted feeding (2.3-2.8 kg/day) of a medium-energy, high-protein diet to reduce
