How to prevent and cure common pig diseases in autumn when bacterial diseases invade with large temperature changes

Sudden cold in autumn and large temperature difference between day and night lead to frequent occurrence of pig diseases. in addition to common viral diseases, many bacterial diseases also take advantage of the opportunity to invade the body in autumn, resulting in an increase in incidence. Let's talk about the main points of prevention and treatment of common pig diseases in autumn.

1. Classical swine fever:

Classical swine fever is a highly contagious disease caused by classical swine fever virus, which can occur in pigs of all ages with high mortality. Diseased pigs have elevated body temperature, depression, lethargy, loss of appetite, constipation and diarrhea alternately, accompanied by conjunctivitis. There are often many bleeding spots or red spots in the thin skin of the ear root, abdomen and medial thigh.

Prevention and treatment: standardized introduction, regular disinfection, immunization procedures should be reasonable and effective. Diseased pigs or suspected diseased pigs should be isolated immediately, treated with anti-classical swine fever serum, or injected with 10 times the dose of classical swine fever vaccine to make pigs produce interferon. Pigs without disease were vaccinated with attenuated swine plague virus vaccine, boars were immunized twice a year, sows were injected 7-15 days before mating, piglets could be immunized in advance or once at 20 and 60 days old.

2 swine influenza:

Caused by swine influenza virus, it often occurs in late autumn or in weather with sudden changes in temperature, characterized by sudden onset, cough, dyspnea, fever, mucus secreted by eyes and nose, loss of appetite, and so on. Most diseased pigs return quickly and are often the source of all diseases.

Prevention and treatment: raise the temperature of pig house, pay attention to feeding management and environmental hygiene. It can be treated with analgin + Bupleurum + virus Ling + Dexamethasone Sodium Phosphate + penicillin.

3Streptococcosis:

Caused by pathogenic Streptococcus suis, it can be divided into septicemia type, meningitis type, arthritis type, endocarditis type and suppurative lymph node type. The affected pigs had elevated body temperature and loss of appetite, and different types of pigs had different clinical symptoms. Septicemia type and meningitis type are more serious, and the mortality is high.

Prevention and treatment: do a good job in feeding and management, environmental hygiene, routine vaccine immunization. Can be immune streptococcal vaccine, no disease in the epidemic season, can be used chlortetracycline or oxytetracycline mixed pig feed, there is disease, with sulfamethoxine, TMP, amoxicillin mixture. Large doses of amoxicillin + aminopyrine and sulfamethoxine + TMP were injected on both sides of individual pigs.

4 piglets with yellow and white dysentery:

Caused by Escherichia coli, yellow dysentery mostly occurs in 1-3-day-old piglets, white dysentery mostly occurs in 10-30-day-old piglets, the main symptoms are diarrhea, two kinds of dysentery. The color of feces is different, dehydration causes death, and the mortality rate is higher.

Prevention and treatment: strengthen the feeding tube and environmental hygiene of pregnant and lactating sows. Before parturition, sows were injected with Escherichia coli vaccine, diseased pigs were injected with colistin, and gentamicin was given to sick piglets. Sows with mastitis should be treated in time.

In short, pathogens are everywhere, strengthen feeding management, regular disinfection, reasonable immunity, scientific breeding, careful nursing is the key to disease prevention.
