立秋后天气逐渐转凉，较夏季直射日光的天然消毒杀菌而言，秋季病原微生物更加猖狂。加之昼夜温差比较大，潮湿对生猪造成应激，导致秋季养猪疾病隐患很大，建议广大养殖户加强猪场管理，切实做好生猪疾病防控。
流行疫病的成因
入秋后，由于白天气温持续高温，晚上气温骤降，昼夜温差较大，容易对生猪造成应激。或经历过高温高热，生猪免疫系统曾受高温损害，猪免疫力下降，部分猪仍然处于病毒排毒期，一时难以恢复健康，容易留下隐患。有些猪场因为消毒工作不到位，保健措施不当，不能有效杀灭病原微生物，导致生猪没有足够的抗病能力。
由于管理不当，或养殖户对生猪需水量不了解，饮水设备不清洁，污染水源导致生猪感染疾病。或忽略了饲料中霉菌毒素的影响，使生猪误食了霉变食料。有些自制配方饲料的养猪场没有根据气候变化及时调整饲料配方，使生猪生长阶段与营养供给不匹配导致免疫力下降。
易发生的主要猪病
猪瘟、猪丹毒、蓝耳病、伪狂犬病、口蹄疫、轮状病毒、副猪嗜血、传染性胃肠炎、仔猪红痢、黄白痢、流行性腹泻、附红细胞体、弓形体、衣原体与支原体、急性风湿病等。寄生虫病主要是疥螨类、线虫类、吸虫类。
防控措施
栏舍应保持适宜的温湿度、通风，提供充足清洁饮水。适当提高猪群营养水平，保持合适的饲养密度。切实做好生物安全措施，严格引进猪种，引种必须要有足够的隔离观察期限，并采血样检测评估健康状况后方可混群。养猪场应尽量减少霉菌毒素的危害，选购优质全价料或原材料，自配料的客户要在饲料中添加高效脱霉剂——脱霉净。应提高生猪免疫力，增强生猪抗病能力，可注射黄芪多糖注射液，诱导动物体产生干扰素，调节机体免疫功能，促进抗体形成。
养猪场应根据猪场规模，制定采血方案，科学评估猪群健康状况，确定疫苗免疫时机、评估免疫效果、抗体消长情况，判断生猪是否受野毒侵袭，是否在免疫空白期。做好猪群药物保健工作，如生猪呼吸道疫情严重，建议选用氟苯尼考、泰妙菌素、替米考星等进行治疗；消化道疫情严重，建议选用阿莫西林、林可霉素进行治疗；血源性疾病可选用贝尼尔、长效土霉素等。应慎用蓝耳病疫苗，注射期间要用抗应激药物饮水，如用亚硒酸钠、维生素E、维生素C连用3天，中间的一天免苗。选用康巴斯在栏舍内定期消毒。
The English version
After beginning of autumn, the weather turn gradually cool, summer natural disinfection sterilization, direct sunlight fall more rampant pathogenic microorganisms. Combined with the day and night temperature difference is bigger, damp cause stress to the pig, in the autumn pig disease risk is very big, suggest that the broad masses of farmers in order to strengthen the management of pig farms, earnestly pig disease control and prevention.
The cause of epidemic disease
After autumn, because the temperatures continue to heat during the day and night temperatures plummet, day and night temperature difference is bigger, easy to cause stress to the pigs. Or had high temperature high fever, pig immune system damage under high temperature, the pig immune suppression, part of the pig is still in a virus detoxification period, difficult to restore health, easy to stay hidden. Some pig farms because disinfection work does not reach the designated position, improper care measures, can effectively kill pathogenic microorganism, cause pig didn't have enough resistance.
Because of mismanagement, or farmers do not understand pig water demand, water fountain is not clean, water pollution cause pig disease. Or ignore the effect of mycotoxins in feed, makes pigs fed mildew to change the food. Some homemade formula feed pig not according to climate change, timely adjust the feed formulation pig growth stage and the nutrition don't match led to the decrease of the immune system.
The main swine disease easily occurs
Swine fever, swine erysipelas, blue ear disease, pseudo rabies, foot and mouth disease, rotavirus, deputy pig blood, infectious gastroenteritis, piglet red dysentery, epidemic diarrhea, dysentery, huangbai is attached to the red cell body, toxoplasma gondii, chlamydia and mycoplasma, rheumatic fever, etc. Parasitic diseases mainly scabies mites, nematode, fluke.
The prevention and control measures
Bar should maintain appropriate temperature and humidity, ventilation, and provide adequate clean water. Improve the level of swine nutrition appropriately, maintain appropriate breeding density. Earnestly biosecurity measures, strict import pig breeds, introduction must have enough quarantine period, and blood sampling for mining evaluation rear can mix group of health. Pig should try to reduce the harm of mycotoxin, high-quality full material or raw material of choose and buy, the ingredients of a customer to mildew remover is added in the feed efficiency, take off the bad net. Should strengthen the pig disease-resistant ability, improve the immunity of live pigs, injectable astragalus polysaccharide injection, induced animal body produce interferon, regulate the body's immune function, stimulative antibody formation.
Based on scale pig farms, pig farms should blood solution, pigs health and scientific assessment to determine the vaccine immunization time, evaluate the immune effect, growth and decline of the antibodies, and determine whether pigs by wild poison, whether in the immune blank period. Completes the pigs drugs health work, such as pig respiratory disease severity, suggest that choose fluorobenzene nicol, magnitude, tai miao rhzomorph, telmisartan test for treatment; The epidemic situation of the digestive tract is serious, it is recommended that the use of amoxicillin, clindamycin treatment; Blood-borne diseases can choose Mr Neil, long-acting oxytetracycline, etc. Should be careful with blue ear disease vaccine, want to drink with anti-stress drugs during injection, such as sodium selenite, vitamin E, vitamin C, 3 days, in the middle of the day from seedlings. Selects the compas in column inner regularly to disinfect.
