立秋后天氣逐漸轉(zhuǎn)涼，較夏季直射日光的天然消毒殺菌而言，秋季病原微生物更加猖狂。加之晝夜溫差比較大，潮濕對生豬造成應激，導致秋季養(yǎng)豬疾病隱患很大，建議廣大養(yǎng)殖戶加強豬場管理，切實做好生豬疾病防控。
流行疫病的成因
入秋后，由于白天氣溫持續(xù)高溫，晚上氣溫驟降，晝夜溫差較大，容易對生豬造成應激。或經(jīng)歷過高溫高熱，生豬免疫系統(tǒng)曾受高溫損害，豬免疫力下降，部分豬仍然處于病毒排毒期，一時難以恢復健康，容易留下隱患。有些豬場因為消毒工作不到位，保健措施不當，不能有效殺滅病原微生物，導致生豬沒有足夠的抗病能力。
由于管理不當，或養(yǎng)殖戶對生豬需水量不了解，飲水設備不清潔，污染水源導致生豬感染疾病。或忽略了飼料中霉菌毒素的影響，使生豬誤食了霉變食料。有些自制配方飼料的養(yǎng)豬場沒有根據(jù)氣候變化及時調(diào)整飼料配方，使生豬生長階段與營養(yǎng)供給不匹配導致免疫力下降。
易發(fā)生的主要豬病
豬瘟、豬丹毒、藍耳病、偽狂犬病、口蹄疫、輪狀病毒、副豬嗜血、傳染性胃腸炎、仔豬紅痢、黃白痢、流行性腹瀉、附紅細胞體、弓形體、衣原體與支原體、急性風濕病等。寄生蟲病主要是疥螨類、線蟲類、吸蟲類。
防控措施
欄舍應保持適宜的溫濕度、通風，提供充足清潔飲水。適當提高豬群營養(yǎng)水平，保持合適的飼養(yǎng)密度。切實做好生物安全措施，嚴格引進豬種，引種必須要有足夠的隔離觀察期限，并采血樣檢測評估健康狀況后方可混群。養(yǎng)豬場應盡量減少霉菌毒素的危害，選購優(yōu)質(zhì)全價料或原材料，自配料的客戶要在飼料中添加高效脫霉劑——脫霉凈。應提高生豬免疫力，增強生豬抗病能力，可注射黃芪多糖注射液，誘導動物體產(chǎn)生干擾素，調(diào)節(jié)機體免疫功能，促進抗體形成。
養(yǎng)豬場應根據(jù)豬場規(guī)模，制定采血方案，科學評估豬群健康狀況，確定疫苗免疫時機、評估免疫效果、抗體消長情況，判斷生豬是否受野毒侵襲，是否在免疫空白期。做好豬群藥物保健工作，如生豬呼吸道疫情嚴重，建議選用氟苯尼考、泰妙菌素、替米考星等進行治療；消化道疫情嚴重，建議選用阿莫西林、林可霉素進行治療；血源性疾病可選用貝尼爾、長效土霉素等。應慎用藍耳病疫苗，注射期間要用抗應激藥物飲水，如用亞硒酸鈉、維生素E、維生素C連用3天，中間的一天免苗。選用康巴斯在欄舍內(nèi)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.
