In order to prevent viral diarrhea, attenuated vaccines for infectious gastroenteritis and epidemic diarrhea can be used. The method is to immunize sows twice before delivery 15 and 7 days after delivery, and piglets get passive immunization through breast milk. Using Clostridium formalin type C aluminum hydroxide toxoid, sows were injected with 5ml intramuscular 1 month before labor, and then injected with 10ml half a month before labor, or injected with Clostridium welchii type C vaccine in the third trimester of pregnancy.
To prevent yellow and white dysentery, Escherichia coli genetic engineering vaccine can be used (bivalent, trivalent and tetravalent vaccines can be used according to the instructions).
To prevent piglet paratyphoid, paratyphoid vaccine can be taken orally at the age of 30 days.
(2) Reasonable preparation of piglet feed
That is to say, it is necessary to ensure the growth demand of piglets, and the protein content should not be too high, especially the plant protein.
(3) Adding fiber feed properly
Adding fiber (3% ~ 5%) such as grass powder to the feed of weaned piglets can not only promote the development of intestinal tract, but also inhibit the growth of harmful bacteria through large intestine and maintain the digestive function of gastrointestinal tract.
(4) Drug prevention
Formula 1: add 100g Zhiyuan Jing +400g chlortetracycline or 150g doxycycline to each ton of feed 1 week.
Formula 2: Add 100g metronidazole per ton of feed.
Formula 3: add 1% ~ 2% Chinese herbal medicine Lobelia chinensis powder to the feed.
(5) Improve the management system
Do a good job in health and epidemic prevention, strengthen disinfection and provide a suitable environment.
(6) Application of non-antibiotic preparations
Enzyme preparation can make up for the deficiency of endogenous digestive enzymes in pigs; Acid preparation can improve the acidity in the stomach; Humic acid has excellent physiological activity and chemistry, which improves feed reward; Probiotics can regulate the pattern of intestinal flora and inhibit the reproduction of harmful microorganisms. The above four non-antibiotic preparations have good effects on preventing piglet diarrhea.
(7) drug therapy
Formula 1: 0.5g ampicillin (1) is dissolved in 5ml of enrofloxacin injection, and 15 ~ 25kg piglets are mixed for intramuscular injection.
Formula 2: After the injection of sulmisacin, Xue Hai injected 5ml.
Formula 3: Gentamicin 40000 units+vitamin B2 complex mixed intramuscular injection, 1, twice a day.
