Pig disease prevention and control should be based on strengthening feeding management, prevention, prevention before cure. Includes three elements: control of swine disease immunization, medical health care and biological safety, the medicine health care is a very important link, is also the most easily overlooked. At present, China's modern intensive pig farms generally advocate the use of key phase and pulse type of preventive health care drug use program, to achieve the transformation of treatment veterinary medicine to health care veterinarian. In order to improve the production level and economic benefits of pig farms, and guide the rational use of swine at various stages of pig production, we carried out some exploration on the health care drugs in pig farms, and achieved good results. The relevant content is summarized in order to discuss with peers.
Medication regimen (all regimens were added to the amount of water or feed per 1kg)
To reduce stress, eliminate toxins in pigs, and improve the body's resistance to disease based drugs

Swine stage drug care
1 backup sows health care
Control the occurrence of respiratory diseases and prevent the emergence of bacterial or viral diseases. Elimination of pathogenic bacteria and endotoxin in the reserved sows, inhibition of virus quantity and activity in the body, and purification of common diseases in pig farms. Strengthen the physique of the backup sow, improve the immunity of the body, promote the estrus, and obtain the best breeding rate.
The introduction of replacement pig in the first week, in order to reduce stress, promote the rapid recovery of the physique, ensure the healthy groups, according to the conditions of the program of N1.1.1, 1.1.2, take 1.2.10 in the drinking water, or mixture of health care administration.
Reserve pig breeding period: mainly to reduce respiratory tract, intestinal diseases and the occurrence of red blood cells, and improve the body's resistance to disease. Health care should be based on the pig farm and the surrounding situation, select or rotate medication, 7 d a month until the breeding. According to the conditions and selection scheme 1.1.3, 1.1.5, 1.2.2 column, 1.2.3, 1.2.4, 1.2.7 in need, if there is a pig around PRRS PMWS existed or happened pleuropneumonia, available Kim florfenicol 60 mg 100 mg+. If pigs have Pasteurella, Salmonella, Haemophilus suis and other pathogenic bacteria may exist, you can use the Fu 100 mg+ cephalosporin 60 mg.

.2 sow health
Remove toxins from the body, clear the intestines, strengthen the body and improve immunity. Prevention of various diseases through the vertical transmission of placenta to the fetus, improve the quality of pregnancy.
Open and weaned sows: in order to enhance the body's resistance to diseases, improve the conception rate, feed can add some antibiotics properly, but as the herd health status and decided on site. Such as oxytetracycline premix, fluoride Qi (the main component of 20% florfenicol), a potent lygo (the main component of 2.2% +4.4% of lincomycin and spectinomycin), red bow in chain (the main component of sulfamonomethoxine sodium and trimethoprim 2%, Benil 10% and traditional Chinese medicine extract, etc.). Or in the mating before intramuscular injection of advanced furosemide (main component long-acting cephalosporin), Xin Yue first (main component long-acting oxytetracycline) and so on. According to the conditions or needs of 1.2.2, 1.2.3, 1.2.4, 1.2.5, 1.2.7 and other compound formula, the effect is better.
Pregnant sows: mainly to prevent chlamydia and red blood cell infection, prevent blue ear disease (PRRS) and PCV virus, such as sow breeding obstacles. Some appropriate antibiotics added in the first week of pregnancy early and late feed, such as fluorine, fluorine odd peptide, potent intestinal teshin, mycoplasma, lygo (mainly static tylosin), and feed additive of sodium selenite and VE, depending on the situation in the whole period of pregnancy feed add drug prevention of mycotoxin (Mei Duqing). 1.1.3, 1.1.4, 1.2.2 and 1.2.9 can be selected according to the conditions or needs.
Perinatal health care: mainly to purify the maternal environment, reduce the vertical spread of respiratory and other diseases, and enhance the resistance and stress resistance of sows. Prenatal two weeks postpartum in the feed to add some appropriate antibiotics such as fluoride, fluoride, potent peptide odd, intestinal teshin, lygo Xingkang (the main component of enrofloxacin, amoxicillin) powder, chlortetracycline etc.. The focus of visual health care options or rotation using 1.1.3, 1.2.1, 1.2.3, 1.2.4, 1.2.7, 1.2.8 compound formula. Prenatal, according to the situation, intramuscular injection of lead (main component long-acting cephalosporin), Xin Yue first (main component long-acting oxytetracycline) and so on. |
2.3 kinds of boar health care
Increase boar resistance to disease and improve mating ability. According to the season and the actual situation of the pig farm, the interval is changed for a period of time or every month. You can use 500 oxytetracycline premix, fluoride, fluoride, potent peptide odd, Ligao enrofloxacin powder and other antibiotics, each feeding a week. The compound formula is 1.2.2, 1.2.3, 1.2.4, 1.2.7.
Suckling piglets
Newborn piglets health: mainly prevent newborn suckling pig diarrhea, enhance the physique of piglets, prevent bacterial, viral diseases. Improve the growth rate and survival rate. The following options can be selected according to the circumstances:
2.4.1 advanced furosemide (main component long-acting cephalosporin), Xin Yue first (main component long-acting oxytetracycline) and other 3 needle health plan: 3, 7 and 21 days old, according to the instructions injection.
Eat colostrum before oral enrofloxacin powder, gentamicin, norfloxacin or oxytetracycline half 2.4.2 piglets.
2.4.3 piglets were injected at kg per body weight after birth with advanced furosemide or unmatched cephalosporin. Piglets iron supplementation: 3 days old iron (such as disease resistance, promoting the growth of blood, acupuncture, blood, Chong Xin, blood, blood, etc.), selenium (sodium selenite, VE), with disease resistance to promote long blood needle, no need to add selenium. At the age of 7 days or so open food feed before and after medication before weaning feed feed properly adding some anti stress drugs such as Jin Wei growth peptide (the main component of Jin growth peptide (electrolytic multidimensional etc.) etc.) and Zhengchangsheng, when necessary, some antibiotics such as strong effect, lygo enrofloxacin powder, Chang Taixin, Kang, zhilishen the storm in the diet.
2.5 health care is usually administered 1 weeks before weaning and 2 weeks after weaning. In order to reduce all kinds of stress during weaning, strengthen the physique, improve the immunity and survival rate of piglets. Prevention of diarrhea, respiratory diseases and edema after weaning, and reduce the incidence of PMWS. The health care plan can refer to the contents listed in 1.1.1, 1.1.3, 1.1.4, 1.2.3, 1.3.4 and 1.2.3.
2.6 growing finishing pigs
It mainly inhibits virus reproduction and prevents the occurrence of respiratory diseases and red blood cells. Improve body immunity, enhance physique, shorten slaughter time and raise feed ratio. Generally used in the early 6~8 D, and later 5~7 D, each pig farm because of the different circumstances, medication time and the focus of a big difference, and pay attention to drug withdrawal period. The program is optional, refer to the contents listed in 1.1.3, 1.1.4, 1.1.6, 1.2.2, 1.2.4 and 1.2.5 respectively.
Expel parasites inside and outside the body of pigs and destroy them in larval form to prevent re infection. When selecting worms, select the time, cover the whole population, and take phased and preventive medication. We should pay attention to clean the environment thoroughly, strengthen the management of feces and prevent re infection.
3.1 herd worm time
Sows are given 14~21 D prior to birth to prevent worms, so that the sow is free of worms after birth, so that the piglets will not carry worms. The reserve sows should be used 14 times 1 d before mating. Boars should be given 1 times a year, at least 2 times a year. At 35~40 D, the most economical way to get rid of worms and fattening pigs is to keep them at the end of the slaughter. The introduction of pigs to isolation, after deworming, finally to gregarious; if the pig louse is more, should be at intervals of 10 d about second times of medication, for serious disease of swine Sarcoptes scabiei infection, can use drug 1 times.
3.2 methods of expelling insects
The best choice for insect repellent is the compound medicine with comprehensive function. The major pig is sarcoptidosis, lice and nematodes, suitable dosage form is injection, premix. Optional
