as everyone knows, respiratory disease is the biggest headache, its occurrence and development is not determined by a simple reason, but in large scale pig farms if we make pigs have a good comfortable, clean environment, plus health sense, respiratory disease is no longer a problem, the key it is difficult in the details and methods, from the basics, prrs pmws, haemophilus parasuis and other respiratory diseases are the culprit, but a lot of pig disease these kind of nothing, these relatively speaking, asthma and infectious pleuropneumonia is small.
1, in the work of clearing up respiratory diseases, we should first analyze the root cause
respiratory disease is largely caused by haemophilus parasuis, haemophilus parasuis more powerful, and his stubbornness is based on the ring virus, so circovirus is arch-criminal, we first put him in control, how to control? this goes back to the starting point, any kind of disease has occurred because of environmental health has not been done, resulting in a decline in pig's resistance to environmental pathogens in high content of biological safety and infection, in the final analysis is the hygiene is bad, disinfection work not done, the vaccine did not play, most of the time are used in the treatment of, no time to engage in health, poor health and contributed to disease momentum, in the end will not spend less, no less dead pigs, very low profit or loss.
2, to purify respiratory diseases, we have to do the following
2.1 do a good job of hygiene. good health is the standard of people into the pigpen feel very comfortable, warm and comfortable, no ammonia smell as long as the pig is certainly no problem.
winter environment is not good control, we have to heat preservation and ventilation, the two is contradictory.
2.1.1 we want to put pig excrement, dung channel clean, do the "three position", the waste area of the smallest, to minimize the amount of ammonia volatilization.
2.1.2 in the morning and evening with intermittent ventilation, 15 ~ 20 minutes and then shut the window, an interval of 2 to 3 hours once again, open the window with the size according to the amount of ammonia with the temperature outside the level of decision, can open a few windows open big little fan, also can turn down a few more fan however, can not be too much too fast lest pigs catch a cold, and always feel the temperature change in the window period, at 10:00 ~ 14:00 can be opened.
2.2 treat every pig and give them a good living environment, and they will return to their owners with their profits.
2.2.1 delivery nursery is priority among priorities, each turn finished pigs to use high-pressure cleaning machine, every corner of each slot should be in place, and after drying with poison, poison to kill bacteria bacteria might alternate iodine disinfection of 3, and vacant for more than 7 days, only in this way can the removal of circovirus.
2.2.2 growth fattening house, preferably all into the whole out, even if not done, but also in the transfer to the pig before cleaning, thorough disinfection, and vacant for 7~14 days.
2.3 make reasonable immunization procedures and strictly enforce them, especially for blue ear vaccines. it is better to inject attenuated vaccine to ensure the immune effect. the classical swine fever vaccine suggested that the spleen be taken as a vaccine, such as the pig's liver. when the cell vaccine is used, it should be double used to prevent the immune failure. the development of immunization programs is very simple, only need to consider the local need to make what vaccine immune time recommended vaccine can, because can produce high quality vaccine manufacturers must have a doctor and master a large number of scientific research personnel, we have no need to change the time before and after the conflict, a few days can be adjusted.
2.4, pay attention to disinfection when the vaccine, preferably a pig for a needle, can not do when you want a nest, not allowed to use a needle from beginning to end, it is dangerous. injection should be slow, do not hit the fly needle, leakage of the need to make up an injection, filling a needle may be able to save more than a dozen of the treatment costs.
2.5 regular disinfection, 2 to 3 times a week, three or five disinfectant cycle use, such as bacteria, fungi, virus might kill du baodian, caustic soda, lime, disinfection must first clear dung, ground, walls, railings to emerge as appropriate.
2.6 regular health care, medicine and some antiviral and treatment of respiratory tract, such as turn group at weaning (28 days old) when free discharge toxins, heightening mycoplasma static, jinwei peptide growth, reduce stress, enhance immunity, prevent the invasion of pathogenic microorganisms.
2.6.1 circovirus and haemophilus parasuis in 45 days, we can turn group after adding static mycoplasma astragalus immune peptide, even two weeks after only in pigs stable transfer group after a week to care.
2.5 fourth steps to raise wages, optimize staff, formulate reasonable performance, to award less punishment, good high differential removed, let them put in place above the implementation of hundred-percent, human resources and goods is the same, a penny goods, more money brings more profit. |
