The main direction of farm management in the autumn is to timely respond to the related diseases caused by climate change. There is a large temperature difference between day and night in autumn, and the temperature will go through a high-to-low transition process. At this time, the temperature change is a great stress to the pigs at all stages, weakening the pig's constitution, resulting in a decline in the ability of pigs to resist diseases. Therefore, Poor management affects pigs very hard.
The main focus of autumn management is to enhance the pig's own constitution, improve anti-stress ability, and reduce various stress factors on the body's damage. The first is the change of temperature. The fluctuation of temperature and temperature and the increase of temperature difference between day and night will aggravate the consumption of the pig's own nutrient reserve. At the same time, the normal circadian rhythm of the pig has also changed. This has the greatest impact on the respiratory system. The cooler air enters the upper respiratory tract of the pig and increases the irritation of the mucous membranes of the respiratory tract, and the stimulation of harmful gases such as ammonia gas makes the respiratory defense system in a state of tension. It is easy to induce the upper respiratory tract infection pathogenic microorganisms to become inflamed and gradually intensify. Become pneumonia, with severe cough and asthma, etc., have a great impact on the body. The pigs showed symptoms of rough hair, weight loss, and intractable respiratory diseases. At this point there are other pathogens that are infected or lurking, which will increase the power of the disease and cause huge damage to the body and even death. Therefore, the management of farms in autumn and winter is not a single or independent link, but an integral part of the entire pig-raising process. The first is to find ways to reduce the impact of stress factors on pigs, and at the same time to improve the pig's constitution as the core of farm management; second is the purification of sow disease (recessive consumptive disease), especially noxious diseases and autumn Prevention and control of epidemic diseases in winter, epidemic prevention is the focus of this season's management work, to strengthen the attention of swine fever, Japanese encephalitis, pseudorabies, foot-and-mouth disease, epidemic diarrhea and other multiple diseases; Another focus is the removal of recessive pathogens, For example, mycoplasma, erythroblasts, etc., mainly rely on the timely addition of health care drugs, and seizing monthly regular health care is an important part of production safety.
Then there is the problem of the nutrition of the pigs. Seasonal characteristics lead to the quality of raw materials for feeds as a bottleneck restricting the development of the pig industry. Chen corn is relatively tight, new corn is already on the market, and many pig farms choose to use other raw materials (sub powder or DDGS ) instead. In short, whether it is new corn or other raw materials instead of energy feeds, as the demand for nutrients from pigs is also increasing during this season, the imbalance between such nutrient supply and demand can be in sharp contradiction. One of the most vulnerable is the vitamin supply. Insufficient, which makes the pig mainly showed coarse hair disorder, skin scarring, hoof cracking, weight loss and reproductive failure and estrus. It is rainy in autumn, the weather is humid, and the humidity of new corn is so large that it is too late to dry and dry. This is a detrimental factor for feed materials with long storage time. This can cause serious illness of stored molds, leading to deterioration of raw materials and direct reduction in the contained nutrients. Ingredients, and the most serious damage to vitamins, plus some farms directly use some inferior de-mold agents (adsorption of mycotoxins also absorb vitamins, mainly in polar small molecule vitamins) again to destroy the feed nutrition, resulting in Pigs are severely malnourished and their resistance is reduced, which increases the stress and the chance of developing the disease.
Weiyuan's recommendation for the special climate in autumn and winter: Breeding group use Zhongwei Yinqiaosan + Myricin + Weipujian/Tilmicosin, use 7 days -10 days per month; full use of Neumann Neumann + Weijuenengxing has long-term use; piglets use Zhongwei Yinqiaosan+Merolisu+Zweitite/tilmicosin/Yiguanlin spices, and are used continuously for 7 days to 10 days before and after weaning; Group to do epidemic prevention at the time of use to help Yisheng + shaped star spices, continuous use of 5 days -7 days; to strengthen the whole group of insecticide, use Weiyuan Jinyiwei unified spices, use 7 days -10 days, severe half months After repeated use once; strengthen environmental disinfection, use Jin Weikang 1:800, 2 times - 3 times a week, the entire field of disinfection.
