Autumn is a golden period for pig farmers. The cool climate and suitable humidity are best suited for pig growth. Therefore, pig farmers need to seize the key period of autumn to raise the technical level of raising pigs so as to increase production and increase efficiency.

Pay attention to doing a good job of keeping warm and ventilating

From hot summer to cool autumn, the temperature drops sharply, and the temperature difference between day and night also increases. The temperature difference in the north reaches more than 10°C. Occasionally, there will be strong winds, and even many places will feel the taste of winter in a short time. It has a great impact on the growth of pigs, especially wet and cold concrete floors, which not only greatly increase the incidence of herds, but also reduce the feed remuneration of pigs. For piglets, this climate change will also cause diarrhoea and diarrhoea, causing many diseases. Therefore, appropriate measures should be taken at this time to control the temperature in the pig house and reduce the impact of the temperature difference. It has become a task that the farm chief must consider and implement. The specific measures are as follows:

(1) Maintenance of pig houses: Intrusion of thieves into the pig house to attack pigs can cause diseases such as colds and pneumonia in pigs. Therefore, every house should be repaired, such as doors, windows, glass, and protective covers, etc., and must be closed at night. Doors and windows to prevent all kinds of thieves; can also be used from the outside with a roller blind (single or double plastic film, plastic cloth) for insulation.

(2) Adding insulation layer to the pig house: Closed-type pig house, with a height of 1.8 to 2.0 meters above the ground from the ground, adding sawdust and rice husk to the shed, laying grass on the ground for the pig to lie down. A vent is left every two days in the ceiling to remove ammonia and moisture from the house. Conditional farms can use heating and infrared light bulbs at night. No conditions can also be used to cover plastic sheeting, hanging grass curtains and other measures to keep the pig house at a suitable temperature. The suitable temperature for 1 day to 3 days is 30°C to 32°C, the suitable temperature for 4 days to 7 days is 28°C to 30°C, and the suitable temperature for 15 days to 30 days is 22°C to 25°C. . The temperature of the nursing house should be kept above 20°C, the temperature of the nursery and the nursing house should be kept above 22°C, and the temperature of the newly weaned piglets should be maintained at about 26°C.

(3) Pay attention to ventilation and ventilation of the pig house: The pig house should be insulated, ease the temperature difference and strengthen the ventilation, prevent air pollution, and make reasonable adjustments according to the actual situation. If there is more ventilation in sunny days and less ventilation in rainy days, it is better to choose ventilation time for higher temperatures. Generally, the best time for ventilation is from 10 am to 3 pm.

(4) Adding nutritional supplements: Forwell's products, Forwell (pig), 500 tons of mixed spices, 1 ton, drinking water, 1:2000. At the same time, we can use the micro-ecological agent Vivienne (specialty for farms), add 500 g/ton of spices, regulate the intestinal health of pigs, and improve immunity.

(5) The pig house is kept dry: The higher the humidity in the pig house, the colder the pig feels and the pig's skin, respiratory, infectious and parasitic diseases. In order to prevent moisture and leaks, the pigs should be allowed to defecate urine and keep the pig's prone position clean and dry. Some detergent (powder) products can be used to spray the sheds, which can both dry and reduce bacterial growth. Give pigs a comfortable living environment.

Adjust the breeding plan and do a lot of farm management

The problem of sows not estrus and low fertility rates due to high temperatures and disease infections is coming to an end. After autumn, there will be a large number of sows to be bred, and there will be obvious estrus. If uncontrolled breeding, there will be peak calving during the Spring Festival. The emergence of. People frequently flow during the Spring Festival, and people's hearts are unstable. If you add a large amount of workload at the height of the farrowing cycle, common disease epidemics and high mortality rates may occur, and more pigs do not bring in more slaughter results. Therefore, breeding in the autumn should not be excessive and should be carried out in accordance with the normal breeding program so as to avoid undue losses. This requires that the farm be strictly implemented as planned.

Formulate and implement comprehensive disease prevention measures in autumn and winter

In autumn and winter, many diseases are prone to occur. The reasons are as follows: on the one hand, due to the variable temperature and large temperature difference; overcast and rainy weather, and high humidity; the ventilation of the livestock houses is reduced due to the implementation of insulation measures; the microclimate in the livestock houses deteriorates; Mildew occurs more often. On the other hand, the pigs who have just passed the hot weather are still weak, and some pathogenic microorganisms will take advantage of the opportunity to reproduce in large numbers, thus leaving most of the pigs in a sub-healthy state, which can easily lead to the spread of a variety of diseases, such as red piglets, yellow and white piglets. , swine flu, transmissible gastroenteritis, porcine reproductive and respiratory disorders, swine fever, and swine plague.

For the above situation, we suggest to take the following measures:

(1) Improve feed nutrition, strengthen health care; increase energy and supplement nutrition. Based on the basic compound feed, add Flowell Bio-Fukang (for pigs) or Le-Sweetin (specialty for pigs), or add Vivienne 500g/ton to the feed to ease the risk to the herd All kinds of stress, enhance the body resistance to disease.

(2) Strict disinfection management: Prepare a variety of disinfecting equipment, trimming and disinfecting the door, disinfecting the pool and other hardware measures, according to the disinfection procedure, do thorough sterilization every time, and strictly sterilize the passing personnel and vehicles, etc. Members are forbidden to string buildings and must be quarantined after they come back. To cultivate disease-free, we must adhere to the habit of regular disinfection to prevent the occurrence of diseases; at the same time, we must do a good job of driving mosquitoes and flies to prevent the spread of diseases.

(3) Immunization and deworming: Targeted immunization strengthening according to the local epidemic and the status of the farm. Such as the fifth disease, swine fever, pig pseudorabies, swine lung disease, etc. At the same time do a good job in the autumn deworming.

(4) Control of humidity: If there is more rainy weather and the humidity is too high, after the rain stops, you may consider using lime in the field. Disinfect on the one hand and absorb excess moisture on the other hand to reduce the humidity of the livestock house and prevent the growth of bacteria.

In summary, although the cool autumn weather is very suitable for the growth of pigs, due to the numerous factors and the epidemic situation of large-scale pig farms, if you do not do some preventive work in advance, it will probably cause a lot of losses. The above measures hope to provide some help to the farmers.
