Autumn is the golden age of raising pigs. The cool climate and suitable humidity are most suitable for pig growth and development. Therefore, pig farmers should seize the key period of autumn, improve the technical level of pig raising, and achieve the purpose of increasing production and increasing efficiency. Huinong.com compiled a series of precautions for raising pigs in autumn, hoping to help our vast number of pig farmers and obtain higher breeding benefits in the golden autumn.
First, the use of new corn
In the fall, due to the high price of Chen corn and the difficulty in purchasing in some areas, the use of new corn has become an urgent choice for people to solve. However, although the new corn has been harvested, it has not reached full maturity. The digestion and absorption of some nutrients is worse than that of Chen corn. This shows that when using new corn in autumn and winter, the feed intake of the outer pigs is increasing, but growing. The speed is not fast, and there are often strange phenomena of skinny hair.
It should also be noted that the new corn is too moist and prone to mold during long-term storage. Therefore, it is recommended that the pig farm store some high-quality aged corn in advance, and there is a transitional stage when using new corn. Even if it is unable to store a large amount of new corn, it must take into account the situation that the new corn has high water and low digestibility, and reduce the proportion of protein feed in the feed. Or add high-energy feeds such as oils and fats to maintain a balance of energy and protein ratios.
Second, transitional breeding
Every year in July and August, during the high temperature and high humidity season, the number of sows in the sows is significantly reduced. In addition, the quality of the boar semen is poor, and the breeding rate is reduced. By September, there will be a large number of empty sows to be matched.
As the temperature drops, and some pig farms take aphrodisiac measures, the number of sows in the sows increases rapidly. At this time, the number of breeding is likely to be too large. The sows in this stage are usually in the coldest month of the year. Larvae, together with the factors of the Spring Festival, will cause serious shortages of the littering house and related personnel. Because of the lack of care, the litter house is prone to various problems and the piglet mortality rate is very high.
Therefore, in September and October, it is necessary to pay attention to the planned breeding to prevent the inconvenience caused by too much sows.
Third, the stress of pigs from hot to cold
The weather is getting cold, which is good for big pigs, but it is not good for piglets, because big pigs are afraid of hot pigs, especially piglets that are weaned and nursery to fattening tend to have more problems due to improper response. Kind of problem. So you must pay attention to the following issues:
1. The transfer of high-temperature dry pig houses to low-temperature moist pig houses: This is a problem that is easily overlooked by people, but the harm to pigs is great.
When the piglets are weaned, they will be transferred from the farrowing house to the nursery. At this time, the nursery is often cleaned and disinfected, and the pig house is highly humid (the day is shorter, the night is growing, the air circulation is blocked, etc. It is difficult to dry.) If there is no heating facility, there will often be insufficient effective temperature, which will increase the possibility of diarrhea.
The nursery pigs transfer to the fattening house, often from the net bed to the ground; there will be several large gaps, one is to prevent the temperature from being low, the pig house is closed more tightly, for more than 20 kilograms and density For large nursery pigs, the temperature inside the house will be very high, much higher than the newly transferred fattening house.
At the same time, the nursery is often a net bed, and the finishing pig is often a cement floor. The effective temperature of the pig on the concrete floor is much lower than that of the net bed. For example, the effective temperature of the net bed is lowered by 2 ° C, and the effective temperature of the dry cement floor. Will reduce 5 ° C, while the effective temperature of the wet concrete floor will be reduced by 10 ° C.
In this way, from the nursery to the fattening house, the temperature drops drastically, and the problem is easy to occur when the piglet can withstand the limit. Therefore, we must pay attention to the difference between the environmental conditions of the two pig houses when transferring the group. The use of heating facilities in advance can reduce the hazard; if the heating is not possible, the dry pad or bedding of the piglets can also slow down the influence of the temperature difference.
2, the temperature difference between day and night increases the impact on pigs: after the arrival of autumn, the cold wind at night can not be ignored, especially piglets raised on the net bed, must pay attention to the cold wind blowing from below; but often because of too much emphasis on insulation The pig house is closed too tightly and the air quality deteriorates. Therefore, we must take both into consideration.
The following methods are available for reference:
First, pay attention to the wind direction every day, and prevent cold wind from blowing piglets at night;
The second is to set a windshield at the bottom of the door. In the case where the upper part continues to be ventilated, the lower part can prevent the blowing of cold air;
The third is to promptly clean up the feces or dirt in the house where it is possible to disperse the dirty gas, and keep the house clean and hygienic.
3. Test run of heating facilities in advance: Many pig farms use heating facilities in winter, which is undoubtedly beneficial for raising pigs; but the phenomenon of “normally not burning incense, temporarily holding Buddha feet†often occurs in production, and the weather is getting cold. Think of heating, not a lack of fuel, or heating facilities are not easy to use, busy to turn around but no good results.
Therefore, the heating facilities must be repaired and commissioned in advance of the cold, and everything will be ready for use.
4. Pay attention to the weather changes every day: climate change often has aura. The weather forecast provides us with too much convenience. As long as we pay attention to the weather changes every day, and promptly remind the production personnel when the climate changes suddenly, the problem will be greatly reduced. Many pig farms fill in the weather changes on a blackboard in a conspicuous area, which is also very helpful for production.
4. Proactive vaccine prevention for infectious gastroenteritis
Autumn is the most prone season for infectious gastroenteritis, and the diseased pigs often start with the fattening stage. However, because of the need for post-sea acupoint injection during the injection of infectious gastroenteritis, it is very difficult to vaccinate the fattening pigs; if the vaccination is carried out when the pig weight is still small, the difficulty is much less.
In the September and October, the piglets were fat pigs to be released before and after New Year's Day. If these pigs have been vaccinated, the possibility of pig disease is small. Therefore, it is recommended that the area of ​​infectious gastroenteritis often occurs in the prevention of vaccines in September and October, which can prevent the occurrence of the disease, and the workload is not large, and it is easy for employees to accept.
Fifth, pay attention to personnel coordination
During the autumn harvest period, it is inevitable that the leave of the guardian is unavoidable. It is not advisable to strictly prohibit the ban. This will hurt the feelings of the staff and the manager; some farms’ experience can be used for reference. Their method is to set up a mutual aid group. For leave, the work of the leave is replaced by other members of the group.
The advantage of this is that it does not affect the relationship between the manager and the employee, and the coordination of the personnel in the group has little effect on the work, and the management personnel are no longer guilty of the employee's leave.
There will be a lot of problems during the autumn harvest, and each farm will have different conditions; but as long as we are thinking about pigs at the time of autumn harvest, more difficulties will pass.
