The details of pig farm winter

    Winter in the north is extremely cold, and the south is extremely cold. The cold air is one after another, and the cold stress brought to the herd is even more serious. I believe pig farms are well prepared for how to spend the winter. However, many pig farms only supplement some basic vaccines such as foot-and-mouth disease, epidemic diarrhea, etc. in the fall-winter period, add health medicines, and close the pigsty. I hope that this will be a smooth winter. However, it is precisely because of some negligence in details that the pigs may become unstable under the effect of cold stress. So, what are the details that farmers should pay attention to when cold air arrives?

    First, the insulation box and heat preservation lamp in the delivery room

    In winter, the delivery room is usually closed tighter, so it is not a big problem to maintain the temperature inside 23 ° C ~ 25 ° C. However, because of the fear of the piglets being frozen, the lamp in the incubator is usually on for 24 hours. Thought it was foolproof. But be aware that pigs will use actions to tell you if they live in a comfortable or uncomfortable environment. If the piglets go to the farrowing bed and get together next to the sow to sleep, it may indicate that the lamp is not warm enough. If the piglets are sleeping in the farrowing bed and are unwilling to enter the incubator, or lie in the incubator far from the lamp, the temperature of the incubator is too high. Conversely, if the piglets are crowded to sleep under the insulation lamp, it means that the incubator is not warm enough. The temperature of the heat preservation lamp cannot be adjusted, but the height of the heat preservation lamp above the ground can be adjusted to change the somatosensory temperature of the piglets.

    Feeding of sows in the delivery room

    In order to allow sows to eat more feed on the farrowing bed, many pig farms also feed wet sows in winter. The water is cold in winter, so use warm water when mixing sows. Feeding sows in the delivery room is based on sows' full meals. How to judge whether a sow is full can be explained by many performances. First of all, an unsatisfied sow will keep standing after feeding and make a sound by making a sound or making a sound. The sow may not be full, but she lay down and rested due to lack of energy. At this time, the sow should be photographed in time to allow her to continue to feed. Sows that have been emptied in the trough should be fed in time until there is still remaining in the trough. The sow will breastfeed as soon as it is full. If it is not full, the sow will usually lie on its stomach and collect its breasts under the belly. Feeding sows in the delivery room freely, with feed in the trough for 24 hours, is actually not a good way to feed. Even in winter, the temperature of the delivery room is prone to mold.

    Ventilation of premises

    One of the most difficult aspects of a winter pig farm is the relationship between ventilation and thermal insulation. In winter, the pig farm hopes to not freeze the pigs, but ignores the fact that the pigs may be stuffy. It may also be a matter of right and wrong. I feel that a flu or blue ear is more important than ammonia.

    You know, pigs are animals that are not afraid of heat or cold. Fat is so thick that it is still resistant to cold. And cold stress is usually caused by sudden cooling. If the sow is kept in a constant temperature of about 18 ° C, she will be very happy. But piglets can't be so low, so the incubator is especially important. Ventilation is also necessary because the harmful gases in the house are too heavy, which in addition to directly affecting the respiratory mucosal system, can also cause problems such as decreased feed intake, decreased immunity, and increased harmful bacteria. In fact, many times the instability of winter herds is related to fresh air.

    Of course, ventilation can not be freely ventilated, it should be ventilated in the sunny afternoon, when the temperature is highest in the day. In addition, the ventilation holes should be as high as possible, and should not be blown directly onto the pigs.

    Fourth, the use of heating tools

    There are various tools for heating pig farms in winter, mainly divided into two types, wind heating and plumbing. Air heaters are mainly heaters, which consume a lot of power. There are also coal-fired stoves in the north, which are prone to produce toxic gases such as carbon monoxide, which affects herd breathing. Plumbing is mainly based on floor heating. In the past, coal-fired boilers were basically converted to electricity, which consumes more electricity. The electric heating plate for piglets belongs to local heating.

    Heating facilities use more and more electricity, so the safety of electricity has become the focus. Equipment and facilities in the pighouse are improperly maintained and prone to aging, so the annual inspection and update must not be neglected.

    Five, dry and humidity adjustment of pigsty

    In the north, autumn and winter are dry and dusty, which irritates pigs' mucous membranes. Herds, especially fattening herds, are prone to coughing and sneezing, and pathogens are more likely to spread on dust. Therefore, the humidity of the piggery cannot be greatly reduced for the purpose of keeping warm, which leads to the reduction of feed compensation and even the misjudgment of diseases. In the south, there are many rains and winters, especially in March, and there are many humid weather, which will cause the pig's physical temperature to be low, and may cause a higher degree of mold mildew, more bacteria breed, and increase the infection pressure.

    The epidemic prevention in winter is not just to seal the pigsty sternly, add medicine to the feed, and worry about replenishing the vaccine in advance. In order for pigs to survive the winter, you also need to understand the needs of the pigs and experience the living environment of the pigs. Putting some important details into place can really raise pigs.
