How to prevent swine influenza in pigs raised in autumn?

    Autumn has arrived, and the weather has turned cooler. The temperature difference between day and night has grown larger. Farmers have both joys and worries: the joy is that when the weather turns cool, pigs grow faster and the feed-to-meat ratio improves; the worry is that the large day-night temperature difference makes pigs prone to various diseases.

    —In this season, the main fear is that growing and finishing pigs will be affected by the temperature difference and come down with swine influenza and coughing. For piglets, the fear is epidemic diarrhea.

    But do not panic. Doing the following three things will get you through a crisp, pleasant autumn season.

    First, always choose high-quality feed to ensure the pigs' nutrition reaches a relatively high level, and strictly prohibit the inclusion of moldy ingredients. This is because mycotoxins can suppress pigs' immunity. In addition, routine vaccination work must also be done properly. For example, if the swine pasteurellosis vaccine has been given properly, then even if the pigs contract influenza, pasteurellosis will not occur, and the losses caused will not be too great; if swine pasteurellosis has not been immunized against, then there is a high probability of secondary pasteurellosis, causing huge losses.

    Second, do a good job of preventing drafts in the pens. Generally, after 8 p.m. the shed cloth on the north side should be lowered, and then hung back up by 8 a.m. the next day. In this way, the pigs will not catch cold and cough from the cold, damp night air.

    Third, do a good job of the pigs' health care. At this time, pigs at all stages should be given a course of health care focused on the respiratory tract, for example florfenicol, amoxicillin, and Banqing granules, to keep the pigs growing healthily.
