Piglets: do a good job in disease prevention caused by temperature changes

Problems prone to weaning piglets in autumn

The diarrhea rate of piglets increased in autumn. From hot summer to cool autumn, the temperature drops greatly, and the temperature difference between day and night is up to 10 ℃, which is easy to cause diarrhea and affect the growth of weaned piglets. The thermoregulation ability of piglets during weaning is not perfect, and the comfortable ambient temperature of 26 ℃ ~ 28 ℃ is needed.

Respiratory diseases occur seriously. In autumn, ventilation is very important in order to adjust the temperature and humidity of the pigsty. On the one hand, if the ventilation is not smooth, the harmful gases in the pigsty, such as ammonia and hydrogen sulfide, not only smell bad, but also have strong irritation. It is highly corrosive to pig eyes and respiratory mucosa. Pigs living in this environment are much more likely to develop respiratory diseases. On the other hand, if the ventilation is too large, the piggery entering the cold air can easily cause respiratory diseases such as piglet cough. The suitable humidity for weaned piglets is 65%-70%. Too damp can cause dermatitis, scabies and other diseases, too dry can cause dust increase, induce asthma, atrophic rhinitis and other diseases.

Feed mildew affects the performance of piglets. There are many Rain Water in autumn, and the stored feed is easy to mildew. If farmers make their own ingredients, they must frequently check the quality of corn and fishmeal and deal with the problems as soon as possible. Seriously moldy ones are not allowed to feed and strictly prevent poisoning.

In addition, pigs eat too late before and after dark, eat too much, sleep on the spot after eating, and the swollen stomach contents are invaded by cold at night, resulting in abnormal fermentation of stomach contents that will cause fever and hunger strike. In the evening, pigs should be fed regularly and quantitatively, pigs should have sufficient time to digest after feeding, and appropriate exercise or feeding amount should be reduced when feeding is late.

Feeding management and preventive measures

First of all, temperature is the most important, and heating facilities should be prepared before there is no temperature change. As long as the temperature changes suddenly, we can strengthen the work of heat preservation at night, take precautions and minimize the losses caused by natural factors. Repair the pigsty and block the air leakage in the barn to prevent the cold wind from attacking.

Coordination of heat preservation and ventilation. The best way to reduce the humidity and improve the air of the pig house is ventilation, and the most effective measure of ventilation is to open a vent on the ceiling, so that a large amount of moisture and bad gases can be discharged from the house as soon as possible without opening the doors and windows. and change into fresh air. But ventilation should be controlled, more ventilation in sunny and warm days, less ventilation in cloudy and cold days, so as to coordinate ventilation and heat preservation.

The prevention of respiratory diseases mainly considers the improvement of the environment and the necessary drug prevention. How to make the transition from free large window ventilation to weak ventilation in closed houses requires paying attention to climate change all the time and adjusting the air volume through the window switch in time.

Transmissible gastroenteritis and epidemic diarrhea are common infectious diseases in autumn. If piglets are vaccinated two months in advance, the antibodies in their bodies can still resist the threat of pathogens when they grow up, which will greatly reduce the harm of the disease.

Before weaning, feed was added as early as possible to improve the immunity of piglets. It is suggested that each piglet should be fed at least 600 grams of feed before weaning, so as to strengthen the gastrointestinal digestive system function of piglets before weaning, so as to adapt to feed, especially plant feed, after weaning. Establish immune tolerance to feed crude protein and reduce dietary antigen allergic reaction. The use of microecological agents in feed can improve gastrointestinal environment, prevent piglet diarrhea, and improve piglet immunity and disease resistance.
