Last Updated: 2024/11/06, The high temperature environment from June to September every year disrupts the secretion of sex hormones in pigs, disrupts the normal mechanism of oestrus, and makes the symptoms of estrus not obvious or non-estrous; high temperature makes pigs focus their energy on resisting high temperature stress, and accordingly weakens the functions of other aspects. this will lead to lack of milk and slow growth due to lack of nutrition for lactating sows and fat pigs that need to eat a lot. High temperature will make it difficult for boar testis to dissipate heat, intensify sperm metabolism and shorten life span, thus reducing sperm motility and even death; high temperature will also make newly fertilized sperm fertilized.

The high temperature environment from June to September every year makes the pig sex hormone secretion disorder, disturbs the normal oestrus mechanism, makes the oestrus symptom not obvious or not oestrus; the high temperature makes the pig mainly devote energy to resisting the high temperature stress, correspondingly weakens the function of other aspects, which will cause the phenomenon of less milk and slow growth due to insufficient nutrition for lactating sows and fat pigs that need to eat a lot; High temperature will make boar testis heat dissipation difficult, sperm metabolism intensified, life shortened, resulting in reduced sperm motility or even dead sperm; high temperature will also make just fertilized eggs increased death and increased difficulty of fertilized egg implantation, thus reducing the fertility rate of summer breeding.
