The oestrus Law of female Fox
The estrus of the female fox shows that the vulva is covered by pubic hair during the resting period, which is not easy to find; during estrus, the pubic hair is separated due to vaginal swelling. The estrus period of female fox is short, mating is difficult, and the timing of adaptation is also difficult to grasp, especially the empty rate of silver-black fox is higher. In order to improve the reproduction rate, it is necessary to master the oestrus law of female foxes and carry out mating or artificial insemination at the right time. The estrus of female foxes can be divided into three stages: the first stage: the clitoris begins to swell, clitoris enlarges, tends to be heterosexual and sexually excited, and generally continues.

High temperature causes heat stress and affects the physique of pigs.
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.
