Embodiment 1

[0022] Embodiment 1, reference figure 1 , a sow perinatal body temperature assessment method, comprising:

[0023] Step 1, obtaining the back surface temperature, eye surface temperature, ear surface temperature, vulva surface temperature and udder surface temperature of the sow;

[0024] Step 2, substituting the back surface temperature, eye surface temperature, ear surface temperature, vulva surface temperature and udder surface temperature into the evaluation mathematical model to obtain the body temperature of the sow;

[0025] Among them, the evaluation mathematical model is:

[0026] Tt=(0.15*Tb+0.1*Ty+0.18*Te+0.2*Tw+0.37*Tr)*1.062;

[0027] Tt is the sow’s body temperature, Tb is the sow’s back surface temperature, Ty is the sow’s eye surface temperature, Te is the sow’s ear surface temperature, Tw is the sow’s vulva surface temperature, and Tr is is the udder surface temperature of the sow.

[0028] The body temperature of 83 perinatal sows was evaluated by the eva...

Abstract

The invention discloses a method for evaluating body temperature of sow at a perinatal period and a system thereof. The method includes: obtaining the back surface temperature of the sow, the surface temperature of the eye, the surface temperature of the ear, the temperature of the vulva surface, and the surface temperature of the breast, and performing substitute of the back surface temperature, the eye surface temperature, the ear surface temperature, the vulvar surface temperature, and the breast surface temperature into an evaluation mathematical model to obtain the sow's body temperature. By measuring the surface temperature of each part of the sow, a temperature value is obtained by the above measurement, and a body temperature value of the sow is obtained through the evaluating the evaluation mathematical model. The system includes a temperature acquisition device and a body temperature calculation device. Through a non-invasive measurement method, the sow's stress response cannot be caused under the premise of correctly reflecting the sow body temperature. The system is conducive to pig farming operations.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a method and system for evaluating body temperature of sows during perinatal period. Background technique [0002] Body temperature is considered to be an important indicator reflecting the degree of heat stress and health of animals. The existing method for measuring the body temperature of sows is to insert a surface thermometer into the anus, so that the surface thermometer can obtain the value of the body temperature of the sow. However, this method will cause great harm to sows in the peripartum period. Among them, the sow perinatal period refers to the period from 7 days before calving to 7 days after calving. Due to the physiological characteristics of sows, this intrusive body temperature measurement method can easily cause stress reactions in sows and affect the health of sows. Therefore, there is an urgent need in the industry for a method that can accurately ref...
