| description | Detection of estrus is an essential factor as a method of successful breeding in
the sow. As increasing the adaption of the information and communication
technology (ICT) into swine industry, this study focuses on a possibility and
quantification of standing time, vulva and body temperature as methods of estrus
detection, comparing each time and temperature in estrus and non-estrus period,
and analyzing each success rate of new and existing methods. Ultrasonic sensor
array and digital infrared thermography were used to evaluate whether new
methods such as standing time and number, and vulva and skin temperature can be
replaced, or these methods can be quantifiable in estrus period. Ultrasonic
sensor array was installed beside the stall and digital infrared thermography
was placed in the rear of sow to collect the dates of sow in estrus and
non-estrus period. This study showed total standing time, number and number over
10 minutes, and vulva temperature of the sow in estrus period were increased
(p < 0.05) compared with those of sow in non-estrus
period, respectively. Detection of estrus using standing time and vulva
temperature tended (p = 0.06) to increase the success
rate when artificial insemination (AI) was performed. In conclusion, standing
time and vulva temperature increased when estrus happened. Success rate of AI of
sow using these methods showed an increasing trend. Therefore, existing method
using the naked eye can be replaced to new method such as vulvar temperature and
standing time when detecting the estrus. |
