New heat detector for sows by Rotecna

New heat detector for sows by Rotecna

04th January 2022 - News

Given the increase in the number of farms that implement the cover and release system, and in anticipation of the approval of new legislation that prohibits the use of cages after insemination, Rotecna launches an automatic heat detector.

Detecting the heat of sows in time is vital to improving fertility, prolificacy and reducing unproductive days. Farmers invest a lot of time in breeding tasks, which must be performed several times a day to detect heat at the right time, and which are exceptionally complicated when sows are grouped in parks rather than in individual cages.

Rotecna has developed a new electronic heat detector that solves this problem effectively, allowing detection and marking the sows that are ready to be inseminated at the right time reliably and automatically.

Rotecna’s new heat detector, which can supplement the electronic individual feeding system for pregnant sows in the Dositronic G group, consists of a stainless steel structure with an inspection window, an antenna that detects electronic ear tags and a marking system that singles out the animal inside.

The Rotecna heat detector is installed in the pen where the sows are on the side of the antenna that identifies the electronic ear tag that each animal carries. In contrast, on the other side, there is a boar that attracts the sows that are in heat.


A simple but highly effective procedure characterises Rotecna’s new heat detector since it identifies the sows in heat according to the duration and number of visits they make to the boar through the inspection window. Sows in heat visit the male more frequently and for longer; it marks them when the system detects these patterns.
