Norwell Dairy Systems adds AfiAct II to their Afimilk line

Published on 03 October 2014

Norwell Dairy Systems Ltd. is pleased to announce that AfiAct II has been added to the full line of Afimilk products it offers in Ontario.

Afimilk is, for the first time, improving the fertility of tied cows by enabling their automatic heat detection with AfiAct II Stanchion.



AfiAct II Stanchion incorporates long-range data collection and leg-mounted behavior monitoring tags (AfiTag II) throughout the stanchion barn. It sends heat alerts as breeding lists to users' computers and cell phones.

The system’s heat indicator analysis delivers accurate, high-performance heat detection in tie stalls. The company claims that the system can increase pregnancy rates by 6 percent and 9 percent compared to visual observation, and can reduce yearly open days by 20 to 40 per cow, compared to other methods.

Statistics from users show that the system doubles the number of confirmed heat events. Almost no cows were missed by AfiAct II, but detected by the operator (visual inspection), while a significant number of animals were bred solely following system detection.

Until now, technology-driven solutions have failed to address dairy herds in stanchion barns, where detecting estrus and determining insemination timing are problematic. Herds in freestalls and open lots benefit from automated heat detection, which increases their fertility traits and improves herd profitability.

In contrast, farmers of tied cows have relied on visual detection of heats or synchronization protocols. This often results in open days and longer lactation intervals, preventing the herd from reaching full profitability.  PD
