“Spending more $$$ on Bovine Estrus detection, and still not getting it right”


The biggest concern for breeding farms raising cattle is reproduction. A farm productivity is directly related to the reproduction results. Therefore, efficient estrus detection and timely insemination is vital to successful breeding management.     

The failure of estrus detection incurs an average waiting period of 21 days till the cow enters estrus again. This causes additional feeding costs of USD 7 per day, and USD 150 in total (reference to the Livestock production costs survey 2018). Those farms unable to detect estrus could suffer from the additional burden of feeding, labor, and farm management costs.   

  


“Link between Estrus Detection and Fertility”


Estrus detection in farms heavily rely on the observation of behaviour, such as, mounting, vulva swells, etc., along with other visual aids using color marks and/or other devices. Once ovulatory follicle is ovulated, it lasts 6 to 10 hours from the start of the standing estrus, therefore, the successful estrus detection and insemination is the key to increase fertility.

“Nightly onset of Standing Estrus”

 

Korean Hanwoo breed approaches puberty getting the first standing estrus at the age of 6 to 7 months, weight around 100 to 120 kilograms. A heifer 14 months old and around 280 to 300 kilograms is capable of reproduction(reference to the Korean Livestock Breeding Technology Association). Cows just progressed to the maturing stage tend to have less stable estrus cycle, any attempts to reproduction process to the sexually immature heifer could only reduce the chance of fertility.

The onset of standing estrus is found often at night, mostly from midnight to dawn. The period of standing estrus lasts 18 to 20 hours although there are some variations. It is recommended to carry out artificial insemination within 11 to 14 hours after the onset of estrus to get better results (reference to the Korean Livestock Breeding Technology Association). 



“Getting Data-driven, Entity-specific Estrus Cycle”
 

LiveCare Bio-capsule is inserted orally and placed in rumen. It collects core body temperature and activity level in real time. LiveCare’s sophisticated artificial intelligence (AI) technology can diagnose individual entity using data. This allows the users to monitor their cattle anytime, anywhere through mobile APP and PC. 

Here is the user experience from Chungnam province, Korea. After a normal parturition on June 12th, the cow exhibited estrus on July 16th that lasts till the next day. Afterwards, it was confirmed that the cow re-entered estrus on a regular cycle as of August 7th.  



A regular estrus cycle averages 21 days with some variations in a range from 18 to 24 days depending on the health status of cows. Effective management of estrus cycle improves the productivity, also the overall economic perspectives of the farm by avoiding additional costs of labor and fees on artificial insemination. Farms have manually tracked or used excel spreadsheets to keeping records on the farm activities. Now we have come a long way, we can manage the tasks in a better and smart way. LiveCare uses the scientific analysis methods based on data, and it’s our mission to support the livestock industry to enhance overall productivity through increasing fertility.
