It clips to the tail three to four days before her due date, measures the tail movements that come with labour contractions, and alerts you by SMS, app notification, and email so you can be in the shed when the calf arrives. HereBro lists it under [AI Livestock & Yield](https://herebro.com/listing-category/agriculture-farming/ai-livestock-yield/). ## How does the Moocall calving sensor work? The sensor is a tail-mounted motion sensor. When a cow gets a contraction her tail moves in a specific way, and that movement is what the device measures: around 600 data points every second. When the pattern crosses a threshold the first high-activity alert fires, and a second alert follows if the movements continue. Moocall reports the device can reduce calf mortality associated with difficult calvings by up to 50 percent. ## How does the sensor alert me? An SMS goes to up to two phones, the free BreedManager app sends a push notification and a loud “Moo” sound, and email covers a third channel. The sensor runs on the mobile network with a built-in SIM, so it needs no Wi-Fi and no base station. That suits rural sheds where connectivity is patchy. ## How many cows does one sensor cover? Moocall recommends one sensor per 30 to 40 cow herd, depending on your calving spread. The sensor is moved from cow to cow as they come close to calving: a tight calving window can often be managed with one or two units. One charge lasts more than four weeks. ## What does the Moocall calving sensor cost? Moocall’s help center lists standard reference prices of 267 euro ex VAT in Europe, 239 pounds ex VAT in the UK, and 329 dollars in the US. The sensor ships with 12 months of data, software, updates, and support from activation, plus a 12-month warranty on the electronics. After the first year an annual service subscription applies: 135 euro in Europe, 120 pounds in the UK, or 150 dollars in the US, with a 10 percent discount on the service fee for additional sensors. In Ireland the purchase terms list 329 euro up front and 166 euro every 12 months. Prices vary by region and promotion, so check the vendor’s shop for your market. ## What is the BreedManager app? BreedManager is Moocall’s free herd management app on iOS and Android. It tracks due dates, calving events, and breeding history with smart lists that split the herd into in-calf, cycling, and inseminated groups, and it works without a sensor. With a sensor registered it delivers the calving push notifications and alert history. Moocall lists 20,000-plus customers across 65-plus countries, and says it has monitored over 1.5 million calvings. ## What are the limitations? The sensor has to be fitted three to four days before the due date and managed between cows, which suits block-calving herds better than year-round calving. Alerts travel over the mobile network, so coverage depends on signal in your shed and paddocks. The standard warranty is 12 months on the electronics, extendable for a fee at the year-one renewal, and the 30-day money-back guarantee covers the purchase. ## How does it compare with other livestock tools? Calving cameras cover a fixed view of the shed; a tail sensor travels with the cow. For a wider toolkit, [Cowlar’s smart collar](https://herebro.com/listing/cowlar-smart-collar/) tracks herd health and activity. On the crop side, [Arable’s Mark 3](https://herebro.com/listing/arable-mark-3/) monitors the field rather than the animal. ## Listing information - **Category:** AI Livestock & Yield - **Feature:** Mobile App - **Price:** From 267 euro (ex VAT) - **Website:** https://www.moocall.com ## Frequently asked questions ### How much does it cost?
