[QUOTE="foxbox, post: 4082850, member: 220"] Depends on the bolus as there are two types, one with pH (very expensive at present) and one without (still expensive but much more realistic). I'm not sure where they are priced at present as they've been put on farm as part of a trial and I'm not going to guess where they may end up being priced either in case I upset anyone! To be honest though for the calving alerts alone I think they offer real potential, have a look at this. [ATTACH=full]556198[/ATTACH] The cow was housed and you can see her rumen temperature is fairly stable whilst pregnant at around 40C; the drops are when she drinks. Just before she calves her body temperature drops significantly enough for the bolus to spot it (see the alert labelled fertility). She calved where the second alert is shown (the heart - indicating a rapid rise in activity) which started at 5am (so 15 hrs warning of calving in this case) which is her getting up and cleaning the calf up, mothering it etc. She was penned up with the calf shortly afterwards (so the activity drops again due to the size of the pen) and then turned out to grass with her calf the following day at 10am when the activity spikes again. After that her routine starts to adjust to being at grass. We're still in the early stages of the trial but later on it may be best if I start a thread on it. [/QUOTE]
