Rumen pH Bolus
l Invented in 2003 in UK l First publication: Mottram et al., 2008 l Low pH means high digestible energy
- high energy ? - High digestibility ? - High sugar grasses ?
l Improves milk yields AND cow health l Commercialised by 5 companies worldwide l Www.ecow.co.uk l Revising the diagnosis of SARA and ketosis
Rumen pH Bolus
l Inserted by mouth l Retained in Re>culo-‐rumen l Data downloaded by radio l Uploaded to internet l Analysed and interpreted
A high yielding herd
Low pH but regular feed pattern with cows not eating at night
Same herd after a feed change
AEer a feed change, pH is higher and cows eat more at night
Temperature Measurement
Each drop in temperature is caused by a drinking event, five a day is good, something was wrong here, it seems the cows did not have close access to water at grass.
The Challenges
Soil moisture management Improves crop growth Reduces N2O emission Drainage and irrigation control
Soil nutrient & pH measurement Crop management
Water N measurement Control pollution Reduce algal bloom
History
Smartdust A US DARPA project for military applications
Wireless Sensor Network for soil water management
Next Stage
Biogradeable wireless nodes for soil and water Multiple sensors per node Better modelling to interpret data [email protected] Sensors from www.ecow.co.uk
