Feed Intake and Feeding Behaviours
as measured by the GrowSafe System
Background | |
The Animal Behaviour and Feed Efficiency Network is a collaboration of researchers and industry personnel currently working in the area of applied animal behaviour and net feed efficiency. The Network’s objectives are to:
- Develop and standardize hardware and software for measuring individual animal feed intake and behavioural traits using systems that integrate radio frequency (RF) transponders, remote physiological sensors, wireless communication, RF detection and software design (eg., GrowSafe System).
- Establish standards for data collection, conservation, access, analysis, evaluation and improvement, and contribute to the scientific basis for animal science data management.
- Develop new statistical methods for large data set analysis and pattern recognition.
- Provide training opportunities to researchers, industry representatives and technicians to improve their knowledge and application of these novel technologies for their particular needs.
- Review and discuss existing research programs in view of recommending improvements, enhancing co-ordination and reducing unnecessary duplications.

Standards Document
Summarizes feed intake and behaviour definitions, includes standard operating procedures, GrowSafe Software assumptions and a section on calculating daily feed intake. The Standards Document is a living document that can only be altered by members of the Board of Directors (BOD) of the Animal Behaviour and Feed Efficiency Network. Individual members can change the document by submitting a proposal to the committee. The BOD will vote on all proposed changes and approval is based on consensus. If requested changes are approved they will be incorporated into the document with a corresponding updated version number. The document acts as a guideline to all network members to ensure consistency of methodology and data management within the network.
The Standards Document - Feed Intake and Feeding Behaviours as measured by the GrowSafe System is available as a downloadable PDF file - 2,128K. If you have a 28.8K modem, the report will take approximately 10 minutes to download.
Grad Student Projects
Use of machine learning techniques to determine the relationship between weather and feeding behaviour patterns in feedlot cattle. This project will use pattern recognition and feeding behaviour as predictors of sickness/acidosis in cattle. They hope to develop algorithms that will be useful in relating weather, and feeding behaviour to intake. Supervisor, Dr. Karen Schwartzkopf-Genswein, Scientist, Agriculture and Agri-Food Canada – Lethbridge Research Centre
Effect of aggressive interactions on feeding behaviour patterns and performance of feedlot cattle. They plan to investigate the relationship between interactions occurring at the feed bunk, on feeding patterns, performance and morbidity. Supervisor, Dr. Marina Von Keyserlingk, Assistant Professor, Animal Welfare Program, Faculty of Agricultural Sciences, The University of British Columbia.
Development of a non-invasive, early disease detection system for beef cattle. This project will develop a practical, cost effective system for the non-invasive, early detection of disease in beef cattle using infared themography, feeding behavior and the GrowSafe System. Supervisor, Dr. John Basarab, Research Scientist, Alberta Agriculture Food and Rural Development – Lacombe Research Centre.
Development of a mobile system for monitoring ruminal acidosis in cattle. They hope to develop a portable indwelling pH measuring system for dairy cows in loose housing, to aid in investigation of effects of diet and management on acidosis. Supervisor, Dr. Karen Beauchemin, Scientist, Ruminant Nutrition, Agriculture and Agri-Food Canada – Lethbridge Research Centre
