The On-Farm Feed Advisor (OFA) is a mobile-based application developed to assist agricultural extension staff and agents in providing tailored nutritional advice to dairy cattle and buffalo farmers. It addresses the issue of over- or under-feeding livestock, which occurs when farmers rely solely on available agricultural by-products and purchased concentrates with minimal understanding of their exact nutritional value. By matching feed choices to an animal's specific physiological needs, the tool eliminates nutritional gaps, maximizes nutrient efficiency, and significantly lowers unnecessary feeding costs. The tool mainly relies on two databases: the nutritional requirements of animals (as per Indian Council of Agricultural Research [ICAR] standards) and the nutritional quality of locally available feeds.
Widely implemented across South Asia, with primary focus areas in India (specifically supported by localized initiatives like the Himmotthan Society in hilly/rural regions, with additional field use in Karnataka, Maharashtra, and Tamil Nadu states) and Nepal (integrated into dairy and livestock feeding platforms).
Evidence from field implementations shows that substituting arbitrary feeding habits with balanced, optimized local ingredients prevents resource wastage and drives down feed-related expenses.
Positive Field Feedback: The On-farm Feed Advisor has been used in different projects in Karnataka, Maharashtra, and Tamil Nadu states and is receiving highly encouraging responses from the field staff.
Distributed entirely digitally via the Google Play Store and Apple App Store, drastically lowering rollout overhead.
User-Editable Constraints: A main advantage is that the end user can edit the nutritional database as feed prices may vary seasonally (users must ensure that the entered data are accurate).
