Beef Cattle Rationing Model

The Beef Cattle Rationing model was developed using data from beef production experiments undertaken at AFBI Hillsborough between 1992 and 1999. The main role of the model is to predict the performance of beef cattle offered grass silage/concentrate-based diets using the chemical composition and/or intake characteristics of the grass silage. The model provides information on the performance of a wide range of animals across different breeds, genders and conditions which can be used as a tool by animal nutritionists and farmers to optimise systems of beef production. The model provides two estimation options:
  1. The number of weeks to achieve a specified final live weight
  2. The final liveweight achieved after a specified feeding period
The model should be used with silage analysis results obtained from the Hillsborough Feeding Information System (HFIS).

Disclaimer: These formulations and feeding recommendations are produced as a guide only, based on the information available at the time and do not constitute a guarantee that the predicted levels of performance will be achieved in practice. Many other factors may have an over-riding effect on animal performance such as the management of the cattle, the environment and disease.
