Mixed farming systems involves livestock keeping integrated with other agricultural activities. These systems are similar to small-scale systems, but tend to be in a more rural setting, given the need for larger tracts of land for crop production. As with small-scale livestock production, access to formal markets is critical. [citation needed]
The development of quantitative methods for livestock production includes mathematical modelling based in plant-herbivore or predator-prey models to forecast and optimise meat production. An example is the Predator-Prey Grassland Livestock Model (PPGL) [7] to address the dynamics of the combined grass-animals system as a predator-prey dynamical ...

Many systems, especially for electronic records, require documents to be formally declared as a record so they can be managed. Once declared, a record cannot be changed and can ...
The NLIS RFID system was introduced in New South Wales on 1 July 2004 and replaced the previous tail tag system for cattle. The approved devices used are the commonly used ear tags or alternatively a rumen bolus. [8] Similar systems exist in other countries such as the National Animal Identification System in the United States, the British ...
