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 ...
Pigs are extensively farmed, and therefore the terminology is well developed: Pig, hog, or swine, the species as a whole, or any member of it. The singular of "swine" is the same as the plural.

By the time the mix-up was discovered a year later, contaminated livestock feed had been sent to hundreds of farms. [5] About 500 contaminated farms were quarantined.

A 23-year-old hiker who survived 13 days lost in the Australian wilderness after stumbling on two granola bars has thanked his rescuers for enduring “tough conditions” to find him.
Prey animals, sheep, goats, pigs and cattle, were progressively domesticated early in the history of agriculture. [3] Pigs were domesticated in the Near East between 8,500 and 8000 BC, [4] sheep and goats in or near the Fertile Crescent about 8,500 BC, [5] and cattle from wild aurochs in the areas of modern Turkey and Pakistan around 8,500 BC.
