One of the challenges currently experienced in the agricultural environment is determining the optimal age for harvesting pigs while maximising profitability. The harvesting age selection policy affects the carcass weight and the meat quality of harvested animals and, therefore, the income generated from these harvesting activities. This decision also influences the total cost of managing an animal. Various factors influence the optimal age for harvesting pigs, including (but not limited to) genetics, feed, health, care, and climate. All of these factors form a unique scenario for every pig farm and have an impact on the decision-making process. In this study, a mathematical programming model is developed and proposed to assist the farmer in selecting an optimal age to harvest pigs so that, by considering all these abovementioned factors, they can maximise their profitability. The mathematical programming model is verified and validated, and then recommendations for future research are offered.
