Pig food waste and its management

Abstract

In the recent years, the very issue of food waste management has become a global concern and an alarming topic. As per the Food and Agriculture Organization (FAO), approximately one-third of the total global food production is wasted annually. The amount of food waste which is generated in the common households is very high, with studies and statistics showing that up to 50% of household waste comprises of food items. Because of the disposal of food waste, it contributes significantly to many such environmental phenomena like greenhouse gas emissions and others, which in turn, contributes to climate change which automatically affects us .Pigs comprise a group of domesticated mammalian species classified within the Suidae family. They are very intelligent and very social animals also known for their pink skin and curly tails. They are mostly raised for their meat, but they are also used for other products such as leather, lard, and pharmaceuticals The feed which is being fed to pigs should be free from any kind of bacterial and fungal contamination and should not affect the health of the animal. Using food waste (FW) as animal feed offers a solution that addresses issues related to FW management and food security, while also reducing the need for conventional feed production, which is resource-intensive and has environmental implications.  In this review we will be discussing about the pig food waste management and what are the different ways to preserve and manage the food waste.
