Abstract
Poultry farming is the domestication of birds, such as chickens and ducks, for the purposes of acquiring meat, feathers, and eggs. This industry is prevalent worldwide, as 36.9% of the world's meat production involved poultry products in 2018 (Mcgauran et al., 2021). There are two types of chickens that are raised in poultry farming: broiler and layer chickens. Broiler chickens are raised for meat while layer hens are raised to produce eggs (THL, 2020). Together, 66 billion chickens (134 tonnes) are processed annually worldwide. Unfortunately, one of the major issues with poultry production is the 68 million tonnes of waste produced yearly, which causes deleterious effects on humans, animals, and the environment (Mcgauran et al., 2021).
