Essential oils have long been used in perfumes, skincare, and aromatherapy.
Researcher Ehsan Parand at Wageningen Livestock Research is exploring how aromatic plant extracts can help reduce greenhouse-gas emissions from livestock.
Methane from ruminant animals, such as cows and sheep, is a significant contributor to agricultural greenhouse-gas emissions, making it a target for reduction in global climate strategies.
Nutritional innovations, including adding essential oils to livestock feed, are expected to play a key role in achieving future emission goals.
Aromatic plant extracts might be added to livestock feed to help mitigate methane emissions.
