Can we unravel the complexity of enteric methane production in pigs?

PhD defence, Friday 1 March 2024, Elvira Sattarova

Elvira Sattarova

During her PhD studies, Elvira Sattarova investigated how nutritional and animal factors influence methane production in pigs and developed a mathematical model for predicting methane production from growing-finishing pigs. Methane, a potent greenhouse gas, is formed in pigs during the fermentation of nutrients in their hindgut. Elvira investigated the effect of substrate availability for microbial fermentation in the hindgut on methane production and how it is affected by the physiological stage of pigs, dietary fibre inclusion level and fibre type. The new research findings contribute to a better understanding of hindgut fermentation in pigs and how nutritional and animal factors influence enteric methane production. Moreover, these findings provide a basis for improving the model for predicting methane production from growing-finishing pigs based on nutrient intake, feed composition and animal characteristics.

The PhD study was completed at the Department of Animal and Veterinary Sciences, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
