Transcriptome analysis reveals age-specific growth characteristics in the rumen of Hanwoo (Korean native cattle) steers.

ABSTRACT:

Background

Hanwoo cattle are a Korean breed renowned for their cultural significance and high-quality beef, characterized by low cholesterol and a high unsaturated fat ratio. Their growth is divided into a growing stage focused on development and a fattening stage for marbling. Proper feed management, considering genetic and environmental factors, is vital for maximizing growth potential. The rumen plays a crucial role in digestion and gene expression regulation, with rumen fermentation being central to nutrient absorption and cattle health. In this study, we conduct a transcriptome analysis of the rumen at eight timepoints. Our goal is to identify genetic factors that influence the growth of Hanwoo steers to enhance our understanding of the rumen's functions during Hanwoo growth.<
