Transcriptome profiles of the skeletal muscle of mature cows during feed restriction and realimentation.

ABSTRACT:

Objective

Realimentation can compensate for weight loss from poor-quality feedstuffs or drought. Mature cows fluctuate in body weight throughout the year due to nutrient availability. The objective of this study was to determine whether cows that differ in weight gain during realimentation also differ in the abundance of transcripts for enzymes associated with energy utilization in skeletal muscle. Mature cows were subjected to feed restriction followed by ad libitum feed. Skeletal muscle transcriptome expression differences during the two feeding periods were determined from cows with greater (n = 6) and less (n = 6) weight gain during the ad libitum feeding period.

Results

A total of 567 differentially expressed genes (408 up- and 159 down-regulated) were identified for th
