Research reveals vitamin A injection enhances calf growth and muscle gene expression during development.

This study aims to evaluate the impact of vitamin A injection on calf performance and muscle transcriptomics during the cow-calf phase.
Pregnant cows were assigned to control, VA injection in cows, or VA injection in calves groups.
Calves were weighed at 60 days and again at weaning.
Carcass ultrasound and muscle biopsies were performed at weaning.
Gene expression levels were analyzed using RT-qPCR.
Male calves in the VAcow group had significantly higher average daily gains compared to Control males and VA-treated females.
Weaning body weights were greater in VAcalf and VAcow males compared to Control males.
Specific gene expressions (RARA, MYF5, CEBPA) were higher in Control and VAcow calves than in VAcalf calves.
PAX7 expression was significantly higher in VAcow males compared to all other groups.

Oliveira et al. (2026) studied this question.
