Transcriptome analysis reveals the regulatory mechanism of myofiber development in male and female black Muscovy duck at different ages.

ABSTRACT:

Introduction

Sexual dimorphism in Muscovy ducks results in substantial differences in muscle development potential between males and females, leading to significant variations in growth rates and body weights throughout their development.

Methods

This study aimed to investigate the regulatory mechanisms underlying the differences in muscle development between genders in black Muscovy ducks, we analyzed the phenotypic characteristics and transcriptome profiles of breast muscles in male and female black Muscovy ducks at different developmental stages (postnatal days 28, 42, and 70).

Results

In the analysis of tissue physical morphology, the results showed that females exhibit larger myofiber diameters and lower myofiber densities compared to males at postnatal day 42 (<
