A comparative analysis of carcass traits and meat quality between Tibetan sheep and their three-way crossbred sheep.

ABSTRACT:

Introduction

To improve meat yield and nutritional quality of Tibetan sheep of the Qinghai-Tibet Plateau, Australian White and Small-tailed Han rams were introduced to crossbred with Tibetan sheep (Oura-type, O) ewes which possessed genetic homogeneity. The aim of this study was to compare growth conformation, meat quality, and further identified related candidate genes between Tibetan sheep and their three-way crossbreds (25% Australian White × 25% Small-tailed Han × 50% Oura-type Tibetan, AHO).

Methods

Fifteen 5.5-month-old male lambs (8 O and 7 AHO crossbred) were raised for 5.5 months. We compared body conformation, carcass traits, meat quality (pH, color, cooking loss), nutrient composition (amino acids, fatty acids, ribonucleotides) in longissimus thoracis et lumbor
