[Objectives] This study was conducted to analyze and study the growth and development of muscle fibers at different stages, so as to provide a theoretical basis for subsequent research on developmental biology and nutritional regulation. [Methods] The body weights of black goat lambs in groups at different month age (0 - 6 months old) were recorded, and the diameter, area and number of muscle fibers were measured by tissue section and hematoxylin-eosin staining. The curves of body weight and muscle fiber growth and development of black goat lambs were drawn. [Results] The black goat lambs maintained a high absolute growth intensity of 2. 95 - 4. 35 kg/30 d throughout the rearing cycle, and the body weight continued to increase significantly, while the relative growth coefficient decreased from 93.05% at the age of 30 d to 13. 83 % at the age of 180 d. The diameter and area of muscle fibers in black goat lambs showed obvious " three-stage" growth and development characteristics, and showed different trends of gender advantages in different stages. [Conclusion] This study will help to further optimize the key supporting technologies for production and promote the diversified and comprehensive development of the mutton sheep industry in Sichuan Province.
