Abstract

The Chabro chicken, a crossbred strain derived from Barred Plymouth Rock and Red Cornish breeds, is a hardy, fast-growing bird well-suited for backyard and small-scale poultry production due to its adaptability and natural resistance to predators. The present study investigated the growth patterns of the superficial pectoral muscle in male and female Chabro chickens at 6, 8, and 10 weeks of age. Morphometric parameters, including muscle length, width, thickness, weight, volume, and cross-sectional area, were measured to assess developmental changes. A progressive increase in all muscle dimensions was observed with advancing age. Males generally exhibited higher values than females, although most sex-related differences were not statistically significant. On average, muscle length increased by approximately 11% in both sexes, whereas thickness, volume, and cross-sectional area showed more pronounced growth—particularly in males between 6 and 8 weeks of age. The muscle attained its greatest width in the middle portion, with minor sex-related variations noted at specific ages. In conclusion, the superficial pectoral muscle of Chabro chickens exhibits a consistent pattern of hypertrophic growth with age, with males showing a slightly greater growth potential than females.
