Abstract:

Wenling grass chicken is a high-quality local breed in Zhejiang Province, which has the characteristics of good meat quality and good taste. In this study, a total of 15 male and female 300-day-old Wenling grass chickens were randomly selected to measure body size and slaughter performance, and to do correlation analysis. The results showed that Wenling grass chicken had larger breast depth, compact body shape and better slaughter performance. Tibial circumference was highly correlated with slaughter indexes. Except abdominal fat weight, there was a significant correlation between body size and slaughter indexes.

Key words: Wenling grass chicken, body size, slaughter performance, correlation analysis
