Data were collected from 10 castrated male KNBG. The goats were fed for 90 days under two different feeding systems: high alfalfa diet treatment (KHA; 8:2 alfalfa:concentrate ratio) and low alfalfa diet treatment (KLA, 2:8 ratio). Loin was used for analysis. Numbers (0–15) represent the storage or aging time duration in days. a–c Superscripts within the same column indicate significant differences (p<0.05) between storage days within the same alfalfa level. A,B Superscripts within the same row indicate significant differences (p<0.05) among alfalfa levels on the same storage day. Data from Kim et al. (2022a).
Data were collected from 35 KNBGs (Capra hircus coreanae) categorized into three groups: castrated males (n=12), non-castrated males (n=11), and females (n=12). x,y Mean values with different letters within the same column differ significantly (p<0.05). Data from Aung et al. (2023).
