Abstract
The objective of this study was to determine the relationship between body weight (BW) and body condition score (BCS) in non-pregnant, non-lactating Katahdin ewes under tropical conditions. Body weight and BCS were measured in 110 Katahdin ewes aged 2.5 years with mean BW of 43.18 ±6.73 kg and mean BCS of 2.38 ±0.82. Relationships were analyzed using correlation and linear regression. Body weight and BCS showed a strong positive correlation (r = 0.90; P < 0.001). The linear regression equation was BW = 25.66 (±0.84) + 7.34 (±0.33) × BCS (R² = 0.81, MSE = 8.39, RSD = 2.89, n = 110). These results indicate that 7.34 ±0.33 kg of BW are required for each unit change in BCS in Katahdin ewes managed under humid tropical conditions.
