Abstract

The determination of energy content of carcass and body of domestic animals by direct method is very intensive labour and high cost. The aim of current study was to evaluate the relationship between body weight (BW) and body condition score (BCS) with energy content of muscular and adipose tissues of adult Pelibuey ewe. The data of 22 adult non-pregnant, non-lactating ewes with BW of 35.63 ± 5.03 kg and BCS of 2.47±0.55 were used. The correlation coefficients (r) of BCS between muscle energy (ME), fat energy (FE) and total energy (TE) were all significant (P< 001) with values of 0.64, 0.66 and 0.69 respectively. For BW between ME, FE and TE were all significant (P< 0001) with values of 0.90, 0.76 and 0.89 respectively. The regression equations had high determination coefficients (r2) that ranged from 0.87 and 0.94 when BCS was used as predictor, while using the BW the r2 ranged from 0.59 and 0.83. The use of BCS and BW in sheep Pelibuey provides a good estimate of the ME, TE, FE of the carcass.
