Extract

Most sheep production systems under arid or semiarid conditions are dependent on the ability of animal to retain and movilize body fat.

The sucess of body condition score (BCS) method (Russel et al., 1969) and live body weight (LBW) as mesures of body reserves is in function of body fat depots distribution, and the sheep genotype could determine this distribution (Taylor et al., 1989).

The aim of this work is to predict body fat depots of adult Churra ewes, from BCS and/or LBW.

A total of 36 adult Churra ewes, with a range of body condition score between 1.25 and 4.00 and live body weight between 30.3 and 52.6 kg were used.

At slaugther, internal fat depots (IF; omental:OF, mesenteric:MF and perirenal:PF) were removed and weighed. Chemical fat of carcass (CF) and non-carcass (NCF) were also estimated.
