For conservation and utilization of livestock local breeds is necessary to
characterize and quantify both productive system and genetic potential of the breed.
Profitability of farm production is always studied under economic parameters, but hardly
under productive. A study was carried out to determine factors affecting live weight (LW) and
body condition score (BCS), both at partum and at weaning, of the Ojinegra sheep breed
under productive conditions. LW and BCS at partum, at weaning and its variation were
influenced by the age of the animal, by the season of parturition, and by the farm (p<=0.05).
BCS was also affected by birth rate, but only at partum and the variation of BCS along
lactation (p<0.05). The farm itself was a determinant factor, representing up to 48% of
variability in some parameters. Variation among farms might be explained both by
management particularities and/or herd genetic heterogeneity.
