Evaluacion genetica de llamas Q’ara por el metodo de estandares zoometricos en el departamento de Oruro, Bolivia

Abstract

The current study was carried out in the Oruro department in Bolivia in form of thirteen Regional Shows of South American domestic camelids. The objective was to evaluate the genetic value of male and female llamas using a zoometric standards method. The samples consisted of 1687 Q’ara llamas, divided into the following categories: A (milk teeth), B (2 teeth), C (4 teeth) and D (full set). The following measurements were carried out: live weight, body length, withers height, thoracic perimeter, rump wideness; from these results the selection genetic values were obtained using a modified Neale equation. The results were: 115.60 kg live weight, 107.3 cm withers height, 110.66 cm body length, 118.48 cm thoracic perimeter and 27.87 cm for rump wideness. The genetic values were: 44.69% for group A, 39.75% for group B, 1.48% for group C and 12.03% for the S value (super). The genetic values obtained by age and sex were: 12% for S the value in females from group A and 12% in males from group D. The winning animals in shows were compared with genetic values with a 50% match.
