Estimation of liveweight from chest girth in pure and crossbred west African goats

Linear and geometric regression equations were used to estimate liveweight from chest girth in 78 West African Dwarf and 73 Sahel x West African Dwarf goats. The coefficients of determination (R2) ranged from 0.87 to 0.92 and 0.97 to 0.99 for linear and geometric equations respectively. There were n...

More Information
Summary:Linear and geometric regression equations were used to estimate liveweight from chest girth in 78 West African Dwarf and 73 Sahel x West African Dwarf goats. The coefficients of determination (R2) ranged from 0.87 to 0.92 and 0.97 to 0.99 for linear and geometric equations respectively. There were no significant breed or sex differences in the R2 values of the equations. The geometric equations estimated liveweight with a high degree of reliability regardless of girth size whilst the linear equations yielded very low and frequently negative liveweight estimates where girth measurements were below 30 centimetres.
