Title: Genetic and Phenotypic Parameter Estimates of Morphometric Traits in Sudan Desert Goats
Author: Yousif, Ibrahim; Fadlelmoula, Abdelaziz; Ismail, Ahmed
Abstract: This study describes phenotypic and genetic potential of morphometric traits of Sudan desert goats. A LSML (Least Square and Maximum Likelihood) program package was used to analyze the data. Linear body measurements (Height at wither, body length, heart girth and paunch circumference) of 343 male and female goats aged from birth to 12th month were estimated. Average ranges were 30.04-52.10, 25.45-46.17, 30.25-63.78 and 30.86-67.90 cm for height at wither, body length, heart girth and paunch circumference respectively. Means of the traits measured were significantly (P<0.01) different among ages. Heritability estimates for linear body measurements ranged 0.10-0.48. The average range of genetic correlations among body measurements from sire component was 0.36–0.96, and that from dam component was 0.30–0.99. Results showed an average range of phenotypic correlations of 0.16-0.70 among body measurements at various ages. Sire and dam showed significant effects on body measurements at age from birth to twelve month. Based on the magnitude of the genetic correlation coefficients, height at wither and heart girth could be used for predicting live weight of the animal.
