Genetic and non-genetic factors influencing production in two boer goats studs

Abstract: 
The effect of genetic and environmental factors on weaning and post-weaning traits of boer goats was studied using 3233 records collected from 1998 to 2008. Least square analysis was used for estimation of environmental effects. Genetic parameters were estimated using ASREML. All fixed effects were significant (P<0.05) for both traits. The direct heritability estimates varied from 0.24 for weaning weight to 0.31 for postweaning weight. The corresponding maternal permanent environment due to the dam was 0.11 and 0.44 , respectively. The maternal heritability (0.03) for weaning weight was lower than its corresponding direct heritability.
L’effet des facteurs génétiques et environnementaux sur les caractéristiques de sevrage et de post-sevrage des chèvres de Boer a été étudié en utilisant 3233 enregistrements collectés de 1998 à 2008. L’analyse du moindre carré a été employée pour l’évaluation des effets sur l’environnement. Des paramètres génétiques ont été estimés en utilisant ASREML. Tous les effets fixés étaient significatifs (P<0.05) pour les deux caractéristiques. Les évaluations directes d’héritabilité ont changé de 0.24 pour le poids de sevrage à 0.31 pour le poids de post-sevrage. L’environnement permanent maternel correspondant dû à la mère était 0.11 et 0.44, respectivement. L’héritabilité maternelle (0.03) pour le poids de sevrage était inférieure à son héritabilité directe correspondante.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Animal Science"
