Genetic parameters for birth weight (BW), weaning weight (WW), pre-weaning average daily gain (ADG1), 18-months weight (18 MW) and post-weaning average daily gain (ADG2) were estimated using single-trait and multi-trait analyses. Data consisted of 2257 records for the Botswana Composite and 5923 records for the Tswana collected between the period of 1988 and 2006. The individual animal model (AM) and animal maternal model (AMM) were fitted in both analyses.
