<![CDATA[Background: Birth weight and weaning weight are important indicators for assessing the early growth performance of calves and supporting beef cattle breeding selection programs. Brahman and Ongole Grade (PO) cattle are two breeds raised at BPTU-HPT Sembawa, yet studies directly comparing their performance within a single study remain limited. Objective: This study aimed to examine and evaluate the differences in birth weight and weaning weight of Brahman and PO calves at BPTU-HPT Sembawa. Method: This study used 200 recorded data consisting of 100 birth weight and 100 weaning weight records (50 Brahman and 50 PO each, comprising 25 males and 25 females). Data were analyzed descriptively and tested using an independent-samples t-test at a 5% significance level, preceded by normality and homogeneity tests. Results: The average birth weight of Brahman (26.22 ± 4.59 kg) and PO (26.10 ± 4.21 kg) calves did not differ significantly (P>0.05), both overall and by sex (males: P=0.374; females: P=0.239). The average weaning weight of Brahman (124.56 ± 26.50 kg) and PO (127.18 ± 24.00 kg) calves also did not differ significantly (P>0.05), both overall (P=0.606) and by sex (males: P=0.126; females: P=0.500). Conclusion: There were no significant differences in birth weight or weaning weight between Brahman and PO cattle at BPTU-HPT Sembawa. The similarity in the Cow-Calf Operation (CCO) rearing system, feed management, and rearing environment is presumed to be the factor causing the relatively similar performance of both breeds.]]>
