SUMMARY

An analysis of six year data (1976-1981) on birth, 3-month, 6-month and weaning weights of Malaysian swamp buffaloes were collected and analysed. Year had a significant effect on all the traits studied. Sex and year X sex interaction had no influence on these traits. The mean birth, 3-month, 6-month and weaning of females and males were 29.4 ± 2.0 vs 30.9 ± 2.0 kg, 91.6 ± 25.4 vs 93.1 ± 22.3 kg, 135.8 ± 18.0 vs 141.3 ± 13.0 kg, and 156.0 ± 37.5 kg vs 157.1 ± 30.9 k g respectively. The combined weights of both the sexes in these traits were 30.3 ± 5.9 kg, 92.3 ± 23.9 kg ,139.2 ± 23.0 kg and 156.5 ± 38.0 kg respectively.
