There are morphological and reproductive physiological differences between swamp buffalo (Bubalus carabanensis) and river buffalo (Bubalus bubalis). The development of fetus weight and fetus biometry was reported in river buffalo and other animals but not in swamp buffalo. The aim of this study was to describe the inherent variability in fetus related measurements during swamp buffalo pregnancy. The data is based on measurements of 267 fetuses and 5 new born claves from swamp buffalo. The results show that a significant linear correlation exists between estimated age of fetuses and parameters of fetus sizes. There were correlations between crown-rump length (CRL) and other fetal parameters, as well as between fetus weight and its parameters. In conclusion, our data indicated that the feasibility and value of fetal measures in swamp buffaloes being used for the evaluation of fetal development.
