Abstract

Abstract
In order to evaluate type traits, records of 148 and 336 heads Khuzestani and Azari buffaloes were used, respectively. The animals was evaluated for height-at-withers (HAW), chest depth (CD), body length (BL), chest circumference (CC), hip width (HIW), pin width (PW), hip to pin length (HP). The means and standard deviations of mentioned traits for Khuzestani breed were 145.25±6.63, 78.27±5.43, 140.5±8.39, 208.87±13.75, 57±4.44, 25.29±3.03 and 44±2.97 centimeter, and for Azeri breed were 138.93±6.39, 76.4±5.61, 136.22±10.05, 184±13.66, 54.96±4.85, 26.43±3.94 and 43.8±3.44 centimeter respectively. The breed had significant effect on HAW, CC and HIW (P<0.001) traits, and Khuzestani buffaloes had higher biometric dimensions than Azeri buffaloes. The parity had significant effect on all studied traits expect CC (P<0.001). In both of studied breeds, heifers had the lowest biometric dimensions than other groups, and the differences between them become higher by increasing parity number. The province, as a factor related to the climatic changes and breeding condition, had significant effect on all studied traits expect CC and HP (P<0.001). The lowest body dimensions were measured in Azeri buffaloes reared at Guilan province, and the highest body dimensions were measured in Khuzestani buffaloes reared at Khuzestan and Kermanshah provinces.
