A study was undertaken to assess the relationship between variation in udder and teat measurements and milk yield as affected by parity in Jaffarabadi buffaloes. A total of 150 buffaloes selected from private dairy farms located around Hyderabadwere considered for the study. The mean and SE values of udder length (UL), udder width (UW) and udder depth (UD) in buffaloes of different lactations were ranged from 59.86 ± 1.00to 68.51 ± 1.02 cm, 49.17 ± 0.47to 52.38 ± 0.51 cm and 15.24 ± 0.19to 20.06 ± 0.43 cm, respectively. Significantly (P<0.01) positive correlation was observed between udder measurements viz., UL, UW and UD and daily milk yield. The UL, UW and UD in 4th parity were significantly (P<0.05) higher than 1st and 2nd parity but was found comparable with 3rd parity. The mean teat length of left fore, right fore, left hind and right hind teats were 7.69 ± 0.10 cm, 7.79 ± 0.11 cm, 8.63 ± 0.16 cm and 8.67 ± 0.16cm, respectively and teat diameter of left fore, right fore, left hind and right hind teats were 3.05 ± 0.03cm, 3.04 ± 0.03cm, 3.26 ± 0.03cm and 3.31 ± 0.04cm, respectively. The average teat length and teat diameter recorded for different parities were 8.20 ± 0.12cm and 3.17 ± 0.03cm, respectively. A positive correlation existed between average daily milk yield and various teat measurements like teat length, teat diameter and distance between fore and hind teats. However, the correlation was significant (P<0.05) only between milk yield and teat diameter. The study concludes that there is an increase in udder and teat measurements with increase in lactation number, specifically UW and teat diameter, due to their significant positive correlation with milk yield could be considered as criteria for selection of Jaffarabadi buffaloes for higher milk yield.
