A study was undertaken to know the effect of udder and teat shapes, parity and lactation stage on milkability and milk flow traits and their relationship with milk yield in Jaffarabadi buffaloes. A total of 150 animals from private farms located around Hyderabadwere selectedand grouped according to udder and teat shapes, parity (1st to 4th lactation) and stage of lactation (early, mid and late).Among milkability and milk flow traits, average milk let down time, milking time, stripping time and total milking time, stripping yield and average milk flow rate (AMFR) recorded in Jaffarabadi buffaloes under hand milking were 1.54 ± 0.01 min, 3.49 ± 0.04 min, 1.28 ± 0.01 min, 6.31 ± 0.05 min, 0.19 ± 0.001 kg and 0.65 ± 0.01 (kg/min), respectively. The AMFR in buffaloes with bowl shaped udders was highest (P<0.05) followed by globular, pendulous and goaty shapes and buffaloes with bottle shaped teats was highest(P<0.05) followed by cylindrical, funnel, pear and conical shaped teats.The AMFR was significantly (P<0.05) high in 3rd parity (0.67 ± 0.01) and low in 1st parity (0.60 ± 0.01) buffaloes and significantly (P<0.05) higher AMFR was recorded during early (0.66± 0.01 kg/min) and mid (0.64 ± 0.01 kg/min) compared with late (0.63 ± 0.01 kg/min) stages of lactation. Positive and highly significant (P<0.01) correlation was observed between average daily milk yield (ADMY)with milking time (r=0.523), total milking time (r=0.489) and AMFR (r=0.624) and significant correlation (P<0.05) with stripping time (r=0.188) and stripping yield (r=0.188).The total milking time and stripping yield had significant (P<0.01) positive correlation but total milking time was negatively correlated with AMFR (r=-0.366, P<0.01). The study concludes that,higher AMFR and higher ADMY were found in buffaloes with bowl shaped udders. Therefore, while selecting buffaloes for milk production, bowl shaped udder should be taken into consideration.
