!Jal11Oil 4lX lactation records of 130 Nili-Ravi buffaloes maintained during 1978-93 at the Livestock Experiment Station. University 01 Agriculture. Faisulabad were analysed to estimate rcpeatahility 01 some productive and reproductive traits. Lactation lenuth averaged .127.945 ± 3.335 days, 305-day milk yield 1773090 ± 20.167 kg. total milk yield 190fdl53 ± 24.557 kg. peak yi~ld 244.018 ± 2.545 kg and dry period 164.237 ± 4.886 days. Repeatabilitics of these 5 traits were calculated as 0.322 ± 0.054, 0303 ± 0.054.0.344 ± 0.053, 0.303 ± 0.054 and 0.106 + 0.062 respectively. '.
