The study was aimed at providing a complete picture of milk yield and composition during different stages of lactation in Tellicherry does. A total of 40 Tellicherry does aged between 2 – 2 ½ years in 2nd parity were selected for the study. The lactation period wasdivided into three stages namely early, mid and late lactation stages and data on milk yield, and milk composition such as milk fat, SNF and specific gravity of milk during lactation were collected. The milk yield did not vary with lactation stages. The total lactation milkyield was 33.29±0.45 kg and the milk yield/doe/day was 0.36±0.04 kg. The average fat, SNF and specific gravity during lactation were 3.47±0.17%, 8.74±0.11% and 1.032±0.00 respectively. The fat percentage was significantly (P<0.01) higher during mid (3.61±0.19%)and late lactation (4.21±0.22%) than that of early lactation (2.60±0.12%). The SNF percentage and specific gravity were found to be significantly (P<0.01) higher during early lactation (9.24±0.17%; 1.035±0.00) followed by mid (8.76±0.06%; 1.031±0.00) and late lactation (8.23±0.06%; 1.029±0.00).
