The strain-wise and parity-wise biometry of udder, biometry of teat, different shapes of udder and teats, lactation milk yield and correlations were studied in present study. The overall mean of udder length, udder width and udder depth were found to be 41.476 ± 0.3570, 37.773 ± 0.4770 and 15.238 ± 0.1070 cm, respectively. The overall mean of fore teat length, rear teat length, fore teat diameter and rear teat diameter were found to be 3.968 ± 0.0790, 3.505 ± 0.0750, 2.029 ± 0.0130 and 1.930 ± 0.0120 cm, respectively. There was no significant effect of strain on any of udder and teat parameters. However, significant difference was observed in parity on udder and teat biometry. The overall frequencies of bowl, goaty, pendulous and round shapes udder were 49.61, 14.06, 33.20 and 3.12, per cent, respectively. Hence, bowl-shaped udder found to be predominantly. The overall frequencies of bottle, cylindrical, funnel and pear shapes udder were 15.62, 42.96, 32.81 and 8.60, per cent, respectively. Therefore, cylindrical shaped teat found predominantly. The overall mean of lactation milk yield found to be 1173 ± 33.868 kg. There was no significant effect of strain and parity on lactation milk yield. The correlation studies showed that all udder and teat measurements had significant and low to moderate correlation with LMY. These findings suggested that the udder and teat traits correlations should be an important criterion for selection of high yielding Deoni cattleEnglishThesis
