Abstract:
An investigation was carried out named correlation of teat biometry with milk yield and composition in Jaffarabadi buffaloes. A total of 40 for experimental Jaffarabadi buffaloes from Cattle Breeding Farm, Junagadh Agricultural University, Junagadh, Gujarat were selected. Milk yield per milking was recorded for each animal during evening milking. Milk composition was also evaluated from the sample milk collected from each animal during the experiment period. Duration of experiment was 3 months. All the teat measurements were taken prior to milking at monthly intervals. All milk samples were analyzed at fortnightly intervals. The result showed that among different teat shapes, conical teats was the most common followed by funnel, cylindrical, pear and bottle shaped teats with 39.17 percent, 34.17 percent, 14.16 percent, 7.5 percent and 5 percent, respectively. The overall mean teat lengths of fore left, fore right, rear left and rear right were 8.29±0.19, 7.75±0.18, 8.53±0.22 and 7.88±0.19 cm, respectively among various teat shapes. The overall mean teat diameters of fore left, fore right, rear left and rear right were 3.30±0.06, 3.20±0.07, 3.27±0.06 and 3.07±0.06 cm, respectively among various teat shapes. The overall mean distance between fore teats, between rear teats and between fore and rear teats among various teat shapes 12.39±0.28, 6.58±0.17, 8.74±1.08 and 7.54±0.18 cm, respectively. The mean values of milk yield per milking among various teat shapes were 4.10±0.20, 4.47±0.21, 4.56±0.35, 4.02±0.68 and 3.08±0.34 kg/milking in funnel, conical, cylindrical, bottle and pear shaped teats, respectively. Distance between rear rear teats was positively and significantly (p<0.05) correlated with milk yield but highly significantly (p<0.01) correlated with solid-not-fat, lactose, salt and protein percent and density (kg/m³). However, distance between fore rear right was positively and highly significantly (p<0.05) correlated with solid not fat, lactose, salt and protein percent and density (kg/m³). Therefore, buffaloes with cylindrical shaped teats are taken into consideration as a selection tool for efficient milk production.
