Abstract

The present study was designed to observe the effect of season and stage of lactation on milk components of Purnathadi buffaloes. Total 346 milk samples were collected, from three different seasons (winter, summer and rainy) and stage of lactation (early, mid and late) for the study. Overall milk fat, protein, lactose, solid not fat (SNF) and total solids (TS) were observed as 8.44±0.07, 3.99±0.02, 3.96±0.02, 8.78±0.04, and 17.23±0.08% respectively. There was significantly higher fat and total solids percent during winter (9.01±0.23 and 17.62±0.26% respectively) and lower during summer (8.25±0.14 and 16.73±0.14% respectively) season, but milk SNF percent was significantly higher during rainy (9.00±0.04%) and lower during summer (8.48±0.05%). Stage of lactation had also significant effect on milk components; milk fat, protein, SNF, and TS percent increased significantly with the advancement of lactation stage, whereas milk lactose was nonsignificant. Milk fat during early, mid and late lactation was 7.43±0.10, 8.40±0.07 and 8.79±0.12%; protein was 3.83±0.06, 3.94±0.02 and 4.06±0.02%; SNF was 8.36±0.14, 8.70±0.04 and 8.96±0.05% and TS was 15.61±0.17, 17.10±0.08 and 17.75±0.12%, respectively. Thus, results of the present investigation indicated that season and stage of lactation affect certain milk components in Purnathadi buffaloes and could be minimized by better farm management practices.

泌乳季节和阶段对普那沙迪水牛乳汁成分的影响

本研究旨在观察泌乳期和泌乳期对普那塔迪水牛乳成分的影响。研究共采集了3个不同季节(冬、夏、雨季)和泌乳期(早、中、晚)的346份乳样。乳脂、蛋白质、乳糖、非固体脂肪(SNF)和总固形物(TS)含量分别为8.44±0.07、3.99±0.02、3.96±0.02、8.78±0.04和17.23±0.08%。脂肪和总固形物率冬季显著高于夏季(分别为9.01±0.23和17.62±0.26%)，夏季显著低于冬季(分别为8.25±0.14和16.73±0.14%)，而牛奶SNF率雨季显著高于夏季(9.00±0.04%)，夏季显著低于夏季(8.48±0.05%)。泌乳期对乳成分也有显著影响;乳脂、蛋白质、SNF和TS百分比随着泌乳期的推进而显著增加，而乳糖则不显著。泌乳早、中、后期乳脂含量分别为7.43±0.10、8.40±0.07、8.79±0.12%;蛋白分别为3.83±0.06%、3.94±0.02和4.06±0.02%;SNF分别为8.36±0.14、8.70±0.04和8.96±0.05%，TS分别为15.61±0.17、17.10±0.08和17.75±0.12%。因此，本调查结果表明，哺乳季节和阶段会影响Purnathadi水牛的某些乳成分，可以通过更好的农场管理措施将其最小化。
