Dairy buffaloes are reared in the field with lack of practice of proper feeding, exposing them to postconception decline in milk yield (MY). A series of studies were conducted to investigate the issue. Data of three large farms comprising 30912 MY records were analyzed. Post-conception (PC) MY decline was investigated at a private dairy herd on 23 pregnant and 17 non–pregnant buffaloes. Role of milk progesterone levels (MPL) with the PC decline in MY was investigated in 40 adult lactating dairy buffaloes belonging to three groups: i) PRT (pregnantration traditional); ii) PRS (pregnant-ration supplemented); iii) NPRT (non-pregnant- ration traditional). Reduction in MY was effected by location, conception season, lactation week, gestation month and parity. Gestation month contributed to the reduction in milk yield by 1.4%. Third parity showed the least reduction. The predicted reduction was highest (-4.48 L/wk) in high than moderate and low yielders. In the high yielders the cost of this supplementation was ten times less than the loss due to MY decline. It may be concluded that the onset of pregnancy in dairy buffaloes results in drastic decline in MY at an early stage. Concentrates supplementation induced a raise in progesterone levels which in turn, affected the milk yield negatively (r=-0.61, P<0.001).
