In Indore district of Madhya Pradesh haemoglobinuria is a common problem in buffaloes fed on leguminous straws (gram/masoor) especially during the mid to advanced stage of pregnancy under field conditions. To find out the nutritional causes behind this problem, 60 advanced pregnant buffaloes were selected randomly from villages in and around Mhow tehsil. These animals were divided into two groups with 30 in each, (i) a wheat-straw fed group (WSFG), 30 (Avg. b wt. 538.96+-7.25 kg) and (ii) a gram-straw fed group (GSFG), 30 (Avg. b wt. 535.28+-7.01 kg). Average daily feed intake of each animal was recorded and proximate principles, major minerals (Ca and P) and carotene in available feed stuffs were determined to find out nutrient availability. Deficiency of various nutrients was calculated by comparing with the standard requirements. DCP, TDN and carotene were calculated from reported values. The average daily availabilities of DM, DCP, TDN, Ca, P and carotene were 7.84+-0.08 kg, 184.50+-4.78 g, 3.21+-0.04 kg, 18.27+-0.23 g, 4.91+-0.07 g and 49.68+-0.23 mg, respectively in WSFG. While, in buffaloes of GSFG, the average daily availabilities of DM, DCP, TDN, Ca, P and carotene were 7.74+-0.09 kg, 372.53+-4.22 g, 3.25+-0.04 kg, 118.51+-1.20 g, 3.07+-0.03 g and 48.72+-0.49 mg, respectively. Results indicated shortage of DCP (60 and 20 percent), TDN (38 and 38 percent), P (80 and 87 percent) and carotene (53 and 54 percent) in the WSFG and the GSFG, respectively. Ca supply was in deficit (41 percent) in the WSFG while it was in excess (282 percent) in the GSFG. It was concluded that there was shortage of almost all nutrients in both the groups but very low P intake (13 percent of required) with adverse Ca:P intake ratio (39:1) may be the probable cause of haemoglobinuria in buffaloes fed on gram straw.
