Four calves without signs of haemoglobinuria served as controls. The blood smears from three of the eight calves contained piroplasms for Theileria annulata. Irrespective of the presence of piroplasms in their blood smears, the calves with haemoglobinuria had signi¢cantly (p50.01) lower haemoglobin concentrations (Hb) and packed cell volumes (PCV). The lipid peroxide level in the erythrocytes, but not in the plasma, of calves with red urine was signi¢cantly (p50.05) higher than that for the controls. It is concluded that haemoglobinuria, irrespective of the presence of piroplasms in blood smears, is associated with oxidative stress to erythrocytes and peroxidation of polyunsaturated fatty acids of cell membrane.

Methods Four spotted deer (2 years of age, 68.3 kg average body weight) and six sheep (1.5 years of age, 18.0 kg average body weight) were fed on the above two fodder types as sole feed. Nutrient digestibility and evaluations were made through two digestion studies that ended with each feeding period.

The calves in group 1 (G1) received a maintenance diet of concentrate (C) and wheat straw (WS) as the sole roughage; in group 2 (G2), C, WS and oak leaves (OL) at a ratio of 31:39:30 on dry matter (DM) basis and in group 3 (G3), C, WS and OL at a ratio of 33:45:22. The feeding lasted for 4 weeks and included a metabolism trial of 6 days duration. The DMI (kg/day) increased (41 and 38% in G2 and G3, respectively) with supplementation of oak leaves, being higher in G2 (2.90) followed by G3 (2.82) and G1 (2.05). Digestibility (%) of DM, organic matter and neutral detergent fiber was higher in G2 (51.5, 55.8, 49.0) compared to G1 (43.9, 49.3, 43.7) and G3 (45.4, 50.1, 44.0) contributing to higher ME intake (17%). Increased N utilization efficiency (20.6, 67.7 and 55.1% in G1, G2 and G3, respectively) and microbial protein production (180, 209, 194 g/day) coupled with a decrease in plasma urea level (about 25%) was observed in oak leaf supplemented groups. Supplementation of WS/OL ratio of 44:56 enhanced DMI, digestibility, efficiency of N utilization and body weight gain compared with a WS/OL ratio of 100/0.

The mean microbial population in different cropping systems in decreasing order is legume > cereal > sugarcane > cotton. Significantly higher (P < 0.05) microbial population has been recorded in high management (6.20 log 10 cfu g -1 ) and irrigated agrosystems (6.33 log 10 cfu g -1 ) compared to low management (6.12 log 10 cfu g -1 ) and rainfed agrosystems (6.17 log 10 cfu g -1 ). The pooled analysis of data inclusive of bioclimates, cropping systems, land use, management practices, and edaphic factors indicates that microbial population is positively influenced by clay, fine clay, water content, electrical conductivity, organic carbon, cation exchange capacity and base saturation, whereas bulk density, pH, calcium carbonate and exchangeable magnesium percentage have a negative effect on the microbial population.
