A feeding management experiment was conducted to determine the effect of green maize and anjan tree leaves on the performance of crossbred heifers. Fifteen crossbred heifers of 7 to 26 months age and 79 kg average initial body weight were divided into three equal groups (T1) having green maize (Zea mays) + jowar straw+ concentrate, (T2) 40:60 anjan tree leaves (Hardwickia binata Roxb.) + green maize + jowar straw + concentrate and (T3) 60:40 anjan tree leaves + green maize + jowar straw + concentrate respectively. The trial was conducted with the help of factorial randomized block design . In blood metabolic profile blood glucose, serum total cholesterol and serum triglyceride were conducted. Blood glucose level decreased, from 42.85 to 42.40 mg/dl on feeding T1 control diet. While levels showed an increase from 37.62 to 46.25 and 39.14 to 48.20 mg/dl in heifers on feeding T2 and T3 rations over 17 week's period respectively. On the other hand, serum total cholesterol and serum triglyceride levels exhibited improvement irrespective of treatments in all heifers. The increase was from 75.64 to 81.84, 75.89 to 83.18 and 75.20 to 82.25 mg/dl in serum total cholesterol levels under T1, T2 and T3 group heifers. While, the increase in serum triglyceride values were from 5.46 to 5.77, 5.78 to 6.32 and 6.15 to 6.75 mg/dl in T1, T2 and T3 heifers respectively.
