    A study was conducted to investigate the effect of different levels of herbal supplements on productive performance of Sahiwal cows. Fifteen healthy Sahiwal cows of similar age and body weight were allocated to three experimental groups namely T0, T1 and T2 with five animals in each group. T0 was fed with balance ration (concentrate mixture, para grass and paddy straw) as per requirement, T1 group was supplemented with 25 gms of fenugreek seed (Trigonella foenum graecum) along with balance ration and T2 was fed with 50gms of fenugreek seeds along with balance ration. It was observed that overall mean daily dry matter intake (kg/day) in T0, T1 and T2 were 10.01±0.02, 10.24±0.03 and 10.22±0.08 respectively. Analysis of data on dry matter intake showed no significant difference (p>0.05) between control and treatment groups respectively. Furthermore, non-significant differences was found in DMI/100kg body weight between the control and treatment groups. The average digestibility coefficient (%) of DM in T0, T1 and T2 groups was: 71.12±0.27, 73.58±0.26 and 74.72±0.22); 72.97±0.08, 73.78±0.06 and 75.34±0.09 for organic matter (OM); 67.89±0.11, 65.54±0.05 and 68.48±0.07 for crude protein (CP); 70.70±0.05, 70.98±0.09 and 72.06±0.08 for ether extract (EE); 48.80±0.37, 50.04±0.29 and 56.24±0.28 for crude fibre (CF) and 77.14±0.15, 77.35±0.04 and 78.13±0.09 for nitrogen free extract (NFE) respectively. Analysis of the data revealed significantly (P<0.01) higher digestibility of the nutrients in herbal supplement (fenugreek seeds) fed treatment groups than control group. The overall mean for milk yield (kg)in the experimental cows were 7.00±0.05, 7.56±0.08 and 7.99±0.10 respectively in T0(control), T1 and T2 groups. Feeding of fenugreek found to have positive effect in the treatment groups. Highly significant differences in milk yield was found (p<0.01) between treatment groups. Also, Milk efficiency was significantly higher (p<0.01) in treatment groups compared to control. However, there was no significant effect of fenugreek seeds in the duration of peak milk and lactational milk yield of the experimental cows. Milk composition like total fat(%), solid-not-fat(%), lactose(%), protein(%), ash(%), specific gravity was within the normal range. However highly significant difference (p<0.01) was observed in fat, SNF, lactose, protein and ash content. The blood constituents like blood glucose and total serum protein were within the normal value among the treatment groups and showed no significant differences (p>0.05) between the treatment groups. Daily cost of feeding per cow per day were Rs. 182.20, Rs. 192.20 and Rs. 195 in T0(control), T1 and T2 respectively. Cost of feeding per kg milk yield was Rs. 26.02, Rs. 25.15 and Rs. 24.40 in T0, T1 and T2 respectively. The benefit cost ratio was found to be higher in treatment groups than in control group. Based on the results of the present study it could be concluded that feeding of fenugreek seed at the level of 50gms daily along with the normal diet increased performance in terms of milk yield, milk composition and digestibility of nutrients. However, there was no significant effect in duration of peak milk yield, lactational milk yield and blood constituents.
