摘要：Fifteen lactating buffaloes aged 4-6 years, 4 weeks before calving were divided into five feeding treatments, 3 animals each. Medicinal plant seeds were added to basic diet at levels of 200 g fenugreek seeds (T1), 50 g caraway (T2), 50 g black seeds (T3) and 100 g lepidium sativum (T4) were fed for 12 weeks of lactation. Dry matter intake was slightly (p>0.05) increased in T1 than the other groups. Feeding herbs significantly (p<0.05) increased nutrient digestibility (DM, OM, CF and NFE) and significantly (p<0.01) increased digestibility co-efficient of CP and EE compared with control. Milk yield and 4% FCM were significantly (p<0.05) increased in treated animals than those of control being 6.08 (control), 7.56 (T1), 6.43 (T2), 6.95 (T3) and 7.35 (T4) for milk yield and 7.96 (control), 9.84 (T1), 8.5 (T2), 9.1 (T3) and 8.97 (T4) for FCM yield, respectively. Daily fat, SNF, lactose and protein yield were significantly (p<0.05) increased with treated groups than control group. Milk composition was not affected by medicinal plant s additives except that lactose content significantly (p<0.05) increased with treated animals than those of control being 4.5, 5.05, 4.84, 4.94 and 4.97 respectively. However, fat content was slightly (p>0.05) decreased with treated groups being 6.27, 6.11, 6.09, 6.19 and 5.54 for control, T1, T2, T3 and T4, respectively. The calculated efficiencies of milk yield/DMI and 4% FCM/DMI were improved (p<0.05) in treatment (T2) compared with other groups. Fenugreek seeds (FG) treatments showed non significant lower values of cholesterol and total lipids, however, FG significantly (p<0.05) increased blood glucose , TP, Albumin and creatinine compared with other groups. Values of blood plasma for globulin, urea, Alk-p-ase and GOT were not significantly affected by added of medicinal plant s.
