In-vitro study was conducted to evaluate the effect of dried yeast (Saccharomyces cervisiae1026) and yeast selenium as biological additives, sodium acetate and sodium succinate as chemical additives and chamomile flower, garlic and fenugreek seeds as natural additives on dry matter (IVDMD) and organic matter (IVOMD) disappearances. Results clearly indicated that combination of yeast and chemical mixture and combination of chamomile and chemical mixture supplementation recorded the highest rate of IVDMD and IVOMD. Sixteen lactating buffaloes after two weeks of calving were divided into 4 groups (four animals each) using complete random block design to evaluate the effect of chemical mixture (as second control), yeast and chemical mixture and chamomile and chemical mixture on the productivity of lactating buffaloes. Animals were fed on 60% concentrate feed mixture (CFM), 20% rice straw and 20% berseem clover (control group), control ration + chemical mixture (sodium acetate 100 g/head/day + sodium succinate 3.5 g/head/day)(T1); control ration + chemical mixture + dry yeast 10 g/head/day (T2) and control ration + chemical mixture + chamomile flower 10 g/head/day (T3). Dry matter intake (DMI) was slightly increased for animals fed on T1, T2 and T3 rations compared with control. Apparent nutrients digestibility and total digestible nutrients (TDN) were significantly improved by treatments. Milk yield, 4% fat corrected milk (FCM), milk protein, fat, lactose, total solids, ash contents, feed efficiency (Milk yield/DMI and FCM/DMI) and economic efficiency were significantly higher for animals fed T3 followed by T1 and T2 and then control. Serum total protein, albumin, globulin and glucose contents were higher in animals received experimental additives than those received control. It may be concluded that adding the combination of chamomile, sodium acetate and sodium succinate to rations improved the productivity of lactating buffaloes with no deleterious effects on general health.
