- Abstract
In-vitro study was conducted to evaluate the effect of dried yeast (Saccharomyces cervisiae) and yeast selenium as a biological additives, sodium acetate and sodium succinate as a chemical additives and chamomile flower, garlic and fenugreek seeds as natural additives on dry matter and organic matter disappearances. Results clearly indicated that combination of yeast and chemical mixture and combination of chamomile and chemical mixture supplementation were 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 biological, natural and chemical supplements on the productive performance of lactating buffaloes. Treatments were; 1) control (60% concentrate feed mixture "CFM", 20% rice straw and 20% berseem clover); 2) control + chemical mixture (sodium acetate 100 g/head/day + sodium succinate 3.5 g/head/day); 3) control + chemical mixture + dry yeast 10 g/head/day and 4) control + chemical mixture + chamomile flower 10 g/head/ day. Dry matter intake was significantly increased for animals fed rations of T1, T2 and T3 compared with control. Apparent nutrients digestibility were significantly (P<0.05) improved by treatments. Milk yield and 4% fat corrected milk were significantly (P<0.05) higher in animals fed additives than control. Milk protein, fat, lactose, total solids and ash contents were higher (P<0.05) in animals fed rations of T1, T2 and T3 compared with control. Feed efficiency (Milk yield/ DMI and FCM/DMI) was higher (P<0.05) for animals fed experimental additives than animals fed control. Animals fed on T1, T2 and T3 rations have a higher value of serum total protein, albumin, globulin and glucose contents than control animals. The results of the present study suggest that adding the combination of chamomile, sodium acetate and sodium succinate for lactating buffaloes was improved nutrients digestibility, milk production and composition and feed efficiency with no deleterious effect on general health of the treated animals.
