摘要：Twenty growing lambs, which were apparently healthy, of nearly the same body weight (approx. 21.45 kg) were used in this study to investigate the effect of pediococcus spp. supplementation on growth performance, nutrient digestibility and some blood serum parameters of growing lambs. Lambs were allotted into two equal groups, first group fed on the basal diet without any supplement while 2nd group fed on the basal diet and pediococcus supplementation in drinking water for continuous 10 weeks. It was noticed that Pediococcus supplementation improved final body weight, total body gain and feed conversion ratio (total dry matter, TDN and CP intake) throughout the whole experimental period by about 15.5%, 49.9%, 30.1%, 31.4% and 29.1% respectively when compared with the control> Moreover, probiotic supplementation improved nutrient digestibility and feed values of the used ration. It was observed that bacterial probiotic supplementation non significantly increased blood serum total protein and globulin concentrations, while had no clear effect of blood serum calcium, phosphorus, kidney and liver function units concentrations when compared with untreated one. Also, Pediococuus supplementation non significantly decreased blood serum lipids concentration. Moreover, it was observed that probiotic supplementation increased benefit/cost ratio% and net incoe/total cost % from 110% and 10.0% of the control to 123.12% and 23.12% of the treated group respectively. Finally bacterial probiotic supplementation in the drinking water for growing lambs improve economical efficiency of production. Generally, bacterial probiotic supplementation improve lamb growth and maximize economical efficiency of production.
