IMPLEMENTATION ON DIET OF PROBIOTIC Saccharomyces spp.Gb-7 AND Gb-9 ISOLATED FROM COLON OF NATIVE CHICKENS ON PERFORMANCE AND CHOLESTEROL SERUM OF BROILER

The current research was conducted in order to evaluate the effect of two isolates of probiotics (Saccharomyces spp. Gb-7 and Gb-9) isolation from colon of native chickens on total serum cholesterol and performance in broilers. A total 240 broilers were randomly diveded into 4 groups (A,B,C, and D) of 10 birdss each. The diets for group A, B, and C were suplemented with probiotics 0.30% Saccharomyces spp.Gb-7, 0.30% Saccharomyces spp.Gb-9, and 0.15% Saccharomyces spp.Gb-7+0.15% Saccharomyces spp.Gb-9 of feed, resvectively. Group D diet had no probiotic (control). The blood samples were allowed to clot in a sample bottle and serum harvested was used to determine the total serum cholesterol content with the aid of commercial kit. The result showed that the probiotic fed groups had a significant (P<0,05) reduction in serum cholesterol levels than the control (group D). The bird consumed probiotic Saccharomyces spp. had higher live weight gain (LWG)s and were efficient in using feed compared to those unsupplemented probiotics in their diets (P<0.05). It was concluded that using of probiotics (Saccharomyces spp.Gb-7; Gb-9; and it’s combinations) isolation from colon of native chickens could increase growth performance and feed efficiency of broiler up to six weeks of age. Moreover it decreased the serum cholesterol contents of birds. Key words: Saccharomyces spp., probiotics, performance, cholesterol
