SYNBIOTIC DIET SUPPLEMENTATION EFFECTS ON SEMEN CHARACTERISTICS OF WHITE LEGHORN MALES

Abstract

The present experiment was carried out at poultry farm-Agriculture College –University of Baghdad for the period of 27th/May 2005 to 27th/2/2006 aimed to study the effect of diet supplementation with synbiotic on semen characteristics of males White Leghorn (WL). A locally prepared synbiotic which used in this study prepared by mixing an equal amount from probiotic (Iraqi probiotic) contain Lactobacilli, Lactobacillus acidophilus and Bacillus subtilis bacteria and Saccharomyces cerevisiae and prebiotic were consist a non starch oligosaccharide of S. cerevisiae yeast after crashing of cell wall. Add symbiotic to diet of total 22 WL cocks, 16 weeks of age, were randomly assignal into two treatment groups. Cocks in T1 were fed a standard diet and used as control group, while cocks in T2 were fed diet supplemented with synbiotic at the rat of 5 kg/ton feed. The data showed that dietary treatment were significantly (p<0.01) increased semen volume per ejaculated volume and the percentages of individual and mass motility movement of the sperms in the semen. The dietary treatment were significantly (p<0.01) decreased the percentages of dead and abnormal sperms in the semen. Key words: synbiotic, semen characteristics, volume per ejaculated, individual and mass motility movement, deat and abnormal, sperms, males White Leghorn.
