چکیده مقاله :
The present study was conducted to evaluate the effects of corn replacement with triticale and wheat screen-ing and supplemented with Xylanase enzymes in 144 W-36 Hay lines. Treatments were arranged from 15 to 25 weeks of age. With 6 treatments 4 replicates and 6 pullets in each. Results of the experiment have shown the highest body weight gain by treatment 5 (wheat screening without enzymes) (P=0.99), Significant de-creased were observed in feed intake by treatments 5 during 6 weeks of growth period. In terms of egg quality, the results have showed the significant effect on yolk color by replacing treatments (P<0.05). In other hand result have indicated that there were no significant differences in body mass index between treatments. At the end of the study, blood samples were collected in the test tubes to determine cholesterol. A higher concentration of low density lipoprotein (LDL) was observed by experimental treatments in com-parison to control. As well as treatments 3 and 4 were shown the highest concentration of low density se-rum lipoprotein (LDL) (P<0.05). No significant differences were found in serum triglyceride concentration by experimental and control treatments. At the end of the experiment, no significant differences were indi-cated in egg cholesterol and intestinal viscosity (P>0.05). The results of this study have shown no adverse effect on performance and health status by up to 30% wheat screening and triticale in pullet diet.
