Abstract
IThe results show that no significant differences were observed in the effects of the treatments on glucose, calcium, phosphorus, and lactate dehydrogenase. Orthogonal contrast between wheat bran and soybean hull had significant differences in cholesterol, HDL, and LDL. Experimental treatments had no significant effect on cholesterol, triglyceride, HDL, and LDL concentrations. T3 was significantly different for orthogonal contrast between yeast and soybean hull for T3 and T4 wheat bran and soybean hull had a significant difference, but the experimental treatments had no significant effect on thyroid hormones. The treatment containing non-starch carbohydrates had no significant effect on immune responses of broilers antibody after SRBC injection. Orthogonal contrast between yeast and wheat bran, wheat bran, and soybean hull had significant differences in tibia length and wheat bran and soybean hull had a significant difference in the calcium of the tibia. Other characteristics of the tibia such as diameter, weight, and phosphorus were not affected. The effect of experimental treatments indicated that different sources of non-starch carbohydrates had a significant effect on tibia length. Treatments containing 5 and 10 percent wheat bran had the shortest length compared to the treatments of 0.2 percent yeast and 6 percent soybean hulls. The calcium and phosphorus content of the tibia was not affected by treatments. The experimental treatments had no significant effect on the population of E-Coli and Lactobacillus bacteria in the ileum.
