摘要

This experiment was undertaken to evaluate the effects of different levels of soluble and insoluble fibers on growth performance and blood indices in ostrich at the age of 1 to 6 months. Thirty 30-day-old ostriches (males and females) were randomly assigned to five treatments with six replicates. There were five dietary treatments consisted of (1) basal diet; (2 and 3) diets containing 2 and 4% more soluble fibers (SF) than basal diet, and (4 and 5) diets containing 2 and 4% more insoluble fibers (ISF) than the basal diet. The dietary treatments had no significant influence on growth performance of ostriches. By increasing the levels of SF and ISF, the concentration of blood glucose (P < 0.0001) and high-density lipoprotein (HDL,P = 0.0046) increased, while the plasma concentration of triglyceride (P < 0.0001) and very-low-density lipoprotein (VLDL,P = 0.0006) decreased. The plasma enzyme activity of alanine aminotransferase (ALT) decreased in ostriches fed diet containing 4% more SF as compared with control (P < 0.0006). Body weight gain (BWG) at the starter phase (3-4 months) was higher than the pre-starter (1-2 months) and grower (5-6 months) phases (P < 0.0001). The highest concentration of blood glucose was observed at 2 months of age while the lowest magnitude was found at 4 months of age (P < 0.0001). The plasma cholesterol concentration increased at 4 months and decreased at 6 months as compared with 2 months (P < 0.0001). The concentration of HDL and LDL at 4 months of age was higher than two other ages (P < 0.0001). The blood concentration of triglyceride (P < 0.0001), VLDL (P < 0.0001), and ALT (P = 0.0005) decreased as ostriches grew up. It could be concluded that increasing the levels of soluble and insoluble fibers in the diet up to 4% more than previous recommendation may not have negative effects on growth performances and blood indices in ostrich.
