Abstract

This experiment was conducted to study the effects of nano-selenium on performance, egg selenium content and serum antioxidant indices of pigeons. A total of 180 pairs of healthy pigeons(180 to 210 days of age) were randomly allotted to 6 groups with 6 replicates in each group, and each replicate contained 5 pairs of pigeons. Pigeons in the control group were fed a basal diet, and pigeons in experimental groups were fed the diets supplemented with 0.1, 0.2, 0.3, 0.4 and 0.5 mg/kg nano-selenium, respectively. The adjustment period lasted for 7 days, and the experimental period lasted for 42 days. The results showed as follows:1) dietary supplemented with nano-selenium had no significant effect on the average egg weight, egg number and feed to egg ratio of pigeons in the 21st and 42nd days(P>0.05). 2) Dietary supplemented with nano-selenium had no significant effect on eggshell thickness and egg shape index of pigeons in the 21st and 42nd days(P>0.05). Compared with the control group, the yolk index of 0.2 mg/kg nano-selenium group in the 21st days was significantly increased(P<0.05), and the yolk color of 0.4 and 0.5 mg/kg nano-selenium groups in the 21st days was significantly increased(P<0.01); the yolk color of 0.5 mg/kg nano-selenium group in the 42nd days was significantly increased(P<0.01). 3) Compared with the control group, the content of manganese, zinc and copper in yolk of experimental groups in the 21st and 42nd days was no significant difference(P>0.05), the yolk selenium content of 0.4 and 0.5 mg/kg nano-selenium groups in the 21st days was significantly increased(P<0.01), and that in the 42th days was significantly increased(P<0.05). 4) Compared with the control group, the serum glutathione peroxidase(GSH-Px) activity of 0.4 and 0.5 mg/kg nano-selenium groups in the 21st days was significantly increased(P<0.01), and the serum malonaldehyde(MDA) content was significantly decreased(P<0.01), but the serum total antioxidant capacity(T-AOC) and total superoxide dismutase(T-SOD) activity had no significant difference(P>0.05); the serum T-AOC and T-SOD activity of 0.4 and 0.5 mg/kg nano-selenium groups in the 42nd days were significantly increased(P<0.05), the serum GSH-Px activity was significantly increased(P<0.01), and the serum MDA content was significantly decreased(P<0.01). In conclusion, the optimum level of nano-selenium is 0.4 mg/kg, and the experiment last for 42 days' effect is more obvious.
