Effects of Mycotoxin Adsorbents on Performance, Yolk Trace Element Contents and Serum Antioxidant and Biochemical Indices of Laying Hens
摘要
Abstract
This experiment was conducted to study the effects of mycotoxin adsorbents ( named CZ and SF) on performance, yolk trace element contents and serum antioxidant and biochemical indices of laying hens. A total of 216 healthy 38-week-old laying hens were randomly divided into 3 groups with 6 replicates per group and 12 hens per replicate. Hens in the control group were fed a basal diet, and hens in experimental groups ( group CZ and group SF) were fed the basal diets supplemented with 0.5 g/kg CZ and SF, respectively. The adjustment period lasted for 10 days, and the experimental period lasted for 35 days. The results showed as follows: 1 ) compared with the control group, the laying rate and daily egg production of group CZ were significantly in-creased during 3 to 5 weeks of experiment ( P<0.05) . Dietary mycotoxin adsorbents had no effect on the aver-age egg weight, average daily feed intake, feed to egg ratio and mortality and cull rate ( P>0.05) . 2) Com-pared with the control group, while the contents of copper and manganese in yolk of experimental groups at the 14th and 35th day had no significant difference ( P>0.05) , the content of zinc in yolk of group CZ at the 14th day was significantly increased ( P<0.05) . 3) Dietary mycotoxin adsorbents had no effect on serum glutathione peroxidase activity and malonaldehyde content of laying hens at the 14th and 35th day (P>0.05). Compared with the control group, and the serum total antioxidant capacity of experimental groups at the 14th day was sig-nificantly increased ( P<0.05) , and the serum total superoxide dismutase activity of group SF at the 35th day was significantly increased (P<0.05). 4) Compared with the control group, the serum alkaline phosphatase activity and glucose content of laying hens of group CZ were significantly decreased ( P<0.05) , the serum to-tal cholesterol content of group SF was significantly decreased ( P<0.05) . In conclusion, dietary supplemented with the mycotoxin adsorbent CZ improves the egg production of laying hens; both CZ and SF adsorbents en-hance serum antioxidant capability and improve serum biochemical indices.关键词
