Safety Evaluation of Sodium Sulfate in Laying Hens Diet
摘要
Abstract
This experiment was conducted to evaluate the safety of high doses of sodium sulfate supplementa-tion in laying hens diet by determining performance, egg quality, hymnological indices and histopathological changes. Four hundred and fifty 20-week-old Hy-Line white laying hens with similar body weight and laying rate were randomly allocated to 5 groups with 6 replicates per group and 15 birds per replicate. Birds were fed basal diets supplemented with 0 ( control) , 0.3% ( the recommended available dose, RAD) , 0.6% ( two fold of RAD) , 1.5% ( five fold of RAD) and 3.0% ( ten fold of RAD) sodium sulfate for 10 weeks, respectively. The results showed as follows:1) dietary sodium sulfate supplemental levels had no significant effects on daily egg mass, average egg mass, average daily feed intake, laying rate, the ratio of feed to egg (P>0.05). 2) Compared with the control group, 0.3% and 0.6% groups had a trend of improving egg quality (P>0.05);and compared with 0.6% group, the egg quality of high dose groups (1.5% and 3.0%) was significantly de-creased (P<0.05). 3) Dietary sodium sulfate supplemental levels had no significant effects on blood routine parameters ( P>0.05) . 4) Compared with the control group, 0.3% and 0.6% groups had no significant effects on the contents of glucose, uric acid, creatinine, total protein, albumin, usea nitrogen, total bilirubin and the activities of glutamic-pyruvic transaminase, glutamic-oxalacetic transaminase, alkaline phosphatase in plasma (P>0.05);compared with 0.6% group, high dose groups (1.5% and 3%) significantly increased plasma glu-tamic-pyruvic transaminase activity ( P<0.01) . 5) Dietary sodium sulfate added levels in excess of 1.5% could damaged major organ tissues. It is indicated that dietary sodium sulfate supplemental level at 0 to 0.6% is safe in laying hens diet.关键词
