Effects of Pyrroloquinoline Quinone Disodium on Performance, Antioxidant Status and Plasma Biochemical Parameters of Laying Hens
摘要
Abstract
The current study aimed to evaluate the biological safety of pyrroloquinoline quinone disodium (PQQ · Na2) for laying hens and investigated the effects of dietary PQQ · Na2 suplemental levels on performance,antioxidant status and plasma biochemical parameters.Five hundred and forty 25-week-old Hyline Grey laying hens were randomly divided into 5 groups with each group consisted of 6 replicates of 18 birds each.The laying hens in the 5 groups were fed 5 experimental diets with 0 (control),0.04,0.08,0.12 mg/kg PQQ · Na2 and 200 mg/kg vitamin E,respectively.All hens were fed the diets for a 1-week adaptation followed by a 24-week trial period.The result showed as follows:1) diet supplemented with 0.04 to 0.12 mg/kg PQQ · Na2 did not affect the performance of laying hens (P＞0.05).2) Compared with the control group,the Haugh unit was significantly increased by diet supplemented with 0.04 to 0.12 mg/kg PQQ · Na2 (P＜0.05),and the eggshell thickness was significantly increased by diet supplemented with 0.08 mg/kg PQQ · Na2 at the week 24 of trial (P＜0.05).3) Compared with the control group,the activities of plasma glutathion peroxidase (GSH-Px) (week 12) and total superoxide dismutase (T-SOD) (week 2 and 24) were significantly increased by diet supplemented with 0.08 and 0.12 mg/kg PQQ · Na2 (P＜0.05).4) Compared with the control group,diet supplemented with PQQ · Na2 at 0.08 mg/kg significantly decreased the content of heart carbonyl group and significantly increased the hepatic total antioxidant capacity (T-AOC) (P＜0.05),and diet supplemented with 0.12 mg/kg PQQ · Na2 significantly decreased the hepatic malondialdehyde (MDA) content (P＜0.05).Above results indicate that the supplementation of PQQ · Na2 at 0.08 to 0.12 mg/kg in laying hens' diet do not have negative effects,but can enhance the laying hens' antioxidant function.The suitable supplemental level of PQQ · Na2 in laying hens' diet is 0.08 mg/kg by comprehensive considering of the influence factors.关键词
