摘要
Abstract
This study aimed to assess the impact of graded levels of Phellinus linteus extract(PLE)in the diet on the health and productive performance of late-phase laying hens.Four hundred and eighty 65-week-old Hy-Line Brown laying hens were randomly assigned to 4 groups(6 replicates×20 hens each).The control group(CON)received a basal diet.The experimental diets for groups T1,T2,and T3 were formulated by supplementing the basal diet with 100,200,and 400 mg/kg PLE(polysaccharide-based),respectively.The trial included a 1-week adaptation period followed by an 8-week formal trial.The results showed that:1)Production Performance:The T2 group showed a significant increase in laying rate by 3.20%and a significant decrease in the feed-to-egg ratio by 4.76%(P＜0.05).Moreover,the average egg weight was significantly increased by 1.67%and 2.60%in the T2 and T3 groups,respectively(P＜0.05).2)Egg Quality:The yolk color and Haugh unit of T2 group were significantly improved(P＜0.05),with values superior to CON and T1 groups;eggshell strength and thickness of all experimental groups showed an increasing trend without significant difference(P＞0.05).3)Serum Biochemical Indices:In all experimental groups,serum T-AOC and SOD activity rose significantly,whereas MDA content declined significantly(P＜0.05),with the T2 group presenting the most optimal profile.Specifically,the T2 group demonstrated a significant decline in serum TC and TG concentrations and a significant increase in HDL-C(P＜0.05).An optimal supplementation level of 200 mg/kg PLE was identified,as it elicited significant improvements in key areas including production performance,egg quality,antioxidant status,and the serum lipid profile of laying hens during the late-phase production cycle.关键词
