Preparation of Extruded and Expanded Cyperus esculentus Pellet Feed and Its Effects on Growth Performance,Immune and Antioxidant Functions and Economic Benefits in Broilers
摘要
Abstract
The experiment aimed to study the extrusion puffing preparation process of extruded and puffed Cyperus esculentus pellet feed,and to investigate its effects on growth performance,serum immune function,serum antioxidant activity,and economic benefits of broilers.Single-factor and response surface experi-ments were used to optimize the extrusion and puffing preparation process parameters.A total of 400 21-day-old white-feathered broilers were randomly divided into 4 groups,with 10 replicates per group and 10 broilers per replicate.The experimental diets supplemented with 0(control group A),5%(group B),10%(group C)and 15%(group D)extruded and puffed Cyperus esculentus pellet feed.The trial lasted 21 d.The results showed that:①the optimal preparation parameters for extruded and puffed Cyperus esculentus pellet feed were as follows:material moisture content of 21%,screw speed of 320 r/min,and Zone Ⅲ temperature of 170℃,under which the gelatinization degree was 91.1%.② Compared with the control group,the ADG and ADFI of broil-ers in groups B,C,and D were significantly increased(P<0.05),while F/G was significantly decreased(P<0.05).③ Compared with the control group,the IgA,IgG,and IgM levels in broilers of groups B,C,and D were significantly increased(P<0.05),while IL-2 and IL-6 levels were decreased,with a significant reduc-tion in IL-2 levels(P<0.05).④ Compared with the control group,the activities of T-AOC,SOD,GSH-Px,and CAT in broilers of groups B,C,and D were significantly increased(P<0.05),while MDA content was sig-nificantly decreased(P<0.05).⑤ Compared with the control group,the profit margins of broiler farming in groups B,C,and D increased by 21.32%,21.32%,and 25.38%,respectively.In conclusion,extruded and puffed Cyperus esculentus pellet feed could improve the growth performance,serum immune function,serum antioxidant capacity,and economic benefits of broilers.关键词
