饲粮添加γ-氨基丁酸对海兰褐蛋鸡蛋中γ-氨基丁酸含量、蛋品质及产蛋性能的影响
Effects of dietary supplementations with γ-aminobutyric acid on γ-aminobutyric acid content of egg,egg quality,and laying production in Hailan brown laying hens
摘要
Abstract
The experiment aimed to investigate the effect of different levels of γ-aminobutyric acid(GABA)on GABA content,egg quality,and laying production in Hailan brown laying hens.A tatol of 180 healthy Hailan brown laying hens were divided into five groups with three replicates each with 12 hens in each replicate.The control group was fed a basic diet,while the experimental groups were fed the basic diet supplemented with 50,100,200,and 400 mg/kg GABA,respectively.The pre-test lasted for seven days and the formal test lasted for 30 days.The results showed that throughout the entire test period,the GABA content in the yolks of all experimental groups was higher than that of the control group,and the 400 mg/kg GABA group was significantly higher than the other groups(P<0.05).The GABA content in the albumen of all experimental groups was significantly higher than that of the control group(P<0.05),and the 400 mg/kg GABA group was significantly higher than the other groups(P<0.05).The eggshell strength of 100 mg/kg GABA group was significantly higher than that of control group(P<0.05).Test for 10 and 20 days,Haugh unit in 400 mg/kg GABA group was significantly higher than that in control group(P<0.05).Test for 30 days,100 mg/kg GABA albumen height and Haugh unit were significantly higher than those in control group(P<0.05).On the 20th and 30th days,the feed to egg ratio of 200 and 400 mg/kg GABA groups was significantly lower than that of control group(P<0.05).The study indicates that adding GABA in the diet can increase the content of GABA in egg yolk and albumen,and improve egg quality and egg production of Hailan brown laying hens.It is recommended to add GABA at a dosage of 400 mg/kg for a period of 30 days.关键词
