本试验旨在研究日粮中添加不同水平γ-氨基丁酸（GABA）对哺乳母猪生产性能、激素水平的影响及其量效关系。选取经产大白母猪40头,采用单因子试验设计,按GABA添加水平（0、25、50、100、150 mg/kg）设对照组和试验组共5个处理,每个处理8个重复,每个重复1头猪,试验期21 d。结果表明,GABA在促进母猪摄食方面效果明显,对减少体重损失、缩短断奶-发情间隔及促进仔猪生长也有一定效果。其作用程度与日粮添加剂量和哺乳阶段均密切相关,低添加水平范围作用更为明显,且随着试验时间的延长,作用呈增强趋势。就促采食作用而言,50 mg/kg GABA的效果要优于其他水平,该组母猪不仅在分娩后第1周（P

This study was conducted to investigate the effects of different levels of γ-amino butyric acid （GABA） from 0 to 150 mg/kg on the performance and serum hormone levels in Yorkshire lactating sows. Forty sows were randomly allocated to five treatments with eight replicates in each and one sow in each replicate according to single factor design. The trial lasted for 21 days. The results showed that 1） the GABA had a positive effect on improving feed intake, weight loss, estrus interval and performance of piglets to some extent. The effect of G...
