摘要
探讨新型饲料风味剂L-茶氨酸对肥育猪采食行为的影响。对照组饲喂玉米-豆粕型日粮,试验1、2和3组分别于日粮中添加200、500和1 000mg/kg的L-茶氨酸,试验期36d。结果表明:与对照组相比,试验3组平均日采食量显著增加;试验2、3组采食次数显著降低,试验1组的采食次数无显著性变化。试验2、3组采食时间显著增加,试验1组采食时间无显著性变化。试验2、3组的采食速度升高,但无显著变化,试验1组采食速度显著降低。添加500和1 000mg/kg茶氨酸可增加育肥猪日采食时间和采食速率,进而提高日采食量和日增重,缩短肥育时间。
The aim was to explore the effect of L-theanine on intake behavior of finishing pigs. The control group was fed a basal diet containing 0%L-theanine and the test groups received 200, 500 and 1 000 mg/kg L-theanine for 36 days. The results showed that： the ADFI of group 3 was significantly higher than that of the control group; compared with the control group, in take times of groups 2 and 3 were significantly reduced,but there was no significant change in intake times of groups 1 ; Intake frequency of groups 2 and 3 were faster than that of the control group, but there were no significant changes, intake frequency of group 1 significantly reduced. Adding 500 and 1 000 mg/kg L-theanine can enhance intake time and intake frequency in finishing pigs,and improve the feed intake and weight gain, shorten the fattening time.
