Arginine Affects Appetite via Nitric Oxide in Ducks
The objective of the study was to investigate the mechanism by which arginineregulates feed intake in Pekin ducks.In experiment 1,one hundred and forty four 1-d-old malePekin ducks were randomly allotted to 3 dietary treatments with 6 replicate pens of 8 birds per pen.Birds in each group were fed corn-corn gluten meals diet containing 0.65,0.95 and 1.45%arginine,respectively.Ducks fed the diet containing 0.65%arginine had lower feed intake andplasma nitric oxide level (P < 0.05) than the other two groups.In experiment 2,twenty 11-dayducks were allotted to one of two treatments.After 2-hours fasting,birds in the two groups were intraperitoneally administrated saline and NG-nitro-L-arginine methyl ester (L-NAME) for 3 days,respectively.Feed intake (P < 0.07) and plasma nitric oxide concentration (P < 0.05) 2 hourspost-injection in L-NAME administrated group were lower than those of control group.Inconclusion,the study implied that argininemodifies feeding behavior possibly through controlling endogenous synthesis of nitric oxide in Pekin ducks.
