Abstract: This experiment was aimed to study the effects of dietary fiber sources on the meat quality,amino acid content and nutritive value of Sichuan White geese.120 Sichuan White geese at similar body weight of 28 days old were randomly divided into 4 groups,3 replicates in each group with 10 geese,used floor rearing,and separately fed with alfalfa,ryegrass,oat grass and peanut dietary.Geese had access to feed and water ad libitum in the experiment period.The feeding experiment lasted for 42 days.The results showed that shear force,meat color,drip loss rate,crude fat and amino acid content were significantly affected under same nitrogen,energy and feed intake level (P<0.05),the shear forces of the alfalfa and peanut groups were significantly lower than that of ryegrass and oat grass groups (P<0.05),the drip loss rate of alfalfa,oat grass and peanut groups were significantly lower than that of ryegrass group (P<0.05),the crude fat of oat grass group was significantly higher than that of other groups (P<0.05),while the peanut group was significantly lower than that of other groups (P<0.05).There was no significant effect of different fiber source dietary on moisture,ash and crude protein content (P>0.05).Adding alfalfa meal powder to the diet could improve the water retention of the goose meat,increase its tenderness,and also increase the umami amino acid content in the goose meat.So,it was recommended to add alfalfa powder to the meat goose diet in order to improve its meat quality and nutritive value.

Key words: dietary fiber source; Sichuan White geese; meat quality; amino acid
