This experiment was conducted to explore the effects of silage corn stalk mixed diet supplemented with different proportions of sodium bicarbonate on growth performance, serum biochemical indexes, slaughter traits and viscera indexes of Zi geese. A total of 120 four-week-old Zi geese were randomly divided into 4 groups with 3 replicates in each group and 10 geese per replicate. Geese in groups A, B, C and D were fed silage corn stalk mixed diets, in which sodium bicarbonate was supplemented at proportions of 0, 1%, 2% and 3%, respectively. The experiment lasted for 40 days. The results showed as follows:1) among 4 groups, there were no significant differences in the growth performance, slaughter traits and viscera indexes (P>0.05). 2) Serum total protein (TP) content of groups B and C were significantly higher than those of groups A and D (P<0.05). Serum creatine kinase (CK) activity of group D was significantly higher than that of group B (P<0.05). Serum lactic dehydrogenase (LDH) activity of groups C and D were significantly higher than that of group B (P<0.05). It is concluded that, under these experimental conditions, based on the evaluation of growth performance, serum biochemical indexes, slaughter traits and viscera indexes of Zi geese, there is no need to add sodium bicarbonate when adding appropriate amount (dry matter content in the diet is less than 15.09%) of silage corn stalk in the diet of Zi geese during growing period.
