Abstract：The experiment aimed to investigate the effects of adding selenium-enriched earthworm powder to the diet on the growth performance,serum biochemical indexes,antioxidant function,selenium deposition in muscle tissue,and meat quality of Belgian rabbits.A total of 192 Belgian rabbits,aged seven weeks and with similar body conditions,were randomly divided into four groups,with four replicates per group and 12 Belgian rabbits per replicate(half male and half female).The control group(K group)was fed a basic diet,while groups A,B,and C were fed the basic diet supplemented with 0.5％,1.0％,and 2.0％selenium-enriched earthworm powder,respectively.The pre-test period was seven days and the formal test period was 28 days.The results showed that the levels of selenomethionine,methylselenocysteine,and total selenium in the muscle tissue in group C were extremely higher than those in other groups(P＜0.01).The levels of alanine aminotransferase(ALT)in serum and the activity of glutathione peroxidase(GSH-Px)in groups A,B,and C were extremely higher than those in the control group(P＜0.01).The activity of aspartate aminotransferase(AST)and total antioxidant capacity(T-AOC)of serum in group B were extremely higher than those in other groups(P＜0.01).The level of low-density lipoprotein cholesterol(LDL-C)in the serum in group A was extremely higher than that in the control group and group B(P＜0.01).The activity of alkaline phosphatase(ALP)in the serum in groups B and C was extremely higher than that in other groups(P＜0.01),and the content of malondialdehyde(MDA)was extremely lower than that in other groups(P＜0.01).The lightness value(L*value)of the muscle in group C was extremely higher than that in other groups(P＜0.0l);the redness value(a*value)of the muscle in group B was extremely higher than that in other groups(P＜0.01).The study indicates that adding 2.0％selenium-enriched earthworm powder to the diet can improve the antioxidant function and selenium transformation ability in the muscles of Belgian rabbits.
