Effects of Hermetia illucens Larvae Meal on Growth Performance,Antioxidant Capacity,Antibody Level and Serum Biochemical Indexes of Sichuan White Geese
This study was conducted to investigate the effects of replacing feed protein by Hermetia illu-cens larvae meal(HILM)on growth performance,antioxidant capacity,antibody level and serum bio-chemical indexes of Sichuan white geese.A total of 64 healthy 1-day-old Sichuan white geese were random-ly allocated into 4 groups with 4 replicates in each group and 4 geese in each replicate,namely Control,2％HILM,4％HILM and 8％HILM groups,and were fed with diets containing 0,2％,4％and 8％of HILM,respectively.The geese can access to food and water ad libitum in the 40 d of experiment period.The results showed that compared with the control group,the replacement of feed protein with HILM could increase the Average Daily Gain(ADG)of geese,with a significant difference in 2％HILM group(p＜0.05).The serum Total Antioxidant Capacity(T-AOC)and Glutathione Peroxidase(GSH-Px)in each HILM replacement group showed an increasing trend,and the serum GSH-Px in the 8％HILM group increased significantly(p＜0.05).7 d after the 2nd immunization,the serum H5-R13 and H7-R4 an-tibody titer were increased in each HILM replacement group.The serum H5-R13 antibody titer in the 2％HILM group and the serum H7-R4 antibody titer in the 4％HILM group were both significantly increased(p＜0.05).There was no significant effect on serum biochemical indexes and organ indexes in each HILM replacement group(p＞0.05).In conclusion,HILM can improve the growth performance,antioxidant capacity and enhance the immunity effect of avian influenza vaccine of Sichuan white geese,and the suitable replacement level is 2％.
