Analysis of Some Serum Biochemical Indexes of Angora Rabbits in Different Seasons
The production of Angora rabbits is affected by seasonal change,especially summer heat stress,and serum biochemical indexes are potential indicators to reflect this change.This study analyzed the changes of serum biochemical indexes of Angora rabbits in different seasons(spring,summer,and autumn)and sex(male and female),aiming to ascertain the influence of seasons on the biochemical indexes of Angora rabbits,and to screen the relevant indexes of heat stress to guide the summer production of Angora rabbits.The results showed that the serum ALP levels of male and female rabbits decreased in summer and increased in autumn,respectively.The CK level of male rabbits increased significantly in early August,decreased significantly in mid-August,and rose again in autumn.LDH level increased significantly in both male and female rabbits in early August,and continued to increase significantly in mid-August in male rabbits and returned to normal in autumn,while that returned to normal in mid-August in female rabbits.The TP level of male rabbits had no change in early August,but significantly increased in mid-August and autumn(P<0.05),while that of female rabbits had no significant change(P>0.05).ALB decreased slightly in early August and then increased significantly(P<0.05).The UREA level of male rabbits did not change significantly in seasons(P>0.05),but the UREA level of female rabbits in autumn was lower than that in other seasons.There was no seasonal difference in ALT and AST in male rabbits(P>0.05),and the levels of ALT and AST in female rabbits were the lowest in mid-August(P<0.05).AST/ALT of male rabbits increased gradually with heat stress,which was significantly higher in mid-August than in spring,and recovered in autumn.The AST/ALT of female rabbits increased significantly in early August,and then basically recovered.In summary,the main change indexes were ALP,ALB,LDH,and AST/ALT for heat stress of Angora rabbit.Male rabbits suffer from persistent heat stress,while female rabbits were sensitive but recovered quickly.
