| In order to collect physiological,biochemical and anatomical background data of HJD-SPF ducks in different sex and age stages,the effects of age and sex on the data measured in HJD-SPF ducks were observed,the routine methods of blood physiological and biochemical detection and anatomy experiment were used in this paper.Physiological indexes（18 items）,blood biochemical indexes（21 items）and anatomical data（23 items）of five weeks old HJD-SPF ducks were measured.Meanwhile,SPSS20.0 software was used to analyze the variance of the measured data between the same sex groups.The same data of the same week were tested by t-test.The results showed that:1 In physiological indexes,there were significant differences（P<0.05）or very significant differences（P<0.01）in body temperature,breath frequency,RBC,WBC,HGB,EO,RDW,HR,HCT,MCV,NE,MCH,SBP,MCHC and DBP between the male and female at one or more weeks of age,but there were no significant differences in the LY,BA,MO between the male and female ducks at all weeks of age（P>0.05）.2 In biochemical indices,there were significant differences（P<0.05）or very significant differences（P<0.01）in ALT,LDL,AST,ALB,LDH,GGT,UA,TB,DB,HDL,TP,BUN,GLO,CRE,GLU,TG,TCH,K+and Ca2+between the male and female at one or more weeks of age,but there were no significant differences in the ALP and Na+between the male and female ducks at all weeks of age（P>0.05）.3 In biochemical indices,there were significant differences（P<0.05）or very significant differences（P<0.01）in weight of body,coefficient of brain,coefficient of heart,coefficient of hepar,coefficient of spleen,coefficient of left lung,coefficient of right lung,bursa of Fabricius of coefficient,coefficient of left kidney,coefficient of right kidney,coefficient of left adrenal,coefficient of right adrenal,body length,shank length,pelvic width,chest depth,chest width,keel length,duodenum,jejunum and ileum,left cecum and right cecum between the male and female at one or more weeks of age,only rectum had no significant difference between sexes at all weeks of age（P>0.05）.4 In the same data,same sex analysis,except for male BA,body temperature and femle LY,there was no significant difference between the groups（P>0.05）,all the other data groups were significant differences（P<0.05）or very significant differences（P<0.01）.It shows that the biological characteristics of experimental animals are not fixed and are constantly changing with age.Most of the data collected are affected by age and gender,and are constantly changing with age. |
