不同阶段矮小型褐壳蛋鸡血液生理生化指标测定

试验测定20、40、60周龄矮小型褐壳蛋鸡血液生理指标、血清生化指标,每一周龄公、母鸡各9只,样本量为54只。将数据进行t检验及多重比较分析,结果表明,在此3个时间点上,指标RBC、HGB、MPV、PDW、LYMF%、TP和CHO呈现上升趋势,指标HCT、MCV、RDW%、WBC、LYMF值是先下降后上升,而MCH、MCHC、PCT、PLT、MID、MID%、GRAN、GRAN%、AST、ALB、TG、GLU和ALT值是先上升后下降。同时,不同周龄鸡之间在血液生理生化指标上表现出不同项目差异显著(P0.05)。20、40及60周龄矮小型褐壳蛋鸡雌、雄间均存在显著差异(P0.05)的血液生理生化指标有RBC、HCT、HGB、WBC、LYMF和AST,这表明矮小型褐壳蛋鸡的生理和生化指标随周龄不同,在雌、雄之间的差异随之发生变化。

Determination of Values of Physiological and Biochemical Parameters in Dwarf Brown Layer

To determine the values of physiological and biochemical parameters in Dwarf brown layer at age of 20, 40 and 60 weeks and compare the variations of these data between both genders. The blood samples were collected and tested for physiological values using hematology analyzer and biochemical values using Olympus AU400 auto-analyzer. The value of RBC, HGB, MPV, PDW, LYMF%,CHO and TP were on the rise, and the value of HCT, MCV, RDW%, WBC, LYMF decreased at first and then increased. The value of MCH, MCHC, PCT,PLT， MID, MID%, GRAN, GRAN%,AST，GLU，ALB，TG and ALT increased at first and then decreased. There was a very significant difference (P<0.05) between RBC, HCT, HGB, WBC, LYMF and AST values in male and female Dwarf brown layer at age of 20,40 and 60 weeks. This showed that the values of the physiological and biochemical parameters were different between male and female Dwarf brown layer at age of 20,40 and 60 weeks.
