| 摘 要： | 本试验研究了肉鸡腹水症(PHS)对组织钙磷分布及饲料钙磷利用率的影响。120只1日龄艾维茵(AA)肉鸡随机分成2组,即对照组和试验组,每组6个重复,每个重复10只鸡。试验组采用低温(LAT)和饲粮添加三碘甲腺原氨酸(T3,1.5mg/kg)诱导产生腹水症。试验期为21d。试验结果表明:1)14日龄时,试验组肉鸡的心脏、肝脏、十二指肠中钙含量与对照组相比,有增加趋势,胫骨、血清钙有下降趋势,但差异均不显著(P>0.05)。试验组肉鸡的心脏磷含量极显著低于对照组(P<0.01),十二指肠磷含量显著高于对照组(P<0.05)。饲料中钙磷利用率,试验组极显著低于对照组(P<0.01)。2)21日龄时,试验组肉鸡的心脏、肝脏中的钙含量显著高于对照组(P<0.05)。十二指肠、胫骨、血清中的钙含量两组间无显著差异(P>0.05)。十二指肠、血清磷含量试验组显著高于对照组(P<0.05),其余组织磷含量两组间无显著差异(P>0.05)。饲料中钙磷利用率,试验组极显著低于对照组(P<0.01)。3)血清碱性磷酸酶含量14、21日龄试验组和对照组差异均不显著(P>0.05)。

| Abstract: | The experiment was conducted to investigate the effects of pulmonary hypertension syndrome (PHS)ofbroilers on calcium and phosphorus contents of organ and the availability of calcium and phosphorus.one hundred andtwenty 1- day- old Arbor Acres chickens were randomly divided into 2 groups (control group and test group),six replicatesper group and 10 broilers per replicate.In test group,PHS was induced with 3,3',5- triiodothyronine (T3,1.5 mg/kg)andlow ambient temperature (LAT).The results showed that:1)The calcium contents of heart,liver,duodenum at 14 days oldwere higher,and tibia,serum were lower but not significant (P > 0.05),the phosphorus content of heart was lower (P <0.01)and duodenum was higher(P < 0.05),the availability of calcium and phosphorus were lower(P < 0.01)in test groupthan those in control group.2)The calcium contents of heart and liver at 21 days old were higher (P < 0.05),and duode-num,tibia and serum were not significant (P > 0.05),the phosphorus contents of duodenum and serum were higher (P <0.05),and the else were not significant (P > 0.05),the availability of calcium and phosphorus were lower (P < 0.01)intest group than those in control group.3)The alkaline phosphatase of serum was not significant (P > 0.05)between testgroup and control group during the whole trial. |
