摘要
本试验旨在研究海兰灰蛋鸡患输卵管囊肿对屠宰性能、器官指数、血清生化指标及组织病理学的影响。选取同一饲养环境下的54周龄海兰灰蛋鸡16只,分为对照组(CTR,n=9)和输卵管囊肿组(CFT,n=7)进行屠宰并采集血清样品,测定蛋鸡屠宰性能、器官指数和血清生化等指标。结果表明:1)输卵管囊肿组蛋鸡的活重和屠体重较对照组极显著升高(P<0.01),屠体率显著升高(P<0.05),但全净膛率极显著降低(P<0.01)。2)输卵管囊肿组蛋鸡盲肠指数、十二指肠重、空肠重和回肠重及对应的器官指数较对照组极显著降低(P<0.01),盲肠重、卵巢指数显著低于对照组(P<0.05)。3)输卵管囊肿组蛋鸡血清中丙氨酸氨基转移酶(ALT)和天门冬氨酸氨基转移酶(AST)活性较对照组极显著升高(P<0.01),血清碱性磷酸酶(ALP)活性低于对照组(P<0.01)。4)输卵管囊肿使蛋鸡肺、卵巢及输卵管出现不同程度的病理性损伤,如肺广泛性出血,肺泡腔内充满大量红色渗出物;卵巢皮质区毛细血管充血,炎性细胞浸润;输卵管膨大部出现绒毛断裂,浆膜层有炎性细胞浸润等。综上所述,输卵管囊肿显著影响了蛋鸡的屠宰性能和器官指数,极显著升高了血清ALT和AST活性,降低血清ALP活性;并造成蛋鸡肺、卵巢及输卵管组织出现不同程度的病理损伤。
The objective of this experiment was to analyze the effects of cyst of fallopian tube on slaughter performance,organ index,serum biochemistry and histopathology of Hy-Line Grey laying hens.Sixteen 54-week-old Hy-Line Grey laying hens from the same feeding environment were selected and divided into control group(CTR,n=9)and cyst of fallopian tube group(CFT,n=7).Hens were slaughtered and serum samples were collected to determine slaughter performance,organ indices and serum biochemical indexes.The results showed as follows:1)Live weight and dressed weight were significantly higher in cyst of fallopian tube group hens compared to the control group(P<0.01),and dressed percentage was significantly higher(P<0.05);but the percentage of carcass was significantly lower(P<0.01).2)In the CFT group,the cecum index,weight and organ index of duodenum,jejunum and ileum were all highly significantly lower than that in the CTR control group(P<0.01),while the cecum weight and the index of ovary were significantly lower than CTR group(P<0.05).3)The activity of serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were significantly higher(P<0.01),and the activity of serum alkaline phosphatase(ALP)were extremely significantly lower in cyst of fallopian tube group compared to the control group(P<0.01).4)Cyst of fallopian tube caused different degrees of pathological damage to the lungs,ovaries and oviducts of laying hens,such as extensive hemorrhage in the lungs and the alveolar cavity of the lungs filled with large amounts of red exudate;capillary congestion and inflammatory cell infiltration in the cortical area of the ovaries;chorionic villus breakage and inflammatory cell infiltration in the plasma membrane layer of the oviducts.In conclusion,cyst of fallopian tube affected the slaughter performance and organ index of laying hens,increased serum ALT and AST activity,decreased serum ALP activity;it also caused different degrees of pathological damage to the lungs,ovaries and oviducts of laying hens.
