| Abstract: | 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. |
