Effects of salpingitis simulation on the morphology and expression of inflammatory-related genes of oviduct in laying hens.

ABSTRACT: This study was conducted to simulate salpingitis of laying hens by observing the morphology and expression of inflammatory genes in the oviduct. A total of one hundred twenty 81-wk-old Roman Pink laying hens in good physical condition without the oviduct disease with an average egg production rate of 76% were fed a basal diet for 2 wks and then randomly allocated into 4 groups (6 replicates/group, 5 birds/replicate). The experimental treatments were as follows: 1) Control group (treated with PBS); 2) Organic chemical reagent (OCR) group; 3) Lipopolysaccharide (LPS) group; 4) LPS + OCR group. First, the chickens were kept upside down to make ectropion and exposure of the apertura uterinae; then prepared reagents were poured into the uterine part of the fallopian tube by using the chicken va
