Out of 300 Desi laying hens examined, ovaries of only 12 (4%) birds showed two pathological conditions i.e. oophoritis (2.6%) and degenerative ovarian follicles (1.3%). In oophoritis, the ovaries were haemorrhagic and congested. The infilteration of heterophils was noted in the follicular wall. In the other condition, degenerative ovarian follicles, caseous mass was found in flaccid follicle. The sloughed granulose cells were found to be accumulated in some of ovaries causing obliteration of follicular lumen. The biometrical studies of ovaries were also carried out. In oophoritis, five cases were found positive for Salmonella (S) pullorum and S. gallinarum, two cases for Mycoplasma (M) gallisepticum, while only one sample was found positive for Egg Drop Syndrome (EDS) 76 infection. In degenerative ovarian follicles infection, out of 4 cases, two were positive for salmonella and only one for mycoplasma infection.
