MORPHOLOGICAL CHANGES OF EGGS AND REPRODUCTIVE ORGANS OF LAYING HENS WITH TRICHOMONIASIS

Egg productivity and morphological parameters of domestic laying hens eggs are an objective criterium of their wellbeing. Decreased egg production and egg defects may be the only sign of the latent course of trichomoniasis in poultry. We investigated the level of productivity and morphological indicators of eggs in the conditions of a mini poultry farm of laying hens with spontaneous trichomoniasis. It was found that 20% of hens stopped laying. Decrease in egg production by 29.16%, various defects in the texture of the shell (calcareous bumps, deformations, lack of a calcified layer) and the internal content of the egg (thinning of the protein part, presence of hemorrhages) were found in laying hens with preserved egg production. Severe forms of obstructive salpingitis and atrophic ovariitis with the absence of ovulatory follicles in the altered ovarium were diagnosed in poultry with cessation of egg production as a result of trichomoniasis infestation by post-mortem examination.
