Organic acids are carboxylic acids with the R-COOH structure and are released naturally through metabolic events. Organic acids are widely used as preservatives in poultry feed, especially to keep mold and other microorganisms under control. Organic acids are grouped according to the number of carbon atoms and carboxyl groups in their structures. Purpose of this study was to investigate the effects of increasing amounts of organic acid addition (Lactic acid, Formic acid, Propionic acid and Acetic acid) to laying hen rations on some parameters of egg quality, productivity and intestinal villi. In the study, 180 Akbay white laying hens at the age of 40 weeks were distributed to 3 groups and 6 replicates. Ad libitum drinking water was added to CN group chickens, 1 L/1000 L and 2 L/1000 L organic acid (85% Formic acid, Propionic acid, 80% Lactic Acid, 80% Acetic Acid) was added to the water of OAM1 and OAM-2 group chickens and it was given 30 days. There was no statistically significant difference in the length measurement of intestinal duodenum, jejunum and ileum villi between the control and the groups to which organic acid was added (P>0.05). There was no lesion in the histopathological examination of the intestines. Egg productivity parameters such as egg weight, yolk color index, albumen height, Haugh unit and strength were found to be statistically significant between the groups (P<0.05). As a result, it is thought that it would be appropriate to add organic acid to the drinking water of laying hens for shell quality and quality egg production.
