A study was carried out to determine the effect of 3 supplementation products (Vitamin, Vitamin + Mineral, Vitamin+Amino acid) in drinking water on egg performance and quality of laying hens. A total of 2,880 Hisex Brown laying hens at the 43 weeks of age were randomly distributed in a completely randomized design experiment, with 4 treatments and 3 replicates. Each replicate consisted of a line with 60 pens (4 birds/pen). The experimental data was collected during 7 weeks. Treatments used (1) Control (Cont): Basal diet without any supplementation product in drinking water, (2) Vit: Basal diet+Vitaral (Vitamin), (3) VitM: Basal diet + Aminovit (Vitamin+Mineral), (4) VitA: Basal diet+Elecamin (Vitamin+Amino acid), all supplements were supplied in drinking water at 2ml/l. The results showed that, average daily feed intake in Vit treatment was slight lower than the others treatments. But a little improvement hen day production and feed conversion ratio in all supplemented treatments compared to control group. There was non-significant difference in egg weight and egg mass of all treatments. The supplemented diets showed higher proportion of double york eggs, and reduced the broken egg compared with control group. There was no significant effect of treatments on egg shape index, York and albumen index, but there was a light improvement of egg shell thickness in supplemented groups compared with control group, the higher yellow color of egg York was found in chicken eggs fed VitM treatment. The conclusion of this experiment is supplementation of vitamin, vitamin and mineral or amino acid products in drinking water at 2 ml/l could lightly improve hen day production, egg shell thickness, and egg york color.
