Effects of Antisol Supplementation on the Laying Performance and Egg Quality of Hubbard Laying Hens during the 30–40-Week-Old Period

This study was conducted to evaluate the effects of dietary Antisol supplementation on the laying performance and egg quality of Hubbard laying hens during the 30- to 40-week-old period. The trial was arranged in a completely randomized design (CRD) with three treatments and ten replicates: T1, no Antisol supplementation (control); T2, Antisol supplemented at 1.5 g/L of drinking water; and T3, Antisol supplemented at 2.0 g/L of drinking water. The experiment was carried out from March 2026 to June 2026 at Thong Nhat poultry farm, Dong Nai province. The results showed significant differences (P < 0.05) in laying performance and egg quality among treatments. Antisol supplementation exerted a positive effect on both performance and egg quality in Hubbard hens. Hens supplemented with 2.0 g/L Antisol (T3) achieved a higher daily laying rate (94.57%) than those in T1 and T2 (81.12% and 92.74%, respectively). Mean egg weight reached 55.29 g in T1, 54.45 g in T2, and 57.21 g in T3. These findings indicate that supplementing 2.0 g Antisol per liter of drinking water produced the best laying performance and egg quality. A second trial, arranged as a completely randomized design with five treatments and ten replicates using 100 eggs, was also conducted to evaluate storage effects. Yolk color improved with storage time in treatments G3, G4, and G5 (11.0, 10.8, and 10.0, respectively) compared with treatments G1 and G3 (11.2); this difference was statistically significant (P < 0.05). All treatments scored above 7 for yolk color, meeting the standard for good egg quality. For Haugh unit (HU), G1 and G2 showed higher values (84.0 and 77.6, respectively) than G3, G4, and G5 (75.2, 71.8, and 70.1, respectively) (P < 0.05). All treatments met the standard of 60–70 HU or above for Grade-A eggs. Overall, Antisol proved to be an effective feed additive that improves laying performance and egg quality, thereby increasing the economic efficiency of Hubbard layer-hen farms during the production period.+
