Descrição: dc.descriptionThis study aimed to evaluate the responses in performance, egg quality, and health of internal organs of laying hens of Hisex White lineage. The birds were provided with diets supplemented with organic minerals (OM) + tributyrin, associated or not with a mixture of organic acids (benzoic formic, citric, and phosphoric), compared to a control treatment containing zinc bacitracin (28 ppm). In total, 160 laying hens of the commercial Hisex White lineage of 68 w and an average weight of 1.735 ± 0.025 kg were distributed in 40 experimental plots. The study employed a completely randomized design, with five treatments and eight replications/treatment. The experimental period was divided into seven production cycles of 21 days, totalling 147 experimental days. The variables analysed were egg production and loss, feed intake, mean egg weight, egg mass, feed conversion, and internal and external quality variables of eggs. At the end of the experimental period, the final weight of the birds was measured to evaluate the relative weight of liver and kidneys. No significant effect of the treatments on the productive performance and internal and external quality of the eggs was evident. The association of organic minerals with a mixture of organic acids and tributyrin did not influence the productive performance and internal and external quality of the shell of Hisex White laying hens in the period from 68 to 89 weeks of age.-
