| Popis: | The objective of this study was to evaluate the effects of benzoic acid (BA) and essential oils (EO) on cellular and humoral immune response, morphology, gene expression, antioxidant capacity in the jejunal mucosa, and cecal content microbiota in weaned piglets and growth performance from the nursery to finishing phase. One hundred and twenty barrows were weaned and assigned to three treatments in a randomized block design: basal diet without additives (NC), basal diet with antibiotics (PC), and basal diet with 0.3% BA and EO (BA+EO). The pigs were weighed 0, 42, 84, and 132 days into the experiment. The incidence of diarrhea was assessed daily in the nursery phase. On days 1, 3, and 9, blood samples were collected. On day 9, these animals were euthanized to collect jejunal samples and cecal content. In the nursery phase, the PC piglets showed a greater body weight (BW) and average daily gain (ADG) and a lower feed conversion ratio (FCR) compared to the NC group, but similar levels to the BA+EO group (P |
