The effect of a commercial organic acid (OA) product on BW loss (BWL) during feed withdrawal and transportation, carcass yield, and meat quality was evaluated in broiler chickens. Two experiments were conducted in Brazil. Commercial houses were paired as control groups receiving regular water and treated groups receiving OA in the water. Treated birds had a reduction in BWL of 37 g in experiment 1 and 32.2 g in experiment 2. In experiment 2, no differences were observed in carcass yield between groups. Estimation of the cost benefit suggested a 1:16 ratio by using the OA. In experiment 3, conducted in Mexico, significant differences on water consumption, BWL, and meat quality characteristics were observed in chickens that were treated with the OA (P < 0.05). These data suggest this OA product may improve animal welfare and economic concerns in the poultry industry by reducing BWL and improving meat quality attributes. © 2014 Poultry Science Association Inc.

In the present study, a series of experiments was conducted to evaluate the ability of a commercial probiotic culture (FloraMax, IVS-Wynco LLC, Springdale, AR) to reduce Salmonella enterica serovar Heidelberg (SH) in chicks and turkey poults. In experiments 1 and 2, chicks were randomly assigned to treatment groups and then challenged via oral gavage with SH. Chicks were treated 1 h following SH challenge with the probiotic culture via oral gavage. At 24 and 72 h posttreatment, cecal tonsils and ceca were collected for recovery and enumeration of enteric Salmonella Heidelberg, respectively. In experiment 3, day-of-hatch turkeys were randomly assigned to treatment groups and then challenged via oral gavage with SH. Poults were treated 1 h following challenge with the probiotic via oral gavage. At 24 and 72 h post probiotic treatment, cecal tonsils and ceca were collected for recovery and enumeration of enteric SH, respectively. The probiotic culture significantly reduced the incidence of SH in cecal tonsils at both time points in chicks in both experiments (P < 0.05). These data demonstrate that administration of probiotic 1 h post SH challenge significantly reduced the incidence of SH recovery from cecal tonsils of chicks compared with controls 24 and 72 h following treatment. Similarly, probiotic treatment resulted in significant reductions in the concentrations of SH within the ceca in both experiments. Although similar significant results were observed at both 24 and 72 h in experiment 3, it was clear that poults were more susceptible to SH colonization than chicks. Overall, a Lactobacillus-based probiotic significantly reduced Salmonella enterica serovar Heidelberg in chicks and turkey poults. © 2011 Poultry Science Association Inc. Source
