Abstract: We tested the efficacy of a commercial product (Glucan-MOS®) derived from yeast Saccharomyces cerevisiae, containing two combined products, Beta-1,3-1,6 glucans and mannans on the growth, feed efficiency, stress and innate immune responses of juvenile pacu (Piaractus mesopotamicus) after a stressful handling and bacterial inoculation. For this, we evaluated the serum cortisol and plasma glucose levels, the respiratory activity of leukocytes, the serum lysozyme levels, as well as the number of circulating erythrocytes and leukocytes of fish fed during 30 days with diets containing increased levels of Glucan-MOS (0.0, 0.1, 0.2, 0.4 and 0.8%). The supplementation of 0.1% improved weight gain, feed conversion and the protein efficiency ratio compared to a control diet. The 0.2 and 0.4% Glucan-MOS® diets were sufficient to increase the respiratory burst of leukocytes and lysozyme activity, the number of thrombocytes, neutrophils and monocytes in the blood after a stressful handling and bacterial challenge, and minimized stress response as shown by decreased cortisol and glucose levels when compared to the control. The results of this work reinforce the benefits of the adoption of feeding strategies including combination of both Beta-1,3-1,6 glucans and mannans as a dietary supplement in periods prior to intensive management. The 30-day period was sufficient to stimulate growth performance, improve nutrient utilization, minimize stress response and modulate innate immunity responses.

The search for a more efficient beef cattle production system has led to the use of considerable number of traits as selection criteria. As such, the success of breeding programs relies on accurate estimates of genetic parameters of economic important traits. Thereby, the aim of this study was to estimate the genetic parameters for rib eye area (REA), backfat thickness (BF), rump fat thickness (RFT), days open (DO) and calving interval (CI) measured on 4,100 Nelore cattle. The data set is Vera Cruz Ranch, a cattle ranch that participates in the Brazilian National Association of Breeders and Researchers (ANCP). Heritabilities and correlations were estimated using univariate and bivariate linear mixed model. The model included contemporary groups (year and season of birth, sex and management group), cow age at calving (in classes and as linear and quadratic covariate) as fixed effects, and genetic and residual components as random effects. The estimates of heritability for REA (0.38), BF (0.34), RFT (0.34), DO (0.18), and CI (0.21) indicate that they could be improved by direct selection. Rib eye area shows moderate correlation (0.36 and 0.38) with BF and RFT. The backfat thickness measured in the rib and the rump showed a high genetic correlation with each other (0.81). REA presented a correlation of -0.09 and -0.14 with CI and OD, respectively. Similarly, the genetic correlations between CI, DO and BF (-0.11 and -0.20); and CI, DO and RFT (-0.10 and -0.16) were negative. Although the genetic correlation between carcass and reproductive efciency traits is low there are still genes that affect both traits as such the genetic selection for one might decrease the other. On the other hand, the correlation between CI and DO was of high magnitude (0.43), confirming the simultaneous influence of a group of genes on both traits. Genetic selection for carcass and reproductive traits efficiency traits is feasible, however, it is necessary to include both groups as a selection criterion. This is because, genetic selection for carcass will present low response in reproductive efficiency characteristics and vice versa.
