Objective: The aim of this study was to estimate genetic parameters for 305-day cumulative milk yield and components, growth, and reproductive traits in Guzerá cattle. Methods: The evaluated traits were 305-day first-lactation cumulative yields (kg) of milk (MY305), fat (FY305), protein (PY305), lactose (LY305), and total solids (SY305); age at first calving (AFC) in days; adjusted scrotal perimeter (cm) at the ages of 365 (SP365) and 450 (SP450) days; and adjusted body weight (kg) at the ages of 210 (W210), 365 (W365) and 450 (W450) days. The (co)variance components were estimated using the restricted maximum likelihood method for single-trait, bi-trait and tri-trait analyses. Contemporary groups and additive genetic effects were included in the general mixed model. Maternal genetic and permanent environmental effects were also included for W210. Results: The direct heritability estimates ranged from 0.16 (W210) to 0.32 (MY305). The maternal heritability estimate for W210 was 0.03. Genetic correlation estimates among milk production traits and growth traits ranged from 0.92 to 0.99 and from 0.92 to 0.99, respectively. For milk production and growth traits, the genetic correlations ranged from 0.33 to 0.56. The genetic correlations among AFC and all other traits were negative ( 0.43 to 0.27). Scrotal perimeter traits and body weights showed genetic correlations ranging from 0.41 to 0.46, and scrotal perimeter and milk production traits showed genetic correlations ranging from 0.11 to 0.30. The phenotypic correlations were similar in direction (same sign) and lower than the corresponding genetic correlations. Conclusion: These results suggest the viability and potential of joint selection for dairy and beef traits in Guzerá cattle, taking into account reproductive traits.

The use of co-products from the fruit agroindustry as a source of bioactive molecules presents economic advantages, since these compounds are highly available and inexpensive. Therefore, the present study aimed to evaluate their qualitative chemical composition followed by multivariate analysis, and to correlate the results with those of the cytotoxicity tests. The non-polar metabolic profiles of the leaves of seven commercial pineapple (Ananas comosus (L.) Merr.) cultivars were investigated by using GC?MS. Twenty-seven metabolites were identified from the seven hexanic extracts. Multivariate analysis (Hierarchical Cluster Analysis, Principal Component Analysis and Partial Least Squares) revealed significant differences in the metabolic fingerprint of the different cultivars. Overall, the hexanic extracts of the seven cultivars of pineapple leaves showed promising antitumor activity against the six tumor lines tested (colon, leukemia, prostate, astrocytoma, breast and cervix). Correlation of the chemometric data, qualitative analysis, and cytotoxic tests allowed us to determine the possible biomarkers responsible for each specific antitumor activity. This study demonstrates a great valuation potential of a co-product little explored in the agroindustry of foods through the prospection of biologically active compounds. |
