Becoming globally competitive has proved more and more to be a challenge not only for Brazil, but for all countries. However, knowing the dynamics of international trade, to verify whether the export agenda is in line with the world demand can be a step towards decision-making for the attaining of better efficiency for Brazil?s international insertion. The objective of this study was to analyze the insertion of Brazil?s agribusiness in the international agricultural trade, and to identify the ranking of its products in comparison with the world, considering the 2005-2007 and 2015-2017 triennia, based on the methodology suggested by Fajnzylber (1991). It was possible to identify that the situation is favorable, since 46.51% of the country?s export total value in agribusiness products, in the 2015-2017 triennium, is composed of 150 products classified in an optimum situation according to the proposed methodological approach. |

Autoregressive (AR) and random regression (RR) models were fitted to test-day records from the first three lactations of Brazilian Holstein cattle with the objective of comparing their efficiency for national genetic evaluations. The data comprised 4,142,740 records of milk yield (MY) and somatic cell score (SCS) from 274,335 cows belonging to 2,322 herds. Although heritabilities were similar between models and traits, additive genetic variance estimates using AR were 7.0 (MY) and 22.2% (SCS) higher than those obtained from RR model. On the other hand, residual variances were lower in both traits when estimated through AR model. The rank correlation between EBV obtained from AR and RR models was 0.96 and 0.94 (MY) and 0.97 and 0.95 (SCS), respectively, for bulls (with 10 or more daughters) and cows. Estimated annual genetic gains for bulls (cows) obtained using AR were 46.11 (49.50) kg for MY and -0.019 (-0.025) score for SCS; whereas using RR these values were 47.70 (55.56) kg and -0.022 (-0.028) score. Akaike information criterion was lower for AR in both traits. Although AR model is more parsimonious, RR model assumes genetic correlations different from the unity within and across lactations. Thus, when these correlations are relatively high, these models tend to yield to similar predictions; otherwise, they will differ more and RR model would be theoretically sounder. |
