Abstract: Sugarcane outstands as an important renewable source of energy with expected steady production growth. However, expansion of sugarcane is critical, since the environmental performance of ethanol may be affected by GHG emissions derived from LUC. On the other hand, livestock farming currently practiced in Brazil is mainly extensive, occupying large areas and showing low productivity levels. Hence, in order to sustain the increase of ethanol production, mitigation of iLUC effects should be a priority on sugarcane expansion strategies. Integration of ethanol and beef cattle production can be part of this strategy by contributing to reduction of GHG emissions and improving land use management. This study made a comparative evaluation of the environmental profile of integrating ethanol and beef cattle production, considering different scenarios. The production chains were connected in such a way that the land used for biofuels would be converted from pre-existing extensive pasture, thereby minimizing iLUC and food vs. fuel competition. Results show that integrated production have better environmental performance for most LCA categories analyzed, but the relative differences between scenarios do not exceed 10%. The potential for mitigating GHG emissions through ethanol production and intensification of cattle husbandry became evident when they replace fossil resources and extensive production. Finally, it is important to remark that such integration can largely contribute to avoid iLUC and to support the achievement of the Brazilian emissions target from the Paris Agreement, especially through the increase of bioenergy participation in the Brazilian energy matrix and the restoration of degraded pasture areas.

The objective of this study was to evaluate the effect of heterosis on the lactation curve components of Girolando cattle obtained by fitting different mathematical models. Data consisted of 258,891 test day milk yield records of the first lactation from 37,965 cows of Minas Gerais State (Brazil) between 1998 and 2014. Those cows were from the Holstein breed (H), Gyr breed (G) and six genetic cross-breedings of Holstein × Gyr, (1/4H, 3/4G (1/4H); 3/8H, 5/8G (3/8H); 1/2H, 1/2G (1/2H), 5/8H, 3/8G (5/8H); 3/4H, 1/4G (3/4H); 7/8H, 1/8G (7/8H)), which is officially named as Girolando breed in Brazil. The Wood’s linear model (WDlin), Wood’s non-linear model (WDnlin), Wilmink’s model (WL) and Ali and Schaeffer’s model (ASH) were used for estimating the peak milk yield (PY), time to peak yield (PT), 305-day milk yield (TMY) and four different persistency measures (P, P2:1, P3:1 and P3:2). Regardless of the fitted model, the highest estimates of PY and TMY were for the H group. The heterosis effect was significant (p < .001) for TMY and all components of the lactation curve, except for P2:1. Girolando cattle presented a heterosis effect of 12.30% and 13.03% for PY and TMY, respectively. The magnitude of heterosis effect was larger for PT (24.18%), whereas the different persistency measures presented the smallest magnitude of heterosis values. The producers may use the different genetic groups to benefit from the heterosis mainly for the time to peak, peak yield and 305-day milk yield.HIGHLIGHTS• Girolando cows in production systems in Brazil has shown positive results. • The greater productive efficiency may be because of heterosis on the production.• Thus effect of heterosis on lactation curve can contribute to the improvement of the production system.
