ABSTRACT: Traditional livestock productivity is hard to estimate, since it depends on a gamut of animal production indicators that are difficult to measure for many farms. Thus, we propose an analytical method for estimating productivity and understanding the importance of animal production indicators under different full-cycle cattle production systems in Brazil. To evaluate the impact of these indicators, equations were derived from a comutational model of herd evolution for estimating the output parameters of the system as follows: productivity per hectare (PH) and offtake rate (COR), as a function of the indicators; calving rate (CR), mating age (AM), age of slaughter (AS) and stocking rate (SR). For this analysis, twenty-seven scenarios (simulation data) of low to high productivity were used, resulting from the combination of the following factors and levels: 1) calving rate of 50, 65 and 80 %; 2) mating age of heifers of one, two and three, years of age; and 3) age at slaughter of one, two and three year old steers. The scenario with the highest impact for each parameter and the indicator of highest impact for each scenario were identified for the production conditions in the region. Under most scenarios, a reduction in mating age had a greater impact on the productivity indexes compared to a reduction in slaughter age. Appropriate management of available technologies enables farmers to compare the marginal impacts of specific indicators on full-cycle production systems for beef cattle.

ABSTRACT.
The goal of our study was to improve Tannat Vitis vinifera L. grape and wine composition, by achieving vine balance in a humid climate. We tested under-trellis cover crops (UTCC) compared to a standard floor management of alleyway cover crops and under-vine herbicide. This strategy was tested in combination with variable planting density over three growing seasons in Southern Uruguay. Two factors were evaluated in a split plot design with five replicates. Treatments were, (1) UTCC (full cover of the vineyard soil with tall fescue (Festuca
arundinacea Shreb)) versus conventional alleyway tall fescue with 1.0 m wide weed-free strips under the trellis, and (2) two spacings between vines in the row (0.8 vs 1.5 m). To avoid excessive vine water stress, supplemental irrigation was used during water deficit periods. Shoot growth rate, mid-day stem water potential, berry size and berry composition were monitored over the season as well as final yield, cluster and pruning weights. Results showed that UTCC reduced vegetative growth as expressed by pruning weight/m while closer PD resulted in greater vegetative growth parameters. UTCC reduced vine vegetative growth to recommended values of pruning weight per m of row under both plating densities. It also reduced berry size, cluster weight and bunch rot incidence as well as increased total soluble solids and anthocyanin concentration in grapes compared to the standard herbicide treatment. The use of UTCC with supplemental irrigation, showed promise for achieving vine balance in high vine capacity conditions.
