RESUMO Esta pesquisa foi conduzida com o objetivo de avaliar a produtividade de dois genótipos de trigo de duplo propósito, BRS Tarumã e BRS Umbu, submetidos ao pastejo com vacas em lactação. O delineamento experimental foi o inteiramente ao acaso, com dois tratamentos (genótipos), três repetições (piquetes) e medidas repetidas no tempo (pastejos). Avaliaram-se a precocidade, a composição estrutural dos trigos, as produções de forragem e de biomassa de lâminas foliares, as taxas de acúmulo diário de forragem e de lâminas foliares, a taxa de lotação, as ofertas de forragem e de lâminas foliares, a eficiência de pastejo, o consumo aparente e a produção de grãos. O trigo mais precoce para produção de forragem foi o BRS Umbu. Houve diferença para a produção de forragem (3196 vs. 4143kg MS/ha) e de lâminas foliares (2281 vs. 3205kg MS/ha) para os genótipos BRS Umbu e BRS Tarumã, respectivamente. Valores similares foram encontrados para taxa de lotação (2,26UA/ha); eficiência de pastejo (52,26%), consumo aparente (2,91%) e produção de grãos (1716kg/ha). O genótipo BRS Tarumã é o mais indicado para o manejo de duplo propósito em condições de pastejo com vacas em lactação. Palavras-chave: cereais de inverno, forragem, grãos, Triticum aestivum ABSTRACT The objective of this research was to evaluate the productivity of two dual-purpose wheat genotypes BRS Tarumã and BRS Umbu under grazing with lactating cows. The experimental design was completely randomized, with two treatments, three replications (paddocks) and repeated measures (grazing cycles).Studied variables were early growth, the structural composition of wheat, forage production, leaf blade biomass, the stocking rate, the herbage and leaf blade allowance, the grazing efficiency, the herbage intake and grain yield. The earliest genotype for forage production was the BRS Umbu. Differences in herbage yield between BRS Umbu and BRS Tarumã genotypes (3196 vs. 4143kg DM/ha)

“…These differences may be related to climate conditions and plant development stages. MARIANI et al (2012) studied the performance of winter cereals on the residue of perennial forage and summer crops and found no significant difference for NDF and ADF in black oat as a succession crop to a legume or grass species. However, NDF and ADF were higher with soybean as predecessor (460 and 237 g kg -1 DM, respectively) ------------------------------------------------------------------------ -------------------------------------------------------------------- ---------------------------------------------------------------- --------------------------------------------------------------------- ------------------------------------------------------------------- ---------------------------------------------------------------------------Coefficient--------------------------------------------------------------------------- when compared with corn (427 and 220 g kg -1 MS, respectively).…”

The present study assessed the influence of the preceding crop (crotalaria or corn) on the bromatological, digestibility and microbiological aspects of the EMBRAPA 139 black oat hay (Avena strigosa) cultivar. A randomized block design was used, with subplots divided according to time, whereby the preceding crop (crotalaria or corn) was allocated to the main plot and hay storage times (baling, 30, 60 and 90 days of storage) to the subplots, with five repetitions. Crotalaria as predecessor resulted in lower indigestible fiber and higher protein contents in black oat hay, both in acid detergent, as well as higher pH. Corn as the preceding crop provided better hay digestibility due to lower neutral detergent insoluble protein content and higher in vitro neutral detergent fiber digestibility. The preceding crop did not significantly affect the drying time of forage and the microorganism population.

“…In southern Brazil one of the biggest limitations to livestock farming is forage lack in period from fall to early winter; a time when the summer forage species reduced productivity, and winter forage species are still not satisfactorily developed. In addition to traditionally alternatives used in critical period, such as annual ryegrass and oat pastures, silage and hay, dual-purpose cereals like wheat can provide forage to animals and grains in same crop (MARIANI et al, 2012). Moreover, wheat is considered a forage with good nutritional quality, when grazed on vegetative growth (HARRISON et al, 2011;HARRISON et al, 2014).…”

Crop-livestock system implies in the balance of appropriate animal foraging, minimizing effects on grain production on the same crop season. This study aims to assess canopy heights (20 and 30 cm) and cuts number (no cut, 1, 2 and 3 cuts) effects on wheat productivity and bromatological composition of forage, and grain yield of BRS Umbu and BRS Tarumã cultivars. Regardless cuts number and cultivars, 30 cm provided higher forage productivity (1032 and 1348 kg DM ha-1) than 20 cm (554 and 909 kg DM ha-1), for BRS Umbu and Tarumã, respectively, in average crop seasons. For both cultivars and crop seasons, mean values of 26% crude protein, 55% neutral detergent fiber and 26% acid detergent fiber were obtained. At 20 cm no difference in grain yield was observed as a function of cuts number with 3780 kg ha-1 for BRS Umbu, in average crop seasons and 4306 kg ha-1 in 2014, for BRS Tarumã. However, at 30 cm, the grain yield was penalized at least in 30% as a result only third cut. These results indicate that wheat as dual-purpose can be employed in southern Brazil in grazing systems in forage shortage times and then produce grains without yield penalties as a function to the management used.
