“…Menegol et al (2012) reported lower NDF results for BRS Tarumã wheat grown in the State of Rio Grande do Sul than those in this experiment. In general, the CP, NDF, and ADF levels (Tables 2 and 3) found for BRS Tarumã wheat in this study are similar to those reported by Pitta et al (2011) for an experiment conducted in the southwestern portion of the State of Paraná. 2016reported higher HEM (hemicellulose) levels in IPR 126 oat and BRS Tarumã wheat, respectively than those found in this present study.…”

Morphological characteristics, dry matter production, and nutritional values of winter forage and grains were evaluated. This study was conducted from April 24, 2012 to November 7, 2013 in the Western Paraná State University (UNIOESTE), Marechal Cândido Rondon, Brazil. Pastures under one grazing and non-grazing conditions were evaluated under 120 kg N ha-1 fertilization split into two 60 kg N ha-1 treatments. Two pastures received 40 kg N ha-1 three times. IPR 126 oat, BRS Tarumã wheat, and IPR 111 triticale were the test crops. Topdressing with 40 or 60 kg N ha-1 did not change morphological characteristics until 60 d after sowing. Pastures under non-grazing that received 120 kg N ha-1 treatments were taller than the controls, whereas those under grazing that received 80 or 120 kg N ha-1 presented with higher leaf production than did the controls. Total average dry matter (DM) production in 2012 and 2013 was, respectively, 5,275 kg ha-1 and 6,270 kg ha-1 for oat, 3,166 kg ha-1 and 7,423 kg ha-1 for wheat, and 4,552 kg ha-1 and 7,603 kg ha-1 for triticale. Split N fertilization did not cause differences in the levels of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in the forage. Nevertheless, increases in in vitro dry matter digestibility (IVDMD) were observed in oat and wheat receiving 60 kg N ha-1 during the first graze. IVDMD did not change in oat, wheat, and triticale forages receiving 80 or 120 kg N ha-1 during the second graze. Grazing did not affect the nutritional values of wheat and triticale grains, but reduced those of oat. Therefore, the results of the present study suggest that grazing lengthens the crop cycles, and so allow the staggered sowing of summer crops.

“…Also cultivation of barley led to higher profits in all periods. In another study Recent research has sought to develop crop-and grazing-management strategies for dual-purpose crops in other countries (Pitta et al, 2011;Dove and Kirkegaard, 2014). Grazing of winter wheat is a significant beef cattle production strategy in the Southern and Central Plains of the U.S. (Lollata et al, 2017).…”

This study aimed to evaluate the effects of grazing on the agronomic characteristics, grain yield, and presence of the mycotoxins aflatoxins, fumonisins, and zearalenone in IPR 126 oat, BRS Tarumã wheat, and IPR 111 triticale. This study was performed from April 24, 2012 to November 11, 2013 at UNIOESTE's Experimental Farm in southern Brazil. The experimental design was a randomized block in a banded scheme, with four replications. The treatments in the A tracks were the three crops and the B tracks, the treatments: without grazing, one grazing event, or two grazing events. One grazing reduced the productivity of oat by 42.48% and triticale by 28.09% and increased wheat productivity by 24.89%. Two grazings reduced oat productivity by 54.14%, wheat by 40.96%, and triticale by 54.69%. Crops subjected to two grazings should be used for dry matter production for ground cover or partially used for silage when the plant is in the pasty or semi-hard grain stage, as grazing affects the agronomic characteristics and grain yield. The BRS Tarumã wheat, when used in crop-livestock integration systems, should be grazed only once due to increased productivity, while IPR 126 oat and IPR 111 triticale should not be grazed in crop-livestock integration systems for commercial production of grain. Oats from grazed plants should not be added to feeds of poultry in the early stage or pigs in the early and growth stages due to the higher levels of aflatoxins, fumonisins, and zearalenone. Grazing of winter crops increases the length of the crop cycle and grain formation will occur under climatic conditions favorable to the mycotoxins. Therefore, when grains are intended for human consumption, grazing is not recommended, as it increases the possibility of aflatoxins, fumonisins, and zearalenone at levels above the maximum tolerable levels permitted by law. These grains should be supplied to animals only after analysis of the mycotoxin levels present in the grains. ResumoObjetivou-se avaliar os efeitos dos pastejos nas características agronômicas, produtividade de grãos e presença das micotoxinas: aflatoxinas, fumonisinas e zearalenona em grãos de aveia IPR 126, trigo BRS Tarumã e triticale IPR 111. O trabalho foi desenvolvido no período de 24/04/2012 a 21/03/2014 (24º31'56,1''S; 54º01'10.3"O). O delineamento experimental foi em blocos ao acaso em esquema de faixas, com quatro repetições. Os tratamentos nas faixas A foram as três culturas e nas faixas B os manejo:sem pastejo, um pastejo e dois pastejos. O manejo com apenas um pastejo reduziu a produtividade de grãos da aveia em 42,48% e do triticale em 28,09% e aumentou a produtividade do trigo em 24,89%. O manejo com dois pastejos reduziu a produtividade da aveia em 54,14%, do trigo em 40,96% e do triticale em 54,69%. As culturas submetidas a dois pastejos devem ser diferidas para produção de matéria seca para cobertura do solo ou utilizar de forma parcial a planta no estágio de grãos pastosos ou semiduros para silagem, pois o pastejo prejudica as características agronômicas e...
