“…Moreover, the leaves and stems presented higher digestibility (IVDMD). Tonato et al (2014) with black oats and annual ryegrass under intermittent stocking, and grazing strategy based on 95% LI and fixed rest period (30days), registered that in ryegrass pastures managed with 95% LI the proportion of leaves is larger and the proportion of stems is lower.…”

The main system for feeding cattle in Brazil is the forage-based. It happens due to low cost and high potential of forage production, which can be widely explored in a tropical climate country. Although, the nutritive value of the forage oscillates according to the grazing management. The success in production is related to the three main stages: herbage growth, consumption by grazing animals and conversion into animal product, maximizing profitability while providing sustainability. Thus, the objective with this literature review is to address detailed information on how grazing management can affect qualitative indicators of forage plants.

“…The greater range of grazing was observed in Barjumbo ryegrass intercropped, probably due to the lowest rate of daily accumulation, and by Barjumbo ryegrass has not presented a good production yield. Tonato et al (2014) conducted a study with black oat pasture and Italian ryegrass light interception and uncovered that single Common ryegrass cutting interval was of 18 days, but when it was intercropped with black oat this range rose to 23.7 days, and finally the single oat presented 32.3 days interval. High: output with 50% of input height; Low: output with 30% of input height.…”

The objective of this study was to define the input height to grazing and evaluate forage production of Italian ryegrass (Lolium multiflorum Lam.) cv. Barjumbo and cv. Common associated or not with oat black forage (Avena strigosa Schreb) cv. IAPAR 61, submitted to two post-grazing. Treatments consisted of a 4x2 factorial design, totaling eight treatments with three replications, being evaluated common and Barjumbo ryegrass, single and mixed with black oat in two highs of post-grazing residue: High: 50% of input height; Low: 30% of input height. Single Common ryegrass and combined with black oat obtained higher production than Barjumbo cultivate, and greater accumulation rate only when intercropped with black oat. Leaf blades production did not differ among cultivars. Stems production was low to Barjumbo cultivar. Black oat production was higher when associated with Barjumbo. Input height to Italian ryegrass cultivars with 95% light interception was 26.86 cm to Barjumbo and 28.75 cm to common cultivar, and when combined with black oat 34.01 cm and 32.48 cm, respectively. Key words: Avena strigosa Schreb. Barjumbo. Stem. Leaf blade. Lolium multiflorum. ResumoO objetivo deste estudo foi definir a altura de entrada para pastejo e avaliar a produção de forragem do azevém (Lolium multiflorum Lam.) cv. Barjumbo e do azevém comum (Lolium multiflorum) consorciados ou não com aveia (Avena strigosa Schreb) cv. IAPAR 61 submetidos a resíduos de pastejo. Os tratamentos foram constituídos de um bifatorial 4x2, totalizando oito tratamentos com três repetições, sendo avaliados os azevém comum e Barjumbo solteiros e consorciados com aveia preta em duas alturas de resíduo pós-pastejo: Alto: 50% da altura de entrada; Baixo: 30% da altura de entrada. O azevém comum solteiro e no consórcio com aveia obteve maior produção que o cultivar Barjumbo, e maior taxa de acúmulo apenas quando consorciado com aveia. A produção de folhas não diferenciou entre os cultivares, apenas a produção de colmo que foi menor para o cultivar Barjumbo. A produção de aveia foi maior quando consorciada com o cultivar Barjumbo. A altura de entrada para os cultivares de azevém com 95% de interceptação luminosa foi de 26,86 cm para o Barjumbo e 28,75 cm para o comum, e quando consorciados com aveia de 34,01 cm e 32,48 cm, respectivamente. Palavras-chave: Avena strigosa Schreb. Barjumbo. Colmo. Lâmina foliar. Lolium multiflorum.

“…Integrated crop-livestock systems (ICLS) can contribute to cattle farming, mainly through the use of inactive areas (Tonato et al, 2014), which can be occupied with winter pastures (Silveira et al, 2017). In grass-feeding systems, fluctuations in forage availability throughout the year make the activity challenging, however, planting forage in idle areas and storing the surplus allows for greater stability (Santos et al, 2010).…”

The search for forage cultivars that provide higher yields with quality in periods of forage shortage, whether in isolated or mixed management, is essential for livestock stability. Thus, the objective was to evaluate the forage performance and nutritive value of rye cultivars mixtures (BRS Progresso, BRS Serrano and Temprano) from different production cycles compared to the isolated management of rye, dual-purpose wheat cvs. (BRS Tarumã and BRS Pastoreio) and black oat cv. Embrapa 139 Neblina as controls. The experiment was conducted at a randomized complete block design, with four rye associations and the isolated cultivation of wheat, oat, and rye. Dry matter (DM) yield and nutritive value, such as content of neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude protein (CP) content were evaluated for each cut and total values. There was difference (P<0.001) in total DM, the highest yield was in single cultivation as well as mixtures with Temprano. BRS Serrano and BRS Progresso and their mixture had lower leaf blade percentage in the total DM. There were differences (P<0.05) in NDF concentration (55.1 to 70.60%), ADF (15.2 to 34.7%), and CP (27.4 to 36.8%) levels along harvests. Among cultivars, Temprano showed the highest proportion of leaf blades and total DM yield.
