“…In the fourth grazing cycle, NDF and ADF values were lower in irrigated treatments. Therefore, the irrigation collaborated to the formation of new growth cells; being these with lower cellular content, consequently lower levels of NDF and ADF (BARBERO et al, 2010). The NDF and ADF values are within the literature, from 70 to 85% and 30 to 45%, respectively (BOW & MUIR et al, 2010;NERES et al, 2012;SANCHES et al, 2015).…”

ABSTRACT:The pasture irrigation has expanded, mostly in small areas in order to boost the production system, along with the use of soil improvement techniques and high-productivity grasses. Thus, this study, carried out on a small dairy farm property, aimed to evaluate the productivity, botanical composition and nutritive value of Tifton 85 with different nitrogen (N) doses, in the presence and absence of irrigation. The experimental design was a randomized block in a split-plot design with four replications, plots Non-irrigated and Irrigated. The subplots consisted of nitrogen doses: 25 kg ha -1 cycle -1 of N, 50 kg ha -1 cycle -1 of N, 75 kg ha -1 cycle -1 of N and 100 kg ha -1 cycle -1 of N. The irrigation increased the productivity in an average of 3,626.5 kg ha -1 cycle -1 , with higher leaf stem ratio of 1.3, increasing the crude protein content of the pasture. The productivity responded quadratically to nitrogen fertilization with increases up to 84 kg N ha -1 cycle -1 with slight linear decrease of dead matter. There were linear increments of crude protein and digestibility "in vitro" of dry matter in function of applied nitrogen.

“…Consequently, its cellulose content was the lowest (27.69%), significantly different (P<0.05) when compared to other cultivars. Lignin is indigestible, and therefore has negative effects on the forage (BARBERO et al, 2010). Cellulose content varied between 26.24% and 35.79%, but stayed within the 20-40% range described by Van Soest (1994).…”

The goal of this work was to evaluate the growth dynamics and chemical characteristics of the upper and lower strata of summer perennial grasses under a four cuts system. The experiment was conducted in a randomized block design, composed of 28 treatments in a factorial arrangement of 7x4, with four repetitions. The cultivars evaluated were Star Grass, Coast-cross, Tifton 68, Tifton 85, Jiggs, Roxinha and Quicuio. Each cultivar was cut when it reached 95% light interception. The cultivars Jiggs and Tifton 68 had the highest (P<0.05) accumulation of dry biomass ha -1 during the four cuts, with productions of 21,348 and 21,016 kg ha -1 , respectively. The ash content varied (P<0.05) among species and times of cutting for both strata. Cellulose contents were significantly different in the upper stratum, with the highest concentrations found in cvs. Quicuio and Tifton 68 (39.12% and 38.07%, respectively). We found the highest levels of lignin (P<0.05), for both strata, in cv. Quicuio. Cultivars Jiggs and Tifton 68 were the most appropriate for a management system of four cuts, displaying good chemical composition and high productivity.

“…Esses resultados evidenciam o efeito das baixas temperaturas sobre essa espécie tropical, sendo observado que suas folhas sofreram danos severos a partir do mês de abril, contribuindo para seu desaparecimento. Em regiões de clima quente, tem sido observado participação estável dessa espécie na composição da pastagem, o que pode ser atribuído à característica de seus pontos de crescimento localizaram-se próximo à superfície do solo, dificultando sua remoção pelo bocado dos animais (Barbero et al, 2010). Um dos fatores que afeta sua participação na consorciação é a altura da gramínea, sendo que quanto maior a altura da gramínea no momento do pastejo, menor tem sido a manutenção da leguminosa na massa de forragem (Andrade et al, 2006).…”

RESUMOO consórcio de gramíneas e leguminosas é uma alternativa promissora para o aumento da produção de forragem, sendo que a associação das duas espécies tem melhorado o valor nutritivo da dieta dos ruminantes. Objetivou-se avaliar o rendimento de massa seca (MSF) e a composição química da forragem de missioneira-gigante, consorciada ou não com leguminosas perenes. Foi utilizado delineamento experimental de blocos completos casualizados, com três repetições, em parcelas subdivididas no tempo. Nas parcelas foram testados três tratamentos: missioneira-gigante (MG); MG + amendoim-forrageiro (AF); e MG + lótus serrano (LS) e as subparcelas foram constituídas por sete épocas de corte da pastagem, de novembro/2011 a novembro/2012. Houve interação entre tratamentos e épocas de corte para todas as variáveis. O consórcio aumentou a MSF nos cortes de primavera-verão. A participação das leguminosas na composição botânica da pastagem variou ao longo do período, sendo que o LS reduziu de 39 para 10%. A participação do AF na produção de forragem manteve-se próximo a 8%, à exceção do inverno, quando não acumulou massa seca. A composição química da forragem foi influenciada pela composição botânica, com aumento no teor de proteína bruta e da digestibilidade na MG+LS. Os resultados indicam que AF e LS são leguminosas promissoras para consorciação com MG. Palavras-chave: Axonopus catharinensis, Arachis pintoi, Lotus uliginosusProduction, botanical composition and chemical composition of "giant missionary" pasture intercropped with perennial legumes ABSTRACT Mixed pastures is a viable alternative to increase forage production and the association of two species (legume and grass) in the same area can improve the nutritional value of animal diet. To evaluate the dry mass forage and chemical composition of giant missionary (GM) pasture (Axonopus catharinensis Valls.) intercropped or not with perennial legume species it was conducted this experiment. The randomized complete block design was used, with three replications in a split plot scheme. In the plots were tested three treatments: MG single crop; MG + forage peanut (FP) (Arachis pintoi cv. Bushel); and MG + Lotus serrano" (LS) (Lotus uliginosus cv. SCS 313 Serrano). The subplots were composed of seven forage cutting times from November 2011 to November 2012. There was interaction between the experimental factors for all variables. The GM intercropping with LS or FP increased the dry matter forage during the spring and summer period. The botanical composition changed during the evaluation period, with reduced participation of LS from 39 to 10%. The participation of FP forage remained at around 8%, but in the winter, this species did not growth. The chemical composition of the forage was influenced by the botanical composition. The higher crude protein content and digestibility was observed in GM + LS. The results indicate that FP and LS show high potential in for intercropping with GM, although the persistence of LS require further assessment.
