Resumo: | The objective of this research was to evaluate of three grazing systems (GS) with Elephant grass (EG) + Italian ryegrass (IR) + spontaneous growing species (SGS); EG + IR + SGS + Forage peanut (FP); and EG + IR + SGS + Red clover (RC), in order to use the area in rotational grazing during all agricultural year. EG was planted in rows with a distance of 4 m each one of them. In the cool-season, IR was sowed between rows of EG; RC was sowed and the FP who has found established since 2006 was preserved on respectively GS. Experimental design was completely randomized with three treatments (GS), two replicates (paddocks) and independent evaluations (grazing cycles). For evaluation, were used lactating Holstein cows receiving 1% of BW day-1 feed supplement concentrate. The pre and post forage mass parameters, botanical and structural composition, forage production and stocking rate were evaluated. Samples were collected by the handplucking method to analyze the organic matter, mineral matter, crude protein (CP), neutral detergent fiber (NDF), in situ organic matter digestibility (ISOMD), in situ dry matter digestibility (ISDMD) of forage. Eight grazing cycle were performed during the experimental period (357 days). The values of forage production and stocking rate were 15.03, 16.33, 17.03 t ha-1 and 3.57, 3.52 and 3.65 animal unit ha-1, respectively grazing systems. Grazing systems involving grasses and forage legumes in different cycles provide use of the area during the agricultural year in rotational grazing with dairy cattle. SGS increased significantly (P≤0.05) over in GS without forage legume. Higher value of CP, ISOMD and lower of NDF for GS mixed with forage legumes. Considering the herbage mass, stocking rate and nutritive value, the pastures mixed to forage legumes showed better performance. |

O CE foi estabelecido em linhas afastadas a cada 4 m. No período hibernal fez-se o estabelecimento do AZ entre as linhas do CE; o TV foi semeado e o AM que já se encontrava estabelecido desde 2006, foi preservado, considerando os respectivos tratamentos. O delineamento experimental foi o inteiramente casualizado, com três tratamentos (SF), duas repetições (piquetes) e avaliações independentes (ciclos de pastejo). Para avaliação foram utilizadas vacas da raça Holandesa em lactação, que receberam suplementação alimentar com concentrado à razão de 1% do peso corporal dia-1. Foram avaliados parâmetros de massa de forragem pré e pós pastejo, composições botânica e estrutural, produção de forragem e taxa de lotação. Para analisar a matéria orgânica, matéria mineral, a fibra em detergente neutro (FDN), a proteína bruta (PB), a digestibilidade in situ da matéria seca (DISMS) e a digestibilidade in situ da matéria orgânica (DISMO) da forragem, foram coletadas amostras de pastejo simulado. Durante o período experimental (357 dias) foram efetuados oito ciclos de pastejo. Os valores de produção de forragem e de taxa de lotação foram de 15,03; 16,33; 17,03 t ha-1 e 3,57; 3,52 e 3,65 UA ha-1, respectivamente para os sistemas forrageiros. Sistemas forrageiros, envolvendo gramíneas e leguminosas de diferentes ciclos, proporcionam a utilização da área durante todo o ano agrícola em pastejo rotativo com bovinos leiteiros. Houve aumento significativo (P≤0,05) para ECE na pastagem sem leguminosa. Foram observados maiores valores de PB, DISMO e menores de FDN para os SF consorciados com leguminosas. Considerando a massa de forragem, a taxa de lotação e o valor nutritivo, as pastagens consorciadas com leguminosas forrageiras apresentaram melhor desempenho.Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em ZootecniaOlivo, Clair Jorgehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783027J6Viegas, Juliohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4782452P7Carvalho, Paulo César de Facciohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4782265J0Diehl, Michelle Schalemberg2012-09-122012-09-122012-02-27info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfDIEHL, Michelle Schalemberg.
