Resumo: | The efficient use of pasture is associated to knowledge of the interactions between plant and herbivore, which includes the study of different plant characteristics resulting of had been grazed, which are defined by the grazing management, and the grazing strategies of the herbivore. A meta-analysis was made through a data base including eight experiments with the objective of studying and analyse the feeding behavior, displacement patterns, feeding stations use and meals dynamic of beef heifers (n=658) in cool season pastures. Data was stratified in: with or without energy supplement, phenological stages of grass (Vegetative, Pre-flowering, Flowering), shifts and hourly evaluations. The grazing time decreases and other activities time increases when beef heifers receive energy supplement at the level of 0.8% of body weight, keeping rumination time similar. The energy supplement fed for grazing heifers causes them to remain 12 min less at each feeding station. Supplemented heifers consumed 17.0% less forage and 22.2% less leaf blades than exclusively grazing heifers. Average daily gain of supplemented heifers is correlated positively with bite mass and number of steps between feeding stations. The heifers modify their ingestive behavior, bite rate, meal duration and interval between meals, forage selection patterns and number of steps per minute in the phenological stages of grass and evaluation shifts as a mechanism to keep bite mass similar. The grazing activity was concentrated in the afternoon shift, independent of the feeding system and the phenological stages, and in the night shift the longest rumination event occurs. The forage intake rate is independent of supplement intake and pasture phenological stages. |

Foi realizada a análise conjunta de dados provenientes de oito experimentos, com o objetivo de caracterizar o comportamento ingestivo, padrões de deslocamento, uso de estações alimentares e a dinâmica de refeições de novilhas de corte (n = 658), em pastejo de forrageiras de estação fria e recebendo suplemento energético. Os dados foram estratificados em: com e sem o uso de suplemento, estádios fenológicos do pasto (Vegetativo, Pré-florescimento, Florescimento), turnos e horário de avaliação. O tempo de pastejo diminui e o de outras atividades aumenta quando novilhas de corte recebem suplemento energético em nível de 0,8% do peso corporal, mantendo semelhante o tempo de ruminação. O fornecimento de suplemento energético para novilhas em pastejo faz com que essas permaneçam 12 min. a menos em cada refeição alimentar. Novilhas recebendo suplemento consumiram 17,0% a menos de forragem e 22,2% a menos de lâminas foliares que as novilhas exclusivamente em pastejo. O ganho médio diário das novilhas suplementadas está correlacionado de forma positiva com a massa de bocado e o número de passos entre estação alimentar. As novilhas modificam seu comportamento ingestivo, taxa de bocado, duração das refeições e intervalo entre refeições, padrões de seleção da forragem e número de passos por minuto nos estádios fenológicos avaliados e turnos de avaliação como mecanismo para manter semelhante a massa de bocado. A atividade de pastejo foi concentrada no turno da tarde, independente do sistema alimentar e dos estádios fenológicos avaliados, e no turno da noite acontece o evento mais longo de ruminação. A taxa de ingestão de forragem é semelhante, independente do consumo de suplemento e dos estádios fenológicos dos pastos.Fundação de Amparo à Pesquisa do Estado do Rio Grande do Sul - FAPERGSporUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em ZootecniaUFSMBrasilZootecniaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessDeslocamentoEstação alimentarLolium multiflorum Lam.RefeiçõesTaxa de ingestãoTurnos diárioDisplacementFeeding stationMealsIngestive rateCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAPadrões de ingestão e deslocamento de novilhas de corte em pastagens de estação friaPatters of ingestion and displacement of beef heifers in cool season pasturesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRocha, Marta Gomes dahttp://lattes.cnpq.br/1685524901627774Confortin, Anna Carolina Ceratohttp://lattes.cnpq.br/1210558375437584Bremm, Carolinahttp://lattes.cnpq.br/5026756555102333Quadros, Fernando Luiz Ferreira dehttp://lattes.cnpq.br/9202266292366562Pötter, Lucianahttp://lattes.cnpq.br/0683474086643296http://lattes.cnpq.br/4610458348415311Sichonany, Maria José de Oliveira50040000000260060014258b2c-40f2-45c3-b57b-15e290d7d2f645c6b11b-364b-4bdb-ac8f-f9644889ee8c29070b10-8d47-44ea-99b4-d11d9cca57a125267e89-ebfd-4a9d-9bca-6101dadcc29ff3d1714f-6164-4640-8ac5-b8bc68eab00dca1383e0-88bf-480e-9a99-a339d97da1d1reponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALSichonany, Maria José de Oliveira.pdfSichonany, Maria José de Oliveira.pdfTese de Doutoradoapplication/pdf11076267http://repositorio.ufsm.br/bitstream/1/11568/1/Sichonany%2c%20Maria%20Jos%c3%a9%20de%20Oliveira.pdf943ac412c1d547a0f765741ca5efb249MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
