Resumo: | The dry matter intake, ingestive behavior and displacement patterns were evaluated on beef heifers exclusively on pasture or receiving oats grain daily ( frequent ) or from Monday to Friday ( infrequent ) in "Vegetative" and "Reproductive" phenological stages of Alexandergrass (Urochloa plantaginea Link.). The grazing method was continuous with a variable number of animals. The experimental design was completely randomized, in a factorial 3 x 2 arrangement (three supplementation frequency and two phenological stages). Forage intake was estimated using chromium oxide as an indicator of fecal output. Forage intake was greater for heifers exclusively on pasture and daily supplemented (2.91% of body weight (BW)) than for heifers receiving infrequent supplementation (2.00% of BW). Forage intake was greater in "Vegetative" than "Reproductive stage. Changes in supplementation frequency and phenological stages of Alexandergrass caused variation in the use of feeding stations. The grazing time was diminished and the bites were heavier when heifers received daily supplementation. The bite weight and grazing time were similar in phenological stages while the bite rate decreased in the reproductive stage. Changes in supplementation frequency and in phenological stages of alexandergrass modify the feeding behavior and forage intake of beef heifers. |

O método de pastejo foi continuo com número variável de animais. O delineamento experimental foi inteiramente casualizado, arranjado em esquema fatorial 3 x 2, três frequências alimentares e dois estádios fenológicos. A ingestão de matéria seca foi estimada por meio de técnica do óxido de cromo como indicador da produção fecal. Animais em pastagem exclusiva de papuã e com suplemento diário consumiram mais forragem (2,91% do PC em MS) que os animais que receberam suplemento de forma infrequente (2,00% do PC em MS). O consumo de forragem foi maior no estádio Vegetativo que no Reprodutivo . O uso das estações alimentares é modificado em resposta as frequências de suplementação e aos estádios fenológicos. Novilhas que receberam suplemento diariamente pastejaram por menor tempo e colheram bocados mais pesados. O peso de bocado e o tempo de pastejo foram semelhantes nos estádios fenológicos do pasto enquanto a taxa de bocado diminuiu no estádio reprodutivo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaAveia brancaEstações alimentaresEstádio fenológicoÓxido de cromoUrochloa plantagineaOatFeeding stationPhenological stageChromic oxideUrochloa plantagineaCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAEfeito de frequências de suplementação no comportamento ingestivo, padrão de deslocamento e ingestão de matéria seca por novilhas de corteThe effects of several supplementation frequencies on ingestive behavior, displacement patterns and dry matter intake by beef heifersinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRocha, Marta Gomes dahttp://lattes.cnpq.br/1685524901627774Pötter, Lucianahttp://lattes.cnpq.br/0683474086643296Montagner, Denise Baptaglinhttp://lattes.cnpq.br/4505594312712884http://lattes.cnpq.br/4610458348415311Sichonany, Maria José de Oliveira50040000000240050030050030014258b2c-40f2-45c3-b57b-15e290d7d2f645c6b11b-364b-4bdb-ac8f-f9644889ee8c0a396763-33d6-4c4b-9646-cfa9ccf2739f8a8f6777-bde0-41e7-b83b-b685d42a6d55info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALSICHONANY, MARIA JOSE DE OLIVEIRA.pdfapplication/pdf1257229http://repositorio.ufsm.br/bitstream/1/10799/1/SICHONANY%2c%20MARIA%20JOSE%20DE%20OLIVEIRA.pdf29799e8094bf37d7f437fed5386639c3MD51TEXTSICHONANY, MARIA JOSE DE OLIVEIRA.pdf.txtSICHONANY, MARIA JOSE DE OLIVEIRA.pdf.txtExtracted texttext/plain113497http://repositorio.ufsm.br/bitstream/1/10799/2/SICHONANY%2c%20MARIA%20JOSE%20DE%20OLIVEIRA.pdf.txtd9987e2fe09bfc24c650248e15b6d110MD52THUMBNAILSICHONANY, MARIA JOSE DE OLIVEIRA.pdf.jpgSICHONANY, MARIA JOSE DE OLIVEIRA.pdf.jpgIM Thumbnailimage/jpeg5696http://repositorio.ufsm.br/bitstream/1/10799/3/SICHONANY%2c%20MARIA%20JOSE%20DE%20OLIVEIRA.pdf.jpg23bcebf4752969560e6afeaa60ec49b2MD531/107992022-01-10 11:11:55.837oai:repositorio.ufsm.br:1/10799Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-01-10T14:11:55Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |

description |
The dry matter intake, ingestive behavior and displacement patterns were evaluated on beef heifers exclusively on pasture or receiving oats grain daily ( frequent ) or from Monday to Friday ( infrequent ) in "Vegetative" and "Reproductive" phenological stages of Alexandergrass (Urochloa plantaginea Link.). The grazing method was continuous with a variable number of animals. The experimental design was completely randomized, in a factorial 3 x 2 arrangement (three supplementation frequency and two phenological stages). Forage intake was estimated using chromium oxide as an indicator of fecal output. Forage intake was greater for heifers exclusively on pasture and daily supplemented (2.91% of body weight (BW)) than for heifers receiving infrequent supplementation (2.00% of BW). Forage intake was greater in "Vegetative" than "Reproductive stage. Changes in supplementation frequency and phenological stages of Alexandergrass caused variation in the use of feeding stations. The grazing time was diminished and the bites were heavier when heifers received daily supplementation. The bite weight and grazing time were similar in phenological stages while the bite rate decreased in the reproductive stage. Changes in supplementation frequency and in phenological stages of alexandergrass modify the feeding behavior and forage intake of beef heifers. |
