Resumo: The objective was to analyze the ingestive behavior, forage intake and pasture characteristics when beef heifers are kept exclusively on ryegrass pasture (Lolium multiflorum Lam.) or receiving ground corn grain as supplement (0.9% of body weight (BW )) with or without addition of crude glycerin (0.2% BW). Experimental animals were Angus heifers with initial age and body weight of eight months and 166.2 ± 9.5 kg, respectively. The grazing method was continuous with variable number of animals. The experimental design was completely randomized with repeated measures. Dry matter intake was estimated using chromium oxide as an indicator of fecal output. Heifers ingested a similar amount of dry matter and neutral detergent fiber. Forage intake was 19.0% lower when heifers receiving ground corn grain as supplement with or without addition of crude glycerin and these reduction in dry matter intake of forage provided increase of 38.2% in the stocking rate. Heifers that received crude glycerin as a supplement spent more time in the trough than heifers that received only ground corn grain.

Os animais experimentais foram bezerras Angus com idade e peso inicial de oito meses e 166,2 ± 9,5 kg, respectivamente. O método de pastejo foi o contínuo com número variável de animais. O delineamento experimental foi o inteiramente casualizado com medidas repetidas no tempo. A ingestão de matéria seca foi estimada usando óxido de cromo como indicador de produção fecal. As bezerras ingeriram similares quantidades de matéria seca e fibra em detergente neutro. A ingestão de forragem foi 19.0% menor quando as bezerras recebem grão de milho quebrado como suplemento com ou sem adição de glicerina bruta e essa redução na ingestão de matéria seca de forragem promove aumento de 38,2% na taxa de lotação. Bezerras que recebem glicerina bruta como suplemento permanecem mais tempo no cocho do que bezerras que recebem somente grão de milho quebrado.EDUFU2017-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3505510.14393/BJ-v34n1a2018-35055Bioscience Journal ; Vol. 34 No. 1 (2018): Jan./Feb.; 162-171Bioscience Journal ; v. 34 n. 1 (2018): Jan./Feb.; 162-1711981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/biosciencejournal/article/view/35055/21465Brazil; ContemporaryCopyright (c) 2017 Guilherme Pegoraro Gai, Luciana Pötter, Marta Gomes da Rocha, Maria José de Oliveira Sichonany, Paulo Roberto Salvador, Luiz Gonzaga do Amaral Neto, Dambros de Moura, Lucas Munareto Cadóhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGai, Guilherme PegoraroPötter, LucianaRocha, Marta Gomes daSichonany, Maria José de OliveiraSalvador, Paulo RobertoAmaral Neto, Luiz Gonzaga doMoura, Dambros deCadó, Lucas Munareto2022-02-11T02:28:47Zoai:ojs.www.seer.ufu.br:article/35055Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-11T02:28:47Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
