Resumo: | This research was carried out to evaluate the effects of pregnancy, number of fetuses and feed restriction on nutrients intake and digestibility and on ruminal rate passage. Twenty-four ewes were used at 90, 110 and 130 pregnancy days distributed among treatments according to the number of fetuses. They received balanced diet or restricted diet at 15% of energy and protein requirement. Ewes with two fetuses on feed restriction had more dry matter intake than those with one fetus. At 130 day there was the highest dry matter and neutral detergent fiber intake. Twin-pregnant ewes showed the highest nutrient digestibility, except for fiber fraction. Feed restriction caused the smallest dry matter intake. Ruminal rate passage increased in late pregnancy.KEYWORDS: feed management; number of fetuses; prepartum; sheep. |

Foram utilizadas 24 ovelhas aos 90, 110 e 130 dias de gestação, divididas entre os tratamentos em função do número de fetos. Os animais receberam dietas balanceadas ou restritas em 15% nos requisitos de energia e proteína. Ovelhas com dois fetos submetidas à restrição nutricional consumiram mais matéria seca que aquelas com um feto. Aos 130 dias de gestação, houve maior consumo de matéria seca e fibra em detergente neutro. Ovelhas de gestação dupla apresentam maior digestibilidade dos nutrientes, exceto nas frações fibrosas. A restrição alimentar acarretou menor ingestão de matéria seca. A taxa de passagem ruminal aumenta ao final da gestação.PALAVRAS-CHAVE: manejo alimentar; número de fetos; ovinos; pré-parto.Universidade Federal de Goiás2012-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisaapplication/downloadtext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/1882610.5216/cab.v13i4.18826Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 4 (2012); 429-439Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 4 (2012); 429-4391809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/18826/12700https://revistas.ufg.br/vet/article/view/18826/12701https://revistas.ufg.br/vet/article/view/18826/15433Macedo Junior, Gilberto de L.Benevides, Yuri IdaCampos, Warley EffrenBorges, IranRodriguez, Norberto MarioFerreira, Deborah Alvesinfo:eu-repo/semantics/openAccess2012-12-14T21:39:04Zoai:ojs.revistas.ufg.br:article/18826Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:53.945505Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
