Resumo: | The study was carried out the Department of Animal Science of the Federal University of Santa Maria, with the objective to investigate the effect of the supply of diets with different levels of neutral detergent fiber (NDF) on the nutrients intake, daily milk yield (MP), milk composition (MC) and ingestive behavior of lactating ewes. Eighteen ewes, proceeding from the alternated crossing between Texel and Ile de France breeds were used, housed indoors in individual cages. The animals were distributed on three treatments: 34, 43 and 52% NDF in the diet, in dry matter basis (DM) to consist in the treatments. Equal protein diets, with 13% of PB (crude protein) content, in DM basis, was composed of total mixed ration of corn ensilage (Zea mays L.), and a concentrate mixture based on fragmented corn, soybean bran (Glycine max L.) and mineral mixing. The food supply was ad libtum, done twice a day, in set up times at 8:30 AM and 4:30 PM. An entirely randomized design was used, with three treatments and six repetitions each. The results were submit of the analysis of variance and regression study. The addition of increasing in NDF levels result in quadratic effect (P<0,05) on the intake of dry matter (DMI), organic matter (OMI), crude protein (CPI), ethereal extract (EEI), total carbohydrates (TCHOI), and non-structural carbohydrates (NSCI), neutral detergent fiber (NDFI) and acid detergent fiber (ADFI), expresses in kg/day, % PV and g/kg PV0,75. The maximum DMI corresponded to 42.7% NDF level in the diet. Do not significant effect (P>0.05) of the diets on the variations of average weight daily gain (GMD). The body score condition (CC) presented quadratic behavior (P<0.05). Quadratic effect was verified (P<0.05) on the milk yield in function of the treatments, that was maximum with 39.8%NDF level of in the diet. The crude protein milk (CP) values presented quadratic variation (P<0,05). The milk fat contents (Gord), express in g/day, and the density, had diminished linearly with the NDF increasing in the diet. The total solids contents, express in g/day, density, 3.5% and 4% fat corrected milk yield had varied in quadratic way (P<0.05), in function of the treatments. The stage of lactating influenced on milk production (P<0.05), resulting quadratic effect for 34% and 43% NDF levels, and linear effect for the 52%NDF level in the diet. Quadratic effect (P<0.05) were verified in the resting, rumination, intake and total chewing times in function of the NDF levels in the diets. The feeding and rumination efficiency of the NDF is increased with the increase of the level of this fraction in the diet. Lactating ewes confined present greater concentration of activity of feeding during the day and rumination during the night. |

Foram utilizadas 18 ovelhas, provenientes do cruzamento alternado entre as raças Texel e Ile de France, confinadas em baias individuais. Os animais foram distribuídos aleatoriamente em três tratamentos: 34, 43 e 52% de FDN na dieta, em base na matéria seca (MS). As dietas, isoprotéicas, contendo 13% de PB (MS) foram compostas por mistura completa de silagem de milho (Zea mays L.), concentrado a base de milho triturado e farelo de soja (Glycine max) e premix mineral. O arraçoamento foi feito ad libtum, duas vezes ao dia, em horários preestabelecidos, às 8:30 e 16:30 horas. Utilizou-se um delineamento experimental inteiramente casualizado, com três tratamentos e seis repetições cada. Os dados foram interpretados através de análises de variância e regressão. Houve influência do nível de FDN da dieta (P<0,05) sobre os consumos de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), carboidratos não-estruturais (CNE), carboidratos totais (CHT) e cinzas (CIN), expressos em Kg/dia, em %PV e em g/Kg PV0,75, que apresentaram comportamento quadrático. O máximo consumo de MS correspondeu ao nível de 42,7% de FDN na dieta. Não houve efeito significativo (P>0,05) das dietas sobre as variações de peso vivo (GMD). A condição corporal final (CC2) evoluiu quadraticamente (P<0,05). Verificou-se efeito quadrático (P<0,05) da produção de leite em função dos tratamentos, que foi máxima com um nível de 39,8% de FDN na dieta. Os teores de PB do leite variaram quadraticamente (P<0,05). O teor de gordura do leite (Gord), expresso em g/dia, e a densidade, diminuíram linearmente (P<0,05) com o incremento de FDN na dieta. Os teores de sólidos totais (ST), expressos em g/dia, densidade (DENS), leite corrigido para 3,5% de gordura (LCG3,5) e 4% de gordura (LCG4) e leite corrigido para sólidos totais (LCST) variaram de modo quadrático (P<0,05), em função dos tratamentos. O estágio da lactação influenciou a produção de leite dos animais (P<0,05), resultando efeito quadrático para os níveis 34% e 43% de FDN, e linear para o nível de 52% de FDN na dieta. Houve efeito quadrático (P<0,05) do nível de FDN da dieta sobre os tempos despendidos em alimentação, ruminação, ócio e de mastigação total (TMT). A eficiência de alimentação e ruminação da FDN é incrementada com o aumento do nível desta fração na dieta. Ovelhas em lactação mantidas confinadas apresentam maior concentração de atividade de alimentação durante o período diurno e de ruminação durante o noturno.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaConcentradoForragemIngestãoLeiteOvinosRuminaçãoConcentrateFiberIntakeMilkSheepCNPQ::CIENCIAS AGRARIAS::ZOOTECNIADesempenho e comportamento ingestivo de ovelhas em lactação alimentadas com dietas contendo diferentes níveis de fibra em detergente neutroPerformance and ingestive behavior of lactating ewes fed diets containing different levels of neutral detergent fiberinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPires, Cleber Cassolhttp://lattes.cnpq.br/5811435302893655Carvalho, Sergiohttp://lattes.cnpq.br/9114677690912835Carvalho, Nelcy Madruga dehttp://lattes.cnpq.br/3921306054399639http://lattes.cnpq.br/1431262295463134Hübner, Cristiano Haetinger50040000000240050030030030038c91256-5016-4aa4-a3bc-9059a5224a0e38be003c-c984-4648-833a-08a0a7ebf589af5bc6ee-f0e5-4602-a027-ab9b11f1e8cc205b6f3a-caa7-4559-9cde-54cd3c8396f6info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCRISTIANO HUBNER.pdfapplication/pdf379406http://repositorio.ufsm.br/bitstream/1/10694/1/CRISTIANO%20HUBNER.pdff14f1cfffc1c518bbbf14999a782cf86MD51TEXTCRISTIANO HUBNER.pdf.txtCRISTIANO HUBNER.pdf.txtExtracted texttext/plain92209http://repositorio.ufsm.br/bitstream/1/10694/2/CRISTIANO%20HUBNER.pdf.txtd38e3c745d304601e418a758750e1333MD52THUMBNAILCRISTIANO HUBNER.pdf.jpgCRISTIANO HUBNER.pdf.jpgIM Thumbnailimage/jpeg4837http://repositorio.ufsm.br/bitstream/1/10694/3/CRISTIANO%20HUBNER.pdf.jpg81e14801f13acc760bc6b1844b9349a5MD531/106942023-01-06 15:00:58.535oai:repositorio.ufsm.br:1/10694Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-01-06T18:00:58Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
