Resumo: | This study was conducted at Sheep Laboratory of the Federal University of Santa Maria (UFSM), and to evaluate nutrient intake, performance, feeding behavior, the quantitative and qualitative characteristics of Tifton-85 pasture (Chapter I) as well as carcass characteristics, tissue composition and non-carcass of lambs weaned constituents finished in different feeding systems (Chapter II). Twenty-six male, weaned, castrated lambs cross-bred from Texel and Ile de France breeds were used. The treatments were the following: T1 - Containment: Concentrate + Tifton 85 hay (ad libitum) (CONF); T2 - Tifton-85 pasture + concentrate (ad libitum) (PSA) and T3 - Tifton-85 pasture + concentrate (1.0% body weight) (PSR). The animals were slaughtered when they reached the body condition (BC) pre-established 3.0. The consumption, performance, feeding behavior, carcass characteristics, the commercial cuts and non-carcass of the lambs were influenced (P<0.05) by different feeding systems. In treatments where the energy level in the diet was higher (CONF and PSA) animals showed DM, OM and CP higher, but lower NDF (P<0.05). Performed better (P<0.05). But the feeding behavior of the parameters of the lambs have changed (P<0.05) through the lower intake of NDF, but without compromising the rumination activity. Also showed superiority (P <0.05) on carcass traits, heavier commercial cuts (P<0.05) and the least developed gastrointestinal tract (P<0.05) compared to the lambs of PSR. However, the body measurements in vivo and on carcass, the tissue composition of the palette and the quantitative and qualitative characteristics of Tifton-85 pasture were not affected (P>0.05) by different systems terminus, except for the conformation and leg width (P<0.05) in lambs PSR. Thus, the confinement, the pasture with supplementation ad libitum or restricted characterized as viable alternatives of technical and productive point of view for finishing lambs weaned. Introducing potential for production carcasses with excellent quality, meeting the demands of actual consumer market. |

Foram utilizados 26 cordeiros, desmamados, machos castrados, cruza Texel x Ile de France. Os tratamentos foram: T1 Confinamento: Concentrado + Feno de tifton-85 (ad libitum) (CONF), T2 Pastagem cultivada de tifton-85 + Concentrado (ad libitum) (PSA) e T3 Pastagem cultivada de tifton-85 + Concentrado (1,0% do peso corporal) (PSR). Os animais foram abatidos quando atingiram a condição corporal (CC) pré-estabelecida 3,0. O consumo, o desempenho, o comportamento ingestivo, as características de carcaça, os cortes comerciais e os constituintes não-carcaça dos cordeiros foram influenciados (P<0,05) pelos distintos sistemas de alimentação. Nos tratamentos onde o nível energético na dieta foi superior (CONF e PSA) os animais apresentaram consumo de MS, MO e PB superior, mas inferior de FDN (P<0,05). Obtiveram melhor desempenho (P<0,05). Porém os parâmetros do comportamento ingestivo dos cordeiros foram alterados (P<0,05), através do menor consumo de FDN, mas sem comprometer a atividade de ruminação. Também apresentaram superioridade (P<0,05) nas características de carcaça, cortes comerciais mais pesados (P<0,05) e o trato gastrintestinal menos desenvolvido (P<0,05) em relação aos cordeiros da PSR. No entanto, as medidas corporais in vivo e na carcaça, a composição tecidual da paleta e as características quanti-qualitativas (P>0,05) da pastagem de tifton-85 não foram influenciadas (P>0,05) pelos diferentes sistemas de terminação, com exceção a conformação e largura de perna (P<0,05) para os cordeiros da PSR. Desta forma, o confinamento, a pastagem com suplementação à vontade ou restrita caracterizam-se como alternativas viáveis do ponto de vista técnico e produtivo para terminação de cordeiros desmamados. Apresentando potencial para produção de carcaças com excelente qualidade, atendendo as demandas do mercado consumidor atual.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaIngestãoGanho de pesoCortes comerciaisRendimentoComportamento ingestivoIngestionWeight gainCommercial cutsYieldIngestive behaviorCNPQ::CIENCIAS AGRARIAS::ZOOTECNIATerminação de cordeiros suplementados em pastagem de tifton-85 ou confinados com dieta de alto grãoTermination of lambs supplemented in tifton-85 pasture or confined with high-grain dietinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPires, Cleber Cassolhttp://lattes.cnpq.br/5811435302893655Carvalho, Sergiohttp://lattes.cnpq.br/9114677690912835Corrêa, Gladis Ferreirahttp://lattes.cnpq.br/9046591323954835http://lattes.cnpq.br/3118528420386553Simões, Fernanda de Souza Britto50040000000240050030050030038c91256-5016-4aa4-a3bc-9059a5224a0e04ae7c99-0023-4b72-8740-5caaf1055b1ff0299130-04b7-4746-be0e-50b9638664286c29fe3f-6919-4535-8083-68567842884finfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALSIMOES, FERNANDA DE SOUZA BRITTO.pdfapplication/pdf1198582http://repositorio.ufsm.br/bitstream/1/10877/1/SIMOES%2c%20FERNANDA%20DE%20SOUZA%20BRITTO.pdfed1a50ad04d16d9b78151db141bf0f97MD51TEXTSIMOES, FERNANDA DE SOUZA BRITTO.pdf.txtSIMOES, FERNANDA DE SOUZA BRITTO.pdf.txtExtracted texttext/plain212994http://repositorio.ufsm.br/bitstream/1/10877/2/SIMOES%2c%20FERNANDA%20DE%20SOUZA%20BRITTO.pdf.txt7392c11936cb50feaa0c343c3b645e63MD52THUMBNAILSIMOES, FERNANDA DE SOUZA BRITTO.pdf.jpgSIMOES, FERNANDA DE SOUZA BRITTO.pdf.jpgIM Thumbnailimage/jpeg5157http://repositorio.ufsm.br/bitstream/1/10877/3/SIMOES%2c%20FERNANDA%20DE%20SOUZA%20BRITTO.pdf.jpg3331aedcef8b7271cbf3b0aa9abed625MD531/108772022-06-01 10:52:23.183oai:repositorio.ufsm.br:1/10877Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-06-01T13:52:23Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
