Resumo: | The objective was to evaluate the effect of different levels of energy supplementation on carcass characteristics, meat quality and non integrant parts of carcass of heifers, finishing in Tifton 85 pasture. Thirty-two heifers slaughtered at 30 months of age were used, originating from the rotating crossing between the Charolais and Nellore breeds. The experimental design was completely randomized. The animals were distributed uniformly according to weight and genetic group at the following levels of supplementation: not supplemented; 0.4; 0.8 and 1.2 kg DM 100-1 kg body weight. Supplemented heifers, regardless of the level, presented higher slaughter weight, empty body weight and internal fat weight than heifers without supplementation. The hot and cold carcass weights, cold carcass yield, absolute weights of forequarter, sidecut, sawcut, muscle and fat, thickness of cushion, compactness of carcass, fat production in kg and the weight of were higher for heifers than 0.8 and 1.2%, compared to not supplemented. Higher muscle tissue weights were observed for 1.2%, in relation to not supplemented and 0.4%. Heart weight was higher for heifers fed 0.4 or 1.2%, in relation to not supplemented. Heifers with 1.2% of supplementation presented higher liver weight than those not supplemented. Heifers receiving 0.8% of supplementation presented higher values of L* and b* staining than heifers finished exclusively in Tifton 85 pasture. Higher levels of energy supplementation promote increases in the quantitative carcass traits of heifers, finishing in Tifton 85. |

Foram utilizadas 32 novilhas abatidas com 30 meses de idade, oriundas do cruzamento rotativo entre as raças Charolês e Nelore. O delineamento experimental foi o inteiramente casualizado. Os animais foram distribuídos uniformemente quanto ao peso e grupo genético nos seguintes níveis de suplementação: sem suplementação; 0,4; 0,8 e 1,2 kg MS 100-1 kg peso corporal. Novilhas suplementadas, independentemente do nível, apresentaram maior peso de abate, peso de corpo vazio e peso de gorduras internas, que novilhas sem suplementação. Os pesos de carcaça quente e fria, rendimento de carcaça fria, pesos absolutos de dianteiro, costilhar, traseiro, músculo e gordura, espessura de coxão, compacidade da carcaça, produção de gordura, em kg e o peso de pulmão foram superiores para novilhas que receberam 0,8 e 1,2%, em relação às não suplementadas. Maiores pesos de tecido muscular foram observados para 1,2%, em relação às sem suplementação e 0,4% de suplementação. O peso do coração foi superior para as novilhas alimentadas com 0,4 ou 1,2% em relação as sem suplementação. Novilhas com 1,2% de suplementação apresentaram maior peso de fígado que as não suplementadas. Novilhas que receberam 0,8% de suplementação apresentaram maiores valores de coloração L* e b* que novilhas sem suplementação. Níveis mais elevados de suplementação energética promovem incrementos nas características quantitativas da carcaça de novilhas terminadas em Tifton 85.Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPqporUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em ZootecniaUFSMBrasilZootecniaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessFêmea bovinaÓrgãos vitaisPeso de carcaçaQualidade de carneBovine femaleCarcass weightMeat qualityVital organsCNPQ::CIENCIAS AGRARIAS::ZOOTECNIACaracterísticas pós-abate de novilhas terminadas em pastagem de Tifton 85 recebendo níveis crescentes de suplementação energéticaPost slaughter characteristics of heifers finished in Tifton 85 pasture receiving growth levels of energy supplementationinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisAlves Filho, Dari Celestinohttp://lattes.cnpq.br/2140386505744337Cattelam, Jonatashttp://lattes.cnpq.br/1695252434498963Pires, Cleber Cassolhttp://lattes.cnpq.br/5811435302893655http://lattes.cnpq.br/3346359762546821Silva, Marcelo Ascoli da500400000002600e80896c6-107c-4173-83b3-2f62810c5f9cf048e66b-3c32-43a9-88a1-21a0f05c66e959d58428-8327-4783-864d-90c86f39c2940a9da74f-5bbe-4fd1-bf3b-e3c85e430c17reponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGZOOTECNIA_2018_SILVA_MARCELO.pdfDIS_PPGZOOTECNIA_2018_SILVA_MARCELO.pdfDissertação de Mestradoapplication/pdf1024268http://repositorio.ufsm.br/bitstream/1/14476/1/DIS_PPGZOOTECNIA_2018_SILVA_MARCELO.pdfbc1f8f9feafeb6845fd3aa1241534f66MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

The objective was to evaluate the effect of different levels of energy supplementation on carcass characteristics, meat quality and non integrant parts of carcass of heifers, finishing in Tifton 85 pasture. Thirty-two heifers slaughtered at 30 months of age were used, originating from the rotating crossing between the Charolais and Nellore breeds. The experimental design was completely randomized. The animals were distributed uniformly according to weight and genetic group at the following levels of supplementation: not supplemented; 0.4; 0.8 and 1.2 kg DM 100-1 kg body weight. Supplemented heifers, regardless of the level, presented higher slaughter weight, empty body weight and internal fat weight than heifers without supplementation. The hot and cold carcass weights, cold carcass yield, absolute weights of forequarter, sidecut, sawcut, muscle and fat, thickness of cushion, compactness of carcass, fat production in kg and the weight of were higher for heifers than 0.8 and 1.2%, compared to not supplemented. Higher muscle tissue weights were observed for 1.2%, in relation to not supplemented and 0.4%. Heart weight was higher for heifers fed 0.4 or 1.2%, in relation to not supplemented. Heifers with 1.2% of supplementation presented higher liver weight than those not supplemented. Heifers receiving 0.8% of supplementation presented higher values of L* and b* staining than heifers finished exclusively in Tifton 85 pasture.
