Resumo: | The objective of this study was to evaluate the biometry and carcass characteristics of finished Santa Inês crossbred sheep grazed on tropical grass pastures during the dry season. The study was carried out at the Grupo de Estudos em Forragicultura (GEFOR/UFRN), in Macaíba - RN, Brazil. Four forage treatments were evaluated: Brachiaria brizantha cvs. Marandu e Piatã, Panicum maximum cvs. Aruana e Massai. The 2.88 ha-area used was divided in two blocks of 1.44 ha; each one was composed of four plots corresponding to each cultivar, and each plot was subdivided into six paddocks with an area of 0.06 ha. The pastures were managed under intermittent stocking with seven days of occupation and 35 days of rest, with variable stocking rate. No significant difference was observed in the biometric measurements evaluated in the animals, except for chest width in which animals kept in Marandu pastures obtained higher values than those in the Aruana cultivar. The lowest values of average daily gain, final weight and weight at slaughter values were observed in the animals kept in Aruana cultivars. Cut weights of the shoulder, the loins, short legs/shanks and ribs were higher in the animals kept in Marandu grass and lower in those kept in the Aruana grass; however, no differences were observed for the yield of the cuts and for the biometric measurements of the carcass. The evaluated pasture cultivars did not modify the finished sheep carcasses, however, the lower forage mass from Aruana grass pastures in the dry season affected animal performance and the sheep carcass composition. |

O trabalho foi realizado no Grupo de Estudos em Forragicultura (GEFOR/UFRN), em Macaíba – RN, Brasil. Os tratamentos avaliados foram quatro forrageiras: Brachiaria brizantha cvs. Marandu e Piatã, Panicum maximum cvs. Aruana e Massai. A área utilizada foi de 2,88 ha dividida em dois blocos de 1,44 ha, onde cada um desses foi constituído de quatro parcelas correspondente a cada cultivar, e cada parcela subdivida em seis piquetes com área de 0,06 ha. Os pastos foram manejados sob lotação intermitente com sete dias de ocupação e 35 dias de descanso, com taxa de lotação variável. Não houve diferença significativa nas medidas biométricas avaliadas nos animais, exceto para a largura do peito, em que os animais mantidos nos pastos da cultivar Marandu obtiveram valores maiores que aqueles da cultivar Aruana. Os menores valores de ganho médio diário, peso final e peso aoabate foram observados nos animais mantidos na cultivar Aruana. Os pesos dos cortes paleta, lombo, pernil e costela foram maiores nos animais mantidos no capim-marandu e menores naqueles mantidos no capim-aruana, porém não foram observadas diferenças para o rendimento dos cortes e para as medidas biométricas na carcaça. As cultivares avaliadas não modificam as carcaças de ovinos terminados em pasto, porém a menor massa de forragem dos pastos da cultivar Aruana na época seca comprometem o desempenho animal e a composição das carcaça de ovinos.EDUFU2017-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3678110.14393/BJ-v34n1a2018-36781Bioscience Journal ; Vol. 34 No. 1 (2018): Jan./Feb.; 172-179,Bioscience Journal ; v. 34 n. 1 (2018): Jan./Feb.; 172-179,1981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/36781/21466Brazil; ContemporaryCopyright (c) 2017 Thiago Felipe de Medeiros Trindade, Gelson dos Santos Difante, Leonardo Santana Fernandes, Itânia Maria Medeiros de Araújo, Emmanuel Lievio de Lima Véras, Marcone Geraldo Costa, Maria Gabriela da Trindade Silva, Mariana Campelo Medeiroshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessTrindade, Thiago Felipe de MedeirosDifante, Gelson dos SantosFernandes, Leonardo SantanaAraújo, Itânia Maria Medeiros deVéras, Emmanuel Lievio de LimaCosta, Marcone GeraldoSilva, Maria Gabriela da TrindadeMedeiros, Mariana Campelo2022-02-11T02:34:34Zoai:ojs.www.seer.ufu.br:article/36781Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-11T02:34:34Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
