Resumo: | The objective of this study was to quantify the non-carcass components of steers and heifers finished in feedlot and fed with high grain diets. Altogether, 45 Charolais and Nellore crossbred cattle of two categories, 21 heifers with an initial age of 32 months and 24 steers with an initial age of 20 months, were used. The animals were fed with diets of 100% concentrate and divided in groups according to the energy source used in the form of rice, white oat, or corn; each diet group had seven heifers and eight steers. The experimental design was completely randomized with a factorial 3 ´ 2 arrangement, using P<0.05. The slaughter weight and empty body weight were higher in animals fed with corn (430.4 and 379.1 kg, respectively) or white oat (449.3 and 378.0 kg, respectively) as compared to animals fed with rice (401.9 and 341.0 kg, respectively). With the exception of heart and abomasum fat, all other adipose tissue deposits were lower in animals fed with rice. The steers showed higher development of internal organs (3.67% versus 3.24%), feet (2.33% versus 2.06%), and total peripheral components (15.9% versus 15.1%), while heifers presented higher total fat deposition (6.45% versus 5.75%), as expressed in relation to empty body weight. Thus, the use of high grain diets based on corn or white oat in the finishing of cattle leads to higher development of internal organs and digestive tract, while feed with rice grain provides less deposition of adipose tissue. |

Utilizaram-se 45 bovinos de duas categorias, sendo 21 novilhas com idade inicial de 32 meses e 24 novilhos com idade inicial de 20 meses, oriundos do cruzamento entre as raças Charolês e Nelore. Os animais receberam dietas de 100% concentrado e foram distribuídos nos tratamentos conforme a fonte energética utilizada, sendo essas: arroz; aveia branca ou milho, sendo utilizados sete novilhas e oito novilhos para cada dieta alimentar. O delineamento experimental foi o inteiramente casualizado, com arranjo fatorial 3 x 2, utilizando P<0,05. Os pesos de abate e de corpo vazio foram superiores nos animais alimentados com milho (430,4 kg e 379,1 kg, respectivamente) ou aveia branca (449,3 kg e 378,0 kg, respectivamente) em relação aos animais que receberam arroz (401,9 kg e 341,0 kg, respectivamente). A exceção da gordura de coração e da gordura abomasal, para os demais depósitos de tecido adiposo, os animais alimentados com arroz apresentaram menores valores. Os novilhos apresentaram maior desenvolvimento dos órgãos internos (3,67% contra 3,24%), das patas (2,33% contra 2,06%) e total de componentes periféricos (15,9% contra 15,1%), enquanto as novilhas apresentaram maior deposição no total de gorduras (6,45% contra 5,75%), expressos em relação ao peso de corpo vazio. A utilização de dietas de alto grão a base de milho ou aveia branca na terminação de bovinos acarreta maior desenvolvimento de órgãos internos e do trato digestório, enquanto a alimentaçãocom grãos de arroz proporciona menor deposição de tecido adiposo.EDUFU2018-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3720210.14393/BJ-v34n3a2018-37202Bioscience Journal ; Vol. 34 No. 3 (2018): May/June; 709-718Bioscience Journal ; v. 34 n. 3 (2018): MAI/JUNE; 709-7181981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/37202/22234Brazil; ContemporaryCopyright (c) 2018 Jonatas Cattelam, Flânia Mônego Argenta, Dari Celestino Alves Filho, Ivan Luiz Brondani, Diego Soares Machado, Lucas Braido Pereira, Gilmar dos Santos Cardoso, Marcelo Ascoli da Silva, Sander Martinho Adams, Alexandra Fabielle Pereira Viana, Mauren Burin da Silva, Camille Carijo Domingueshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCattelam, JonatasArgenta, Flânia MônegoAlves Filho, Dari CelestinoBrondani, Ivan LuizMachado, Diego SoaresPereira, Lucas BraidoCardoso, Gilmar dos SantosSilva, Marcelo Ascoli daAdams, Sander MartinhoViana, Alexandra Fabielle PereiraSilva, Mauren Burin daDomingues, Camille Carijo2022-02-15T01:21:56Zoai:ojs.www.seer.ufu.br:article/37202Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-15T01:21:56Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
