Resumo: The objective of the experiment was to evaluate byproducts yield of non-castrated Nellore males slaughtered at different weights. Forty Nellore males with average weight of 350 kg at the beginning of the feedlot were used. In a completely randomized design, the animals were divided into four groups: 0 to 2-teeth animals with carcass weight up to 238.0 kg (young and light carcasses); 2-teeth animal with carcass weights ranging from 238.1 to 258.0 kg (young and middle weight carcasses); 2-teeth animal with carcass weight over 258.0 kg (young and heavy carcasses) and animals with four or six teeth, regardless of carcass weight (adults). Animals were fed during 84 days with diet calculated to reach average weight gain of 1.2 kg/day. Hide weight was higher for young and heavy animals in relation to young and light and adult animals. Regarding the non-carcass components yield, we verified difference for liver percentage, which was higher for young and heavy animals (1.91%) in relation to young with middle weight carcasses (1.49%). Economic analysis showed that the non-carcass components of young animals with heavy carcass result in higher income (R$ 208.00), followed by young animals with middle weight carcasses (R$ 193.56), and the incomes of adult and of young and light animals, respectively, R$ 21.42 and R$ 23.42 lower than the first one. No carcass components add to industry from R$ 0.71 to R$ 0.80 per carcass kilogram.Keywords: beef cattle offal; Bos indicus; byproducts; feedlot; hide; industrial yield.

Foram utilizados 40 animais com peso corporal médio de 350 kg no inicio do confinamento. Em delineamento inteiramente casualizado, os animais foram divididos em quatro grupos: animais 0 e 2 dentes, com peso de carcaça de até 238,0 kg (jovens e carcaças leves); animais 2 dentes com peso de carcaça variando de 238,1 a 258,0 kg (jovens e carcaças médias); animais 2 dentes com peso de carcaça superior a 258,0 kg (jovens e carcaças pesadas) e animais com 4 ou 6 dentes, independente do peso de carcaça (adultos). Os animais foram confinados por 84 dias com dieta calculada para atingir ganho de peso médio de 1,2 kg/dia. O peso do couro foi maior nos animais jovens e pesados em relação aos jovens e leves e aos adultos. Foi verificada diferença no percentual de fígado, que foi maior nos animais jovens pesados (1,91%) em relação aos jovens com carcaça média (1,49%). A análise econômica mostrou que os animais jovens com carcaça pesada deixam a maior receita com componentes não carcaça (R$ 208,00), seguidos dos jovens médios (R$ 193,56), sendo a receita dos animais adultos e dos jovens e leves R$ 21,42 e R$ 23,42, respectivamente, inferior aos primeiros. Os componentes não carcaça agregam à indústria de R$ 0,71 a R$ 0,80 por quilograma de carcaça.Palavras-chave: Bos indicus; confinamento; couro; co-produtos; miúdos bovinos; rendimento industrial.  Universidade Federal de Goiás2015-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/1869410.1590/cab.v16i3.18694Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 16 No. 3 (2015); 313-323Ciência Animal Brasileira / Brazilian Animal Science; v. 16 n. 3 (2015); 313-3231809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/18694/18819https://revistas.ufg.br/vet/article/view/18694/18820Vaz, Fabiano NunesRestle, JoãoPádua, João TeodoroFonseca, Cristiane AmorimPascoal, Leonir LuizSevero, Marcelo Machadoinfo:eu-repo/semantics/openAccess2015-07-31T20:01:58Zoai:ojs.revistas.ufg.br:article/18694Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:53.628079Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
