Resumo: An experiment using 216 finishing Landrace x Large White barrows and crossbred gilts was conducted to determinate the effects of three quantities of rations: high level (9.28 Mcal DE/day), medium level (8.53 Mcal DE/day) and low level (8.16 Mcal DE/day), and two crude protein levels (16% and 13% PB). During the growing period all pigs received the same diet (16% PB, 3.35 Mcal DE/kg) ad libitum. During the finishing period starting at 59.76 ± 0.29 kg a randomized block design was utilized. Average daily gain (ADG decreased from medium to low scale (P<0.05), and no difference was observed from high to medium scale (P>0.05). The 16% PB level was better than 13% PB for ADG. An interaction (P<0.05) between scales and protein levels on feed gain ratio was observed. No significant effects (P>0.05) were observed on the carcass trait but protein levels promoted significant differences (P<0.05). Gilts had longer carcasses, less back fat and larger loin eye area than barrows. It was concluded that the best performance was achieved when pigs received the medium scale with 16% PB.

Na fase de crescimento, os suínos receberam a mesma dieta à vontade e, na terminação, que iniciou aos 59,76 ± 0,29 kg, foram implantados os tratamentos em delineamento experimental com seis blocos casualizados. O ganho de peso diário médio (GPDM), na quantidade baixa, foi inferior (P<0,05), não havendo diferença entre a alta e a média (P>0,05). O nível de 16% de PB, comparado com 13% de PB, melhorou o GPDM. Houve interação significativa (P<0,05) das quantidades de ração com os níveis de PB na variável conversão alimentar (CA). As quantidades de ração não ocasionaram efeitos significativos (P>0,05); porém, os níveis protéicos proporcionaram diferenças significativas. (P<0,05) sobre as mesmas. As fêmeas apresentaram carcaças com menos gordura e maior comprimento de carcaça (CC) e área de olho de lombo (AOL) do que os machos castrados (P<0,05). Concluiu-se que o melhor desempenho foi conseguido quando os animais receberam a quantidade de alimentação média com 16% de PB.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBellaver, ClaudioBarbosa, Hacy P.Partridge, Ian G.Guidoni, Antônio L.Blume, Elena2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14221Pesquisa Agropecuaria Brasileira; v.22, n.1, jan. 1987; 99-104Pesquisa Agropecuária Brasileira; v.22, n.1, jan. 1987; 99-1041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14221/8161info:eu-repo/semantics/openAccess2014-09-26T14:26:33Zoai:ojs.seer.sct.embrapa.br:article/14221Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T14:26:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
