Resumo: Body weight (BW), feed intake (FI), feed efficiency (FE = FI/BW gain) and fat deposition (FD) were evaluated in broilers receiving five energy levels (3,200; 3,100; 3,000; 2,900 and 2,800 kcal metabolism energy/kg of feed) and 23% CP from 0-28 days and 19% CP from 29-49 days of age in the diet. Bird were submitted to four feeding interval of 30 minutes each (1:30, 3:00 and 4:30 hours between meals) and to a control treatment with ad libitum feeding. Statistically significant effects (P<0.05) were observed for energy levei and feeding interval. The interaction energy leveIs x feeding interval was statistically significant (P<0.05) for F1 and FE from to O to 28 days of age and for FI from O to 49 days of age. As feeding interval increased, FI and BW decreased and FE improved. Birds fed ad libitum presented the heaviest BW, FD and carcass weight

Birds fed ad libitum presented the heaviest BW, FD and carcass weightFoi realizado um experimento com o objetivo de verificar os efeitos de diferentes níveis de energia em quatro programas de alimentação bem como o desempenho e as características de carcaça de frangos de corte. Foram utilizadas rações com cinco níveis de energia (3.200, 3.100, 3.000, 2.900 e 2.800 kcal energia metabolizável/kg) com 23% de proteína bruta na fase 1-28 dias e mesmos níveis de energia; com 19% de proteína bruta na fase 29-49 dias e 20 minutos de alimentação a cada 1:30, 3:00,4:30 horas de intervalo e uma testemunha "a vontade". De modo geral, à medida que se aumentou o intervalo de alimentação, as médias de consumo alimentar, peso ao abate, peso da carcaça, percentagem de gordura, rendimento de carcaça e o ganho de peso diminuíram, mas melhorou a conversão alimentar média, independentemente do nível de energiaPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPieniz, Luiz CarlosGuidoni, Antonio LourençoGirotto, Ademir FranciscoCézar, José Samuel2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13646Pesquisa Agropecuaria Brasileira; v.25, n.10, out. 1990; 1383-1389Pesquisa Agropecuária Brasileira; v.25, n.10, out. 1990; 1383-13891678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13646/7742info:eu-repo/semantics/openAccess2014-04-17T14:26:46Zoai:ojs.seer.sct.embrapa.br:article/13646Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:26:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
