Resumo: Performance data of 120 Landrace boars tested in the Concórdia (SC) central test Stations were analyzed in 1976. The animals were tested under two feeding systems: "ad-libitum" and "controlled". Equal number of observations was available in both systems. The aim was to verify the performance differences between groups and probable influences on a breeding program. Phenotypic correlations between characteristics were estimated and data were compared in the growing (30 to 60 kg), finishing (60 to 100 kg) and whole (30 to 100 kg) periods. Animals tested under controlled feeding system (two times a day, according to the live weight) presented better performance, specially on feed efficiency. It was also observed that the feeding table, based on live weight, did not supply the requirements of the animals, whose performance was worse than that of the animals in "ad-libitum" system, during the growing period. Such a fact did not occur in the finishing period. Since the test results will be applied in she farms, where usually "ad-libitum" feed is used, none advantage was observed in the controlled feed. Moreover, controlled feeding system is more expensive than "ad-libitum" because more work is needed to conduct the test. It was observed however a greater correlation between feed efficiency and daily gain in the controlled feeding system.

Os animais foram testados com alimentação “controlada" e “à vontade", em igual número de observações para ambos os Sistemas. O objetivo do trabalho foi verificar as diferenças entre o desempenho dos dois grupos e suas possíveis influências num programa de melhoramento genético. Foram estimadas correlações fenotípicas entre as características, e os dados foram comparados na fase de crescimento (30 a 60 kg), terminação (60 a 100 kg) e no período total (30 a 100 kg) de peso vivo. Em termos de desempenho, os animais testados sob alimentação controlada (duas vezes ao dia, conforme o peso vivo) apresentaram vantagens, principalmente quanto à conversão alimentar. Observou-se, ainda, que a tabela de alimentação, em função do peso vivo do animal, resultou em restrição alimentar durante a fase de crescimento dos animais, os quais apresentaram ganho diário de peso inferior aos dos animais com consumo "à vontade". Tal fato não ocorreu no período de terminação. Desde que não se verificou vantagem do sistema controlado, com vistas a um programa de melhoramento, sugeriu-se o uso do sistema "à vontade" por sua maior facilidade e economicidade de manejo e por representar o manejo alimentar utilizado para suínos em crescimento e terminação nos rebanhos comerciais e de reprodutores.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLudwig, ArtêmioBarbosa, Hacy PintoDonzele, Juarez LopesGomes, Paulo César2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17151Pesquisa Agropecuaria Brasileira; v.16, n.6, jun. 1981; 919-928Pesquisa Agropecuária Brasileira; v.16, n.6, jun. 1981; 919-9281678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17151/11483info:eu-repo/semantics/openAccess2014-04-15T19:45:01Zoai:ojs.seer.sct.embrapa.br:article/17151Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:45:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
