Resumo: The objective of this work was to identify and quantify, through multiple linear regression models, the factors of production that affect the daily feed intake and feed conversion ratio of pigs in the growing and finishing phases, in farms linked to a company. The production records of 690 batches were evaluated, representing approximately 363 thousand animals housed between 2010 and 2013 in 118 commercial farms linked to a company in the state of Paraná, Brazil. Forty‑four factors of production related to facilities, management, health status, genetics, and feeding were considered. Daily feed intake (DFI) was lower in batches from farms that had trees planted on the sides of the barns and in those formed only by females. The feed conversion ratio (FCR) was better in batches from farms with trees on the sides of the barns, housed during summer/fall, originated from farms with barns built of masonry and that had compost bins and specialized units for producing piglets. The initial and final weights of the batches affected DFI, and the initial weight and duration of the growing and finishing phases, the FCR. The multiple linear regression models allow identifying important variables and estimating their effects on FCR and DFI of pigs in the growing and finishing phases.

Foram avaliados os históricos produtivos de 690 lotes, que representavam aproximadamente 363 mil animais alojados entre 2010 e 2013 em 118 granjas vinculadas a uma cooperativa do Estado do Paraná. Foram considerados 44 fatores de produção relacionados a instalações, manejo, sanidade, genética e alimentação. O consumo diário de ração (CDR) foi menor nos lotes oriundos de granjas com árvores nas laterais dos galpões e naqueles formados apenas por fêmeas. Já a conversão alimentar (CA) foi melhor para os lotes provenientes de granjas com árvores nas laterais dos galpões, alojados no verão/outono, oriundos de granjas edificadas em alvenaria e que apresentavam composteira e unidades especializadas produtoras de leitões. Os pesos de entrada e de saída dos lotes influenciaram o CDR, e o peso de entrada e a duração do período de engorda, a CA. Os modelos de regressão linear múltipla possibilitam identificar variáveis de importância e estimar seus efeitos sobre a conversão alimentar e o consumo diário de ração de suínos nas fases de crescimento e terminação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileiradaily feed intakefeed conversion ratioequationsmultiple regressionCooperativa Agroindustrial Consolata (Copacol)Ministerio de Educación, Cultura y Deporte (AGL 2011‑29960)Silva, Caio Abércio dada Silva Agostini, PieroCallegari, Marco AurélioSantos, Rita de Kássia Silva dosNovais, Aliny KétilimPierozan, Carlos RodolfoPereira Junior, MarcinoAlves, Jefferson BastosGasa Gasó, Josep2016-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/23702Pesquisa Agropecuaria Brasileira; v.51, n.10, out. 2016; 1780-1788Pesquisa Agropecuária Brasileira; v.51, n.10, out. 2016; 1780-17881678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/23702/13610https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23702/15619Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-12-02T19:45:20Zoai:ojs.seer.sct.embrapa.br:article/23702Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-12-02T19:45:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
