Resumo: The objective of this work was to determine productive and fertility responses of Holstein‑Friesian heifers and cows to supplementation with extruded linseed and soybean as sources of polyunsaturated fatty acids (PUFAs). Supplementation had a positive effect on profitability, with significant increases in milk yield in supplemented cows, but not in heifers. Treatments had no effect on milk fat content, but higher milk protein contents were observed with supplementation. A higher conception rate was found for supplemented heifers, but not for cows. Fat sources containing PUFAs are recommended for dairy cattle supplementation, since they improve fertility in heifers and milk yield in cows.

A suplementação teve efeito positivo sobre a rentabilidade, com aumento significativo na produção de leite de vacas suplementadas, mas não na de novilhas. Os tratamentos não tiveram efeito sobre o conteúdo de gordura no leite, mas maiores conteúdos de proteína láctea foram observados com a suplementação. Houve maior taxa de concepção em novilhas suplementadas, mas não em vacas. Fontes de gordura contendo PUFAs são recomendadas para suplementação do gado leiteiro, uma vez que melhoram a fertilidade de novilhas e a produção de leite de vacas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGonzález, FélixMuiño, RodrigoPereira, VíctorMartínez, DiegoRodríguez, Cristina CastilloBermúdez, Joaquín HernándezCastellote, José Luis Benedito2015-04-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/19692Pesquisa Agropecuaria Brasileira; v.50, n.4, abr. 2015; 306-312Pesquisa Agropecuária Brasileira; v.50, n.4, abr. 2015; 306-3121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/19692/12913https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/19692/11959info:eu-repo/semantics/openAccess2015-05-08T18:39:35Zoai:ojs.seer.sct.embrapa.br:article/19692Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-05-08T18:39:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
