Resumo: Our aim was to determine whether microalgae (Schizochytrium limacinum) supplementation affects daily production, composition and fatty acid profile of organic milk. Eight lactating cows were kept in pasture and divided in two groups: those fed corn cob as a supplement twice a day during milking (CTL) and those fed corn cob mixed with 100 g of microalgae (ALG) per cow daily. Microalgae did not affected daily milk production and composition, but a tendency of milk fat reduction was observed. The level of stearic acid in the milk of cows fed ALG was significantly lowered 2.46-fold, whereas levels of elaidic acid and conjugated linoleic acid were significantly elevated by 3.3-fold and 1.8-fold, respectively. A significantly greater PUFA:MUFA ratio was observed in ALG treatment, while the MUFA:saturated fatty acid ratio showed a tendency to increase (P=0.073). Microalgae rich in omega-3 fatty acids successfully enrich organic milk without negatively affecting productivity or composition. Consumers could be attract to increase the intake of omega 3 polynsaturated fat from organic milk. These results could support nutritionist and farmers decision to feed microalgae to dairy cattle since it is economically viable.

Ocho vacas lactantes se mantuvieron en pastoreo y se dividieron en dos grupos: las alimentadas con mazorca de maíz como suplemento dos veces al día durante el ordeño (CTL) y las alimentadas con mazorca de maíz mezclada con 100 g de microalgas (ALG) por vaca al día. Las microalgas no afectaron la producción y composición diaria de la leche, pero se observó una tendencia a la reducción de la grasa de la leche. El nivel de ácido esteárico en la leche de las vacas alimentadas con ALG se redujo significativamente 2,46 veces, mientras que los niveles de ácido elaídico y ácido linoleico conjugado se elevaron significativamente 3,3 y 1,8 veces, respectivamente. Se observó una relación PUFA: MUFA significativamente mayor en el tratamiento con ALG, mientras que la relación MUFA: ácidos grasos saturados mostró una tendencia a aumentar (P = 0,073). Las microalgas ricas en ácidos grasos omega-3 enriquecen con éxito la leche orgánica sin afectar negativamente la productividad o composición. Los consumidores podrían verse atraídos por aumentar la ingesta de grasas polinsaturadas omega 3 de la leche orgánica. Estos resultados podrían respaldar la decisión de nutricionistas y agricultores de alimentar con microalgas al ganado lechero, ya que es económicamente viable.Nosso objetivo foi determinar se a suplementação de microalgas (Schizochytrium limacinum) afeta a produção diária, composição e perfil de ácidos graxos do leite orgânico. Oito vacas em lactação foram mantidas a pasto e divididas em dois grupos: as alimentadas com sabugo de milho como suplemento duas vezes ao dia durante a ordenha (CTL) e as alimentadas com sabugo de milho misturado com 100 g de microalgas (ALG) por vaca diariamente. As microalgas não afetaram a produção e composição diária do leite, mas foi observada uma tendência de redução da gordura do leite. O nível de ácido esteárico no leite de vacas alimentadas com ALG foi significativamente reduzido em 2,46 vezes, enquanto os níveis de ácido elaídico e ácido linoléico conjugado foram significativamente elevados em 3,3 vezes e 1,8 vezes, respectivamente. Uma proporção significativamente maior de PUFA: MUFA foi observada no tratamento com ALG, enquanto a proporção de MUFA: ácido graxo saturado mostrou uma tendência a aumentar (P = 0,073). Microalgas ricas em ácidos graxos ômega-3 enriquecem com sucesso o leite orgânico sem afetar negativamente a produtividade ou composição. Os consumidores podem ser atraídos para aumentar a ingestão de gordura polinsaturada ômega 3 do leite orgânico. Esses resultados podem apoiar a decisão de nutricionistas e agricultores de alimentar o gado leiteiro com microalgas, uma vez que é economicamente viável.Research, Society and Development2021-08-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1882110.33448/rsd-v10i10.18821Research, Society and Development; Vol. 10 No. 10; e277101018821Research, Society and Development; Vol. 10 Núm. 10; e277101018821Research, Society and Development; v. 10 n. 10; e2771010188212525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/18821/16824Copyright (c) 2021 Neiva Carneiro; Wilson Zacaron; Gabriel Rossato; Gabriela Solivo ; Renata Bolzan Falk; Roger Wagner; Aleksandro S. da Silva; Claiton André Zottihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarneiro, NeivaZacaron, WilsonRossato, GabrielSolivo , Gabriela Falk, Renata Bolzan Wagner, RogerSilva, Aleksandro S. da Zotti, Claiton André2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/18821Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:51.888905Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
