Antioxidants and dairy production: the example of flax

Abstract: -This manuscript reports on the main problems decreasing productivity of dairy cows (e.g. fatty liver syndrome and poor fertility) and how antioxidants could enhance it. High producing dairy cows are prone to oxidative stress, and the situation can be exacerbated under certain environmental, physiological, and dietary conditions. Antioxidants have important effects on the expression of genes involved in the antioxidant status, which may enhance animal health and reproduction. Moreover, antioxidants may contrib… Show more

“…Apesar de promissores, poucos estudos estão disponíveis sobre a expressão gênica e a suplementação de ômega 3. (PETIT, 2009). Além disso, estudos demonstraram que a metabolização dos compostos bioativos da linhaça pelos microrganismos colonizadores do rúmen é capaz de produzir compostos com efeitos ainda maiores à saúde humana (CÔRTES, et al, 2008).…”

“…All the daily operations at the DCEU were conducted under the guidance of the relevant teacher and carried out by students of the agricultural technical course. Thus, the students could learn about milk production, ranging from the choice of land (natural resources), artificial insemination, alimentary and nutritional management, and milking of cows, to consideration of the nutritional and functional properties of milk and dairy products for the consumer, according to the approach of Jenkins and McGuire (2006) and Petit (2009). Normative Instructions 51 and 62 of the Ministério da Agricultura, Pecuária e Abastecimento (Brasil 2002(Brasil , 2011 were also followed.…”

“…Linseed (Linum usitatissimum L.) is one such ingredient because it contains a high oil content (40%), comprising 55% 18:3 n3 (ω-3) (PETIT, 2010), and is also a source of dietary fiber and antioxidant compounds (PETIT, 2009). These characteristics have increased the conjugated linoleic acid (CLA) concentrations in milk from dairy cows (PETIT, 2015;FUKE;NORNBERG, 2017), which has been associated with reduced incidence of cardiovascular disease, hypercholesterolemia, and some types of cancer in humans (PETIT, 2009;FERLAY, 2015). Linseed fatty acids (FA) have also been shown to reduce enteric methane emissions from ruminants (MARTIN et al, 2016), decreasing greenhouse gas emissions by sequestering hydrogen from the rumen environment.…”
