The prostaglandin E2 (PGE2) synthesized by maternal endometrium, embryo and trophoblastic cells (TC) has luteotrophic and anti-luteolytic effects favoring maternal fetal recognition. The synthesis of prostaglandin F2a (PGF2a) and PGE2 in endometrial tissue and endometrial cells has been extensively studied, however, such synthesis in TC and embryos was poorly pursued and understood. The u…
In bovine herds the early embryonic mortality, caused by failures in maternal fetal recognition between days 15 and 19 after fertilization, is one of the major causes of reproductive failures. Strategies that may favor maternal fetal recognition during such a critical period become of fundamental economic interest. Such strategies aim to reduce the ability of PGF2 alpha synthesis by the m…
The supplementation with polyunsaturated fatty acids (PUFA), among these compounds rich in linoleic acid (LA), favors the reproductive performance in bovine females. However, the determining mechanisms of this effect are little known. Among the sources of LA include the sunflower seed (Helianthus annuus L.). In previous studies by this group, it was found that supplementation with sunflow…

The manipulation of oocytes and embryos during in vitro embryo production (IVEP), as well as the culture conditions themselves, are well known to contribute to oxidative stress (OS). OS is characterized by an imbalance between the production of reactive oxygen species (ROS) and their removal through enzymatic or non-enzymatic systems. ROS induce cellular damage and trigger apoptotic mecha…
Early embryonic mortality, caused between the 14th and 19th days after fertilization, determines 20to 40% losses in female beef cattle. The reduction of such mortality, by favoring thematernal-fetal recognition, becomes of fundamental economic interest in breeding operations.Strategies for this aim to reduce the ability to synthesize PGF2± by the maternal endometrium and/ormaximize the an…
Considering that in the in vitro embryo production (IVEP) approximately 40.8% of the oocytes matured in vitro reach embryos and that of these 33% result in pregnancy after FTET, the need to improve the technique becomes evident. The present study proposes the use of a new three-dimensional (3D) culture system, specifically using the CellFate® membrane (Biocelltis, Florianópolis, Brazil) i…

The calcium status is important to activate immunological cells (Lewis, 2001) therefore it affects the risk of uterine diseases in dairy cows (Martinez, 2012) and these diseases delay post-partum ovulation, decrease pregnancy rates by artificial insemination (AI) and increase pregnancy loss. Manipulating the mineral composition of the prepartum ration by incorporating acidogenic salts to …
