Impact of Dietary Fatty Acids on Oocyte Quality and Development in Lactating Dairy Cows1
Abstract The purpose of this study was to examine the effects of level of rumen inert fatty acids on developmental competence of oocytes in lactating dairy cows. Estrous cycles were synchronized inExpand

Effect of dietary-induced changes in plasma insulin concentrations during the early post partum period on pregnancy rate in dairy cows.
Dietary stimulation of insulin in post partum dairy cows has been found to enhance ovarian follicle development but to impair oocyte developmental competence. The objective of this study was to testExpand

The Effect of Linolenic Acid on Bovine Oocyte Maturation and Development1
Dietary polyunsaturated fatty acids can influence reproductive performance. In dairy cattle, some high-fat diets resulted in higher blastocyst rates and improved embryo quality. These effects mayExpand

Characterization of the uterine phenotype during the peri-implantation period for LIF-null, MF1 strain mice.
Leukemia inhibitory factor plays a major role in the uterus and in its absence embryos fail to implant. Our knowledge of the targets for LIF and the consequences of its absence is still veryExpand

Impact of linoleic acid on bovine oocyte maturation and embryo development.
Linoleic acid (LA; 18:2 n-6) is the most abundant fatty acid in bovine follicular fluid, and it was previously reported that LA concentration significantly decreases when follicle size increases.Expand

Oocyte quality in lactating dairy cows fed on high levels of n-3 and n-6 fatty acids.
Different fatty acid (FA) sources are known to influence reproductive hormones in cattle, yet there is little information on how dietary FAs affect oocyte quality. Effects of three dietary sources ofExpand

Effect of α-linolenic acid on oocyte maturation and embryo development of prepubertal sheep oocytes.
The purpose of this study was to evaluate the effect of omega-3 α-linolenic acid (ALA) added to the IVM medium on embryo development of prepubertal sheep oocytes. Experiment 1 investigated the effectExpand

Influence of caffeine pretreatment on biphasic in vitro maturation of dog oocytes.
Phosphodiesterase (PDE) inhibitors have been utilized for in vitro maturation (IVM) of oocytes to manipulate the meiotic resumption and progression. Premature chromatin condensation and DNAExpand

Role of hyaluronic acid in maturation and further early embryo development of bovine oocytes.
Hyaluronic acid (HA), an important component of the extracellular matrix, plays a crucial role for cumulus cell expansion. Genes and proteins involved in HA synthesis and its receptor CD44 areExpand
