Evaluation of recovery, quality and in vitro nuclear maturation of oocytes obtained from buffalo and bovine ovaries
(2010)
Ovaries of 86 buffaloes and 95 cows were collected from slaughterhouses and transported to the laboratory in saline solution at 36o C. The Cumulus-oocyte complexes (COCs) were recovered by follicular aspiration and only ...

Effect of nutritional immunomodulation and heat stress during the dry period on subsequent performance of cows
(Elsevier B.V., 2017-08-01)
Heat stress in dairy cows during the dry period impairs milk yield in the next lactation. Feeding Omni-Gen-AF (OG; Phibro Animal Health Corp., Teaneck, NJ) to lactating cows during heat stress may increase dry matter intake ...
Extracellular vesicles of follicular fluid from heat-stressed cows modify the gene expression of in vitro-matured oocytes
(Elsevier B.V., 2019-06-01)
The effect of heat stress (HS) on cattle reproduction is deleterious with respect to ovarian follicular development and oocyte quality. The objective of this study was to investigate the effect of follicular fluid extracellular ...
