Approaches to improve survival, growth, and maturation of caprine oocytes: main results from LAMOFOPA-Brazil.

This brief review delves into the topic of follicle culture for embryo production, with a particular emphasis on goat models. Specifically, we examine the main findings from LAMOFOPA-Brazil over the last 20 years, highlighting the challenges posed by oxidative stress and epigenetic changes. Our focus is on strategies to improve follicular development and oocyte maturation.

Ultra-diluted/dynamized doxorubicin reduces the toxicity caused by doxorubicin during the in vitro culture of pig preantral follicles enclosed in ovarian tissue.

The present study investigated the effect of adding allopathic doxorubicin (DOX 0.3 µg/mL), the vehicle of ultradiluted/dynamized doxorubicin (0.2 % ethanol), different dynamizations of ultradiluted/dynamized doxorubicin (DOX 6CH, DOX 12CH and DOX 30CH), both in the absence or presence of chemical stress induced by doxorubicin at 0.

Oocyte competence and gene expression in parthenogenetic produced embryos from repeat breeder and normally fertile buffaloes (Bubalus bubalis) raised in sub-humid tropical climate.

The reproductive management of the buffalo species still faces several unresolved problems, which directly affect the productivity of the herd, one of them being the presence of repeat breeder females. Given this scenario, this study aimed to verify the developmental competence of oocytes obtained from repeat breeder females and submitted to parthenogenetic activation. In addition, embryo gene expression was compared to normally fertile females.

Factors affecting the embryo production in buffalo (): A review.

Under natural and well-managed conditions, the buffalo has good reproductive and productive indices. However, embryo production (IVEP) has been used commercially to maximise the number of elite animals. In this species, several factors (donor management, culture medium, semen, conditions, embryo transfer) still affect the IVEP results.

Evaluation of in vitro culture systems for goat preantral follicles using reused ovaries from reproductive biotechniques: An alternative to maximize the potential of reproduction.

This study aimed to examine the in vitro culture of secondary preantral follicles, using reused ovaries, to compare both the 2D and 3D methods of in vitro culture of preantral follicles, and the system of medium replacement. Twenty-five pairs of ovaries from mixed-breed goats were used for the experiment. Follicular puncture of antral follicles was performed for in vitro production.
