Professor of Animal Reproduction at the University of São Paulo in Brazil. He holds an undergraduate degree in Veterinary (1985) with a Master (1992) and PhD (1997) in Animal Reproduction from São Paulo University. He was president of Brazilian Embryo Transfer Society (SBTE/2012-2014) and member of Executive Committee of International Congress of Animal Reproduction (ICAR/2012-2022). Professor Barusellis research and teaching are in the areas of control of the follicular dynamics and ovulation for self-appointed artificial insemination and embryo transfer in dairy and in beef. He has over 300 scientific publications (Fator H = 44; Scopus) and over 600 abstract presented in scientific congress on a wide range of topics including physiology of reproduction, synchronization of ovulation, biotechnology of reproduction and reproductive efficiency and management. He has supervised 62 completed Master and PhD candidatures and has extensive international experience. (Source: Lattes Curriculum)

The use of young animals for reproduction is of great interest for the beef and dairy production chains, especially regarding the use of in vitro embryo production (IVEP), because it contributes to the maximization of the herd's potential, allowing the reduction of generation intervals and increase of genetic gain due to rapid dissemination of high value genetic material. Among the factor…
Holstein cows during lactation are frequently associated with reduced reproductive efficiency relative the heifers. Among the potential causes can be cited lower oocyte competence which lead to low conception rates and lower efficiency of production programs in vitro embryos (IVP). Changes in energy metabolism appear to influence oocyte competence of lactating females during lactation. Fu…
The amount of food/energy ingested by Bos taurus and Bos indicus heifers affect the characteristics of their estrous cycle, such as ovarian structure dimensions and circulating concentration of steroidal hormones. Studies have been demonstrated that the maximum size of the dominant follicle and corpus luteum is higher in taurine than in zebu females, what can suggest a higher steroidal ho…

The aim of this project is to evaluate the effects of administering 325 mg of recombinant bovine somatotropin (bST; Posilac®) on the quality and quantity of oocyte cumulus complex (COCs) recovered by follicular aspiration and on the efficiency of in vitro embryo production (IVEP) in Holstein heifers. The central hypothesis is that the treatment with bST at the beginning of follicular grow…
Early diagnosis of gestation is an important tool to increase the reproductive efficiency and profitability of dairy herds. Interferon-tau is a glycoprotein secreted by the embryo and essential for the maternal recognition of the embryo. Secretion of IFN-tau during embryo implantation stimulates the expression of genes (ISGs) in peripheral blood immune cells in blood females and can be us…
The success of embryo transfer (ET) implies knowing the factors that can influence the fertility enhancement of embryo recipients for decision making in the art technique. The present study is evaluated on the day of data transfer of the life cycle, area, volume, CL blood flow and concentration of P4 and its correlations with a rate of. In contact with the company In Vitro Brasil-IVB (loc…
Reproductive biotechniques such as AI, ET-in vivo and ET-in vitro have been applied as a management strategy aiming a greater productivity and reproductive efficiency in Brazilian and worldwide cattle breeding. However, there are differences in the reproductive efficiency of these biotechnologies that compromise the productive and reproductive performance of the herds. Thus, the objective…
