The objective of this project is to evaluate how the initial nutrition of neonates affects intestinal bacterial diversity, intestinal and general health, metabolism and performance of dairy calves. For this, three experiments will be carried out, whose focus are: 1) Assess the quality, bacterial diversity, the presence of resistant pathogens and antibiotic residue in colostrum and transit…

Experiments are being carried out to help clarify physiological aspects related to ovulation and maintenance of pregnancy in bovine females submitted to artificial insemination (AI) or embryo transfer (ET). In addition, studies are evaluating strategies to increase the efficiency and/or simplify the use of timed artificial insemination (TAI) or embryo production protocols. The project pro…
The animal category of heifers presents the greatest genetic potential within bovine herds. Recently, interest in reducing the age to puberty and first calving has been awakened, in order to increase the productive life of females on farms and increase the economic benefits to production systems. The Nelore breed makes up most of the national beef cattle herd, and the use of younger heife…
The present project proposes the conduction of five experiments aiming to understand how the circulating concentrations of estradiol (E2) and progesterone (P4), modulated exogenously or endogenously, affect the responsiveness of the pituitary and the release of LH and FSH, as well as understanding what is the influence of GnRH pulsatility in the regulatory pathways exerted by these steroi…

The present project aims to evaluate the effect of circulating concentrations of estradiol (E2) and progesterone (P4), modulated exogenously, on the responsiveness of the pituitary and release of gonadotropins, as well as understanding the influence of GnRH pulse frequency in the regulatory pathways exerted by these steroids in heifers from distinct genotypic groups (Bos taurus vs. Bos in…
Follicular growth during bovine estrous cycle occurs in the form of waves and consists of the following phases: 1) emergence of the follicular wave (FW), in which the follicles present 4 mm in diameter; 2) follicular deviation (FD), that occurs when follicles are measuring around 8.5 mm diameter in Bos taurus and 6 to 7 mm in Bos indicus and 3) ovulation, in which the developing dominant …
Radioimmunoassay (RIA) is widely used for hormone concentrations analyses and it presents high specificity and sensitivity. However, this method requires the use of radioactive labels, which can be harmful to the operators and requires adequate disposal of the reagents in order to avoid radioactive pollution. Further, the reagents employed in this method present a short shelf life and its…
