Cattle tick fever (CTF) is one of the main parasitic diseases afflicting cattle. In Brazil the most recent estimates are that this ailment causes yearly losses to breeders amounting to more than 500 million dollars, due to mortality, morbidity, reduced milk and meat production, stillbirths, reduced fertility and expenses for vaccines and treatment of sick animals. CTF is a complex formed …
The probability of pregnancy is a trait of high economic value to Nellore heifers. The variability among them is not always detected because most breeders do not expose the heifers in a young age also because this trait presents a binomial distribution (pregnancy or no pregnancy), which can difficult the analysis. The maturation of the hypothalamic-pituitary-gonadal axis on early pregnanc…
In this study, it will be evaluated the level of infection with Babesia bovis and B. bigemina in beef cattle naturally infested by the tick Rhipicephalus (Boophilus) microplus. 200 cattle will be used for a race taurine and 200 crossbred Zebu-taurine. Will have all ticks present on the right side of the body counted. It will be performed three counts of ticks at intervals of 15-20 days, t…

Practices that result in improved reproductive and growth efficiencies have been recognized as an important factor affecting the economic sustainability of beef cattle herds by reducing production costs and generation intervals. However, in the tropical beef cattle production systems, Nellore heifers are raised mainly on pasture under a wide range of topographic and climatic regions with …
The adaptation process to tropical environment conditions and selection history in Brazilian Nelore herd make this breed an interesting instrument of study to detect signals of selection. The aim of this study will be to use genome sequence data of Nelore cattle to investigate signatures of selection using runs of homozygosity (ROH) islands and hapFLK statistic, and to perform single-step…
The Tetragonisca angustula is a corbiculate bee, extremely social, stinglessand well distributed in Brazilian territory. This bee has an important role for the ecosystem by polinizing and for economic through the production of honey. The T. angustula bees are grouped in the tribe Meliponini and belong to family Apidae, divided in the subfamily Xylocopinae and the corbiculates bee. The cor…
In Brazil, the most recent estimates are that the cattle tick fever (CTF) causes yearly losses to breeders amounting to more than 500 million dollars, due to mortality, morbidity, reduced milk and meat production, stillbirths, reduced fertility and expenses for vaccines and treatment of sick animals. CTF is a complex formed by two ailments: babesiosis and anaplasmosis, caused by different…

Advances in next-generation sequencing techniques associated to a drastically decreasing in sequencing costs is favoring the development of strategies to explore the complete DNA sequence in genetic evaluations due to the possibility of using causal mutations. Anyway, it is still cheaper genotyping a large number of animals than sequencing them. An alternative and cost-effective strategy …
A constant challenge in tropical animal husbandry is the control of parasites, such as the tick Rhipicephalus (Boophilus) microplus and the hemoparasites transmitted by it, especially Babesia bigemina, a protozoan that causes severe losses in herds. Therefore, the objective of this proposed research will be to carry out a broad genome-wide association study (GWAS) to determine the charact…
Health professionals have recommended a reduction in overall consumption of saturated fatty acids and an increase in the intake of unsaturated fatty acids. This has motivated the development of strategies that objective to alter the beef fatty acid composition to be more compatible with the consumer requirements. Many genome-wide association studies (GWAS) have identified genetic variants…
