A study on the detection of cattle in UAV images using deep learning. Repositório Alice
BARBEDO, J. G. A.; KOENIGKAN, L. V.; SANTOS, T. T.; SANTOS, P. M..
Abstract: Unmanned aerial vehicles (UAVs) are being increasingly viewed as valuable tools to aid the management of farms. This kind of technology can be particularly useful in the context of extensive cattle farming, as production areas tend to be expansive and animals tend to be more loosely monitored. With the advent of deep learning, and convolutional neural networks (CNNs) in particular, extracting relevant information from aerial images has become more effective. Despite the technological advancements in drone, imaging and machine learning technologies, the application of UAVs for cattle monitoring is far from being thoroughly studied, with many research gaps still remaining. In this context, the objectives of this study were threefold: (1) to...

Association of CSSM066 and ILSTS011 microsatellite markers and thyroglobulin gene SNP with backfat in Canchim cattle Scientia Agricola

Canchim, a synthetic breed of cattle derived from the Charolais and Zebu group has been used in the beef-cattle industry in Brazil as an alternative for intensifying production. One of the main concerns with this breed is its poor fat deposition and consequently, there is an effort to increase the performance for this trait. The thyroglobulin gene is located in a QTL region for fat deposition, and reports describe the influence of a polymorphism in the 5´ leader sequence of that gene on marbling and subcutaneous fat thickness. This study analyzed the association of this polymorphism in the thyroglobulin gene, as well as of two flanking microsatellite markers, CSSM066 and ILSTS011, with backfat thickness in 987 Canchim beef cattle. The CSSM066 and ILSTS011...

Genome-wide association study on long-yearling scrotal circumference in Canchim cattle. Repositório Alice
BUZANSKAS, M. E.; GROSSI, D. A.; VENTURA, R. V.; CHUD, T. C. S.; URBINATI, I.; MEIRELLES, S. L. C.; MOKRY, F. B.; SCHENKEL, F. S.; REGITANO, L. C. de A.; MUNARI, D. P..
Genome-wide association studies provide valuable information for understanding the genetic control of complex traits in livestock. The goal of this study was to investigate the association of the BovineHD BeadChip SNP genotypes with estimated breeding values for long-yearling scrotal circumference adjusted to 420 days (SC420) in Canchim beef cattle. A total 435 SNPs were significantly associated with SC420 (10% chromosome-wise FDR), of which 30 were located in genes on chromosomes 5, 13, and 14, including HEY1, PLCG1, PAG1, ZFHX4, PEX2, FABP5, FABP12, MED30, and TRHR genes. These genes play a role in biological processes related to reproduction, fat deposition, and hormonal systems development. Future studies targeting these regions and genes could provide...
