The objective was to investigate the context, approach and research topics present in the papers that analysed trace elements in beef cattle to identify gaps and scientific perspectives for the sustainable management of trace elements in livestock. The main research groups came from the United States, Spain, Japan, Brazil, India and Slovakia, which represented 31% of the papers produced. Only 37% of studies addressed aspects that integrated animal, environmental and human health. The reviewed papers concerned 56 elements and 15 bovine tissues (Cu, Zn, Pb, liver, muscle and kidney highlighted). The main gaps were (1) lack of research in developing countries, (2) the need to understand the impact of different environmental issues and their relationship to the conditions in which animals are raised, and (3) the need to understand the role of many trace elements in animal nutrition and their relationship to environmental and human health. Finally, we highlight possible ways to expand knowledge and provide innovations for broad emerging issues, primarily through expanding collaborative research networks. In this context, we suggest the adoption of the One Health approach for planning further research on trace elements in livestock. Moreover, the One Health approach should also be considered for managers and politicians for a sustainable environmental care and food safety.

“…Mineral levels in hair are not related to dietary intake (Puls, 1994). Nevertheless, Szigeti et al (2015) proved that breed differences exist in some elements of hair mineral content even in the case of similar nutrition.…”

“…In the current study, microscopic comparison analysis of domestic animal hair, such as large ruminants (buffalo and cattle), small ruminants (goat and sheep), equines (donkey and horse), and carnivores (cat and dog), was performed to evaluate and identify the characteristics found in hair. With regard hair cuticle scale pattern, morphometric analysis of hair layers, and hair elemental analysis were documented, using several previously published data as a guide (Ahmed et al, 2018; Deedrick & Koch, 2004a; Gabryszuk et al, 2010; Karczmarczyk & Gryzińska, 2019; Kshirsagar et al, 2009; Szigeti et al, 2015).…”

Performance scanning electron microscopic investigations and elemental analysis of hair of the different animal species for forensic identification

Veterinary forensics have attracted less attention compared with human forensics. Animal hair morphological examination using scanning electron microscopy (SEM) and hair mineral analysis using energy-dispersive X-ray fluorescence (ED-XRF) provide reference databases for animal hair identification used in forensic investigations. This study was performed on four different animal species: large ruminants (buffalo and cattle), small ruminants (goat and sheep), carnivores (cat and dog), and equines (donkey and horse). The hair scale pattern, scale margin type, and distance between scales were identified. The hair scale pattern was imbricate in large ruminants, goat, and horse; coronal (crown-like) in carnivores and donkey; and spinous in sheep. The morphometric measurements, including cuticle layer thickness, cuticle scale height, cortex diameter, and hair shaft width were recorded. The highest cuticle thickness was found in horse, and the highest cuticle hair scale was detected in cattle. Moreover, the largest cortex diameter was measured in buffalo, whereas the smallest one was in cat. With regard the content of hair elements, some elements were specific for the hair of certain tested animals, such as bromine in sheep and magnesium and phosphorus in buffalo. In addition, vanadium and titanium were found only in cattle and dog, and the latter element was also detected in sheep. In conclusion, this study provides two techniques for animal hair identification that can be used in forensic investigations. Research highlights• Hair scale pattern was imbricate in (large ruminants, goat, and horse); coronal in (carnivores and donkey); and spinous in (sheep) with different scale margins type.• Hair shaft width in all tested animal species ranged from 23.78 ± 1.24 μm to 85.51 ± 1.14 μm.

“…O mecanismo comumente utilizado para a monitoração do status mineral dos animais é o exame de sangue, porém, esse método reflete apenas as condições do organismo animal no momento da coleta. Baseado em estudos realizados com humanos e outras espécies de animais (MC DOWELL et al, 1982;ARMELIN et al, 1998;PATRA et al, 2006;BODE et al, 2008;BATISTA et al, 2009;GUO et al, 2010;ROUG et al, 2015a;SZIGETI et al, 2015;HOLASOVÁ;PECHOVÁ;HUSAKOVÁ, 2017;TREU et al, 2018;SACH et al, 2020;RUDNICKI-VELASQUEZ et al, 2021), a utilização dos pelos como matriz analítica pode ser um método alternativo para a avaliação do conteúdo mineral no organismo de bovinos. Os pelos possuem grande valor biológico devido ao potencial de acumular informações ao longo do tempo.…”

“…Os valores encontrados por esses autores para Se (0,47 ± 0,58 mg kg -1 ) e Zn (135 ± 8 mg kg -1 ) estão próximos aos valores encontrados neste trabalho. Szigeti et al (2015) reportaram valores entre 7,02 e 9,20 mg kg -1 para Se e 80 e 84 mg kg -1 para Zn em amostras de pelo bovino. Essas faixas de frações de massa não corroboram os valores aqui apresentados.…”
