“…Imbricate cuticle scale patterns were detected in large ruminants, goat, and horse hairs. This type is also observed in the same animals (except large ruminant) but of the scalp's hair (Cortellini et al, 2019).…”

“…Furthermore, the morphology of hairs can be used to identify the human gender, age, and hair pigmentation (Ali et al, 2015). Kshirsagar et al (2009) and Cortellini et al (2019) documented the comparison between human and animal hairs. This comparison is helpful to recognize physical contact with a suspect and crime scene.…”

“…Trivedi (2015) also detected this type in cow. Moreover,Cortellini et al (2019) described that the hair scale shape tends to be elongated, pointed, and hexagonal in cow, domestic cat, and rabbit, respectively. In donkey, the scale pattern was coronal (crown), crenate with close distance margin.Ahmed et al (2018) reported similar T A B L E 2 findings…”

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.

“…Tridico (2005) applied the comparative microscopic examination of animals hair in forensic science. Moreover, hair morphology is used as a tool for recognition of buffalo, camel, cow, horse, donkey, sheep, goat, dog, and cat (Ahmed, Ali, & Ghallab, 2018), identification of the wild animal species (Bhat, Shrivastav, Dar, & Bari, 2014), and differentiate human hair from animal hair (Cortellini, Carobbio, Brescia, Cerri, & Verzeletti, 2019; Kshirsagar, Singh, & Fulari, 2009). Furthermore, Meyer and Neurand (1987), and Meyer, Schwarz, and Neurand (1978) efficiently demonstrated species‐specific differences in the skin of domestic mammals.…”

The current study aims to provide a new method for the identification of animal species by using the scanning electron microscopic study on the nasal skin around the nostril. The reference databases for animal identification using traditional ways (i.e., hair and bone analyses) were somewhat available. This study was conducted on the nasal skin of seven different animal species: large ruminants (Saidi buffalo and frozen Angus cattle); small ruminants (Egyptian goat and Rahmani sheep); camels (one‐hump dromedary camel); equines (African domestic donkey and Arabian horse); carnivores (farm domestic cat, Egyptian Baladi dog, and red fox); swine (Danish Landrace pig); and rodents (albino rat and New Zealand white rabbit). The nasal skin was divided by grooves into different shaped raised areas in some examined animals, the mean diameter of these areas and width of the grooves of each animal species were recorded. The characteristic differential features of the nasal skin of each animal species have been documented. Few openings of the nasolabial glands were demonstrated in large ruminants and swine, which were H letter‐shaped in buffaloes, oval‐shaped in cattle, and whirlpool‐shaped with several layers of folds on their margin in pig. Moreover, the openings of the lateral nasal glands were whirlpool, ovoid, and oval shaped in goats, sheep, and camels, respectively. In conclusion, the present study proved that the skin around the nostrils plays an important role as means of identification in forensic investigations and improves the field of veterinary forensic medicine in general, which is not well‐developed in comparison with human forensics.

“…Species identification can be successfully established through the use of many of these approaches using incomplete bone samples. More specifically, molecular identification (Holland and Parsons, 1999;Moore and Frazier, 2019;Pereira et al, 2019), macroscopic identification (Corrieri and Márquez-Grant, 2019), microscopic identification (Nganvongpanit et al, 2015;Cummaudo et al, 2018;Cortellini et al, 2019;Cummaudo et al, 2019) and/or elemental composition (Nganvongpanit et al, 2016c;Nganvongpanit et al, 2017b) can all be achieved with incomplete specimens. However, each approach is associated with its own set of advantages and disadvantages.…”

One major question that arises when we talk about the elements in bones is whether all bones contain the same elements. This study was implemented to answer this question and determine what the elemental levels are in the femur bones of pigs using the handheld X-ray fluorescence technique. Ten dry femur bones taken from adult domestic pigs (Sus scrofa domesticus) were scanned using a handheld XRF analyzer. We compared three different groups in this study. First, comparisons were made between six locations of the whole femur bones as follows; compact bone at diaphysis (CD), compact bone at epiphysis (CE), spongy bone at diaphysis (SD), spongy bone at femoral head (SFH), spongy bone at femoral trochlea (SFT) and spongy bone at metaphysis (SM). Second, the different parts of the compact bones at the diaphysis were compared (proximal, middle and distal), Third, comparisons were made among four directions at the diaphysis (cranial, caudal, lateral and median). Differences in the elemental percentages and Ca/P ratio among all locations were determined by one-way ANOVA. The presence of most of the detected
