Mammal hairs play a significant role in thermoregulation, body shape maintenance, waterproofing and protection from the variety of pollution. The scientific study of the hair is called as trichology and this field originated in the mids. In fact, identification of mammal hair was earlier performed by . There are mainly two types of mammalian hair found: Guard hairs that are usually thick and bristly and fine hairs which are curled and thin comparatively .
Hair analyses through their morphological cuticular scale and medullary features have been widely used to distinguish among mammalian species of interest largely in the different field of Science. The domesticated ungulates comprise the order Artiodactyla even-toed and family Bovidae. It was one of old but become advanced with the latest instrument and technology of this modern era. It is the best effective techniques widely used in the forensic as well as in the field of ecology. The distinctive MI for each species is very much suitable for species confirmation and useful to identify unknown hair samples as well as for the study of the feeding ecology of large carnivore animals by their scat analysis within and around the protected areas.
The scale count and scale pattern also found to be species-specific and therefore beneficial to identify the hair of unknown species with the help of all external and internal morphological features of the hair .
For almost a century, compound and comparison microscopes remained the only reliable tools for the microscopic identification of characteristics found in animal hair [ 4]. All the control guard hairs were collected separately and labeled further from the different cattle owners. After collection of hairs of each species were properly washed in running water for few times to remove dirt. Accordingly total one hundred twenty hairs of four domesticated bovine species were cleaned and degreased in acetone.
Then randomly picked up thirty hairs from each species were examined. First, each hair was embedded in Gelatin layered microscopic slide or Nail paint for scale imprinting. The microscope has inbuilt measurement software with the camera attachment namely: Axiocam Imager. First studied under 10X view, then in 40X view for detailed morphometric study. The morphological external features of the hair shaft were recorded with suitable details and measurement.
Later internal morphological features of the hair medulla were studied previously and recorded separately in the data book. On the basis of all external and internal morphological as well as quantitative features of the guard hair, each species confirmation was made. To distinguish the species, several differencing aspects of hair were to be considered to achieve the confidence limit. The mean value as well as standard deviation regarding various features of hair shaft and medulla are given in below Tables.
Table 1: Systematic position and conservation status of four domesticated cattle. Gir cow. Jafrabadi water buffalo. Gohilwadi goat. Patanvadi sheep. Table 2: Different factors of Hair of the four domesticated ungulate species of Saurashtra. Mean length of hair. Average diameter of hair shaft. Average diameter of medulla. Medullary Index. Jafrabadi buffalo. Different Medullary Index MI of the four domesticated ungulate species along with the standard error given Fig. Various morphological and quantitative features of the guard Hair of four domesticated species of family Bovidae studied in detail.
The mean value, as well as standard deviation regarding various features of hair shaft and medulla are given in Table 3 Fig. Table 3: Morphological features of Hair of the four domesticate Bovine species. Medulla pattern. Scale pattern. Color of hair. Hair surface. Simple medulla Amorphous. Narrow medulla. Wide medulla. Regular wave. Systematic position and conservation status - All the four domesticated species belonging to the single order Artiodactyla and similar family Bovidae.
All four domesticated cattle species acquire different genus and species. Further randomly picked thirty dorsal guard hairs of each species thoroughly evaluated under the microscope Table 1. Mean value of MI, Shaft, Medulla and whole hair- The medullary index is the specialized feature of the hair. Every species of the mammals can be identified on the basis of their medullary features Table 2, Fig. Maximum MI found in Patanvadi Sheep 0. MI is the specialized feature of the guard hair. Each and every species of the mammals can be identified on the basis of their medullary index Table 2, Fig.
Morphological features of the hair- There are a number of important morphological features to be considered for the identification and confirmation of the hair for an unknown species. The Gir cow and Jafrabadi Buffalo have simple type of medulla whereas Gohilwadi Goat has narrow medulla and Patanvadi Sheep has wide medulla comparatively Table 3, Fig.
The scale pattern of the Gir Cow and Gohilwadi Goat found to be similar but Patanvadi Sheep has regular wave pattern instead. The Jafrabadi buffalo has unique streaked scale pattern which is completely distinguishing it from other three domesticated species . Mostly from the above four bovids, Jafrabadi Water buffalo has streaked scale pattern with Simple and wide medulla, while Gir Cow and Gohilwadi Goat shows similar Regular and irregular wave pattern.
In Patanvadi Sheep has regular wave pattern of the scale with wide medulla. On another hand the quantitative features of the guard hair of animal species are distinctive and species-specific. On the basis of medulla type, only water buffalo shows distinctive scale type out of four species of domesticated bovine. The quantitative features of the guard hair of animal species are distinctive and species-specific. These differential features of the hair are largely suitable and authenticated, hence broadly used in the various field namely: ecology, field of forensic science, field of wildlife and Ethology for the hair identification of species of interest.
By using this hair identification key it can be easier and suitable to identify and confirm the species largely to know feeding ecology of carnivore animals in both protected and non-protected areas. It can be easily applicable for hair identification in case of human-carnivore conflict study. Singh, Chief Conservator of Forest, Junagadh for his encouragement and supports for the study.
