The antlers can be fairly fragile and become increasingly corrugated over time. Like other deer species, only the male has the antlers. This observation is also supported by Sankar and Acharya [24] who recorded spotted deer (Axis axis) in southern Indian region is not seasonal in their antler cycle. However, there are occasions when a stag may cast early and also stags that may skip casting an entire year or more. While we did not expect age-related changes to be the same, we expected a clear variation in which male calves will show lower testosterone metabolite concentrations than the adult bucks [21]. The sambar in the hard antler stage showed a higher mean concentration of testosterone in relation to the antler cycle’s velvet stage, while such differences in testosterone levels are in agreement with the results of many other investigators. Antlers are extensions of an animal's skull found in members of the deer family. Rusa Deer (Rusa timorensis) Rusa is the Malay word for deer and they are medium sized, rough-coated deer which are biologically allied to the sambar. Ten such fecal samples belonging to each antler stage were collected, which took eighteen consecutive months to complete the expected number of samples. Although it is usually of a uniform colour, some subspecies have been noted to have chestnut marks on their rumps and underparts. See more ideas about sambar deer, deer, animals. In white-tailed deer (Odocoileus virginianus), the testosterone exhibits the highest concentration during the mating season [34], while in red deer (Cervus elaphus), the highest testosterone concentration was recorded mainly during the rutting, at the beginning of the mating season [35]. The methanol samples were placed at -20°C until the RIA assessment using the 125I testosterone RIA kit [13], and the concentration of testosterone was associated with the stages of the antler cycle. Full grown males can be about 1,200 pounds with the females weighing in at about 220 pounds. Testosterone levels peak immediately before rut, and it is the rapid decline in its level that causes antler casting. A calibre and cartridge with high striking energy is recommended as sambar deer have been known to absorb several shots and still escape. Tubes were then boiled in a water bath (90°C) for 20 minutes, adding ethanol to prevent dry cooking [22]. The Indian Sambar deer’s antlers have 6 tines, and are strongly pearled. Sambar deer were introduced to Australia around the 1860's and are native to countries such as Sri Lanka and India. However, in sambar deer of the HPNP, it was observed that most of the stags lost both their antlers on the same day, while some individuals were observed to cast their two antlers with a gap of 2-3 days . The reasons for these malformed antlers are numerous and cannot be determined in the field. Antlers are growing from the skull, only in male deer, with a solid calcified core and are unique in that they go through an annual cycle of rapid growth in preparation for the rutting season, after which they are casted [3]. The extract was preboiled with 90% ethanol and centrifuged for 20 minutes at 1500 rpm. India banned, or at least greatly restricted, the export of stag many years ago. Sambar deer shed their antlers each year. Although it primarily refers to R. unicolor, the name "sambar" is also sometimes used to refer to the Philippine deer(called the "Philippine sambar") and the Javan rusa(called the "Sunda sambar"). A point must be at least 1-inch long to be considered a true point. Japan is the only country in eastern Asia where sika deer were not farmed for velvet antlers. Old sambars turn very dark brown, almost the color black. at the shoulder. Velvet shedding and antler hardening are the consequences of high testosterone levels [39]. Rusa Deer. I personally will hunt sambar with my .30-06 while a friend of mine uses his .308. Sambar stag much more dense and solid all the way through while U.S. and European deer antlers have a much softer inner core. Findings on red deer stags revealed that mean serum testosterone concentrations increased during the breeding season up to about one to two weeks prior to the peak of the rut [36]. A large mass of feces was thoroughly mixed, and we weighed 10 aliquots of 0.5 ml wet feces. Sambar Deer (Cervus unicolor) are a widely spread species of deer native to India, but range to Nepal and the east across Southeast Asia. The largest males weigh up to 1,200 lbs., but their weight is usually between 220 – 770 lbs. The casting stage corresponded with the lowest mean testosterone concentration. HORTON PLAINS, Sri Lanka — Studying animals in their wild habitat can get quite intrusive. The sambar population found in Horton Plains National Park in Sri Lanka’s central highlands are unique. 1 x Sambar Deer shoulder mount - 27” length - $850, Good Size Boar Tusks on shield - $100, Deer Skins, average price - $70 each, 1 x large set of New Caledonian Rusa Deer Antlers mounted on wooden shield – length- 32 ¼”- Douglas Score- 196 5/8- $300, 2 x sets of Feral Goat horns, approx. The HPNP was chosen for this study because of the large number of sambar deer inhabiting the park’s wet patana grasslands. The study was carried out in Horton Plains National Park (HPNP), Sri Lanka, for a period of eighteen months (January 2018-June 2019). Antlers are grown from January to March, hardening between June and November and cast in November/December. This subspecies is one of the largest sambar deer species with the largest antlers both in size and in body proportions. A. Estevez, F. Ceacero, L. Gallego, and A. J.

After incubating aliquots at room temperature for 1 h, we positioned aliquots in 3 ml methanol/acetone solution (4 : 1) and extracted each aliquot using the same methods for each antler stage. Sambur deer of India also have beautiful manes. Kierdorf and Kierdorf [32] noted that antlers are generally casted after the rutting/mating season, while Price et al. As the second step, the 125I testosterone RIA antibody kit was validated for sambar deer. At this stage the deer will carry his antlers for a few months until there is an intensive calcification at the base of the main beam below the coronet. These are situated on the skull directly between the ears. This is the first time that fecal testosterone concentration was monitored by using radioimmunoassay (RIA) related to antler stages in wild sambar deer populations in the region. The complete shedding of velvet took about 5-6 days. Old sambars turn very dark brown, almost the color black. In order for sambar stags to potentially grow big long antlers the age class needs to be there. The coat of a Sambar Deer forms a rough dark brown layer around its neck. Injury to the deer can also affect antler growth. Lateral section through the main beam showing the trabecular bone core, surrounded by denser cortical bone. This study is aimed at evaluating the relationship between endogenous testosterone levels and antler development in male sambar deer (Rusa unicolor unicolor) inhabiting the Horton Plains National Park, Sri Lanka. Laboratory support from Trinity College, Kandy, Sri Lanka, and valuable comments and suggestions from anonymous reviewers and the editor are also acknowledged. As in many other deer, only the male sambar deer has antlers. The tines from the backwards-pointing branch of the antlers are considerable smaller than the forwards pointing tines. Sambar Deer are dark brown in color and attain a height of 102 cm to 160 cm (40 to 63 inches). A4. Casting stage, which correspond to low concentration of fecal testosterone did not last long for a given individual, which will be over within a maximum of three days. Distribution. Large males weight up to 270–280 kg. In order to validate the samples, 10,000 cpm of 125I testosterone was added to 0.2 g of dry feces of sambar deer. Antlers are grown from January to March, hardening between June and November and cast in November/December. The Sambar lives in the woodland areas, alone or in small groups. Sambar Deer are light brown or dark with a grayish or yellowish tinge.The underparts are paler. Rusa Deer are distinguished by their large ears, the light tufts of hair above the eyebrows, and antlers that appear large relative to the body size. Sambar Deer also shed their antlers each year, typically after mating season. Changes in testosterone concentration, diameter of the testicles and mass of the body have been studied in relation to the antler cycles of such deer stags [9]. Any of the seven stages of the antler cycle could be observed at any given point of time during the year, indicating no marked seasonality in antler cycle among the sambar deer in the HPNP [5, 14]. Sambar (Rusa unicolor unicolor) is the most widely spread deer in the Asian continent [1]. Habitat of the Indian Sambar. The fecal testosterone levels of the seven antler stages of male sambar deer in the HPNP tested by RIA indicate a strong relationship of testosterone with different stages of the antler cycle. Start at the inside of the left main beam and measure to the inside of the right main beam. The underlying raw data used to support the findings of this study are available from the corresponding author upon request. obs.). This hypothesis could explain why males of some cervid species living in tropical and subtropical areas, including pampas deer (Ozotoceros bezoarticus), have well-defined and synchronous antler cycle, even though sexual activity may happen throughout the year. Binomial name: Rusa unicolor, Robert Kerr, 1792 The sambar (Rusa unicolor) is a large deer native to the Indian Subcontinent, southern China and Southeast Asia. The Indian Sambar deer’s antlers have 6 tines, and are strongly pearled. Estimating the hormone levels using fecal steroid assays provides a noninvasive method, which have the capacity to develop long-term means of determining adrenocortical, testicular hormones in many vertebrate taxa [12]. However, Ditchkoff et al. long. All of our grades of Sambar Stag are hand selected and carefully paired for shape, texture, color, amount of pith, and overall quality. Dec 8, 2014 - Explore Ina's board "Sambar deer" on Pinterest. Then, a testosterone tracer of 18,000 cpm 125I was added to each aliquot. Seven antler growth stages of sambar were documented based on phenotypic observations for the first time in Sri Lanka as (a) cast, (b) growing 1—single spike, (c) growing 2—antler fork into a Y as the second tine appears, (d) growing 3—velvet begins to harden as the third tine appears, (e) growth completed—velvet shedding begins, (f) hard antler, and (g) casting. We ensured that fecal samples were collected less than half an hour of voidance and kept in ice, in order not to let bacterial metabolism start affecting the concentration of fecal hormones. This shuts off the blood supply through the middle of the antler. The Manawatu population occurs along the coastal belt between Levin and Harakeke, and inland along the Turakina and Whangaehu Rivers. Sambars have thick coats of fur, giving them an elk-like appearance. obs.). They are incredibly interesting and unique creatures – learn more about them below. D. S. Weerasekera, S. J. Perera, D. K. K. Nanayakkara, H. M. S. S. Herath, A. N. L. Rathnasekara, K. B.

When the antler is nearing growth completion, a ring of bone is formed (Coronet) at its base just above the junction with the pedicle. Antlers are true bone and are a single structure. In deer testicular atrophy, the epididymis was comparatively larger than testes [7]. Rifle and calibre. The length of antlers can reach up to 110 centimeters upon maturity. Caribou are the only deer species where females grow antlers also. The argument by Shipka et al. Image courtecy of www.wildlifeonline.me.uk. While less powerful cartridges can do the job, most serious sambar hunters look at the 30 calibre cartridges and up. Caribou are the only deer species where females grow antlers also. Initially, we validated a practical and appropriate procedure for monitoring fecal testosterone in sambar deer stags, followed by the establishment of a relationship between antler stages and fecal testosterone concentration for the unique wild population of sambar deer in the HPNP, further attempting to record any seasonality of the testosterone levels in sambar males. Copyright © 2020 D. S. Weerasekera et al. However, other experiments show a relationship between the testicular volume and the growth of the antlers [7]. Determine the number of points on each antler by counting. Much of the knowledge on reproductive biology of the deer family (Mammalia: Artiodactyla: Cervidae) has been originated from studies of temperate species that exhibit a distinct seasonal cycle of reproductive behavior and antler growth in males [2]. This is an unusual pattern for deer, which more commonly live in larger groups. Nevertheless, the sambar population in the Horton Plains National Park (HPNP) is unique among other such populations in India and Sri Lanka by (a) aggregating into large herds counting to about 20 individuals in average opposed to general herd size of two to four and (b) by being predominantly grazers as opposed to the browsing behavior shown elsewhere [14]. The minimum legal calibre in Victoria for hunting Sambar deer has a minimum diameter of.270 using no less than a 130-grain projectile. [23] and Sankar and Acharya [24] strongly suggests this seasonality to be diffused in the tropics, recommending a reinvestigation on Heckeberg’s observation. The seasonality in the antler cycle in herds of red deer in the temperate region is well established by Wilson et al. Distribution of fecal testosterone concentration (ng g, Box and whisker plots for mean fecal testosterone levels in ng g, The Antler Cycle and Fecal Testosterone of Male Sambar Deer, Postgraduate Institute of Science, University of Peradeniya, Peradeniya, Sri Lanka, Department of Natural Resources, Faculty of Applied Sciences, Sabaragamuwa University, Belihuloya, Sri Lanka, Nuclear Medicine Unit, Faculty of Medicine, University of Peradeniya, Peradeniya, Sri Lanka, Epsilon Crest Research, 6/6.67 Ward Place, Colombo 07, Sri Lanka, Department of Zoology, Faculty of Science, University of Peradeniya, Peradeniya, Sri Lanka, Growing 2—antler fork into a Y as the second tine appears, Growing 3—velvet begins to harden as the third tine appears, P.

Review articles are excluded from this waiver policy. From the coast to the highest ranges in the divide they have colonized and conquered with ease. The tines from the backwards-pointing branch of the antlers are considerable smaller than the forwards pointing tines. These antlers have three points, or tines, and can typically grow up to 120 centimetres in length in adults. Sambar deer in Australia have had an immense journey of success and there have been many developments with their spread and expansion across all suitable habitat. ----- Join the Discord! A. Estevez, F. Ceacero, L. Gallego, and A. J. Garcia, “Biometrics, testosterone, cortisol and antler growth cycle in Iberian red deer stags (, S. S. Ditchkoff, L. J. Spicer, R. E. Masters, and R. L.

Handlos, “Fatal deer attack in a rutting season,”, G. A. Lincoln, H. M. Fraser, and T. J. Fletcher, “Induction of early rutting in male red deer (. Record Trophy Not all stags will produce perfect antlers each year or even during their entire life. Suitable calibres include .270, 7mm-08, 30’06, .308 and .303. The Indian Sambar has large eye glands, which enhance the impressive appearance of its head. Velvet shedding was preceded by an increase in the testosterone level, and it is the sudden drop in the testosterone concentration which triggers the antler casting. Rusa Deer are distinguished by their large ears, the light tufts of hair above the eyebrows, and antlers that appear large relative to the body size. The Sambar lives in the woodland areas, alone or in small groups. [23] that “sexual and antler cycles of deer species near the equator, where day length differs only slightly, are asynchronous” is supportive of our findings on sambar deer stags in the HPNP. They also feed on seedlings, fruit or seeds of many plants. Antler growth categories were identified by physical appearance of the antlers, especially the number of tines per antler and the length of the main beam [17], while the old males with irregular antler casting were not taken to the experiment. For the assay, we calculated variance coefficients for all the samples intra- and inter-assay. When antler growth is complete the ring or coronet will constrict thus reducing the blood flow. Because of it's density, strength, rough "gnarly" texture, and deep brown, sometimes even amber coloring, Sambar stag is highly prized for knifemaking. Sambar deer are either crepuscular (active at dusk and dawn) or nocturnal (active during the night) animals. Sambar Deer are light brown or dark with a grayish or yellowish tinge. The loosening of the antler prior to casting would seem to be a very sudden process as separation of the antler from the pedicle may be caused by as little as a sudden movement of the deer’s head. The shedding of velvet was also accompanied by an increase in the level of testosterone which emphasized its function. We thank the Department of Wildlife Conservation in Sri Lanka for permission to conduct our study in the Horton Plain National Park under the research permit number WL/3/2/10/18. Further, the relationship between the antler growth has been examined with hormones secreted by testes in different antler stages [4]. Antlers are casted and regrown from a blastema annually into three-branched structures of cartilage and bone that are used for sparing and attraction in adult sambar deer [4]. Large males weight up to 270–280 kg. properties, but Formosan Sambar deer antlers stem cells have not been extensively studied. The Sambar Deer is often confused with the Elk due to the bulky body and long, thin legs. Measure the antlers from tip to tip to determine the spread. The males live alone for much of the year, and the females live in small herds of up to 16 individuals. Antlers develop from two permanent stumps of bone referred to as Pedicles. The results obtained in this study were in agreement with similar research work carried out in other species of deer which were primarily with temperate origins, despite lacking a pronounced seasonality. After incubation at room temperature for 1 h, we continued with the extraction of testosterone from solid-phase by following methanol extraction [20]. This is the reason that antlers have grooves and pearling. As a result the more pearled and grooved the antlers are, the more abundant the blood supply was. The length of antlers can reach up to 110 centimeters upon maturity. on average. Antler Facts – Like all deer, sambars shed their antlers every year.
