“…In contrast, the skull was mesaticephalic in dog (Miller et al), brachycephalic in tiger (Joshi, 2004) and mesocephalic in Malayan sun bear (Kalita et al, 2019). The skull index was 47.82±0.05 in the present study, whereas the same measurement was 53.57 cm in Mehraban sheep (Karimi et al, 2011), 38.23±0.85 in donkey (Zhu et al ., 2014), 47.77±1.96 in Markhoz goat (Goodarzi & Hoseini, 2014), 46.12±0.12 cm in blackbuck (Choudhary & Singh, 2015b), 46.51±0.29 cm in dromedary camel , 70.56±0.22 in wild pig (Choudhary et al ., 2017), 53.56±0.11 in Zovawk pigs (Choudhary et al, 2019b) and 80.48 in Malayan Sun bear (Kalita et al).…”

The present study was designed to elaborate on the morphometry of the skull of non-descript goats in Mizoram state of India. The study was conducted on the skull of twelve (n=12) adult goats of either sex (n=6 males and n=6 females) collected from the local slaughterhouses. Altogether, forty-one different measurements were taken morphologically. In the present study, the cranial and facial bones were the major components of the skull with a total of thirty-two bones. There were three single and four paired cranial bones with a total of eleven bones. There were one single and the rest were paired facial bones with a total of twenty-one bones. The cranial bones were occipital, parietal, interparietal, sphenoid, ethmoid, frontal and temporal. The facial bones were maxilla, premaxilla (incisive), palatine, pterygoid, nasal, lacrimal, zygomatic (malar), vomer, turbinate, mandible and hyoid. The skull measurements showed that the skull of the goat was elongated and dolichocephalic as per the cephalic index (47.82±0.05). The length and width of the skull was 19.28±0.03 cm and 9.22±0.04 cm, respectively. There were two supraorbital foramina on both sides of the frontal bone. The prominent facial tuberosity lies dorsally to the third superior premolar tooth. Single infraorbital foramen was located dorsally to the junction of the first and second superior premolar teeth on maxilla bone. The orbits were round and complete and situated on a frontolateral oblique plane. It can be concluded that the findings of this study would assist the comparative studies with other domesticated animals in the future and would be applicable in clinical veterinary practice and even in zooarchaeology.

Background: There is scanty information on the morphometry of the skull of Indian mithun; therefore, the present study was designed to provide morphometric data of the skull of Indian mithun. Methods: The study was conducted on the skull bones of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland states of India from September, 2019 to March, 2020. In the present study, altogether, a total of forty-five parameters were taken in the skull bones of males and females of Indian mithun. Result: The biometrical observations on the different parameters of the skull of Indian mithun were found to be significantly (P less than 0.01, P less than 0.05) higher in the males than females. The measurements demonstrated that the skull of the mithun was elongated and dolichocephalic as per the value of the skull index. The skull index/ cephalic index was 48.76±0.03 in males and 48.71±0.02 in females of the mithun. The length, width of the skull was 44.52±0.02, 44.41±0.02 in males and 21.62±0.04, 21.57±0.05 in females of mithun, respectively. The orbital margin was circular and complete in mithun. The cranial cavity of mithun was oval in outline with a capacity of 530.00±0.27 cm3 in males and 523.00±0.31 cm3 in females. The foramen magnum was large, roughly oval with a foramen index as 96.93±0.06 in males and 97.19±0.04 in females. The present morphometrical studies on the skull of mithun can be useful to the wildlife professionals and zoo veterinarians for the determination of sex of this animal and distinguish from other domestic and wild animals for solving veterolegal cases.

Zovawk is newly identified breed of pig of Mizoram approved by breed registration committee of Indian Council of Agricultural Research (ICAR), New Delhi. This study was designed to provide maximum number of morphometrical parameters of skull and some valuable information on clinically important parameters of Zovawk. The skull of the Zovawk was dolichocephalic according to the cephalic index (53.56±0.11). The supraorbital foramina distance, infraorbital foramina distance, skull length, skull width, cranial length and nasal length of the Zovawk were 3.49±0.01 cm, 6.55±0.01 cm, 28.26±0.03 cm, 15.11±0.26 cm, 13.17±0.04 cm and 13.79±0.02 cm, respectively. The orbital margins were found to be incomplete with bilateral variation among the orbits of both the sides. The distance from the process of alveolar socket of canine tooth to the infraorbital canal and from the latter to the root of the fourth upper premolar alveolar tooth directly ventral to it was 4.77±0.04 cm and 1.20±0.01 cm, respectively in Zovawk. The data are of clinical importance as a guide for tracking the infra-orbital nerve, and necessary for its desensitization during the manipulations in the skin of the upper lip, nostril and face at the level of the foramen. The distance between the lateral end of the alveolus of the third incisor tooth to the mental foramen was 3.57±0.04 cm in Zovawk, which is an important landmark for achieving the location of the mental nerve for the regional nerve block Zovawk. The length and height of the mandible were 25.02±0.09 cm and 10.54±0.07 cm, respectively in Zovawk. The morphometric measurements of the skull and applied anatomy of the head region of the Zovawk provide an important baseline data for further research in the field of applied anatomy.
