ABSTRACT
The phenotypic appearance of the head of animal species depends strongly on the shape of the skull. The morphometric studies of the skull show that variability in the shape and proportions of bones is influenced by genetic and environmental factors. The present study was carried out first time on the morphometrical characteristics on skull of Indian Blackbuck. Craniometric measurements for 48 different parts of the skulls of Indian blackbuck were made in this study. All investigated features were expressed as Mean±SE. The craniometric measurements and cephalic indices had been compared with ruminants. The mean lengths of the skulls were found to be 20.68±0.02 cm, with the width and cephalic index to the magnitude of 9.54±0.03 cm and 46.12±0.12 cm, respectively. The cranial length, width and height in blackbuck were 10.40±0.02 cm, 6.13±0.02 cm and 7.13±0.02 cm, respectively. The cranial index was 59.00±0.11. The mean facial length, facial width and facial index were 11.53±0.08 cm, 9.30±0.01 cm and 80.67±0.44 cm, respectively. The mean weight of the skull with mandible in blackbuck was 182.37±0.54.
RESUMEN
La apariencia fenotípica de la cabeza de especies animales depende principalmente de la forma del cráneo. Los estudios morfométricos del cráneo muestran que la variabilidad en la forma y proporciones de los huesos está influenciada por factores genéticos y ambientales. El presente estudio se llevó a cabo por primera vez en las características morfométricas en el cráneo del antílope indio. En este estudio se efectuaron mediciones craneométricas en 48 partes de los cráneos de antílope indio. Todas las características investigadas se expresaron como Media±EE. Las mediciones craneométricas e índices cefálicos fueron comparados con los rumiantes. Se encontró que las longitudes medias de los cráneos eran de 20,68±0,02 cm, con el ancho y el índice cefálico de 9,54±0,03 cm y 46,12±0,12 cm, respectivamente. La longitud del cráneo, ancho y alto en antílope indio eran 10,40±0,02 cm, 6,13±0,02 cm y 7,13±0,02 cm, respectivamente. El índice craneal era 59,00±0,11. La longitud media del rostro, ancho facial e índice facial eran 11,53±0,08 cm, 9,30±0,01 cm y 80,67±0,44 cm, respectivamente. El peso medio del cráneo con la mandíbula en el antílope indio fue de 182,37±0,54.
