MORPHOMETRIC CHARACTERIZATION OF BLACK BENGAL GOAT AT SAVAR GOAT DEVELOPMENT FARM UNDER FARMING CONDITION

Abstract

The study was undertaken to characterize Black Bengal goat (BBG) under farming condition. Data on different parameters were collected during January 2019 to December 2019 at Savar Goat Development Farm. A total of 60 animals of different ages from three months to more than 12 months of both sexes were included. All type of measurements was taken when goats standing freely. All measurements were taken in metric unit. Body length were higher in males 34.05±0.069, 41.60±1.2 and 49.10±0.98 cm than that of females 29.70±0.82, 37.20±0.90 and 45.80±1.17 cm for age groups 3-6, 6-12 and >12 months of age. Male goats had higher heart girth 40.81±0.37, 51.86±0.30 and 55.43±0.19 cm than that of female goats 39.59±0.13, 48.57±0.25 and 53.32±0.37 cm irrespective of age. Average adult (>12 months’ age) body weight of male and female goats as 16.00±0.14 and 13.51±0.09 kg, respectively. Wither height was higher in adult males 36.14±0.37, 46.55±0.81 and 52.90±0.60cm than females 34.67±0.30, 42.83±0.78 and 49.33±0.30 cm for same age. Tail length of Black Bengal goats ranged from 7.45±0.15 to 10.37±0.15 cm for different age and sex group. Average male foreleg length in >12 months of age possessed higher than that of female. Average udder length of BBGs were 6.87±0.27, 8.52±0.29 and 11.59±0.25 cm and breadth were 4.34±0.18, 6.58±0.16 and 8.00±0.16 cm, respectively for age groups 3-6, 6-12 and >12 months of age. The average scrotal length of Black Bengal bucks at 3-6, 6-12 and more than 12 months were 5.80±0.24, 9.26±0.16 and 11.19±0.32 cm respectively. Whereas, all the findings gradually increased for all parameters according to their different age groups. Body weight has been a positive correlation with body length, heart girth, wither height, scrotal length. All the parameters studied found comparatively higher in buck than in does and it increased linearly with increasing ages.
