Study on morphometric, productive and reproductive traits of native cattle at Sylhet district

Abstract

The morphometric, productive and reproductive traits of indigenous cattle at Sylhet district were studied. A wide variety of coat colours among the cattle of the selected areas was observed. Most of them were of roan colour. The body is small, compact and less fleshy. Wither height and hearth girth were 89.03±11.11 and 112.09±16.68 cm, respectively. The average body length was 119.85±16.96 cm and the chest width was 32.48±6.48 cm. The approximate body weight and horn size of the cattle were 162.77±60.99 kg and 3.94±4.05 cm, respectively. The milk production per day was 1.33±0.4 litres, lactation length was 187.94±14.77 days and the dry period was 220.81±15.68 days. Gestation length and calving interval were found to be 299.19±3.82 days and 453.47± 13.181 days, respectively. The mean age at first calving was 44±1.6 months. The productive and reproductive performances of native cattle of Sylhet district. More detailed studies are needed to recommend the morphometric, productive and reproductive performance of cattle in Sylhet district.

Identification and characterization of dwarf cattle available in Dinajpur district

“…The average wither height of Dwarf cattle: yearling bull, adult bull, heifer, cow, male calf and female calf were 85.6, 90.4, 82.8, 92.2, 63.1 and 63.3 cm, respectively. The wither height of indigenous cattle of Sylhet (Koirala et al, 2011) was (89.0 cm) almost similar with that of the present study. Al-Amin et al (2007) and observed almost similar wither height in North Bengal Grey cattle (91.0 cm) and non-descriptive cattle (84.6 cm) with Dwarf cattle.…”

“…The average horn length and diameter of Dwarf cattle: yearling bull, adult bull, heifer and cow were 3.25, 8.67; 4.82, 10.2; 3.67, 9.83 and 5.74, 8.21 cm, respectively. The horn size of native cattle of Sylhet was (3.94 cm) almost similar with that of Dwarf cattle (Koirala et al, 2011). Horn length and diameter of non-descriptive cattle in India were 18.1 and 11.4 cm, respectively .…”

“…Among the local cattle of Sylhet region, different coat colors were observed as 43. 4, 16.2, 12.5, 8.8, 7.6, 7.8, 3.0, 0.4 and 0.2% were roan, black, white, brown, dark brown, light brown, red, ash and cream coat color, respectively (Koirala et al, 2011).…”

“…also found similar heart girth (126.9 cm) in non-descriptive cattle. The heart girth observed in indigenous cattle of Sylhet region was 112.1 cm (Koirala et al, 2011).…”

“…Hadiuzzaman et al (2010) reported that the body length of Red Chittagong cows at 60 months of age was 108.3 cm which was higher than the result (106.9 cm) obtained by Bag et al (2010). Koirala et al (2011) observed that the body length of native cattle of Sylhet was 119.9 cm. Body length of non-descriptive cattle in India was 97.3 cm .…”
