| dc.description.abstract | The study was conducted in three upazila at Dinajpur district of Bangladesh from June 2016 to
May 2017. To investigate the productive and reproductive performances of Black Bengal goat
along with prevalence of different goat diseases in a smallholder farm. A total of 32 houses from
three areas were surveyed and found total 196 goats where 113 were female and 83 male. The
productive and reproductive performance of 36 adult (>12 months) female goats out of 196 goat
population was explored for the study. The average milk production of goats in Birganj, Sadar
and Birol upazilas were found 787.50±79.33, 495.83±149.05 and 304.17±14.38 ml/day,
respectively. The average milk production of goats in Sadar is 495.83±149.05 ml/day and at
Birol upazila is 304.17±14.38 ml/day were statistically similar but at Birganj the production is
787.50±79.33 ml/day, which was higher among the three areas. The average lactation length of
goats of Birganj, Sadar and Birol upazilas were found 121.67±10.06, 88.33±5.75 and
111.67±5.20 days, respectively. The average lactation length was highest 121.67±10.06day in
Birganj among the three upazilas. The average body weight of goats of Birganj, Sadar and Birol
upazilas were found 13.08±3.27, 17.17±3.25 and 15.33±2.80 kg, respectively. The average body
weight of goats of the selected three upazilas did not differ significantly. The average age at
puberty and age at 1st kidding of the selected goats in three upazilas was not differ significantly.
The average age of puberty of goats of Birganj, Sadar and Birol upazilas were found 8.25±0.69,
8.00±0.86 and 7.00±0.43 months, respectively. The average age at 1st kidding of goats of three
upazilas were found 14.25±0.69, 14.00±0.79 and 13.00±0.43 months, respectively. The average
post partum heat period of goats of three upazilas was 3.08±0.53, 3.92±0.50 and 2.67±0.40
months, respectively. The diseases were recorded mainly on the basis of history, clinical signs
and laboratory examination. Highest prevalence rate (%) of diseases was diarrhoea (19.9) as well
as fever and anorexia (19.9) followed by pneumonia (13.8), bloat (11.2), contagious ecthyma
(11.2), mixed parasitic infestation (8.7), corneal opacity (3.0), anuria (3.0), mange (2.6),
anoestrus (2.0), abscess (1.5), abortion (1.5) and retention of placenta (1.5). Prevalence of
diseases was higher in adults (>1year) 43.3% than young goats (7-12months) 30.1% and kids (<6
months) 26.5%, respectively. Overall prevalence of diseases was highest in female (57.6%) than
male groups (42.3%). Higher prevalence of diseases was found in rainy season (43.4%) and then
winter (35.4%) and summer season (21.1%). The higher prevalence of diseases in traditional
rearing systems. The farmers were lack of knowledge for preventive health care and hygienic
management. The study suggests that hygienic management practices, adequate supply of
nutrients, vaccination and deworming programmes in smallholder rearing system of Black
Bangal goats at rural level will improve the production and reduce disease prevalence in goats. | en_US |
