Preliminary Study on Productive and Reproductive Performances of Jamunapari, Black Bengal and Crossbred Goats at Chittagong Region of Bangladesh

The present study was conducted with a view to know the productive and reproductive performance of Jamunapari, Black Bengal and crossbred goats in Chittagong district during the period of May to December 2012. The data on productive and reproductive traits were collected from 324 goats as a whole. In the present study, the birth weight of Jamunapari goats was higher than other crosses. The adult weight of Jamunapari, Black Bengal and crossbred bucks and does were 50.70 +/- 3.53, 24.27 +/- 1.67 and 40.38 +/- 2.90 kg and 45.47 +/- 3.78, 21.06 +/- 2.33 and 35.72 +/- 2.97 kg, respectively. The highest milk yield and lactation period were observed in Jamunapari goats than other crosses. The average age at puberty of Jamunapari, Black Bengal and crossbred goats were 335.00 +/- 25.77, 194.12 +/- 18.73 and 287.50 +/- 22.57 days, respectively. Age at first conception of Jamunapari, Black Bengal and crossbred goats were 381.00 +/- 22.54, 217.94 +/- 16.87 and 321.25 +/- 21.25 days, respectively. Age at first kidding of Jamunapari, Black Bengal and crossbred goats were 534.00 +/- 24.58, 368.12 +/- 16.96 and 471.25 +/- 21.25 days, respectively. The kidding interval of Black Bengal goat was lower i.e. the reproductive performance is better in Black Bengal goat than Jamunapari and crossbred goats. Gestation period of Jamunapari, Black Bengal and crossbred goats were 151.71 +/- 8.19, 146.72 +/- 7.61 and 147.85 +/- 7.74 days, respectively.
