چکیده مقاله :
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 ageat puberty of Jamunapari, Black Bengal and crossbred goats were 335.00 ± 25.77,194.12 ± 18.73 and 287.50 ± 22.57 days, respectively. Ageat first conceptionof Jamunapari, Black Bengal and crossbred goats were 381.00 ± 22.54, 217.94 ± 16.87 and 321.25 ± 21.25 days,respectively. Ageat first kiddingof 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.
مطالعه حاضر در جهت ایجاد شناخت و آگاهی از عملکرد تولیدی و تولیدمثلی بزهای جاموناپاری، سیاه بنگال و آمیخته‌های آنها در منطقه چیتاگنگ در طی دوره ماه می تا دسامبر سال 2012 صورت گرفت. داده‌های صفات تولیدی و تولیدمثلی از روی 324 بز جمع‌آوری شد. در مطالعه حاضر، وزن تولد بزهای جاموناپاری نسبت به آمیخته‌های دیگر بالاتر بود. وزن هنگام بلوغ بزهای نر و ماده جاموناپاری، سیاه بنگال و آمیخته‌های آنها به ترتیب 53/3 ± 70/50، 67/1 ± 27/24 و 53/2 ± 38/40 و 78/3 ± 47/45، 33/2 ± 06/21 و 97/2 ± 72/35 کیلوگرم بود. بیشترین تولید شیر و دوره شیردهی در بزهای جاموناپاری مشاهده شد. میانگین سن بلوغ بزهای جاموناپاری، سیاه بنگال و آمیخته‌های آنها به ترتیب 77/25 ± 00/335، 73/18 ± 12/194 و 57/22 ± 50/287 روز بود. سن اولین آبستنی در بزهای جاموناپاری، سیاه بنگال و آمیخته‌های آنها به ترتیب 54/22 ± 00/381، 87/16 ± 94/217 و 25/21 ± 25/321 روز بود. سن اولین زایش بزهای جاموناپاری، سیاه بنگال و آمیخته‌های آنها 58/24 ± 00/534، 96/16 ± 12/368 و 25/21 ± 25/471 بود. فاصله بین دو زایش بزهای سیاه بنگال پایین‌تر بود، یعنی عملکرد تولیدمثلی در بزهای سیاه بنگال نسبت به بزهای جاموناپاری و آمیخته‌های آنها بهتر بود. دوره آبستنی بزهای جاموناپاری، سیاه بنگال و آمیخته‌های آنها به ترتیب 19/8 ± 71/151، 61/7 ± 72/146 و 74/7 ± 85/147 روز بود.
