چکیده مقاله :
The objective of this study was to evaluate genetic and phenotypic parameters for some reproductive traits of Black Bengal does. Genetic parameters were estimated by Residual Maximum Likelihood procedure, fitting an animal model ignoring maternal genetic or permanent environmental effects. The least-squares means of litter size at birth (LSB), litter size at weaning (LSW), litter weight at birth (LWB), litter weight at weaning (LWW) and gestation length were 1.50, 1.29, 1.58 kg, 6.37 kg and 144.71 days, respectively. The effect of parity of doe was significant for LSB, LSW, LWB and LWW. In general, LSB, LSW, LWB and LWW increased with the progress of parity. The effect of season of kidding was significant for LSW, LWB and LWW. Estimates of heritability for LSB, LSW, LWB, LWW and gestation length were 0.08, 0.13, 0.10, 0.00 and 0.18, respectively. The low estimates of heritability obtained for reproductive traits indicated that selection based on the doe’s own performance may result in slow genetic improvement.
بز سیاه بنگال از ذخایر ژنتیکی و یکی از پتانسیل‌های ژنتیکی بنگلادش است. فراسنجه‌های ژنتیکی و فنوتیپی برای خصوصیات منی و رابطه آن با محیط بیضه در بز نر سیاه بنگال در این آزمایش برآورد شد. فراسنجه‌های ژنتیکی توسط روش حداکثر درست‌نمایی باقی‌مانده برآورد شدند و مدل حیوانی که اثرات ژنتیک مادری یا اثرات محیطی دایمی را نادیده می‌گرفت برازش شد. میانگین‌های حداقل مربعات حجم منی (میلی‌لیتر در هر انزال)، غلظت اسپرم (109 سلول در میلی‌لیتر)، تحرک توده (درصد)، زنده‌مانی اسپرم (درصد) و اسپرماتوزوآی طبیعی (درصد) به‌ترتیب 56/0، 55/2، 7/79 و 5/90 بود. فصل جمع‌آوری و محیط بیضه به‌طور معنی‌داری بر تمامی خصوصیات مطالعه شده اسپرم موثر بودند. سن بزهای نر بر تمامی خصوصیات مطالعه شده اسپرم به‌جز تحرک توده موثر بود. وزن‌ب دن اثر معنی‌داری بر حجم منی و تحرک توده داشت. برآورد وراثت‌پذیری برای غلظت اسپرم (38/0) متوسط و برای حجم منی، تحرک توده، زنده‌مانی اسپرم و اسپرماتوزوآی طبیعی (05/0 تا 18/0) کم بود. همبستگی فنوتیپی در دامنه اندکی منفی (001/0-) تا مثبت (42/0) و همبستگی ژنتیکی در دامنه متوسط منفی (37/0-) تا خیلی مثبت (99/0) بود. غلظت اسپرم تنها صفت بز سیاه بنگال است که ممکن است طی انتخاب، پیشرفت ژنتیکی منطقی داشته باشد. انتخاب برای افزایش محیط بیضه باید پاسخ مرتبط مطلوبی با خصوصیات منی داشته باشد.
