چکیده مقاله :
The present research was designed to examine the genetic analysis of egg weight, egg yolk weight and egg albumen weight of Bovan Neva Black laying hens at 25, 51 and 72 weeks. For this purpose, thirty birds were selected from the layer flock in the Babcock University Teaching and Research Farm. They were individually housed in separate labeled battery cage. A total of thirty eggs were collected daily from the birds continuously in five days of egg production, at each age of 25, 51 and 72 weeks. The total number of eggs collected at each age were 150. Data collected for egg weight, egg yolk weight and egg albumen weight were used to evaluate the descriptive statistics, influence of age and Pearson correlation coefficient on different age groups. The mean values of the traits revealed a consistent increase in egg weight 55.02-63.29 g, egg yolk weight 13.14-19.39 g and egg albumen weight 35.52-39.21 g by aging. A significant positive genetic correlation was obtained among traits with linear regression equations at different age groups. Restricted maximum likelihood (REML) of Wombat software was used to obtain the repeatability and heritability estimates. From the results, it was revealed that all the traits recorded high estimates of heritability and repeatability while egg weight is more heritable and repeatable than egg yolk weight and egg albumen weight indicating that fewer records would be required to adequately characterize the inherent production ability of each trait as laying age progressed.
تحقیق حاضر با هدف آنالیز ژنتیکی وزن تخم­مرغ، وزن زرده تخم ­مرغ و وزن آلبومین تخم ­مرغهای تخمگذار بوان نرا سیاه در هفته­های 25، 51 و 72 صورت گرفته است. برای این منظور، 30 پرنده از گله­های تخمگذار مزرعه آموزشی و تحقیقاتی دانشگاه باب­کوک انتخاب شدند. این مرغ­ها به صورت انفرادی در قفس­های باتری جداگانه شماره­گذاری شده نگهداری گردیدند. تمامی 30 تخم ­مرغ تولید شده به صورت روزانه از پرنده­ها در پنج روز متوالی تولید تخم در هر کدام از سن­های 25، 51 و 72 هفتگی جمع­آوری گردیدند. تعداد کُل تخم ­مرغ­های جمع­آوری شده در هر سن، 150 عدد بود. داده­های جمع­آوری شده برای وزن تخم، وزن زرده تخم و وزن آلبومین تخم برای ارزیابی آماره­های توصیفی، اثر سن و ضریب همبستگی پیرسون روی پروه­های سنی مختلف مورد استفاده قرار گرفتند. مقادیر میانگین این صفات نشان دهنده یک افزایش ثابت 29/63-02/55 گرمی در وزن تخم­مرغ، 39/19-14/13 گرمی در وزن زرده تخم و 21/39-52/35 گرمی در وزن آلبومین تخم با افزایش سن بوده است. همبستگی ژنتیکی مثبت معنی­داری بین صفات دارای معادلات رگرسیون خطی در گروه­های سنی مختلف به دست آمد. حداکثر درستنمایی محدود شده (REML) نرم­افزار Wombat برای به دست آوردن برآوردهای تکرارپذیری و وراثت­پذیری مورد استفاده قرار گرفت. نتایج حاصل نشان داد که همه صفات ثبت شده دارای برآوردهای بالایی برای وراثت­پذیری و تکرارپذیری بوده و وزن تخم­مرغ وراثت­پذیرتر و تکراپذیرتر از وزن زرده تخم و وزن سفیده تخم بوده است. این موضع نشان می­دهد که رکوردهای کمتری برای تعیین ویژگی­های تولیدی ارثی هر صفت همگام با افزایش سن تخم­گذاری لازم است.
