Genetic Analysis of Ewe Productivity Traits in Baluchi Sheep
The present study was carried out to estimate (co)variance components and genetic parameters for some productivity traits of Baluchi ewes. The data were collected during a 31 year period (1984-2014) at the experimental breeding station of Baluchi sheep, which is located in north-east of Mashhad, Iran. The analysis was based on 14030 records of lambs and 4371 records of ewes. Investigated traits...

هدف از این تحقیق یافتن ارتباط بین نحوه نگرش زبان آموزان به موفقیت و شکستشان و نوع شخصیت آنها است. 216 زبان آموز، 111 پسر و 105 دختر، در سطح متوسط که در آموزشگاه زبان انگلیسی شکوه مشغول به تحصیل بودند در این پژوهش شرکت کرده اند. شرکت کننده ها دو پرسشنامه neo-ffi و atfll را تکمیل کرده اند. نتیجه نشان داد که: احساسات با توافق پذیری و وظیفه شناسی ارتباط مثبت و با روان نژندی ارتباط منفی دارد. تصور ا...
15 صفحه اولHeritabilities and Genetic Correlations for Egg Weight Traits in Iranian Fowl by Multi Trait and Random Regression Models
Objective: The main objective of this research was estimation of genetic parameters for five consecutive measurements of egg weights in Isfahan fowl using multi trait model and random regression models. Methods: The statistical models included generation-hatch as a fixed effect, weeks of age as a covariate and additive genetic and individual permanent environmental effects as random effects. Th...

متن کاملOverberg research projects. X. Faecal egg counts in the interpretation of nematode worm burdens in sheep.
Worm egg counts were compared with nematode worm burdens from data collected from greater than 400 sheep killed in experiments on the epidemiology of nematode parasites in the Overberg, in the winter rainfall area of the southern Cape Province. Data were analysed in several ways but no method could be found to accurately estimate the number of nematodes present from the faecal egg count in resp...
