Iranian native hens are a valuable genetic resource, due to their adaptability to harsh conditions of husbandry and environment in rural area. The genetic parameters for various traits of economic importance were studied in an Iranian Native chicken population under short term selection for egg production and body weight for over 2 years. The parameters studied were body weight at day old (BW1)...

The objective of the present study was to estimate heritability values for some performance and egg quality traits of native fowl in Isfahan breeding center using REML and Bayesian approaches. The records were about 51521 and 975 for performance and egg quality traits, respectively. At the first step, variance components were estimated for body weight at hatch (BW0), body weight at 8 weeks of a...

A total of 625 progenies New Zealand White rabbits, kept at Sakha Experimental Rabbits, Kafr-El-Sheikh, Government, belonging to Animal production Research Institute, Ministry Agriculture, Dokki, Cairo, Egypt, during 2010-2017 were used estimate the genetic parameters and phenotypic trends for some reproductive productive traits. Traits studied litter size birth (LSB), weight (LWB), kit body fo...

Identification of genes determining the expression of economically important traits of plants and animals is a main research focus in agricultural genomics. Most of these traits are characterized by a wide variability of the expression of genes at certain loci called quantitative trait loci (QTL). Characterization of the chromosomal regions carrying QTL can be applied in marker-assisted Selecti...

The main aim of this research was to estimate the genetic and phenotypic parameters for productive and reproductive traits of Esfahan native chickens. Traits included body weights at hatch (BW1), 8 weeks of age (BW8), 12 weeks of age (BW12), and at sexual maturity (WSM)], age at sex maturity (ASM), egg number (EN), average egg weight (AEW) in the first 12 weeks of production, and egg production...

هدف از پژوهش کنونی مقایسه استراتژی‌های اصلاح نژاد در گله­ مرغ بومی مازندران به کمک شبیه­سازی رایانه‌ای بود. صفات شبیه‌سازی­شده، وزن بدن در زمان تولد (BW1)، هشت هفتگی (BW8)، دوازده هفتگی (BW12)، زمان بلوغ جنسی (BWM)، سن بلوغ جنسی (AFE)، وزن اولین تخم­ (EWM)، میانگین وزن تخم­مرغ در هفته­های 28 تا 32 (EW28-32) و تعداد تخم­مرغ (EN) بودند. در استراتژی اول خروس­ها بر اساس ارزش اصلاحی صفت BW12 و مرغ­ه...

We investigate multiple qubit Pauli groups and the quantum states/rays arising from their maximal bases. Remarkably, the real rays are carried by a Barnes-Wall lattice BWn (n = 2m). We focus on the smallest subsets of rays allowing a state proof of the BellKochen-Specker theorem (BKS). BKS theorem rules out realistic non-contextual theories by resorting to impossible assignments of rays among a...

The aim of this study is study the inheritance of economic traits in an Iranian Native chickens population by estimating genetic parameters (heritability, genetic, phenotypic and environment correlations) under short-term selection in breeding programs. Identification of genes determining the expression of economically important traits of plants and animals is a main research focus in agricultu...
