To assess the value of DNA fingerprints for the prediction of heterosis in chickens, retrospective analyses of data from three crossbreeding experiments and DNA fingerprints (DEP) of parental strains were conducted using two minisatellite and one middle-repetitive DNA probes. DEP bands were assessed on pooled DNA samples of 10-15 individuals per parental genetic group. The number of DEP bands e...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
The present study aimed to estimate the genetic for parameters of biometric traits in Iranian Moghani-sheep breeds. The data set consisted 15115 biometric records from 3702 individual progenies of 499 male and 3203 female, involve for a 15 years period (1996 to 2011). obtained from Moghani sheep breeding and raising station. Variance components and genetic parameters were estimated using ...
the purpose of this study was to investigate the relationship of maternal breeding values of the weight of day-old chick chicks in a commercial broiler line with egg traits including yolk fatty acids. maternal breeding values of 63 hens of known pedigree were estimated through an animal model, containing direct additive genetic effect, maternal additive genetic effect, maternal common environme...
Tench an economically important species in Anzali Lagoon has experienced a sharp catch decline in recent years. The present study aims at examining certain biological traits of the fish in Anzali lagoon. A sample of 96 pieces of such fish were netted out through gillnet fishing during Jan 2006-July 2007. The findings showed incongruity in 11 out of 36 morphometric traits followed by 1 out of 1...
(Co)variance components and genetic parameters of weight at birth (BWT), weaning (3WT), 6, 9 and 12 months of age (6WT, 9WT and 12WT, respectively) and first greasy fleece weight (GFW) of Bharat Merino sheep, maintained at Central Sheep and Wool Research Institute, Avikanagar, Rajasthan, India, were estimated by restricted maximum likelihood, fitting six animal models with various combinations ...
The data on 6772 growth records of Sirohi goats maintained at All India Coordinated Research Projecton Sirohi goat at Livestock Research Station, Vallabhnagar, Udaipur, India, and recorded between 2004 and 2016, were analysed to study the growth related traits and their genetic control. The overall least squares means of body weight at birth, W3M, W6M, W9M, W12M, were 2.34 ± 0.03, 12.44 ± 0.19,...
the objective of the present study was to estimate the lactation curve parameters through incomplete gamma function and to genetically evaluate the relationship of these parameters and udder traits in holstein population of iran. two data sets' including 117583 [(for lactation curve parameters) and 7351 (for determining genetic and phenotypic relationship between lactation curve parameters...
In this study, it was aimed to determine the internal and external quality traits of the Guinea fowl eggs as well as the phenotypic correlation among the these traits. Totally 100 Guinea fowl eggs were collected in three sequential days were used for this study. The birds were housed at Poultry Research Unit of the Department of Animal Science, Faculty of Agriculture, University of Akdeniz. Val...
In this study, selection strategies were simulated to find optimal selection strategy in Japanese quails. Breeding goal was consisted of body weight and egg weight traits. Effects of using genetic markers related to carcass weight were investigated by five different selection strategies. In this case, breeding goal included body weight, egg weight and carcass weight. Deterministic simulation, b...
