Phenotypic Correlations between Live Body Weight and Carcass Traits in Arbor Acre Breed of Broiler Chicken
This study was aimed at determining the relationship between live body weight and carcass traits in Arbor Acre broiler chicken. Fifty day-old broiler chicks were purchased and raised on deep litter system until 56 days of age. At maturity, ten birds were randomly selected for carcass evaluation. The analyzed data showed that live weight has statistically significant (P<0.01) positive phenotypic...
متن کاملGenetic variability of environmental sensitivity revealed by phenotypic variation in body weight and (its) correlations to physiological and behavioral traits
Adaptive phenotypic plasticity is a key component of the ability of organisms to cope with changing environmental conditions. Fish have been shown to exhibit a substantial level of phenotypic plasticity in response to abiotic and biotic factors. In the present study, we investigate the link between environmental sensitivity assessed globally (revealed by phenotypic variation in body weight) and...
متن کاملEstimation of genetic and phenotypic trends for body weight traits of sheep in Guilan province of Iran
The main objective of the present study was to estimate genetic and phenotypic trends for body weight traits in Guilan province sheep. Traits included were birth weight (BW, n=14,549), 3-month weight (3MW, n=13,109) and 6-month weight (6MW, n=10,141). Data and pedigree information used in this study were collected during 1994 to 2011 by the Agricultural Organization of Guilan province in Iran. ...
متن کاملMorphometric Traits and Correlation between Body Weight and Body Size Traits in Isa Brown and IlorinEcotype Chickens
Data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin Isa Brown and Ilorin ecotypechickens. The studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...
متن کاملestimation of heritability and genetic and phenotypic correlation between egg quality and body weight traits in native fowls of fars
a total of 2000 records of egg quality of 746 birds and body weight data from 17th generation of fars native fowl breeding station were used to estimate the genetic parameters of egg quality and body weight traits. six univariate animal models with different random effects were fitted for each trait. a model with direct additive genetic and maternal permanent environmental effects was the most ...
