Phenotypic plasticity of the body shape in wild and farmed common carp (Cyprinus carpio) using geometric morphometric method
The aim of this study was to investigate the body shape and morphological comparison between the populations of wild (marine) and farmed common carp using geometric morphology. For this purpose, 65 pieces of fish including 23 wild common carp and 42 farmed common carp were sampled. The samples were then photographed and 16 landmarks were identified on the images. Procrast analysis was used in o...
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 کاملPhenotypic 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 کاملFixing Multicollinearity Instability in the Prediction of Body Weight from Morphometric Traits of White Fulani Cows
Body weight and nine morphostructural characters (withers height, rump height, heart girth, body length, head width, cannon circumference, shoulder width, rump width and rump length) of 83 White Fulani cows aged 1.5-2.4 years old were used to study the problem of multicollinearity instability in the estimation of body weight from morphological indices. Pairwise phenotypic correlations indicated...
متن کاملPrediction of birth weights from body weights of newborns.
OBJECTIVE To evaluate the accuracy of prediction of birth weights from body weights of newborns till six days after birth. DESIGN Prospective follow-up. SETTING Four villages near Hyderabad. METHODS Weights of 47 newborns were recorded daily from the day of birth for seven days. The birth weights were regressed on the weights of the babies taken on the 2nd day to the 7th day. Specificity ...
