This study was conducted to determine inner egg quality characteristics using external egg quality characteristics and to select variables in order to obtain the simplest model using ridge, LASSO and elastic net. The goodness of fit values of the regression estimating equations for egg yolk weight were 58.34 %, 59.17 % and 59.11 % using the ridge, LASSO and elastic net methods, respectively; for egg albumen weight they were 75.60 % for ridge, 75.94 % for LASSO and 75.81 % for elastic net.

This study determined polymorphisms of the POU1F1 gene and their relationships to milk yield and components, litter size, birth weight, and weaning weight in goats. With the POU1F1/AluI locus, significant associations were found between genotypes with lactation milk yield and litter size. A significant relationship was determined between genotypes and birth weight and the POU1F1/PstI locus (p < 0.05). The POU1F1 gene can be used as a molecular marker for economic features.
This study was conducted to estimate the live weight of Hair goats from biometric measurements and to select variables in order to reduce the model complexity by using penalised regression methods, LASSO and Adaptive LASSO, for
γ = 0.5 and γ = 1. It was concluded that Adaptive LASSO (γ = 1) estimated the live weight with the highest accuracy for both male and female Hair goats when all the criteria were considered.
